    2014-09-01

    The Guide to Attic Air Sealing was completed in 2010 and although not in the standard Measure Guideline format, is intended to be a Measure Guideline on Attic Air Sealing. The guide was reviewed during two industry stakeholders meetings held on December 18th, 2009 and January 15th, 2010, and modified based on the comments received. Please do not make comments on the Building America format of this document. The purpose of the Guide to Attic Air Sealing is to provide information and recommendations for the preparation work necessary prior to adding attic insulation. Even though the purpose of this guide is to save energy - health, safety and durability should not be compromised by energy efficiency. Accordingly, combustion safety and ventilation for indoor air quality are addressed first. Durability and attic ventilation then follow. Finally, to maximize energy savings, air sealing is completed prior to insulating. The guide is intended for home remodelers, builders, insulation contractors, mechanical contractors, general contractors who have previously done remodeling and homeowners as a guide to the work that needs to be done.

    This report summarizes the first phase of a project to model the thermal performance of radiant barriers. The objective of this phase of the project was to develop a refined model for the thermal performance of residential house attics, with and without radiant barriers, and to verify the model by comparing its predictions against selected existing experimental thermal performance data. Models for the thermal performance of attics with and without radiant barriers have been developed and implemented on an IBM PC/AT computer. The validity of the models has been tested by comparing their predictions with ceiling heat fluxes measured in a number of laboratory and field experiments on attics with and without radiant barriers. Cumulative heat flows predicted by the models were usually within about 5 to 10 percent of measured values. In future phases of the project, the models for attic/radiant barrier performance will be coupled with a whole-house model and further comparisons with experimental data will be made. Following this, the models will be utilized to provide an initial assessment of the energy savings potential of radiant barriers in various configurations and under various climatic conditions. 38 refs., 14 figs., 22 tabs.

    IBACOS completed an initial analysis of moisture damage potential in an unvented attic insulated with closed-cell spray polyurethane foam. To complete this analysis, the research team collected field data, used computational fluid dynamics to quantify the airflow rates through individual airflow (crack) paths, simulated hourly flow rates through the leakage paths with CONTAM software, correlated the CONTAM flow rates with indoor humidity ratios from Building Energy Optimization software, and used Warme und Feuchte instationar Pro two-dimensional modeling to determine the moisture content of the building materials surrounding the cracks. Given the number of simplifying assumptions and numerical models associated with this analysis, the results indicate that localized damage due to high moisture content of the roof sheathing is possible under very low airflow rates. Reducing the number of assumptions and approximations through field studies and laboratory experiments would be valuable to understand the real-world moisture damage potential in unvented attics.

    Field studies in a hot, humid climate were conducted to investigate the thermal and hygrothermal performance of ventilated attics and non-ventilated semi-conditioned attics sealed with open-cell and with closed-cell spray polyurethane foam insulation. Moisture pin measurements made in the sheathing and absolute humidity sensor data from inside the foam and from the attic air show that moisture is being stored in the foam. The moisture in the foam diffuses to and from the sheathing dependent on the pressure gradient at the foam-sheathing interface which is driven by the irradiance and night-sky radiation. Ventilated attics in the same hot, humid climate showed less moisture movement in the sheathing than those sealed with either open- or closed-cell spray foam. In the ventilated attics the relative humidity drops as the attic air warms; however, the opposite was observed in the sealed attics. Peaks in measured relative humidity in excess of 80 90% and occasionally near saturation (i.e., 100%) were observed from solar noon till about 8 PM on hot, humid days. The conditioned space of the test facility is heated and cooled by an air-to-air heat pump. Therefore the partial pressure of the indoor air during peak irradiance is almost always less than that observed in the sealed attics. Field data will be presented to bring to light the critical humidity control issues in sealed attics exposed to hot, humid climates.

    A sealed or unvented attic is an energy-efficient envelope component that can reduce the amount of energy a house consumes for space conditioning if the air handler and/or ducts are located in the attic. The attic is typically sealed by using spray foam on the underside of the roof deck and covering the soffit, ridge and gable vents to minimize air leakage from the attic to the outside. This approach can save up to 10% in space-conditioning energy when ducts are located in the attic (DOE 2013). Past research done by ORNL and Florida Solar Energy Center suggests that in more hot, humid climates, an unvented attic could potentially create a more humid, uncomfortable living environment than a vented attic (Colon 2011, Boudreaux, Pallin et al. 2013). Research showed that controlling the higher indoor humidity could reduce the energy savings from the sealed, unvented attic, which in turn would decrease the energy savings payback. Research also showed that the roof assembly (5.5 inches of open-cell foam, 1inch of closed-cell foam, OSB, felt paper, and asphalt shingles) stored moisture, thus acting as a moisture buffer. During the fall and winter, the roof assembly stored moisture and during the spring and summer it released moisture. This phenomenon is not seen in a vented attic, in which the air exchange rate to the outside is greater and, in the winter, helps to dehumidify the attic air. It was also seen that in a vented attic, the direction of water vapor diffusion is on average from the attic to the interior of the house. Air leakage from the attic to the interior also occurs during more of the year in a house with an unvented attic than in one with a vented attic. These discoveries show that the moisture dynamics in a house with an unvented attic are much different from those in a house with a vented attic. This study reports on a series of computer model investigations completed to determine the key variables impacting indoor comfort and the durability of roof

  14. The Impact of Roof Pitch and Ceiling Insulation on Cooling Load of Naturally-Ventilated Attics

    Directory of Open Access Journals (Sweden)

    2012-07-01

    Full Text Available A 2D unsteady computational fluid dynamics (CFD model is employed to simulate buoyancy-driven turbulent ventilation in attics with different pitch values and ceiling insulation levels under summer conditions. The impacts of roof pitch and ceiling insulation on the cooling load of gable-roof residential buildings are investigated based on the simulation of turbulent air flow and natural convection heat transfer in attic spaces with roof pitches from 3/12 to 18/12 combined with ceiling insulation levels from R-1.2 to R-40. The modeling results show that the air flows in the attics are steady and exhibit a general streamline pattern that is qualitatively insensitive to the investigated variations of roof pitch and ceiling insulation. Furthermore, it is predicted that the ceiling insulation plays a control role on the attic cooling load and that an increase of roof pitch from 3/12 to 8/12 results in a decrease in the cooling load by around 9% in the investigated cases. The results suggest that the increase of roof pitch alone, without changing other design parameters, has limited impact on attics cooling load and airflow pattern. The research results also suggest both the predicted ventilating mass flow rate and attic cooling load can be satisfactorily correlated by simple relationships in terms of appropriately defined Rayleigh and Nusselt numbers.

    Heavy industrial activities such as mining, metal industry, coal fired power plants have produced large amount of by-products and wide-spread pollution, particularly in the period of centrally dictated economy after WWII, in Hungary. Several studies suggest that significant amount of these pollutants have been deposited in the urban environment. Nowadays, more than half of the world's population is living in urban areas and people spend almost 80% of their lives indoors in developed countries increasing human health risk due to contamination present in urban dwellings. Attic dust sampling was applied to determine the long-term airborne contamination load in the industrial town of Ajka (Hungary). There has been a high industrial activity in Ajka since the end of the 19th century. In addition to aluminum and alumina industry, coal mining, coal fired power plant and glass industry sites, generated numerous waste heaps which act as multi-contamination sources in the area. In October 2010 the Ajka red mud tailings pond failed and caused an accidental regional contamination of international significance. The major objective of this research was to study and map the spatial distribution of heavy metal contamination in airborne attic dust samples. At 27 sampling sites 30 attic dust samples were collected. Sampling strategy followed a grid-based stratified random sampling design. In each cell a house for attic dust sample collection was selected that was located the closest to a randomly generated point in the grid cell. The project area covers a 8x8 grid of 1x1 km cells with a total area of 64 km2. In order to represent long-term industrial pollution, houses with attics kept intact for at least 30-40 years were selected for sampling. Sampling included the collection of background samples remotely placed from the industrialized urban area.

    This project evaluates the cooling energy savings and cost effectiveness of radiation control retrofit strategies for residential attics in U.S. cooling-dominated climates. Usually, in residential applications, radiation control retrofit strategies are applied below the roof deck or on top of the attic floor insulation. They offer an alternative option to the addition of conventional bulk insulation such as fiberglass or cellulose insulation. Radiation control is a potentially low-cost energy efficiency retrofit strategy that does not require significant changes to existing homes. In this project, two groups of low-cost radiation control strategies were evaluated for southern U.S. applications. One uses a radiant barrier composed of two aluminum foils combined with an enclosed reflective air space and the second uses spray-applied interior radiation control coatings (IRCC).

    The focus of this study is on the performance of HPWHs with several different duct configurations and their effects on whole building heating, cooling, and moisture loads. A.O. Smith 60 gallon Voltex (PHPT-60) heat pump water heaters (HPWHs) were included at two project sites and ducted to or located within spray foamed encapsulated attics. The effect of ducting a HPWH's air stream does not diminish its efficiency if the ducting does not reduce intake air temperature, which expands HPWH application to confined areas. Exhaust ducts should be insulated to avoid condensation on the exterior, however this imposes a risk of condensation occurring in the duct's interior near the HPWH due to large variation of temperatures between the compressor and the duct and the presence of bulk moisture around the condenser. The HPWH's air conditioning impact on HVAC equipment loads is minimal when the intake and exhaust air streams are connected to a sealed attic and not the living space. A HPWH is not suitable as a replacement dehumidifier in sealed attics as peak moisture loads were observed to only be reduced if the heat pump operated during the morning. It appears that the intake air temperature and humidity was the most dominant variable affecting HPWH performance. Different ducting strategies such as exhaust duct only, intake duct only, and exhaust and intake ducting did not have any effect on HPWH performance.

    Highlights: • A novel integrated cool roof system for attic temperature reduction is introduced. • 13 °C temperature reduction achieved due to its efficient heat transfer mechanism. • Aluminium tube cavity of the roof is able to reduce the attic temperature. • This positive result is due to its efficient heat reflection and hot air rejection. • Thermal insulation coating incorporates the usage of eggshell waste as bio-filler. - Abstract: Cool roof systems play a significant role in enhancing the comfort level of occupants by reducing the attic temperature of the building. Heat transmission through the roof can be reduced by applying thermal insulation coating (TIC) on the roof and/or installing insulation under the roof of the attic. This paper focuses on a TIC integrated with a series of aluminium tubes that are installed on the underside of the metal roof. In this study, the recycled aluminium cans were arranged into tubes that act as a moving-air-cavity (MAC). The TIC was formulated using titanium dioxide pigment with chicken eggshell (CES) waste as bio-filler bound together by a polyurethane resin binder. The thermal conductivity of the thermal insulation paint was measured using KD2 Pro Thermal Properties Analyzer. Four types of cool roof systems were designed and the performances were evaluated. The experimental works were carried out indoors by using halogen light bulbs followed by comparison of the roof and attic temperatures. The temperature of the surrounding air during testing was approximately 27.5 °C. The cool roof that incorporated both TIC and MAC with opened attic inlet showed a significant improvement with a reduction of up to 13 °C (from 42.4 °C to 29.6 °C) in the attic temperature compared to the conventional roof system. The significant difference in the results is due to the low thermal conductivity of the thermal insulation paint (0.107 W/mK) as well as the usage of aluminium tubes in the roof cavity that was able to transfer

    Full Text Available The evaluation of daylight conditions in building interiors is based on the Daylight Factor concept after current Slovak standards. Criteria and requirements determined in these standards consider the worst daylight exterior conditions which are described by CIE overcast sky model. The sky luminance distribution of overcast sky is centrical to the zenith, so independence of window orientation to cardinal points is characteristic in daylighting calculations. The sky luminance distribution modelling is one of the main task of the daylight source research more than 50 years. It is evident that also other types of sky conditions exist in nature. An introduction of a new criterion based on photometric variables, which also consider sunlight influence, is expected. This article represents a study of the influence of the interior orientation on distribution of daylighting in attic spaces under an overcast and clear sky

    Residential retrofit is an essential element of any comprehensive strategy for improving residential energy efficiency, yet remains a challenging proposition to sell to homeowners due to low levels of awareness and lack of financial incentive. The Alliance for Residential Building Innovation (ARBI) implemented a project to increase residential retrofits in Davis, CA called Retrofit Your Attic developed and appropriate data sets were uploaded to the Building America Field Data Repository (BAFDR). Two key conclusions are a broad based public awareness campaign is needed to increase understanding of the makeup and benefits of residential retrofits and a dramatic shift is needed so that efficient homes are appraised and valued at higher levels. The SAVE Act, proposed bipartisan federal legislation [S.1106], offers one way to accomplish this.

    Full Text Available The present article deals with the Greek dialects in Old Attic Comedy. Aristophanes is the great­est representative of this genre and the one whose complete plays have been preserved. The works of his contemporary comic poets have survived in fragments. The author of this article analyses some dialectal features of comediographs such as Apol­lophanes, Crates, Eupolis, Epilycus, Strattis, Aris­tophanes. The fragments of Old Comedy are difficult to interpret because sometimes excerpts are badly battered, the dramatic context is missing, and we do not know who is speaking the fragmentary lines that have survived. The analysis of dialectal forms shows that Greek comediographs were interested in dialects. The representation of different dialects was customary in Old Attic Comedy. Comic writers used non-Attic dialects to make their personages more re­alistic or to make a mock of them. Many dialectal forms in comedies contain comicality, irony, parody, intertextuality or are paratragic and might be bor­rowed from a tragedy, lyric or epos. In the comedies Lysistrata and Acharnians, Aristophanes reproduces Laconian, Megarian, and Boiotian speeches. He had to pick out a convincing number of the most peculiar features present to these dialects to the audience. The phonologic and morphologic features of the dialectal words in comedies generally accord with epigraphic records.

    An experimental investigation was undertaken in which the thermal resistance for the heat flow through a typical timber framed pitched roofing system was measured under outdoor conditions for heat flow up. The measured thermal resistance of low resistance systems such as an uninsulated attic space and a reflective attic space compared well with published data. However, with higher thermal resistance systems containing bulk insulation within the timber frame, the measured result for a typical installation was as low as 50% of the thermal resistance determined considering two dimensional thermal bridging using the parallel path method. This result was attributed to three dimensional heat flow and insulation installation defects, resulting from the design and construction method used. Translating these results to a typical house with a 200 m{sup 2} floor area, the overall thermal resistance of the roof was at least 23% lower than the overall calculated thermal resistance including two dimensional thermal bridging. When a continuous layer of bulk insulation was applied to the roofing system, the measured values were in agreement with calculated resistances representing a more reliable solution. (author)

    The main aim of this article was to assess the atmospheric pollution with heavy metals due to copper mining Bučim near Radoviš, the Republic of Macedonia. The open pit and mine waste and flotation tailings are continually exposed to open air, which leads to winds carrying the fine particles into the atmosphere. Samples of attic dust were examined as historical archives of mine emissions, with the aim of elucidating the pathways of pollution. Dust was collected from the attics of 29 houses, built between 1920 and 1970. Nineteen elements (Ag, Al, As, Ba, Ca, Cd, Co, Cr, Cu, Li, Fe, K, Mg, Mn, Na, Ni, Pb, Sr, and Zn) were analyzed by atomic emission spectrometry with inductively coupled plasma. The obtained values of the investigated elements in attic dust samples were statistically processed using nonparametric and parametric analysis. Factor analysis revealed three factors governing the source of individual chemical elements. Two of them grouping Ca, Li, Mg, Mn, and Sr (Factor 1) and Co, Cr, and Ni (Factor 2) can be characterized as geogenic. The third factor grouping As, Cu, and Pb is anthropogenic and mirrors dust fallout from mining operation and from flotation tailings. Maps of areal deposition were prepared for this group of elements, from which correlation of these anthropogenic born elements was confirmed.

    Full Text Available The group of 410 attic pots from Cancho Roano palace-sanctuary (Zalamea de la Serena, Badajoz is considered one of the most important collections of the 5th century BC ever published in the Iberian Peninsula. With 360 examples, the best represented pots are those belonging to the stemless inset-lip type. They show a wide variety in typology and macroscopical features, which suggests the existence of materials from different production centres. Because of this, an archaeometric study by means of X-Ray Fluorescence and X-Ray Diffraction analyses has been conducted in order to investigate their provenance and technology. The characterised material, which includes 60 examples, is the biggest one ever published for the 5th century BC in the Mediterranean basin. The results suggest an Attic origin, while the important differences in their macroscopic and typological features are due to technological factors.

    El conjunto de piezas áticas del palacio-santuario de Cancho Roano (Zalamea de la Serena, Badajoz, con 410 individuos, es uno de los más importantes publicados hasta el presente en la Península Ibérica para el siglo V a.C. Destaca, con 360 piezas, la Copa Cástulo que ofrece una gran variedad morfológica y de características macroscópicas que permiten plantear la hipótesis de la existencia de materiales procedentes de diferentes centros productores. Para contrastar esta posibilidad se ha realizado un estudio arqueométrico por Fluorescencia de Rayos X y Difracción de Rayos X encaminado a la determinación de procedencia de los materiales, así como al estudio de su tecnología de producción. El conjunto caracterizado, con 60 individuos, es el más importante nunca publicado para esta cronología de siglo V a.C. en todo el Mediterráneo. Los resultados sugieren un origen ático, mientras que las grandes diferencias macroscópicas y tipológicas se deben a factores tecnológicos.

    Attic dusts were examined as historical archives of anthropogenic emissions, with the goal of elucidating the enrichment pathways associated with hydrothermal exploitation of Cu, Pb, and Zn minerals in the Bregalnica River basin in the eastern part of the Republic of Macedonia. Dust samples were collected from 84 settlements. Atomic emission spectrometry and mass spectrometry with inductively coupled plasma were applied as analytical techniques for the determination of 69 element contents. Multivariate analysis was applied for the extraction of dominant geochemical markers. The lithogenic distribution was simplified to six dominant geochemical markers: F1: Ga-Nb-Ta-Y-(La-Gd)-(Eu-Lu); F2: Be-Cr-Li-Mg-Ni; F3: Ag-Bi-Cd-Cu-In-Mn-Pb-Sb-Te-W-Zn; F4: Ba-Cs-Hf-Pd-Rb-Sr-Tl-Zr; F5: As-Co-Ge-V; and F6: К-Na-Sc-Ti. The anthropogenic effects on the air pollution were marked by a dominance of F3 and secondary dominance of F5. The fifth factor also was determined as a lithogenic marker for the occurrence of the very old Rifeous shales. The first factor also presents a very unique association that despite the heterogeneity relays on natural phenomena of tracking the deposition in areas of Proterosoic gneisses; related to the distribution of fine particles was associated with carbonate-silicate volcanic rocks. Intensive poly-metallic dust depositions were recorded only in the surroundings of localities where the hydrothermal extractions are implemented. Long-term deposition can be considered as pollution indexes for these hot spots. This mainly affects the Cd, Pb, and Zn deposition that is as high as 25, 3900, and 3200 mg/kg, respectively.

    The focus of this study is on the performance of HPWHs with several different duct configurations and their effects on whole building heating, cooling, and moisture loads. A.O. Smith 60 gallon Voltex (PHPT-60) heat pump water heaters (HPWHs) were included at two project sites and ducted to or located within spray foamed encapsulated attics. The effect of ducting a HPWH's air stream does not diminish its efficiency if the ducting does not reduce intake air temperature, which expands HPWH application to confined areas. Exhaust ducts should be insulated to avoid condensation on the exterior, however this imposes a risk of condensation occurring in the duct's interior near the HPWH due to large variation of temperatures between the compressor and the duct and the presence of bulk moisture around the condenser. The HPWH's air conditioning impact on HVAC equipment loads is minimal when the intake and exhaust air streams are connected to a sealed attic and not the living space. A HPWH is not suitable as a replacement dehumidifier in sealed attics as peak moisture loads were observed to only be reduced if the heat pump operated during the morning. It appears that the intake air temperature and humidity was the most dominant variable affecting HPWH performance. Different ducting strategies such as exhaust duct only, intake duct only, and exhaust and intake ducting did not have any effect on HPWH performance.

    In the former German Democratic Republic (GDR) the wood preservative Hylotox 59, which contained DDT and lindane as biocides, was used indoors until 1988. It was the aim of this study to determine the concentration levels of DDT and lindane in the air of attics, newly converted attic apartments or apartments situated immediately under attics which had been treated with Hylotox 59. In some cases dust and wood samples were examined, too. This study shows that concentrations of DDT and lindane of up to 4600 and 930 ng/m{sup 3} can be found in air of treated attics even more than 20 years after the application of wood preservatives. However, the median concentrations in recently converted attic apartments and apartments below an attic were much lower, namely 20 and 40 ng/m{sup 3}, respectively, for DDT and 5 and 20 ng/m{sup 3}, respectively, for lindane. Only some apartments showed DDT and lindane concentrations above 100 ng/m{sup 3}. In these cases biocides had been used directly in the apartment or there was a possibility for an air exchange between the attic and the rooms. Exposure of dwellers to DDT and lindane occurs mainly by inhalation. In addition, infants and small children who usually play on the floor may be exposed by contact with and intake of house dust. The maximum DDT content of house dust observed in the apartments under study was 200 mg/kg, with a median of 20 mg/kg. The lindane content of house dust reached only 9 mg/kg. The calculated exposure of a small child to DDT and lindane in house dust is far below the allowable daily intake (ADI) recommended by FAO/WHO. (orig.)

    Described in this paper is an air duct heat collecting system, forming a link in the chain of natural energy utilization, in an attic of a house actually in presence. When a sirocco fan (blowing air from an indoor induction duct into the room) at the base of the highblocked floor is turned, air is sucked through an air intake under the eaves into a heat collecting duct (constructed utilizing the tilt roof and rafter). Heat from the roof warmed by sunshine is absorbed by air in the heat collecting duct and is fed to the highblocked floor structure through a heat collecting room and the induction duct. This system functions quite effectively as a ventilating device. Dew condensation on the walls and floor and musty smell have been eliminated. This system is good enough as a heater even on chilly days in early spring when there is sunshine. In the time zone with the sun shining, the system collects 4{times}10{sup 4}kJ per day, exhibiting a heat collecting efficiency of 4%. The heat collecting duct was analyzed for thermal environment, and the heat flux of the collected heat was determined as Qk(W/m{sup 2}=0.1{times}I-1.3{Theta}d-{Theta}a). In this equation, I is the quantity of insolation (W/m{sup 2}), {Theta}d is the temperature in the heat collecting duct, and {Theta}a is the free air temperature. 2 refs., 8 figs.

    This paper reports a duct heat collecting system installed in the ECOLO-HOUSE for snow countries. This system is an air heat collecting system of the outside air introducing type utilizing as a solar heat collector the single pitch roof often seen in snow countries. Outside air is introduced from below eaves into a heat collecting duct made by nailing plywoods onto rafters from the attic side to collect heat on the roof. Operating a sirocco fan connected to the induction duct located on the high-floor foundation sucks outside air from an air intake opening under the eaves into the heat collecting duct. Air which has absorbed heat on the roof and been warmed in the heat collecting duct by insolation goes into a heat collecting chamber. The air is sent into the high-floor foundation through the induction duct laid from the heat collecting chamber. Air is exchanged 8.7 times by the fan when it is operated all day continuously. Condensation in the fuel chamber floor and walls during the rainy season has disappeared, and so has odor at the same time. As a result of the humidity measurement, a location into which warm air is sent has difference in humidity as great as 15% from a location where no warm air is sent. 2 refs., 6 figs., 2 tabs.

    Objectives The objectives of the study were to (1) study the anatomical variations of the tensor fold and its anatomic relation with transverse crest, supratubal recess, and anterior epitympanic space and (2) explore the most appropriate endoscopic surgical approach to each type of the tensor fold variants. Study Design Cadaver dissection study. Setting Temporal bone dissection laboratory. Subjects and Methods Twenty-eight human temporal bones (26 preserved and 2 fresh) were dissected through an endoscopic transcanal approach between September 2016 and June 2017. The anatomical variations of the tensor fold, transverse crest, supratubal recess, and anterior epitympanic space were studied before and after removing ossicles. Results Three different tensor fold orientations were observed: vertical (type A, 11/28, 39.3%) with attachment to the transverse crest, oblique (type B, 13/28, 46.4%) with attachment to the anterior tegmen tympani, and horizontal (type C, 4/28, 14.3%) with attachment to the tensor tympani canal. The tensor fold was a complete membrane in 20 of 28 (71.4%) specimens, preventing direct ventilation between the supratubal recess and anterior epitympanic space. We identified 3 surgical endoscopic approaches, which allowed visualization of the tensor fold without removing the ossicles. Conclusions The orientation of the tensor fold is the determining structure that dictates the conformation and limits of the epitympanic space. We propose a classification of the tensor fold based on 3 anatomical variants. We also describe 3 different minimally invasive endoscopic approaches to identify the orientation of the tensor fold while maintaining ossicular chain continuity.

    Full Text Available Background: References to neurologic disorders are frequently found in fictional literature and may precede description in the medical literature. Aim: Our aim was to compare Charlotte Brontë’s depiction of Bertha Mason in Jane Eyre to the tenets set forth in George Huntington’s original essay “On chorea” with the hypothesis that Mason was displaying features of Huntington disease. Results: Charlotte Brontë’s 1847 Victorian novel Jane Eyre features the character Bertha Mason, who is portrayed with a progressive psychiatric illness, violent movements, and possible cognitive decline. Similar to Huntington’s tenets, Mason has a disorder with a strong family history suggestive of autosomal dominant inheritance with onset in adulthood, and culminating in suicide. Conclusion: Brontë’s character had features of Huntington disease as originally described by Huntington. Brontë’s keen characterization may have increased awareness of treatment of neuropsychiatric patients in the Victorian era.

    Full Text Available The paper offers a brief outline of the general characteristics of the Socratesʼ comic portrayal. It is argued, that Aristophanesʼ portrait of Socrates is based on earlier writings and that there is a certain unity of all preserved comic portraits of Socrates. This unity is linguistically analysed and further characterised as a peculiar merging of physiological and mystical features, which can be found also in the philosophical sects of the southern Italy. The conclusion is that Socrates was in these comedies portrayed as pythagorizing mystic.

    A new generation of full variable-capacity air-conditioning (A/C) and heat pump units has come on the market that promises to deliver very high cooling and heating efficiency. The units are controlled differently than standard single-capacity (fixed-capacity) systems. Instead of cycling on at full capacity and cycling off when the thermostat is satisfied, the new units can vary their capacity over a wide range (approximately 40%–118% of nominal full capacity) and stay on for 60%–100% more hours per day than the fixed-capacity systems depending on load-to-capacity ratios. Two-stage systems were not evaluated in this research effort.

    A new generation of central, ducted variable-capacity heat pump systems has come on the market, promising very high cooling and heating efficiency. They are controlled differently than standard fixed-capacity systems. Instead of cycling on at full capacity and then cycling off when the thermostat is satisfied, they vary their cooling and heating output over a wide range (approximately 40% - 118% of nominal full capacity), thus staying 'on' for 60% - 100% more hours per day compared to fixed -capacity systems. Experiments in this research examined the performance of 2-ton and 3-ton fixed- and variable-capacity systems and the impacts of system oversizing.

    In this literature review and analysis, we focus on the thermal, moisture and energy performance of sealed and insulated attics in California climates. Thermal. Sealed and insulated attics are expected to maintain attic air temperatures that are similar to those in the house within +/- 10°F. Thermal stress on the assembly, namely high shingle and sheathing temperatures, are of minimal concern. In the past, many sealed and insulated attics were constructed with insufficient insulation levels (~R-20) and with too much air leakage to outside, leading to poor thermal performance. To ensure high performance, sealed and insulated attics in new California homes should be insulated at levels at least equivalent to the flat ceiling requirements in the code, and attic envelopes and ducts should be airtight. We expect that duct systems in well-constructed sealed and insulated attics should have less than 2% HVAC system leakage to outside. Moisture. Moisture risk in sealed and insulated California attics will increase with colder climate regions and more humid outside air in marine zones. Risk is considered low in the hot-dry, highly populated regions of the state, where most new home construction occurs. Indoor humidity levels should be controlled by following code requirements for continuous whole-house ventilation and local exhaust. Pending development of further guidance, we recommend that the air impermeable insulation requirements of the International Residential Code (2012) be used, as they vary with IECC climate region and roof finish. Energy. Sealed and insulated attics provide energy benefits only if HVAC equipment is located in the attic volume, and the benefits depend strongly on the insulation and airtightness of the attic and ducts. Existing homes with leaky, uninsulated ducts in the attic should have major savings. When compared with modern, airtight duct systems in a vented attic, sealed and insulated attics in California may still provide substantial benefit

    This report provides results from a second-phase research study of a phenomenon generally referred to as wind washing. Wind washing is the movement of unconditioned air around or through building thermal barriers in such a way as to diminish or nullify the intended thermal performance. In some cases, thermal and air barriers are installed very poorly or not at all, and air can readily move from unconditioned attic spaces into quasi-conditioned interstitial spaces. This study focused on the impact of poorly sealed and insulated floor cavities adjacent to attic spaces in Florida homes. In these cases, unconditioned attic air can be transferred into floor cavities through pathways driven by natural factors such as wind, or by thermal differences between the floor cavity and the attic. Air can also be driven into a floor cavity through mechanical forces imposed by return duct leakage in the floor cavity.

    This article presents various metal roof configurations that were tested at Oak Ridge National Laboratory in Tennessee, U.S.A. between 2009 and 2013, and describes their potential for reducing the attic-generated space conditioning loads. These roofs contained different combinations of phase change material, rigid insulation, low emittance surface and above-sheathing ventilation, with standing-seam metal panels on top. These roofs were designed to be installed on existing roofs decks, or on top of asphalt shingles for retrofit construction. All the tested roofs showed the potential for substantial energy savings compared to an asphalt shingle roof, which was used as a control for comparison. The roofs were constructed on a series of adjacent attics separated at the gables using thick foam insulation. The attics were built on top of a conditioned room. All attics were vented at the soffit and ridge. The test roofs and attics were instrumented with an array of thermocouples. Heat flux transducers were installed in the roof deck and attic floor (ceiling) to measure the heat flows through the roof and between the attic and conditioned space below. Temperature and heat flux data were collected during the heating, cooling and swing seasons over a 3 year period. Data from previous years of testing have been published. Here, data from the latest roof configurations being tested in year 3 of the project are presented. All test roofs were highly effective in reducing the heat flows through the roof and ceiling, and in reducing the diurnal attic temperature fluctuations.

    Typically, the cheapest way to install a central air conditioning system in residential buildings is to place the ductwork in the attic. Energy losses due to duct-attic interactions can be great, but current whole-house models are unable to capture the dynamic multi-mode physics of the interactions. The building industry is notoriously fragmented and unable to devote adequate research resources to solve this problem. Builders are going to continue to put ducts in the attic because floor space is too expensive to closet them within living space, and there are both construction and aesthetic issues with other approaches such as dropped ceilings. Thus, there is a substantial need to publicly document duct losses and the cost of energy used by ducts in attics so that practitioners, builders, homeowners and state and federal code officials can make informed decisions leading to changes in new construction and additional retrofit actions. Thus, the goal of this study is to conduct a comparison of AtticSim and EnergyPlus simulation algorithms to identify specific features for potential inclusion in EnergyPlus that would allow higher-fidelity modeling of HVAC operation and duct transport of conditioned air. It is anticipated that the resulting analysis from these simulation tools will inform energy decisions relating to the role of ducts in future building energy codes and standards.

    We report a rare case of incus dislocation to the external auditory canal after a mountain-biking accident. Otoscopy showed ossicular protrusion in the upper part of the left external auditory canal. CT indicated the disappearance of the incus, and an incus-like bone was found in the left external auditory canal. There was another bony and board-like structure in the attic. During the surgery, a square-shaped bony plate (1 x 1 cm) was found in the attic. It was determined that the bony plate had fallen from the tegmen of the attic. The fracture line in the posterosuperior auditory canal extending to the fossa incudis was identified. According to these findings, it was considered that the incus was pushed into the external auditory canal by the impact of skull injury through the fractured posterosuperior auditory canal, which opened widely enough for incus dislocation.

    Cholesteatomas are thought to result from ingrowth of keratinizing squamous epithelium from external ear to middle ear. The cholesteatomas are usually diagnosed by clinical symptoms and signs, otoscopy, and plain radiograms. But various view points are emphasized radiologically before operation, leading to examine by computed tomography (CT), especially in complicated cases. We retrospectively reviewed the CT findings of cholesteatomas in 25 surgically proven cases during the period from May, 1983 to Aug, 1988. The results were as follows: 1. Most cholesteatomas showed soft tissue mass and bony erosion of ossicles (88%), attic wall and mastoid antrum (84%) on temporal bone CT scan. 2. The CT members of cholesteatomas ranged from 25 to 50 HU (avg. 33 HU). 3. Involved sites were attic (16%), antrum (28%), and both attic and antrum (56%). Other sites were middle ear cavity and external auditory canal. 4. Extra-tympanomastoid extension of cholesteatoma was intracranial abscess (8%), exposure of dural sinus (8%), and extension along with neck (4%)

    California s major energy utilities and the California Energy Commission (CEC) are seeking to allocate capital that yields the greatest return on investment for energy infrastructure that meets any part of the need for reliable supplies of energy. The utilities are keenly interested in knowing the amount of electrical energy savings that would occur if cool roof color materials are adopted in the building market. To meet this need the Oak Ridge National Laboratory and the Lawrence Berkeley National Laboratory (LBNL) have been collaborating on a Public Interest Energy Research (PIER) project to develop an industry-consensus energy-savings calculator. The task was coordinated with an ongoing effort supported by the DOE to develop one calculator to achieve both the DOE and the EPA objectives for deployment of cool roof products. Recent emphasis on domestic building energy use has made the work a top priority by the Department of Energy s (DOE) Building Technologies Program. The Roof Savings Calculator (RSC) tool is designed to help building owners, manufacturers, distributors, contractors and practitioners easily run complex simulations. The latest web technologies and usability design were employed to provide an easy input interface to an annual simulation of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim. Building defaults were assigned based on the best available statistical evidence and can provide energy and cost savings after the user selects nothing more than the building location. A key goal for the tool is to promote the energy benefits of cool color tile, metal and asphalt shingle roof products and other energy saving systems. The RSC tool focuses on applications for the roof and attic; however, the code conducts a whole building simulation that puts the energy and heat flows of the roof and attic into the perspective of the whole house. An annual simulation runs in about 30 sec. In addition to cool

    Totally endoscopic ear surgery is a relatively new method for managing chronic ear disease. This study aimed to test the null hypothesis that open and endoscopic approaches have similar direct costs for the management of attic cholesteatoma, from an Australian private hospital setting. A retrospective direct cost comparison of totally endoscopic ear surgery and traditional canal wall up mastoidectomy for the management of attic cholesteatoma in a private tertiary setting was undertaken. Indirect and future costs were excluded. A direct cost comparison of anaesthetic setup and resources, operative setup and resources, and surgical time was performed between the two techniques. Totally endoscopic ear surgery has a mean direct cost reduction of AUD$2978.89 per operation from the hospital perspective, when compared to canal wall up mastoidectomy. Totally endoscopic ear surgery is more cost-effective, from an Australian private hospital perspective, than canal wall up mastoidectomy for attic cholesteatoma.

    A web-based Roof Savings Calculator (RSC) has been deployed for the United States Department of Energy as an industry-consensus tool to help building owners, manufacturers, distributors, contractors and researchers easily run complex roof and attic simulations. This tool employs modern web technologies, usability design, and national average defaults as an interface to annual simulations of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim in order to provide estimated annual energy and cost savings. In addition to cool reflective roofs, RSC simulates multiple roof and attic configurations including different roof slopes, above sheathing ventilation, radiant barriers, low-emittance roof surfaces, duct location, duct leakage rates, multiple substrate types, and insulation levels. A base case and energy-efficient alternative can be compared side-by-side to estimate monthly energy. RSC was benchmarked against field data from demonstration homes in Ft. Irwin, California; while cooling savings were similar, heating penalty varied significantly across different simulation engines. RSC results reduce cool roofing cost-effectiveness thus mitigating expected economic incentives for this countermeasure to the urban heat island effect. This paper consolidates comparison of RSC s projected energy savings to other simulation engines including DOE-2.1E, AtticSim, Micropas, and EnergyPlus, and presents preliminary analyses. RSC s algorithms for capturing radiant heat transfer and duct interaction in the attic assembly are considered major contributing factors to increased cooling savings and heating penalties. Comparison to previous simulation-based studies, analysis on the force multiplier of RSC cooling savings and heating penalties, the role of radiative heat exchange in an attic assembly, and changes made for increased accuracy of the duct model are included.

    Thermal resistances have been measured for attic spaces insulated with reflective insulations. Three test units located in Malaysia were instrumented to provide heat flux and temperatures for the calculation of time-average RSI-values (RSI is representing R-value in SI units). The RSI for attics with enclosed reflective air spaces were in the range 2-3 m2·K/W while the uninsulated attics averaged about 0.4 m2·K/W. The RSI-values determined in this project were for heat-flow down, the predominant heat-flow direction for attic spaces in Equatorial regions. The observed thermal resistances due to the installation of the reflective insulation results in an 80-90% annual decrease in the heat transfer across the ceiling. This reduces utility usage for air conditioned units and improved comfort for occupants. The research demonstrates the use of transient data for the determination of thermal insulation performance and usefulness of enclosed reflective air spaces for thermal resistance.

    With U.S. Department of Energy goals of reducing existing home energy use by 30% and new home energy use by 50%, it is imperative to focus on several energy efficiency measures, including the quality of air and thermal barriers. This report provides results from a second-phase research study of a phenomenon generally referred to as wind washing. Wind washing is the movement of unconditioned air around or through building thermal barriers in such a way as to diminish or nullify the intended thermal performance. In some cases, thermal and air barriers are installed very poorly or not at all, and air can readily move from unconditioned attic spaces into quasi-conditioned interstitial spaces. This study focused on the impact of poorly sealed and insulated floor cavities adjacent to attic spaces in Florida homes. In these cases, unconditioned attic air can be transferred into floor cavities through pathways driven by natural factors such as wind, or by thermal differences between the floor cavity and the attic. Air can also be driven into a floor cavity through mechanical forces imposed by return duct leakage in the floor cavity.

    The Roof Savings Calculator (RSC) was developed through collaborations among Oak Ridge National Laboratory (ORNL), White Box Technologies, Lawrence Berkeley National Laboratory (LBNL), and the Environmental Protection Agency in the context of a California Energy Commission Public Interest Energy Research project to make cool-color roofing materials a market reality. The RSC website and a simulation engine validated against demonstration homes were developed to replace the liberal DOE Cool Roof Calculator and the conservative EPA Energy Star Roofing Calculator, which reported different roof savings estimates. A preliminary analysis arrived at a tentative explanation for why RSC results differed from previous LBNL studies and provided guidance for future analysis in the comparison of four simulation programs (doe2attic, DOE-2.1E, EnergyPlus, and MicroPas), including heat exchange between the attic surfaces (principally the roof and ceiling) and the resulting heat flows through the ceiling to the building below. The results were consolidated in an ORNL technical report, ORNL/TM-2013/501. This report is an in-depth inter-comparison of four programs with detailed measured data from an experimental facility operated by ORNL in South Carolina in which different segments of the attic had different roof and attic systems.

    2002-01-01

    The proposed ASHRAE Standard 152P ''Method of Test for Determining the Design and Seasonal Efficiencies of Residential Thermal Distribution Systems'' (ASHRAE 2002) has recently completed its second public review. As part of the standard development process, this study compares the forced air distribution system ratings provided by the public review draft of Standard 152P to measured field results. 58 field tests were performed on cooling systems in 11 homes in the summers of 1998 and 1999. Seven of these houses had standard attics with insulation on the attic floor and a well-vented attic space. The other four houses had unvented attics where the insulation is placed directly under the roof deck and the attic space is not deliberately vented. Each house was tested under a range of summer weather conditions at each particular site, and in some cases the amount of duct leakage was intentionally varied. The comparison between 152P predicted efficiencies and the measured results includes evaluation of the effects of weather, duct location, thermal conditions, duct leakage, and system capacity. The results showed that the difference between measured delivery effectiveness and that calculated using proposed Standard 152P is about 5 percentage points if weather data, duct leakage and air handler flow are well known. However, the accuracy of the standard is strongly dependent on having good measurements of duct leakage and system airflow. Given that the uncertainty in the measured delivery effectiveness is typically also about 5 percentage points, the Standard 152P results are acceptably close to the measured data

    The paper focuses on Swedish homeowners' need for and perceptions about adopting building envelop energy efficiency measures. The results of a questionnaire surveying of 3000 randomly selected homeowners during the summer of 2008 showed that 70-90% of the respondents had no intention of adopting such a measure over the next 10 years. The main reasons for non-adoption were that homeowners were satisfied with the physical condition, thermal performance, and aesthetics of their existing building envelope components. A greater proportion of respondents perceived that improved attic insulation has more advantages than energy efficient windows and improved wall insulation, but windows were more likely to be installed than improved attic insulation. Respondents gave high priority to economic factors in deciding on an energy efficiency measure. Hence, economic incentives could be used to increase the adoption of such measures. Interpersonal sources, construction companies, installers, and energy advisers were important sources of information for homeowners as they planned to adopt energy efficiency measures

    High resolution computed tomography was performed in 57 cases with various middle ear diseases (chronic otitis media, otitis media with effusion, acute otitis media and atelectasis). Although further improvement in detectability is necessary in order to discriminate each type of the soft tissue lesions, CT is the most useful method currently available in detecting the small structures and soft tissue lesions of the middle ear. In particular, the lesions at the tympanic isthmus and tympanic fold could very clearly be detected only by CT. In acute otitis media, lesions usually started in the attic and spread to the mastoid air cells. In otitis media with effusion, the soft tissue shadow was ovserved in the attic and mastoid air cell. CT is valuable in diagnosis, evaluation of the treatment and prognosis, and analysis of pathophysiology in the middle ear diseases. (author)

    Full Text Available The article dwells upon the reconstruction technologies of the residential buildings of the series that are not subjected to demolishing by way of superstructing of the attic floors and standard floors made of unitized folding units, adding of lifts, unitized elements of kitchens, living rooms and loggias. Their application makes it possible to increase the areas of kitchens by 6.0…8.2 m2, of bedrooms and other premises - by 3.5−4.2 m2. The technology of the attic units manufacture under plant conditions has been worked out. It has made it possible to optimize the design concept of the articulated joints, ensuring the transport adaptability due to flatwork elements folding. The technologies of the high-speed superstructing and building up of the buildings, using line production of works have been investigated.

    Carbon and oxygen isotope analyses have been used to test the provenance of the marble of some Attic sarcophagi in the British Museum collection. Of three believed to be of Pentelic marble, only one has been so confirmed. Analyses of fragmentary sarcophagi of similar workmanship has confirmed their Proconnesian origin. Data from fragments of Sidamara sarcophagi have supplemented observations of technique, finish and dimensions of carved figures and decoration to determine whether the fragments come from the same sarcophagus.

    2010-07-01

    For low-rise buildings in equatorial region, the roof is exposed to solar radiation longer than other parts of the envelope. Roofs are to be designed to reject heat and moderate the thermal impact. These are determined by the design and construction of the roofing system. The pitch of roof and the properties of construction affect the heat gain into the attic and subsequently the indoor temperature of the living spaces underneath. This finally influences the thermal comfort conditions of naturally ventilated buildings and cooling load of conditioned buildings. This study investigated the effect of insulated sloping roof on thermal energy performance of the building. A whole-building thermal energy computer simulation tool, Integrated Environmental Solution (IES), was used for the modelling and analyses. A building model with dimension of 4.0 m × 4.0 m × 3.0 m was designed with insulated roof and conventional construction for other parts of the envelope. A 75 mm conductive insulation material with thermal conductivity (k-value) of 0.034 Wm-1K-1 was installed underneath the roof tiles. The building was modelled with roof pitch angles of 0° , 15°, 30°, 45°, 60° and simulated for the month of August in Malaysian climate conditions. The profile for attic temperature, indoor temperature and cooling load were downloaded and evaluated. The optimum roof pitch angle for best thermal performance and energy saving was identified. The results show the pitch angle of 0° is able to mitigate the thermal impact to provide the best thermal condition with optimum energy savings. The maximum temperature difference between insulated and non-insulted roof for attic (AtticA-B) and indoor condition (IndoorA-B) is +7.8 °C and 0.4 °C respectively with an average energy monthly savings of 3.9 %.

  17. Quantitative analysis of cholesteatoma using high resolution computed tomography

    1992-01-01

    Seventy-three cases of adult cholesteatoma, including 52 cases of pars flaccida type cholesteatoma and 21 of pars tensa type cholesteatoma, were examined using high resolution computed tomography, in both axial (lateral semicircular canal plane) and coronal sections (cochlear, vestibular and antral plane). These cases were classified into two subtypes according to the presence of extension of cholesteatoma into the antrum. Sixty cases of chronic otitis media with central perforation (COM) were also examined as controls. Various locations of the middle ear cavity were measured in terms of size in comparison with pars flaccida type cholesteatoma, pars tensa type cholesteatoma and COM. The width of the attic was significantly larger in both pars flaccida type and pars tensa type cholesteatoma than in COM. With pars flaccida type cholesteatoma there was a significantly larger distance between the malleus and lateral wall of the attic than with COM. In contrast, the distance between the malleus and medial wall of the attic was significantly larger with pars tensa type cholesteatoma than with COM. With cholesteatoma extending into the antrum, regardless of the type of cholesteatoma, there were significantly larger distances than with COM at the following sites: the width and height of the aditus ad antrum, and the width, height and anterior-posterior diameter of the antrum. However, these distances were not significantly different between cholesteatoma without extension into the antrum and COM. The hitherto demonstrated qualitative impressions of bone destruction in cholesteatoma were quantitatively verified in detail using high resolution computed tomography. (author)

    A web-based Roof Savings Calculator (RSC) has been deployed for the Department of Energy as an industry-consensus tool to help building owners, manufacturers, distributors, contractors and researchers easily run complex roof and attic simulations. This tool employs the latest web technologies and usability design to provide an easy input interface to an annual simulation of hour-by-hour, whole-building performance using the world-class simulation tools DOE-2.1E and AtticSim. Building defaults were assigned based on national averages and can provide estimated annual energy and cost savings after the user selects nothing more than building location. In addition to cool reflective roofs, the RSC tool can simulate multiple roof and attic configurations including different roof slopes, above sheathing ventilation, radiant barriers, low-emittance surfaces, HVAC duct location, duct leakage rates, multiple layers of building materials, ceiling and deck insulation levels, and other parameters. A base case and energy-efficient alternative can be compared side-by-side to generate an energy/cost savings estimate between two buildings. The RSC tool was benchmarked against field data for demonstration homes in Ft. Irwin, CA. However, RSC gives different energy savings estimates than previous cool roof simulation tools so more thorough software and empirical validation proved necessary. This report consolidates much of the preliminary analysis for comparison of RSC s projected energy savings to that from other simulation engines.

    2014-03-01

    BSC worked directly with the David Weekley Homes - Houston division to redesign three floor plans in order to locate the HVAC system in conditioned space. The purpose of this project is to develop a cost effective design for moving the HVAC system into conditioned space. In addition, BSC conducted energy analysis to calculate the most economical strategy for increasing the energy performance of future production houses. This is in preparation for the upcoming code changes in 2015. The builder wishes to develop an upgrade package that will allow for a seamless transition to the new code mandate. The following research questions were addressed by this research project: 1. What is the most cost effective, best performing and most easily replicable method of locating ducts inside conditioned space for a hot-humid production home builder that constructs one and two story single family detached residences? 2. What is a cost effective and practical method of achieving 50% source energy savings vs. the 2006 International Energy Conservation Code for a hot-humid production builder? 3. How accurate are the pre-construction whole house cost estimates compared to confirmed post construction actual cost? BSC and the builder developed a duct design strategy that employs a system of dropped ceilings and attic coffers for moving the ductwork from the vented attic to conditioned space. The furnace has been moved to either a mechanical closet in the conditioned living space or a coffered space in the attic.

    Moore, D.

    1981-03-01

    An instrumented single family residence in Greenville, South Carolina, has approximately 1086 square feet on conditioned space. Solar energy is used for space heating the home and preheating domestic and water (DHW). Solar energy enters the attic through a 416 square foot aperture which is double glazed with corrugated, translucent, fiberglass reinforced, acrylic panels. Warm air accumulates in the peak of the attic roof and circulates through the conditioned space or through storage by an air handler. Solar energy is stored in an 870 cubic foot storage bin containing 85,460 pounds of crushed rock located under the house. cold water is preheated in the attic by thermosiphoning water from the 80 gallon preheat tank through a manifold system of copper tubes. These tubes are attached to black sheet metal plates. Preheated city water is stored in the preheat tank and supplied, on demand, to a conventional 80 gallon DHW tank. When solar energy is insufficient to satisfy the space heating load, a water to air heat exchanger in the hot air supply duct provides auxiliary energy for space heating. A gas fired water heater provides auxiliary energy for the water to air heat exchanger and the DHW.

The article touches upon the questions linked to the role of rhetorical theory and techniques reinforced by the Greek educational system and the Byzantine Atticism. Particular attention is paid to the different written registers – low, middle, and high –, different styles according to genre and period, and the lack of consistency in writing at all levels.

    This measure guideline covers how to assess and carry out the isolation of natural draft combustion appliances from the conditioned space of low-rise residential buildings. It deals with combustion appliances located either within the living space in enclosed closets or side rooms or outside the living space in an adjacent area like an attic or garage. This subset of houses does not require comprehensive combustion safety tests and simplified prescriptive procedures can be used to address safety concerns. This allows residential energy retrofit contractors inexperienced in advanced combustion safety testing to effectively address combustion safety issues and allow energy retrofits including tightening and changes to distribution and ventilation systems to proceed.

    Science.gov (United States)

    1980-01-01

    Fire retardant cellulose insulation is produced by shredding old newspapers and treating them with a combination of chemicals. Insulating material is blown into walls and attics to form a fiber layer which blocks the flow of air. All-Weather Insulation's founders asked NASA/UK-TAP to help. They wanted to know what chemicals added to newspaper would produce an insulating material capable of meeting federal specifications. TAP researched the query and furnished extensive information. The information contributed to successful development of the product and helped launch a small business enterprise which is now growing rapidly.

    2010-07-15

    The paper focuses on Swedish homeowners' need for and perceptions about adopting building envelop energy efficiency measures. The paper is based on a questionnaire survey of 3059 homeowners (response rate of 36%) selected by stratified random sampling during the summer of 2008. The results showed that 70-90% of the respondents had no intention of adopting such a measure over the next 10 years. The main reasons for non-adoption were that homeowners were satisfied with the physical condition, thermal performance, and aesthetics of their existing building envelope components. A greater proportion of respondents perceived that improved attic insulation has more advantages than energy efficient windows and improved wall insulation, but windows were more likely to be installed than improved attic insulation. Respondents gave high priority to economic factors in deciding on an energy efficiency measure. Interpersonal sources, construction companies, installers, and energy advisers were important sources of information for homeowners as they planned to adopt building envelope energy efficiency measures. Policy measures to facilitate the rate of adoption of energy efficient building envelope measures are discussed.

    1977-03-01

    Twenty-two female big brown bats (Eptesicus fuscus) were collected in a house attic in Montgomery County, Maryland. Seventeen were fed mealworms (Tenebrio molitor larvae) that contained 166 ppM DDE; the other five were fed uncontaminated mealworms. After 54 days of feeding, six dosed bats were frozen and the remaining 16 were starved to death. In a second experiment, 21 female big brown bats were collected in a house attic in Prince Georges County, Maryland. Sixteen were fed mealworms that contained 9.4 ppM Aroclor 1254 (PCB). After 37 days, two bats had died, four dosed bats were frozen, and the remaining 15 were starved to death. Starvation caused mobilization of stored residues. After the feeding periods, average weights of all four groups (DDE-dosed, DDE control, PCB-dosed, PCB control) had increased. However, weights of DDE-dosed bats had increased significantly more than those of their controls, whereas weights of PCB-dosed bats had increased significantly less than those of their controls. During starvation, PCB-dosed bats lost weight significantly more slowly than controls. Because PCB levels in dosed bats resembled levels found in some free-living big brown bats, PCBs may be slowing metabolic rates of some free-living bats. It is not known how various common organochlorine residues may affect metabolism in hibernating bats.

    This document illustrates guidelines for the efficient installation of interior duct systems in new housing, including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. This document illustrates guidelines for the efficient installation of interior duct systems in new housing. Interior ducts result from bringing the duct work inside a home's thermal and air barrier. Architects, designers, builders, and new home buyers should thoroughly investigate any opportunity for energy savings that is as easy to implement during construction, such as the opportunity to construct interior duct work. In addition to enhanced energy efficiency, interior ductwork results in other important advantages, such as improved indoor air quality, increased system durability and increased homeowner comfort. While the advantages of well-designed and constructed interior duct systems are recognized, the implementation of this approach has not gained a significant market acceptance. This guideline describes a variety of methods to create interior ducts including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. As communication of the intent of an interior duct system, and collaboration on its construction are paramount to success, this guideline details the critical design, planning, construction, inspection, and verification steps that must be taken. Involved in this process are individuals from the design team; sales/marketing team; and mechanical, insulation, plumbing, electrical, framing, drywall and solar contractors.

  19. From Energy Audits to Home Performance: 30 Years of Articles in Home Energy Magazine

    Energy Technology Data Exchange (ETDEWEB)

    Meier, Alan

    2014-08-11

    Home Energy Magazine has been publishing articles about residential energy efficiency for 30 years. Its goal has been to disseminate technically reliable and neutral information to the practitioners, that is, professionals in the business of home energy efficiency. The articles, editorials, letters, and advertisements are a kind of window on the evolution of energy conservation technologies, policies, and organizations. Initially, the focus was on audits and simple retrofits, such as weatherstripping and insulation. Instrumentation was sparse sometimes limited to a ruler to measure depth of attic insulation and a blower door was exotic. CFLs were heavy, awkward bulbs which might, or might not, fit in a fixture. Saving air conditioning energy was not a priority. Solar energy was only for the most adventurous. Thirty years on, the technologies and business have moved beyond just insulating attics to the larger challenge of delivering home performance and achieving zero net energy. This shift reflects the success in reducing space heating energy and the need to create a profitable industry by providing more services. The leading edge of the residential energy services market is becoming much more sophisticated, offering both efficiency and solar systems. The challenge is to continue providing relevant and reliable information in a transformed industry and a revolutionized media landscape.

    1964-01-01

    In the framework of research carried out on a CO 2 -cooled power reactor moderated by heavy water, the so-called 'pressure vessel' solution involves the total integration of the core, of the primary circuit (exchanges and blowers) and of the fuel handling machine inside a single, strong, sealed vessel made of pre-stressed concrete. A vertical design has been chosen: the handling 'attic' is placed above the core, the exchanges being underneath. This solution makes it possible to standardize the type of reactor which is moderated by heavy-water or graphite and cooled by a downward stream of carbon dioxide gas; it has certain advantages and disadvantages with respect to the pressure tube solution and these are considered in detail in this report. Extrapolation presents in particular.problems due specifically to the heavy water (for example its cooling,its purification, the balancing of the pressures of the heavy water and of the gas, the assembling of the internal structures, the height of the attic, etc. (authors) [fr

    2014-01-01

    Highlights: • Constructing a new design of sustainable roofing systems. • An innovative roofing system (IRS) for tropical landed houses is proposed. • Separate solar heat from useful natural light by physical form. • The IRS can maintain an illuminance level of approximately 86–100% below 2000 lux. • The IRS can reduce the attic air temperature by 5.4 °C and the indoor air temperature by 2.1 °C. - Abstract: An innovative roofing system (IRS) is designed to deliver an abundant and uniform amount of cool natural light from the roof with reduced heat gain effect for tropical residential buildings (3 m height) in Malaysia. Studies revealed that several passive and active solar techniques can be integrated to form a roofing system to separate solar heat from useful natural light at the attic zone before heat reaches the occupied space. The IRS design is specified and proposed by using glazing technology (polycarbonate), pigment technique (reflective and radiative), as well as ventilation process (hybrid turbine ventilator) applied at the attic zone to represent a new model of sustainable roofing design. The aim of this research is to demonstrate the effectiveness of the design concept without the need for any chemical, complex, or expensive solar design techniques. The methodology was conducted on a series of field studies in a standard room model at Universiti Sains Malaysia. Three different roofing systems are investigated to identify the IRS performance in both dark and daylight conditions to determine the effect of natural light on the indoor environment. The outcomes of the design show that the IRS was able to reduce the indoor air temperature compared with conventional roofing system by approximately 2.1 °C under daylight condition. Results showed that the difference in the IRS (daylight–dark) condition was 0.31 °C compared to that in the conventional roofing system at 0.8 °C. Furthermore, the level of mean radiant temperature compared with

    Full Text Available On the basis of a corpus edition of Attic grave stelae, it becomes possible to make certain broad observations about the nature and development of Greek relief sculpture, a branch of the arts in which the Greeks are admitted to have excelled. Archaeology has added so much to our knowledge in the course of the 19th century that we can dismiss the earlier assumption that these sculptures did not have colour. In fact they were painted, and the evidence shows that in spite of its severe technical limitations, Greek relief sculpture developed in an increasingly painterly direction, in tandem with the development of Greek wall and panel painting as we know it – more so than vase painting. St. Remy and Pergamon provide examples of the prodigious Greek application of the genre, where ‘there were no innovations left for Roman art to make’.

    The market seems ready for a private power plant on the wall in the attic, which also heats the house. Such an installation is the successor of the high efficiency boiler, which is in use in most of the homes in the Netherlands. After fifteen years of development Dutch companies have taken the lead in this technology. The manufacturer Remeha in Apeldoorn, Netherlands, started one month ago with the production of high efficiency electric boiler. [Dutch] De markt lijkt klaar voor een eigen stroomcentrale aan de muur op zolder die bovendien het huis verwarmt. De installatie is de opvolger van de hoogrendementsketel, die de meeste huizen in Nederland verwarmt. Na vijftien jaar ontwikkeling hebben Nederlandse bedrijven het technologische voortouw genomen. De Apeldoornse fabrikant Remeha is een maand geleden als eerste met serieproductie van de hre-ketel begonnen.

    2011-02-01

    Full Text Available Some bat species have adapted to the expanding human population by acquiring the ability to roost in urban buildings, increasing the exposure risk for people and domestic animals, and consequently, the likelihood of transmitting rabies. Three dead bats were found in the yard of a house in an urban area of Jundiaí city in the state of São Paulo in southeast Brazil. Two of the three bats tested positive for rabies, using Fluorescent Antibody and Mouse Inoculation techniques. A large colony of Eptesicus furinalis was found in the house's attic, and of the 119 bats captured, four more tested positive for rabies. The objectives of this study were to report the rabies diagnosis, characterize the isolated virus antigenically and genetically, and study the epidemiology of the colony.

    Full Text Available To what extent is it possible be reconciled with a tragic past? Could historical narration or dramatic performance help to get over the traumatic event indeed? Or do they just ascertain its constitutive contradictions, the split and the rift from a pain wich is impossible to sublimate? Is the mourning experience based on the recovery of a feeble balance between the opposite drives, emotions and feelings from the will? Or does it depend on the synthetic assimilation of that opposition into another way of life? This essay travels hand in hand with Schiller and Hegel across the space opened by those questions. It starts from the dissatisfaction generated in the young Hegel by his reading of Schiller’s Wallenstein and it analyzes his different conceptions of the ethic pathos, as well as his uneven perspective about the function of the chorus in the Attic tragedy

    The New York State Energy Research and Development Authority (NYSERDA) is interested in finding cost-effective solutions for deep energy retrofits (DERs) related to exterior wall insulation in a cold climate, with targets of 50% peak load reduction and 50% space conditioning energy savings. The U.S. Department of Energy Building America team, IBACOS, in collaboration with GreenHomes America, Inc. (GHA), was contracted by NYSERDA to research exterior wall insulation solutions. In addition to exterior wall insulation, the strategies included energy upgrades where needed in the attic, mechanical and ventilation systems, basement, band joist, walls, and floors. Under Building America, IBACOS is studying the impact of a “thermal enclosure” DER on the sizing of the space conditioning system and the occupant comfort if the thermal capacity of the heating and cooling system is dramatically downsized without any change in the existing heating and cooling distribution system (e.g., size, tightness and supply outlet configurations).

    1978-01-01

    In order to estimate the danger of low level radiation to human beings, the studies of the late-occurring injuries and internal exposure due to radionuclide deposition are necessary. In the National Institute of Radiological Sciences, research on the estimation of the danger of late-occurring injuries due to radiation is proceeding. In this connection, a late-occurring injury laboratory building has been completed recently. Basic ideas behind it are as follows. To carry out the above mentioned studies effectively and efficiently, many experimental animals of high quality must be kept under best possible environment. For the observation in a series of experiments, irradiation room and laboratory rooms are essential. The building comprises the following: the first floor for animal receiving, the second floor for laboratory rooms, the third floor for RI facility and X-ray irradiated animal keeping, the fourth floor for SPF animal keeping, and attic floor for water supply, etc. (J.P.N.)

    2009-02-01

    Currently, dream-enacting behaviors are viewed as occurring typically in association with a REM-sleep behavior disorder. In some cases, dream-like mentation is found also in non-REM parasomnia. We report a case of complex and dramatic sleepwalking behavior in a 26-year-old adult male who tied his 4-month-old daughter to the clothesline in the attic of his house. The explanation of this seemingly senseless behavior, which was related to psychosocial stressors, was found in a detailed dream-like mentation that was reported by the patient. At the same time, an organic factor, namely, a worsening of the patient's asthma, was identified as the cause of an increased fragmentation of sleep. In some cases of non-REM parasomnia, detailed dream-like mentation may act as a bridge between psychosocial stressors and the specific parasomnic behavior.

  11. Reducing Thermal Losses and Gains With Buried and Encapsulated Ducts in Hot-Humid Climates

    Energy Technology Data Exchange (ETDEWEB)

    Shapiro, C.; Magee, A.; Zoeller, W.

    2013-02-01

    The Consortium for Advanced Residential Buildings (CARB) monitored three houses in Jacksonville, FL, to investigate the effectiveness of encapsulated and encapsulated/buried ducts in reducing thermal losses and gains from ductwork in unconditioned attics. Burying ductwork beneath loose-fill insulation has been identified as an effective method of reducing thermal losses and gains from ductwork in dry climates, but it is not applicable in humid climates where condensation may occur on the outside of the duct jacket. By encapsulating the ductwork in closed cell polyurethane foam (ccSPF) before burial beneath loose-fill mineral fiber insulation, the condensation potential may be reduced while increasing the R-value of the ductwork.

    Full Text Available In Lucian’s Scythian (§11, all previous editors have corrected the word ἀπάξεται as it appears in the manuscripts to ἐπάξεται. We aim to justify the restoration of the original text because, obviously, it is possible in terms of form, and, besides, it seems more appropriate to the context. The verb ‚págomai implies the notion of being moved from one place to another, while ἐπάγομαι expresses only the notion of simple attraction which does not involve actual movement. This notion of true surrendering through the senses seems to match the idea developed here by Lucian; loci paralleli in Lucian himself and other Attic authors help us to confirm this interpretation

    Waste from Electrical and Electronic Equipment (WEEE) is the fastest growing waste fraction in Europe and is classified as hazardous as it may include substances that have adverse effects on human health or cause damage to the environment (UNEP, 2009). The European Community Directive 2002/96/EC...... on Waste Electrical and Electronic Equipment (WEEE Directive), together with the European Community Directive 2002/95/EC on the Restriction of Hazardous Substances (RoHS Directive) were established respectively to set collection, recycling and recovery targets, and to restrict the use of six hazardous......, there is a gap between the reporting of produced and collected amounts of WEEE. This is attributable to three factors: unclear reporting obligation for business to business WEEE producers, attic effect, and improper disposal of WEEE from the consumers. Secondly, despite the restrictions introduced by the Ro...

    2007-01-01

    We developed a new grading system to understand the complicated pathological changes of cholesteatoma in comparison to those of chronic otitis media. This grading system, based on the extent of the cholesteatoma and the surrounding pathlogical changes, is able to simply express the entire pathological condition of the ear with cholesteatoma. Using this grading system, we analyzed the ears of 48 children with cholesteatoma, who underwent tympanoplasty over the past ten years. Their ages ranged from 2 to 15 years with an average age of 8.5 years. The attic and mesotympanic cholesteatomas were associated with greater pathological changes than those observed in postero-superior quadrant cholesteatomas. The degree of the pathological change in the area surrounding the cholesteatoma appears to correlate with the degree of extention of the cholesteatoma. This system is thus considered to be useful for evaluating the improvement in the pathological conditions before and after surgery in patients with cholesteatoma. (author)

    A new mortar for thermal insulation of medieval church vaults was tested in a full scale experiment in Annisse Church, DK. The mortar consists of perlite, a highly porous aggregate, mixed with slaked lime. These materials are compatible with the fired clay bricks and the lime mortar joints....... The lambda-value of the insulation mortar is 0.08 W/m K or twice the lambda-value for mineral wool. The water vapour permeability is equal to a medieval clay brick, and it has three times higher capacity for liquid water absorption. The mortar was applied to the top side of the vaults in a thickness of 10 cm......, despite a water vapour pressure gradient up to 500 Pa between the nave and attic. There was no reduction in energy consumption the first winter, possibly due to the increased heat loss related to the drying of the mortar....

    Wind-powered bioventing systems were designed to operate at remote locations in the absence of electrical power. Laboratory measurements of soil respiration under bioventing conditions indicated the biodegradation of up to 25 mg of weathered diesel per kg of site soil per day. Further testing demonstrated the potential for harnessing wind-power to stimulate air movement through vadose zone soil. A 12-in. attic turbine in a 10-mph wind was found to generate 0.025 in. of water vacuum with an airflow of approximately 2.5 ft 3 per min. Two wind-powered bioventing systems were installed near Nome, Alaska. In situ respiration tests and soil gas composition measurements indicated that the systems were capable of aerating the soil. Measurements of diesel-range organics (DRO) taken during installation and at the end of the treatment season show concentration reductions of 29 and 87% at the two sites

    The factors which contribute to indoor radon levels were investigated. Soil moisture content appears to be such a factor and influences indoor radon levels in a subtle way. The single family dwelling studied here is a typical suburban home, with a full basement, two living levels and a full attic. Seasonal data for 1981 to 1983 are shown by hour (about 90 hours in each average) for the basement, first floor and outdoors. A twenty-five story, 225 apartment, high rise building has been under study for about the same time interval. The apartment has five rooms, and is on the 24th floor. Continuous monitors are located in a work room and outdoors on a terrace. Data are available from the summer of 1981. 2 references, 12 figures, 9 tables

  19. Measured airtightness of twenty-four detached houses over periods of up to three years

    1992-01-01

    A three year field study of 20 energy efficient houses and four conventional dwellings was conducted in Winnipeg, Manitoba to evaluate the performance of their building envelope systems. Ten of the houses were built with polyethylene air barriers and 14 using the Airtight Drywall Approach (ADA). All were newly constructed and used dry wood for the framing members with a wood moisture content (WMC) below 19 percent. Building envelope performance was evaluated by developing a comprehensive monitoring program which included measurements of wall, attic, and floor joist WMC levels, detailed thermographic examinations and regular airtightness testing. Over 13,000 WMC measurements were performed, 1,013 thermographic images recorded, and 167 airtightness tests conducted.

    Test houses with unvented roof assemblies were built to measure long-term moisture performance, in the Chicago area (5A) and the Houston area (2A). The Chicago-area test bed had seven experimental rafter bays, including a control vented compact roof, and six unvented roof variants with cellulose or fiberglass insulation. The interior was run at 50% RH. The Houston-area roof was an unvented attic insulated with spray-applied fiberglass. Most ridges and hips were built with a diffusion vent detail, capped with vapor permeable roof membrane. In contrast, the diffusion vent roofs had drier conditions at the roof peak in wintertime, but during the summer, RHs and MCs were higher than the unvented roof (albeit in the safe range).

    From surveys in many countries, we report raptors using unusual nesting materials (e.g., paper money, rags, metal, antlers, and large bones) and unusual nesting situations. For example, we documented nests of Steppe Eagles Aquila nipalensis and Upland Buzzards Buteo hemilasius on the ground beside well-traveled roads, Saker Falcon Falco cherrug eyries in attics and a cistern, and Osprey Pandion haliaetus nests on the masts of boats and on a suspended automobile. Other records include a Golden Eagle A. chrysaetos nest 7.0 m in height, believed to be the tallest nest ever described, and, for the same species, we report nesting in rudimentary nests. Some nest sites are within a few meters of known predators or competitors. These unusual observations may be important in revealing the plasticity of a species' behavioral repertoire. ?? 2009 The Raptor Research Foundation, Inc.

  2. Low-Cost Phase Change Material for Building Envelopes

    2015-08-06

    A low-cost PCM process consisting of conversion of fats and oils to PCM-range paraffins, and subsequent “encapsulation” of the paraffin using conventional plastic compounding/pelletizing equipment was demonstrated. The PCM pellets produced were field-tested in a building envelope application. This involved combining the PCM pellets with cellulose insulation, whereby 33% reduction in peak heat flux and 12% reduction in heat gain was observed (average summertime performance). The selling price of the PCM pellets produced according to this low-cost process is expected to be in the $1.50-$3.00/lb range, compared to current encapsulated PCM price of about $7.00/lb. Whole-building simulations using corresponding PCM thermal analysis data suggest a payback time of 8 to 16 years (at current energy prices) for an attic insulation retrofit project in the Phoenix climate area.

    The 37 Sr/ 36 Sr ratios of the Tethys Sea have been determined by analyzing limestones of Permian to Late Cretaceous age from the overthrusted sequence of central and northern Euboea. The results are in satisfactory agreement with ratios obtained by other investigators on unreplaced fossil shells of similar age collected elsewhere. The 37 Sr/ 36 Sr ratios of Mesozoic marbles from the autochtone metamorphic rocks of southern Euboea are more variable, perhaps because of increases in this ratio during regional metamorphism. Nevertheless, the lowest values of suites of isochronous samples may approach the correct ratio. Four samples of the Argyron Marble taken at different localities in southern Euboea and on the Attic peninsula have a concordant 87 Sr/ 86 Sr ratio of 0.70688+-0.00006 relative to 0.7080 for the Eimer and Amend isotope standard. This value indicates a Jurassic age for this formation even though the fragmentary fossil evidence favors a Late Cretaceous (Turonian) age

  8. Experimental feeding of DDE and PCB to female big brown bats (Eptesicus fuscus)

    Clark, D.R.; Prouty, R.M.

    1977-01-01

    Twenty-two female big brown bats (Eptesicus fuscus) were collected in a house attic in Montgomery County, Maryland. Seventeen were fed mealworms (Tenebrio molitor larvae) that contained 166 ppm DDE; the other five were fed uncontaminated mealworms. After 54 days of feeding, six dosed bats were frozen and the remaining 16 were starved to death. In a second experiment, 21 female big brown bats were collected in a house attic in Prince Georges County, Maryland. Sixteen were fed mealworms that contained 9.4 ppm Aroclor 1254 (PCB). After 37 days, two bats had died, four dosed bats were frozen, and the remaining 15 were starved to death. Starvation caused mobilization of stored residues. After the feeding periods, average weights of all four groups (DDE-dosed, DDE control, PCB-dosed, PCB control) had increased. However, weights of DDE-dosed bats had increased significantly more than those of their contols, whereas weights of PCB-dosed bats had increased significantly less than those of their controls. During starvation, PCB-dosed bats lost weight significantly more slowly than controls. Because PCB levels in dosed bats resembled levels found in some free-living big brown bats, PCBs may be slowing metabolic rates of some free-living bats. It is not known how various common organochlorine residues may affect metabolism in hibernating bats. DDE and PCB increased in brains of starving bats as carcass fat was metabolized. Because the tremors and/or convulsions characteristic of neurotoxicity were not observed, we think even the maximum brain levels attained (132 ppm DDE, 20 ppm PCB) were sublethal. However, extrapolation of our DDE data predicted lethal brain levels when fat reserves declined sufficiently. PCB-dosed bats were probably in no danger of neurotoxic poisoning. However, PCB can kill by a nonneurotoxic mode, and this could explain the deaths of two bats on PCB dosage.

    In a study of the middle ear cleft in otitis media with effusion (OME), high-resolution computed tomography was performed in 51 patients aged 3 to 13 years. The patients were divided into the following three groups; group I, fresh cases without any treatment; group II, recurrent or chronic cases; group III, cases with sequelae as a result of OME. 1) In group I, the entire middle ear cavity was occupied with material of soft-tissue density in 18 out of 21 ears. The incidence of soft-tissue density was 100% in the mastoid air cells, 95% in the mastoid antrum, 93% in the attic and 88% in the tympanic cavity. The percentage thus rose with the distance from the tympanic cavity. 2) There was no significant difference in the incidence of soft-tissue density between groups I and II. 3) In group III, the mastoid air cells showed density, while the other regions had adequate air-containing spaces. 4) Even after myringotomy and aspiration of the fluid in group I, density was found in the mastoid air cells in 100% of the cases. Density in the mastoid antrum, attic and tympanic cavity was present in 43%, 21% and 21% of the cases, respectively. These results suggest that lesions are likely to persist in regions away from the orifice of myringotomy and that this therapy can not eliminate all of the lesions. In group II, the soft-tissue density in the middle ear was eliminated by myringotomy better than in group I. 5) The effect of ventilating tubes on the mastoid air cells was not determined and requires further studies.

The basic nuclei of the apartments are clearly separated into zones daytime living quarters, night quarters and services. It is noteworthy that passages have been largely eliminated, and circulation problems have been otherwise solved, avoiding to some extent the crossing of the main lines of human circulation. The area devoted to social life has been increased as far as possible, and its environment has been enlarged by means of balcony-terraces. The fine aesthetic quality of the building, in its external aspect, is largely due to the clever way in which the materials have been used, exploiting their textures and combining these harmoniously.Ha sido construida sobre un solar de 1.991,41 m2 y consta de 29 viviendas distribuidas en cinco plantas- tipo, ático, doble ático y entreplanta.

    1992-05-01

    A three year field study of 20 energy efficient houses and four conventional dwellings was conducted to evaluate the performance of their building envelope systems. Ten of the houses were built with polyethylene air barriers and 14 using the airtight drywall approach (ADA). All were newly built and used dry wood for framing members, i.e. with a wood moisture content (WMC) below 19%. Building envelope performace was evaluated by developing a comprehensive monitoring program which included measurements of wall, attic and floor joist WMC levels, detailed thermographic examinations and regular airtightness testing. Over 13,000 WMC measurements were performed, 1013 thermographic images recorded and 167 airtightness tests conducted. Both the energy efficient and conventional building envelope systems performed satisfactory manner although fewer problems were found in the energy efficient houses. Lower mean WMC levels were measured in the walls and attics and fewer WMC excursions above 19% were recorded. The energy efficient houses also displayed fewer thermographic anomalies, particulary those of a severe nature. The energy efficient houses were found to be more airtight. No evidence of envelope degradation was found in the energy efficient houses. Both the polyethylene air barriers and the ADA system demonstrated predominately stable WMC levels, thermographic characteristics and airtightness. The building envelopes constructed using polyethylene barriers generally performed in a superior fashion to those which used ADA, although both systems provided satisfactory performance. WMC levels were slightly lower in the polyethylene houses as were the number of thermographic faults, particularly those of a severe nature. 11 refs., 28 figs., 10 tabs.

  15. Cellulose insulation as an air barrier

    Energy Technology Data Exchange (ETDEWEB)

    Manning, K.

    1989-10-01

    The objective of this study was to determine if a wet sprayed cellulose wall insulation system would function satisfactorily without use of a polyethylene air/vapour barrier. The research was designed to demonstrate that this particular insulation system would form enough of a barrier to air leakage, that moisture accumulation from condensation and vapour diffusion would be insignificant. Field work conducted in Alberta, involved construction of a conventional duplex housing unit which was insulated with wet sprayed cellulose in the exterior walls and dry loose-fill cellulose in the attic areas. One half of the unit did not have a polyethylene air/vapor barrier installed. Air leakage and exterior wall moisture levels were monitored for a year following construction. Data collected during this time indicated that the moisture added to the walls during the insulating process was dissipated over the study period. The presence of polyethylene sheeting had no significant effect on the moisture levels in either the wall or attic areas of the test structure. On the other hand, testing indicated that the use of polyethylene sheeting in the wall system did serve to improve blower door air test results. In conclusion, although the air leakage resistance apparently provided by the polyethylene sheeting is significant, the amount is probably not more than could otherwise be obtained by more careful attention to sealing procedures such as those used in the airtight drywall technique. A more important finding is that the use of polyethylene sheeting is not essential in a structure which has the degree of air leakage resistance provided by the insulation system used in this project. 6 figs., 2 tabs.

  17. Study of new structures adapted to gas-graphite and gas-heavy water reactors

    Martin, R.; Roche, R.

    1964-01-01

    The experience acquired as a result of the operation of the Marcoule reactors and of the construction and start-up of the E.D.F. reactors on the one hand, and the conclusions of research and tests carried out out-of-pile on the other hand, lead to a considerable change in the general design of reactors of the gas-graphite type. The main modifications envisaged are analysed in the paper. The adoption of an annular fuel element and of a down-current cooling will make it possible to increase considerably the specific power and the power output of each channel; as a result there will be a considerable reduction in the number of the channels and a corresponding increase in the size of the unit cell. The graphite stack will have to be adapted to there new conditions. For security reasons, the use of prestressed concrete for the construction of the reactor vessel is becoming more widespread; they could lead to the exchangers and the fuel-handling apparatus becoming integrated inside the vessel (the so-called 'attic' device). A full-size mode) of this attic has been built at Saclay with the participation of EURATOM; the operational results obtained are presented as well as a new original design for the control rods. As for as the gas-heavy-water system is concerned, the research is carried out on two points of design; the first, which retains the use of horizontal pressure tubes, takes into account the experience acquired during the construction of the EL 4 reactor of which it will constitute an extrapolation; the second, arising from the research carried out on the gas-graphite system, will use a pre-stressed concrete vessel for holding the pressure, the moderator being almost at the same pressure as the cooling fluid and the fuel being placed in vertical channels. The relative merits of these two variants are analysed in the present paper. (authors) [fr

  18. Advanced Energy Efficient Roof System

    Energy Technology Data Exchange (ETDEWEB)

    Jane Davidson

    2008-09-30

    Energy consumption in buildings represents 40 percent of primary U.S. energy consumption, split almost equally between residential (22%) and commercial (18%) buildings.1 Space heating (31%) and cooling (12%) account for approximately 9 quadrillion Btu. Improvements in the building envelope can have a significant impact on reducing energy consumption. Thermal losses (or gains) from the roof make up 14 percent of the building component energy load. Infiltration through the building envelope, including the roof, accounts for an additional 28 percent of the heating loads and 16 percent of the cooling loads. These figures provide a strong incentive to develop and implement more energy efficient roof systems. The roof is perhaps the most challenging component of the building envelope to change for many reasons. The engineered roof truss, which has been around since 1956, is relatively low cost and is the industry standard. The roof has multiple functions. A typical wood frame home lasts a long time. Building codes vary across the country. Customer and trade acceptance of new building products and materials may impede market penetration. The energy savings of a new roof system must be balanced with other requirements such as first and life-cycle costs, durability, appearance, and ease of construction. Conventional residential roof construction utilizes closely spaced roof trusses supporting a layer of sheathing and roofing materials. Gypsum board is typically attached to the lower chord of the trusses forming the finished ceiling for the occupied space. Often in warmer climates, the HVAC system and ducts are placed in the unconditioned and otherwise unusable attic. High temperature differentials and leaky ducts result in thermal losses. Penetrations through the ceilings are notoriously difficult to seal and lead to moisture and air infiltration. These issues all contribute to greater energy use and have led builders to consider construction of a conditioned attic. The

The labial stop of σβέννυμι is the only regular treatment of *sgu̯es- we can expect in Greek, the palatalization of g-u̯ being ruled out after s; on the contrary, the regular palatalization gu̯e > dze took place in *gṷes-, as seen in the gloss ζείναμεν, which is, in the author's view, an iotacistic spelling for an Arcadian form * ζήναμεν [dzḗnamen]. Coexistence of -nū- and -nā- presents is very scarcely attested in Greek, since the -nā- suffix was not productive any longer in the earliest stages of this language. Such nasal presents as *sgu̯ésnūmi (and *gu̯ésnāmi, *dzṓsnūmi, * u̯ésnūmi arose, at least in East Greek, before the first compensatory lengthening, i. e., before the splitting of Attic-Ionic (*sgu̯ẹ̄́nūmi and Achaean (arc. *gu̯ḗnāmi.

    The objective of this research was to obtain thermal performance data for reflective insulations in a South East Asia environment. Thermal resistance data (RSI, m2 ṡ K/W) for reflective insulations are well established from 1-D steady-state tests, but thermal data for reflective insulation in structures like those found in South East Asia are scarce. Data for reflective insulations in South East Asia will add to the worldwide database for this type of energy-conserving material. RSI were obtained from heat flux and temperature data of three identical structures in the same location. One unit did not have insulation above the ceiling, while the second and third units were insulated with reflective insulation with emittance less than 0.05. RSI for the uninsulated test unit varied from 0.37 to 0.40 m2 ṡ K/W. RSI for a single-sheet reflective insulation (woven foil) varied from 2.15 to 2.26 m2 ṡ K/W, while bubble-foil insulation varied from 2.69 to 3.09 m2 ṡ K/W. The range of RSI values resulted from differences in the spacing between the reflective insulation and the roof. In addition, the reflective insulation below the roof lowered attic temperatures by as much as 9.7° C. Reductions in ceiling heat flux of 80 to 90% relative to the uninsulated structure, due to the reflective insulation, were observed.

  4. Case study: Managing potentially contaminated records

    For the past 10 or more years, Analytical Laboratory data cards have been generated and stored in the 222-S Laboratory at the Hanford Site in Richland, Washington. These cards are classified as record material and require retention for a minimum of 75 years in an approved storage facility in accordance with Westinghouse Hanford Company procedures. The cards are maintained in records boxes in the attic of the 222-S Laboratory and are subject to potential risk and loss. The most significant potential risks are radiological hazards. Various options are available for removal, cataloging, transmittal, and storage of these long-term records. Because the records are currently stored in a radiation protection zone, they surveyed before being released from the facility. This survey can be arduous and time consuming. Resolutions to the problem of removal and proper storage of the records from the facility need to be addressed. The records were reviewed and inventoried to determine the quantity of information. A study of the various options available was conducted, and based on the information collected, it was determined that the most feasible and cost-effective approach is to microfilm the cards inside the laboratory. This option complies with all applicable company requirements and decreases the estimated radiological survey time from approximately 3.5 years to under 40 hours. This activity will result in a potential savings of $350,000 over the life of the activity

    2004-01-01

    In many municipalities, there are district heating networks, which are quite commonly supplied by combined heat and power plants (CHP). A district heating network contains buildings of different types. In this paper, one such municipal energy system is analysed. In order to provide space heating and domestic hot water, investments could be made on the supply side in power plants, or on the demand side in the buildings, for example in the form of extra wall insulation. The electricity from the CHP plants is supplied to the municipality but can also be sold to the electricity market, and electricity can, of course, also be bought from the market. The variation in price on the spot market over any given day is significant. The need for district heat in the building stock also varies, for example due to climatic conditions. The energy system in the case study is analysed with a mixed integer linear programming model. The model has 3 h time steps in order to reflect diurnal variations, and an entire year is analysed. A case study is presented for the city of Linkoeping in Sweden. On the demand side, the options are: extra wall insulation, extra attic insulation and better types of windows. The building stock is divided into nine categories

    2013-03-01

    Vernacular architecture of any settlement is characterized by architecture and construction methods developed by the wisdom of the local masons and builders, often the inhabitants themselves, to provide thermal comfort to users in extreme outdoor uncomfortable climatic conditions, by using locally available building materials and by adopting construction technology which both were more responsive to their climatic and geographic condition. This paper will highlight the climate-responsiveness in the traditional architecture of Khyah village in Hamirpur district of Himachal Pradesh, having sub-tropical climatic condition. The plan of individual house, the cluster of houses and the overall settlement itself has been evolved from a process of understanding the local geo-climatic conditions which causes discomfort in both cold winter and hot summer months. Hence, the house plans were kept compact, thick adobe bricks were used for walls, pitched roof with attic and roof-covering of slate were employed and small window openings were provided with heavy timber shutter—all as a mean to retain indoor heat during cold winter months and also to prevent excessive heat-loss and heat-gains. The paper will also attempt to bring out the adaptive synchronized dynamic interactions between the various activities of inhabitants and their spatial environment, as a response to the local climatic conditions, from the physical survey of this traditional hill settlement.

    The report describes material behaviour, which significantly influences the settling of loose-fill insulation materials. The specific application presented here is loose-fill insulation material injected in walls as thermal insulation. The physical formulation of the issue to be discussed is that the mass is kept in position in the cavity by frictional forces, which counteracts the settling but complicates injection. The purpose of this study is to investigate whether there is a possibility that decreased friction will be able to release settling. Cellulose loose-fill material injected in a 0.1 m thick and 1 m wide gypsum wall with a minimum density of 48 kg/m3 was found not to settle if kept at a constant relative humidity, RH 50 %. A minimum density of 53 kg/m3 is necessary if the thickness of the wall is increased from 0.1 m to 0.3 m. If changing the constant environment from RH 50 % to RH 80 % a minimum density of 63 kg/m3 is necessary. Furthermore, results so far show that cellulose loose-fill material spread on the attic floor will have a density after settling of 48 kg /M3 for a constant RH 50 %, corresponding to 43 kg/m3 dry material. The results were found by using a model and tests. (au)

    Adult female little brown bats (Myotis lucifugus) were collected in a church attic in North East, Cecil County, Md. Mealworms (Tenebrio molitor) containing organochlorine pollutants were fed to the bats as follows: 5 bats were dosed at 480 ppm DDE, 12 at 150 ppm DDE, 5 at 1000 ppm polychlorinated biphenyl (PCB; Aroclor 1260), and 12 at 15 ppm PCB. Seven other bats were fed untreated mealworms. The objective was to elevate brain levels of DDE and PCB to lethality and measure these concentrations. During 40 d of dosage, one DDE-dosed bat and two PCB-dosed bats died after exhibiting the prolonged tremor that characterizes organochlorine poisoning. After dosage, surviving bats were starved to elevate brain levels of toxicants, and three additional DDE-dosed bats had tremors before dying. The mean brain concentration of DDE diagnostic of death was estimated as 603 ppm, range 540-670 ppm. This mean is 16-18% higher than means for Mexican free-tailed bats (Tadarida brasiliensis) and common grackles (Quiscalus quiscula), and may indicate less sensitivity. Lethal brain concentrations of Aroclor 1260 were 1300 and 1500 ppm. Such values appear to be higher than values (Aroclor 1254) for brown-headed cowbirds (Molothrus ater). During starvation, DDE-dosed bats lost weight about 24% faster than controls. If smaller amounts of stored DDE cause increases in metabolic rates of nonfeeding bats, as during hibernation or migration, the result could be premature energy depletion and increased mortality.

    We tested our hypothesis that the oval window (OW) potentially functions as a route to carry substances from the middle ear to the vestibulum and then the scala vestibuli through the annular ligament across the stapediovestibular joint. Gd-DOTA was either injected into the lateral attic compartment of rats with a high-performance polyimide tube in a selective OW delivery group, or administered to the middle ear cavity of two groups of rats in which the OW was either sealed or not sealed. The dynamic uptake of Gd-DOTA in the inner ear was visualized with a 4.7-T magnetic resonance imaging machine. In the selective OW delivery group, Gd-DOTA appeared in the vestibulum and in the basal turn of the scala vestibuli but not in the scala tympani on T1-weighted images acquired at 10 minutes after Gd-DOTA administration (the earliest available time point of magnetic resonance imaging). In the sealed-OW group, immediate uptake of Gd-DOTA was absent in the vestibulum and scala vestibuli. Measurement of the signal ratio of the vestibulum to that of the scala tympani showed that selective OW delivery induced the greatest signal ratio and that sealing of the OW induced the lowest signal ratio. The OW is a genuine and efficient pathway to transport Gd-DOTA from the middle ear to the vestibulum.

    Dichlorodiphenyltrichloroethane (DDT) is an insecticidal organochlorine pesticide with; known potential for neurotoxic effects in wildlife. The United States Environmental Protection Agency (US EPA) registration for this pesticide has been cancelled and there are currently no federally active products that contain this ingredient in the U.S. We present a case of a colony of big brown bats (E. Fuscus) found dead in the attic roost of an administrative building; in the city of Hamilton, Montana from unknown cause. DDT and its metabolites; dichlorodiphenyldichloroethylene (DDE) and dichlorodiphenyldichloroethane (DDD) were detected in bat tissues by gas chromatography/mass spectrometry (GC-MS) and quantified by gas chromatography tandem quadrupole mass spectrometry (GC-MS/MS). Concentrations of 4081 ppm DDT and 890 ppm DDE wet weight were found in the brain of one bat and are the highest reported concentrations in such a mortality event to date. This case emphasizes the importance of testing wildlife mortalities against a comprehensive panel of toxicologic agents including persistent organic pollutants in the absence of other more common disease threats.

    Full Text Available The Centre Block of Canada’s Parliament buildings, National Historic Site of Canada is set to undergo a major rehabilitation project that will take approximately 10 years to complete. In preparation for this work, Heritage Conservation Services (HCS of Public Services and Procurement Canada has been completing heritage documentation of the entire site which includes laser scanning of all interior rooms and accessible confined spaces such as attics and other similar areas. Other documentation completed includes detailed photogrammetric documentation of rooms and areas of high heritage value. Some of these high heritage value spaces present certain challenges such as accessibility due to the height and the size of the spaces. Another challenge is the poor lighting conditions, requiring the use of flash or strobe lighting to either compliment or completely eliminate the available ambient lighting. All the spaces captured at this higher level of detail were also captured with laser scanning. This allowed the team to validate the information and conduct a quality review of the photogrammetric data. As a result of this exercise, the team realized that in most, if not all cases, the photogrammetric data was more detailed and at a higher quality then the terrestrial laser scanning data. The purpose and motivation of this paper is to present these findings, as well provide the advantages and disadvantages of the two methods and data sets.

    This article reported on a food company in Saint-Jean-sur-Richelieu, Quebec that has recently modernized its operations by constructing an entire freezer building. Nutrifrance Ltd made the decision to modernize its facility based on long-term energy savings. Three scenarios were analysed for the construction of the freezer building in terms of interior and exterior walls, panels and shelving. The final plans consisted of a freezer within the building, where the outer walls were used as the structure to insulate against heat loss. A heated attic was built to avoid condensation on top of the freezer. Forced air ventilation with a header space was also integrated. The floor consists of 18 centimetres of reinforced concrete every 13 centimetres, giving a thermal resistance of R40. A rapid defrosting process through hot gas is used to recuperate 100 per cent of the heat. Waste heat is used to heat the floors of the office building, the loading areas, and to warm the hot water. The system is controlled by automated machinery to maximize efficiency and costs. The construction offers optimal thermal comfort for employees, which has helped reduce employee turnover. The economical impact has been significant, even after one year of operation, and the energy savings for the electricity bill is 30 per cent lower than predicted. Nutrifrance chose not to use the lowest bid for construction since the ultimate goal was comfort and security. The company predicts a payback period of 14 years. 5 figs.

    Editor's note: Albert Mason discovered an unpublished paper by Donald Meltzer dating from around 1968 and has made the text available to the IJP. He writes "my best guess is that Meltzer gave me the paper to read/approve about the time I was preparing to move to Los Angeles (1968-69) and that I hastily packed it away with other papers. It got buried, and only came to light recently, kind of like a lost score that turns up in someone's attic!" The patient Meltzer discusses in his paper is a patient who Dr Mason treated for approximately 11 years, and about whom Dr Mason consulted with Dr Meltzer early in the treatment. Dr Mason has also provided the original report he wrote about the patient in the 1960s. Following an introduction by Dr Abbot Bronstein, we have published extracts from Dr Mason's report, including the following: details about the case, the two dreams which Dr Mason believes were 'turning point dreams', and a third dream called the 'hula hula dream', as well as the clinical material leading up to it.

    Triangular enclosures are typical configurations of attic spaces found in residential as well as industrial pitched-roof buildings. Natural convection in triangular rooftops has received considerable attention over the years, mainly on right-angled and isosceles enclosures. In this paper, a finite volume CFD package is employed to study the laminar air flow and temperature distribution in asymmetric rooftop-shaped triangular enclosures when heated isothermally from the base wall, for aspect ratios (AR) 0.2 <= AR <= 1.0, and Rayleigh number (Ra) values 8 × 105 <= Ra <= 5 × 107. The effects of Rayleigh number and pitch angle on the flow structure and temperature distributions within the enclosure are analysed. Results indicate that, at low pitch angle, the heat transfer between the cold inclined and the hot base walls is very high, resulting in a multi-cellular flow structure. As the pitch angle increases, however, the number of cells reduces, and the total heat transfer rate progressively reduces, even if the Rayleigh number, being based on the enclosure height, rapidly increases. Physical reasons for the above effect are inspected.

    Described herein are the results of the FY1994 research program for investigation for popular type snow melting systems using solar energy. Two types of technologies are proposed to utilize solar energy for snow melting in winter and create comfortable environments. One is combined (active plus passive) type, which transfers solar heat it collects by the whole wall surfaces to an attic to heat it totally, and makes the whole roof as a radiator to melt snow. However, heat radiated from the roof is insufficient to melt all snow on the roof, allowing it to remain to an extent that it works as an insulator. The other is active type, which transfers heat it collects by the collector to the heat storage tank, from which heat is extracted in winter for various purposes, including snow melting. Such a system must store heat for an extended period, for which a highly insulating heat storage tank is proposed to balance capacity of heat storage between seasons and building size.

    On February 18, 1992, Louisiana State University with two technical subcontractors, BDM, Inc. and ICF, Inc., began a research program to estimate the potential oil and gas reserve additions that could result from the application of advanced secondary and enhanced oil recovery technologies and the exploitation of undeveloped and attic oil zones in the Gulf of Mexico oil fields that are related to piercement salt domes. This project is a one year continuation of this research and will continue work in reservoir description, extraction processes, and technology transfer. Detailed data will be collected for two previously studies reservoirs: a South Marsh Island reservoir operated by Taylor Energy and one additional Gulf of Mexico reservoir operated by Mobil. Additional reservoirs identified during the project will also be studied if possible. Data collected will include reprocessed 2-D seismic data, newly acquired 3-D data, fluid data, fluid samples, pressure data, well test data, well logs, and core data/samples. The new data will be used to refine reservoir and geologic characterization of these reservoirs. Further laboratory investigation will provide additional simulation input data in the form of PVT properties, relative permeabilities, capillary pressure, and water compatibility. Geological investigations will be conducted to refine the models of mud-rich submarine fan architectures used by seismic analysts and reservoir engineers. Research on advanced reservoir simulation will also be conducted. This report describes a review of fine-grained submarine fans and turbidite systems.

    Physics can explain many of the things that we commonly encounter. It can tell us why the night is dark, what causes the tides, and even how best to catch a baseball. With In Praise of Simple Physics, popular math and science writer Paul Nahin presents a plethora of situations that explore the science and math behind the wonders of everyday life. Roaming through a diverse range of puzzles, he illustrates how physics shows us ways to wring more energy from renewable sources, to measure the gravity in our car garages, to figure out which of three light switches in the basement controls the light bulb in the attic, and much, much more. How fast can you travel from London to Paris? How do scientists calculate the energy of an atomic bomb explosion? How do you kick a football so it stays in the air and goes a long way downfield? Nahin begins with simpler problems and progresses to more challenging questions, and his entertaining, accessible, and scientifically and mathematically informed explanations are all punc...

    This project evaluates the renovation of a 5,800 ft2, multi-use facility located in St. Petersburg, on the west coast of central Florida, in the hot humid climate. An optimal package of retrofit measures was designed to deliver 30%-40% annual energy cost savings for this building with annual utility bills exceeding $16,000 and high base load consumption. Researchers projected energy cost savings for potential retrofit measures based on pre-retrofit findings and disaggregated, weather normalized utility bills as a basis for simulation true-up. A cost-benefit analysis was conducted for the seven retrofit measures implemented; adding attic insulation and sealing soffits, tinting windows, improving whole building air-tightness, upgrading heating and cooling systems and retrofitting the air distribution system, replacing water heating systems, retrofitting lighting, and replacing laundry equipment. The projected energy cost savings for the full retrofit package based on a post-retrofit audit is 35%. The building's architectural characteristics, vintage, and residential and commercial uses presented challenges for both economic projections and retrofit measure construction.

    This report discusses changes in indoor temperatures in response to retrofit improvements. The data on which this analysis is based are from an evaluation of the Bonneville Power Administration (BPA) interim Residential Weatherization Program. The BPA program, operated through participating private and public utilities throughout the Pacific Northwest, offered financial assistance (generally a cash rebate) to encourage installation of energy-efficiency improvements to existing homes in the region. These retrofits included attic, wall, floor and heating duct insulation; storm windows and doors; clock thermostats; and caulking and weatherstripping. This program, which operated during 1982 and 1983, weatherized 104 thousand homes at a total cost to BPA of $157 million. In mid-1983, staff at Oak Ridge National Laboratory and Evaluation Research Corporation began an evaluation of the BPA program. The primary focus of this evaluation was assessment of the actual electricity saving that can be attributed to the program (Hirst, et al., 1985). These savings estimates were used to help assess the economic attractiveness of the program to participants, the BPA power system, and the Pacific Northwest region as a whole.

  5. Approaches to identifying reservoir heterogeneity and reserve growth opportunities from subsurface data: The Oficina Formation, Budare field, Venezuela

    We applied an integrated geologic, geophysical, and engineering approach devised to identify heterogeneities in the subsurface that might lead to reserve growth opportunities in our analysis of the Oficina Formation at Budare field, Venezuela. The approach involves 4 key steps: (1) Determine geologic reservoir architecture; (2) Investigate trends in reservoir fluid flow; (3) Integrate fluid flow trends with reservoir architecture; and (4) Estimate original oil-in-place, residual oil saturation, and remaining mobile oil, to identify opportunities for reserve growth. There are three main oil-producing reservoirs in the Oficina Formation that were deposited in a bed-load fluvial system, an incised valley-fill, and a barrier-strandplain system. Reservoir continuity is complex because, in addition to lateral facies variability, the major Oficina depositional systems were internally subdivided by high-frequency stratigraphic surfaces. These surfaces define times of intermittent lacustrine and marine flooding events that punctuated the fluvial and marginal marine sedimentation, respectively. Syn and post depositional faulting further disrupted reservoir continuity. Trends in fluid flow established from initial fluid levels, response to recompletion workovers, and pressure depletion data demonstrated barriers to lateral and vertical fluid flow caused by a combination of reservoir facies pinchout, flooding shale markers, and the faults. Considerable reserve growth potential exists at Budare field because the reservoir units are highly compartment by the depositional heterogeneity and structural complexity. Numerous reserve growth opportunities were identified in attics updip of existing production, in untapped or incompletely drained compartments, and in field extensions.

    Full Text Available We study the mythological treatment of thesymbolic duality between the lýra and the aulós in the ancient  Greek music. We analyze the mythological complex that includes the following narratives: a the invention of the aulós and its later disposal by Athena, b the adoption of the aulós by the Silenus Marsyas, and c the musical duel between Apollo and Marsyas, and its consequences. We compare the mythological approach of this complex in the literary and graphic traditions. Concerning the literary tradition, we focus on the following authors: Pindar (Pythian, XII, Melanipides (ap. Athenaeus, Herodotus, Xenophon (Anabasis, Apollodorus (Library and Ovid (Metamorphoses, Fasti. With respect to the iconographic tradition, we bring mainly the painting of Attic and Apulian vases, as well as the Etruscan vases and mirrors, besides the sculptural groups known by Pliny the Elder and Pausanias. The popularity of this mythological theme, in the literature as in the vase painting, leads us to the philosophical, pedagogic, political and esthetical debate covered by the symbolic dichotomy between aulós and lýra. And furthermore it is an important component of an allegedly hegemonic system of thought, characterized by normative goals concerning culture and social behavior.

    Aim The aim of this article is to review the anatomy of middle ear compartments and folds and to demonstrate through anatomical evidence their presence at birth. Additionally, their role in the obstructions of middle ear ventilatory pathway is highlighted. Methods Ninety-eight adult temporal bones, with no history of auricular disease and fifteen newborn temporal bones were studied by micro dissection. Documentation was done by color photography using the operation microscope Results Our micro-dissections have showed that mucosal folds from the middle ear are steadily present since birth, given that they were found in all newborn temporal bones. The mucosal folds in our normal adult material, showed some variations including membrane defects but they were constantly present. Our micro dissections showed that the epitympanic diaphragm consisted, in addition to malleal ligamental folds and ossicles, of only two constantly present folds: the tensor tympani fold and the incudomalleal fold. When the tensor fold is complete the only ventilation pathway to the anterior epitympanic space is through the isthmus, whereas its absence creates an efficient additional aeration route from the Eustachian tube to the epitympanum. Conclusions The goal of surgery in the chronic pathology of the middle ear should be restoration of normal ventilation of the attical-mastoid area. This is possible by removing the tensor fold and restoring the functionality of the isthmus tympani. PMID:26527977

    Technogenic magnetic particles (TMPs) emitted by various industrial sources, such as smelting plants, end up after atmospheric transfer on the soil surface. In the present study, we characterised the origin and composition of such particles emitted by a large iron smelting plant and deposited on particular substrates, namely tombstones, which act as a very interesting and appropriate matrix when compared to soil, tree bark, lichens or attic dust. The isolation and subsequent description of TMPs require a critical step of separation between different components of the sample and the magnetic particles; here, we described an efficient protocol that fulfils such a requirement: it resorts to water suspension, sonication, repeated magnetic extraction, sedimentation, sieving and organic matter destruction at 550 °C in some instances. The isolated TMPs displayed a noticeable crystalline shape with variable compositions: a) pure iron oxides, b) iron + Cr, Ni or Zn, and c) a complex structure containing Ca, Si, Mg, and Mn. Using Scanning Electron Microscope Energy Dispersive X-ray (SEM–EDX), we obtained profiles of various and distinct magnetic particles, which allowed us to identify the source of the TMPs. - Highlights: • The developed method offers a low-cost approach of large-scale dry deposition. • Tombstones are excellent supports for sampling these atmospheric deposits. • Smelted elements crystallise after cooling, giving typical technogenic magnetic particles (TMPs). • Coupling microscopic and bulk analyses allows identifying TMP origin. • Magnetic TMPs issued from steel industry were separated by a new technique.

    Biography, presumably, the oldest form of historiography, is rudimentally already found in the Attic comedy. Reference is made to Xenophon and his representation of leading personalities and predominance problems as well as to Aristotle through whose school the empiric exploration of the individual personality in philosophy was firmly established. To Theophrast's pictures of human weakness are added new psychological aspects under Aristoxenos. In the biographical work of Nepos the picture of the habits of famous men was shown on a subhistorical level. While Plutarch's character descriptions are fully rationalistic there can be no doubt that a moral value judgement is passed. The Concepts "experience" and "inner development" were therefore unknown in the antique biography. Herder, as the onset of the writing of scientific biographies, is considered the promotor of an objectivating biographical and autobiographical method. Reference is made to Dilthey's theory of knowledge and his theory of cognition, particularly to his cultural-historical approach, whereby a close relationship to Gruhle ("understanding psychology"), Jaspers ("The art of sympathising understanding") as well as Birnbaum ("pathographic methodology") becomes evident.

    Full Text Available Traditional roofing systems in the developing country likes Indonesia are still be dominated by the 30o, 45o, and more pitched angle roofs; the roofing cover materials are widely used to traditional clay roof tiles, then modern concrete roof tiles, and ceramic roof tiles. In the 90’s decay, shop houses are prosperous built with flat concrete roofs dominant. Green roofs and roof ponds are almost rarely built to meet the sustainable environmental issues. Some tested various roof systems in Surabaya were carried out to observe the roof thermal performances. Mathematical equation model from three references are also performed in order to compare with the real project tested. Calculated with equation (Kabre et al., the 30o pitched concrete-roof-tile, 30o clay-roof-tile, 45o pitched concrete-roof-tile are the worst thermal heat flux coming to room respectively. In contrast, the bare soil concrete roof and roof pond system are the least heat flux streamed onto room. Based on predicted calculation without insulation and cross-ventilation attic space, the roof pond and bare soil concrete roof (greenery roof are the appropriate roof systems for the Surabaya’s climate; meanwhile the most un-recommended roof is pitched 30o or 45o angle with concrete-roof tiles roofing systems.

    Full Text Available In this paper we analyze a group of Attic imports, found in the excavations of Cerro del Prado, a settlement situated in the Bahía de Algeciras (Cádiz. The great interest of this group lies in the fact that it belongs to a particular chronological period, the last third of the 5th century B.C., as we have not found later imports, and in the almost exclusive presence of black glazed vases, which gives US an idea of a very definitive demand of the punic society of the Iberian Peninsula regarding the trade of greek goods.

    Presentamos en este trabajo un conjunto de importaciones áticas halladas en las excavaciones del Cerro del Prado, situado en la bahía de Algeciras (Cádiz. El interés de este conjunto reside en su pertenencia a un momento cronológico muy concreto: el último tercio del siglo V a.C., no habiéndose hallado importaciones más modernas y en la presencia absoluta de vasos de barniz negro, lo que nos habla de una demanda muy determinada de la sociedad púnica peninsular frente al comercio de productos griegos.

  12. Effective use of Wikis in College Mathematics Classes

    Full Text Available Wikis are used in mathematics education in a variety of ways [3]. As with Wikipedia, mathematics related Wikis provide pages and links that describe many different branches of mathematics. Another common use is as a portal for distributing and collecting mathematics course materials [1]. This article describes the authors' use of course wikis for two different purposes in two undergraduate math courses. In Calculus-I, a wiki was utilized to share and present the outcome of an optimization problem that required small groups to collect information about student homes' attic insulation status and eventually to compute the optimal amount of new insulation to add that maximizes heating savings. The second wiki was for a small seminar-style course on Mathematical Mysteries where students collected and posted the results of their research relating to famous unsolved problems in mathematics. This wiki was also used as a platform for in-class presentations by the students and the instructors. In both cases, the bulk of the wiki contribution was by students.

    OBJECTIVE The anterior transpetrosal approach (ATPA) was established in 1984 and has been particularly effective for petroclival tumors. Although some complications associated with this approach, such as venous hemorrhage in the temporal lobe and nervous disturbances, have been resolved over the years, the incidence rate of CSF leaks has not greatly improved. In this study, some varieties of air cell tracts that are strongly related to CSF leaks are demonstrated. In addition, other pre- and postoperative risk factors for CSF leakage after ATPA are discussed. METHODS Preoperative and postoperative target imaging of the temporal bone was performed in a total of 117 patients who underwent ATPA, and various surgery-related parameters were analyzed. RESULTS The existence of air cells at the petrous apex, as well as fluid collection in the mastoid antrum detected by a postoperative CT scan, were possible risk factors for CSF leakage. Tracts that directly connected to the antrum from the squamous part of the temporal bone and petrous apex, rather than through numerous air cells, were significantly related to CSF leak and were defined as "direct tract." All patients with a refractory CSF leak possessed "unusual tracts" that connected to the attic, tympanic cavity, or eustachian tube, rather than through the mastoid antrum. CONCLUSIONS Preoperative assessment of petrous pneumatization types is necessary to prevent CSF leaks. Direct and unusual tracts are particularly strong risk factors for CSF leaks.

    The Centre Block of Canada's Parliament buildings, National Historic Site of Canada is set to undergo a major rehabilitation project that will take approximately 10 years to complete. In preparation for this work, Heritage Conservation Services (HCS) of Public Services and Procurement Canada has been completing heritage documentation of the entire site which includes laser scanning of all interior rooms and accessible confined spaces such as attics and other similar areas. Other documentation completed includes detailed photogrammetric documentation of rooms and areas of high heritage value. Some of these high heritage value spaces present certain challenges such as accessibility due to the height and the size of the spaces. Another challenge is the poor lighting conditions, requiring the use of flash or strobe lighting to either compliment or completely eliminate the available ambient lighting. All the spaces captured at this higher level of detail were also captured with laser scanning. This allowed the team to validate the information and conduct a quality review of the photogrammetric data. As a result of this exercise, the team realized that in most, if not all cases, the photogrammetric data was more detailed and at a higher quality then the terrestrial laser scanning data. The purpose and motivation of this paper is to present these findings, as well provide the advantages and disadvantages of the two methods and data sets.

    Triangular enclosures are typical configurations of attic spaces found in residential as well as industrial pitched-roof buildings. Natural convection in triangular rooftops has received considerable attention over the years, mainly on right-angled and isosceles enclosures. In this paper, a finite volume CFD package is employed to study the laminar air flow and temperature distribution in asymmetric rooftop-shaped triangular enclosures when heated isothermally from the base wall, for aspect ratios (AR) 0.2 ≤ AR ≤ 1.0, and Rayleigh number (Ra) values 8 × 10 5 ≤ Ra ≤ 5 × 10 7 . The effects of Rayleigh number and pitch angle on the flow structure and temperature distributions within the enclosure are analysed. Results indicate that, at low pitch angle, the heat transfer between the cold inclined and the hot base walls is very high, resulting in a multi-cellular flow structure. As the pitch angle increases, however, the number of cells reduces, and the total heat transfer rate progressively reduces, even if the Rayleigh number, being based on the enclosure height, rapidly increases. Physical reasons for the above effect are inspected

    This report presents the results of an assessment of the Sustainable Energy Resources for Consumers (SERC) grant program that was administered by the US Department of Energy Weatherization and Intergovernmental Program Office. Grants totaling $90 million were awarded to 101 local weatherization agencies located in 27 states. More than 15,000 housing units were touched by the SERC program. Close to 29,000 SERC technologies were installed and/or services delivered. The report summarizes the results of site visits to 27 agencies in which the following 14 technologies were observed: solar photovoltaic panels, solar hot water heaters, solar thermal air panels for space heating, tankless water heaters, heat pump water heaters, geothermal heat pumps, super-evaporative cooling systems, combination boilers and indirect water heaters, small-scale residential wind systems, cool roofs, masonry spray foam insulation, attic radiant barriers, mini-split heat pumps, and in-home energy monitors. The evaluation found that the national weatherization network is capable of installing and delivering a wide range of new and innovative technologies, but the usability and adoptability of some technologies may prove impractical for the weatherization network and the demographic for which it serves.

  17. The diet of wintering Barn Owls (Tyto alba in the region of Histria, the Danube Delta Biosphere Reserve

    SÁNDOR D. Attila

    2008-10-01

    Full Text Available The Barn Owl (Tyto alba is a common nocturnal predator of agro-ecosystems and it is widely distributed, especially in European countryside. The species uses human artifacts, ruins, barns, attics, towers for breeding and roosting, these sites can provide researchers with hundreds of pellets, thus its diet is well known. A first assessment of the diet and food selection was made for the southern part of the Danube Delta Biosphere Reserve in the wintering period, in a unique wetland-grassland complex, with large areas of steppes. Mammals dominated the diet spectrum, with the shrews (Soricidae being the most frequent (48.3%, followed by the mice (Muridae, and the voles (Arvicolinae. The mammalian component of the diet is important also in terms of biomass (97.8 %. The most valuable species is the Sibling Vole (Microtus epiroticus equalling 25.5 % of all biomass consumed, followed by the Common White-toothed Shrew (Crocidura suaveolens and the Mound-building Mouse (Mus spicilegus. Birds and amphibians made up a small portion of the diet, both in terms of occurrence and of biomass. Three species of birds were captured, the House Sparrow (Passer domesticus being the most important. The results suggest that the Barn Owl is a specialized feeder relying on small mammals and completing its diet with other prey only occasionally.

    Full Text Available Study carried out within the urban perimeter of Londrina, which is located in the North of the state of Paraná. The objectives were the identification of urban species of bats and diurnal roosts used by them and the verification of the problems they can cause to the population. The fire brigade, the Autarquia Municipal do Ambiente de Londrina (Municipal Environment Autarchy of Londrina, the Biology Department of the Universidade Estadual de Londrina (State University of Londrina and local residents helped spot the roosts. The collections were carried out in regular intervals between April 1998 and March 1999. By the end of them, 815 bats of 23 different species had been captured. Among these, 12 were found near or inside human constructions: Noctilio albiventris Desmarest, 1818; Artibeits lituratus (Olfers, 1818; Platyrrhinus lineatus (E. Geoffroy, 1810; Eptesicus brasiliensis Desmarest 1819; Lasiurus bore-alls (Muller 1776; Lasiurus ega (Gervais, 1856; Eumops glaucinus (Wagner, 1843; Molossus rufus (E. Geoffroy, 1805; Molossus molossus (Pallas, 1766; Nyctinomops laticaudatus (E. Geoffroy, 1805; Nyctinomops macrotis (Gray, 1840 e Tadarida brasiliensis (i. Geoffroy, 1824. Roost sites comprised expansion joints, roofs, attics and parks, among others. It can be concluded that bats are treated as undesirable animals by the population due to the lack of knowledge about the subject.

    Aich, Walid; Omri, Ahmed; Ben Nasrallah, Sassi

    2009-01-01

    This paper deals with a numerical simulation of natural convection flows in a prismatic cavity. This configuration represents solar energy collectors, conventional attic spaces of greenhouses and buildings with pitched roofs. The third dimension of the cavity is considered long enough for the flow to be considered 2D. The base is submitted to a uniform heat flux, the two top inclined walls are symmetrically cooled and the two vertical walls are assumed to be perfect thermal insulators. The aim of the study is to examine the thermal exchange by natural convection and effects of buoyancy forces on flow structure. The study provides useful information on the flow structure sensitivity to the governing parameters, the Rayleigh number (Ra) and the aspect ratio of the cavity. The hydrodynamic and thermal fields, the local Nusselt number, the temperature profile at the bottom and at the center of the cavity are investigated for a large range of Ra. The effect of the aspect ratio is examined for different values of Ra. Based on the authors knowledge, no previous results on natural convection in this geometry exist

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    Columbia County (New York) Habitat for Humanity built a pair of townhomes to Passive House criteria with the purpose of exploring approaches for achieving Passive House performance and to eventually develop a prototype design for future projects. The project utilized a 2x6 frame wall with a structural insulated panel curtain wall and a ventilated attic over a sealed OSB ceiling air barrier. Mechanical systems include a single head, wall mounted ductless mini-split heat pump in each unit and a heat recovery ventilator. Costs were $26,000 per unit higher for Passive House construction compared with the same home built to ENERGY STAR version 3 specifications, representing about 18 percent of total construction cost. This report discusses the cost components, energy modeling results and lessons from construction. Two alternative ventilation systems are analyzed: a central system; and, a point-source system with small through-wall units distributed throughout the house. The report includes a design and cost analysis of these two approaches.

    This article presents some miscellaneous data from two low-slope and two steep-slope experimental roofs. The low-slope roofs were designed to compare the performance of various roof coatings exposed to natural weatherization. The steep-slope roofs contained different combinations of phase change material, rigid insulation, low emittance surface and above-sheathing ventilation, with standing-seam metal panels on top. The steep-slope roofs were constructed on a series of adjacent attics separated at the gables using thick foam insulation. This article describes phase three (3) of a study that began in 2009 to evaluate the energy benefits of a sustainable re-roofing technology utilizing standing-seam metal roofing panels combined with energy efficient features like above-sheathing-ventilation (ASV), phase change material (PCM) and rigid insulation board. The data from phases 1 and 2 have been previously published and reported [Kosny et al., 2011; Biswas et al., 2011; Biswas and Childs, 2012; Kosny et al., 2012]. Based on previous data analyses and discussions within the research group, additional test roofs were installed in May 2012, to test new configurations and further investigate different components of the dynamic insulation systems. Some experimental data from phase 3 testing from May 2012 to December 2013 and some EnergyPlus modeling results have been reported in volumes 1 and 3, respectively, of the final report [Biswas et al., 2014; Biswas and Bhandari, 2014].

    Full Text Available Introduction: An otogenic brain abscess is a common ENT problem but an otogenic trapezius abscess can also be experienced in otolaryngological practice, particularly in patients with chronic suppurative otitis media.   Case Report: We report a rare case of a trapezius abscess in an eight-year-old girl who presented at the ENT, Head and Neck Surgery Postgraduate Medical Institute, Lady Reading Hospital, Peshawar, Pakistan on 15th December, 2010, with a presenting complaint of discharge from her right ear that had been occurring for the last five years. An exploration of the patient’s right ear was performed, which showed that there was extensive cholesteatoma and tissue granulation tissues the antrum, attic and middle ear. The trapezius abscess had spread down to her back and was repeatedly drained. The patient was discharged on the 14th day following admission after making a complete recovery. After a regular follow-up period the child has remained disease free. The rare nature of this case prompted us to write this report.   Conclusion: Chronic suppurative otitis media is a common clinical problem in developing countries. It can result in a number of complications if not treated properly. Although an otogenic trapezius abscess is a rare complication of chronic suppurative otitis media, it must be kept in mind.

    Full Text Available The double Perovskites materials with the formula A2 BB’O6 has been studied thoroughly in the past years due to its versatility, which allow to include the alkaline earth ions in A sites and transition metals in B and B’sites, giving origin to several physical properties with various industrials applications. In this work the structural and electronic properties of Ba2 InTaO6 are studied, material that is particularly interesting due to its possible application to the development of dielectric resonators and microwave signal filters on mobile phones and other wireless devices. Using ab-initio computational model, based on the Density Funtional Theory (DFT, and starting from spacial group Fm-3m, we calculate lattice parameters, equilibrium energies and equations of state among other quantities. The energy minimization as a function of volume allows to obtain a attice constant of 15.861 Bohr. The results of electronic density of states (DOS show that the double Perovskite Ba2 InTaO6 has an indirect gap of ~ 4.25 eV.

    Full Text Available The occurrence of dampness and mold in the indoor environment is associated with respiratory-related disease outcomes. Thus, it is pertinent to know the magnitude of such indoor environment problems to be able to estimate the potential health impact in the population. In the present study, the moisture damage in 10,112 Norwegian dwellings was recorded based on building inspection reports. The levels of moisture damage were graded based on a condition class (CC, where CC0 is immaculate and CC1 acceptable (actions not required, while CC2 and CC3 indicate increased levels of damage that requires action. Of the 10,112 dwellings investigated, 3125 had verified moisture or mold damage. This amounts to 31% of the surveyed dwellings. Of these, 27% had CC2 as the worst grade, whereas 4% had CC3 as the worst grade level. The room types and building structures most prone to moisture damage were (in rank order crawl spaces, basements, un-insulated attics, cooling rooms, and bathrooms. The high proportion of homes with moisture damage indicate a possible risk for respiratory diseases in a relatively large number of individuals, even if only the more extensive moisture damages and those located in rooms where occupants spend the majority of their time would have a significant influence on adverse health effects.

  6. Monstrous Domesticity – Home as a Site of Oppression in Crimson Peak

    Emilia Musap

    2017-12-01

    Full Text Available This paper begins by offering a brief overview of the popular culture narrative Crimson Peak (2015, directed by Guillermo del Toro. The analysis focuses on the most compelling Gothic trope del Toro reintroduces, the proverbial mansion, simultaneously displaying Freud’s heimlich and unheimlich elements, oppressing and liberating its inhabitants. Since the narrative revolves around two female protagonists, Lucille Sharpe and Edith Cushing, the paper also refers to feminist socio-cultural perspectives on space, primarily Gillian Rose’s and Shelley Mallett’s, in order to understand the position of the two protagonists within the decidedly Gothic space. This paper aims to emphasize that Lucille’s liberation as the mistress of the house is illusory regardless of the fact that she is represented as the embodiment of domestic corruption. It is precisely because she is a sexually active woman and a disruptor of the patriarchal order that she must ultimately be punished. Even though del Toro subverts the traditional image of the madwoman in the attic by positioning her at the center of the narrative, Allerdale Hall does not reveal itself as a space of female empowerment.

  7. Archaeometric investigation of red-figured pottery fragments from Gioiosa Guardia (Messina, Sicily) by INAA, FT-IR and TOF-ND techniques

    2008-01-01

    The present work is addressed to the study of some precious ancient pottery fragments, coming from the archaeological site of Gioiosa Guardia, in the Tirrenean Coast of Sicily. On the basis of historical and aesthetic considerations, the findings are dated back to 6.-5. Century b.C. and show a surface entirely decorated by red-figured technique, typical of Attic production. Many doubts arise about the real provenance of the artefacts. On one side, they could come directly from Greece, as attested by trading patterns between Greece and Southern Italy, on the other side, they could be produced in Sicily under the Greek artistic influence. In order to obtain a detailed characterization of the samples, a microdistruttive investigation was performed by Instrumental Neutron Activation Analysis (INAA), Fourier transform infrared absorption (FT-IR) and a non-invasive analysis by time-of-flight neutron diffraction (TOF-ND). Starting from the identification of the mineralogical and geochemical composition, a correct classification of the shards can be achieved.

    Ceramic specimens from the excavations of the Agora of ancient Athens, Greece, including material from factories, i.e., trial firing pieces, pottery and figurine wasters, datable to the Protogeometric, Subgeometric, and Classical Periods, and stylistically related figurines and pottery were analyzed by neutron activation. The factory material from the three distinct chronological periods separated respectively into three significantly different compositional groups, indicating either that separate sources of clay were used during each of these periods or that some other significant changes in the traditions of fabrication had occurred. Many of the figurines and sherds analyzed coincided in composition with one of these three groups and therefore were shown to be consistent with the output of Athenian workshops. Some specimens of Corinthian style formed a separate compositional group as did some other specimens that agreed in composition with a clay from Aegina. Comparison of these results with previous analyses on file in the Brookhaven Data Bank revealed a number of specimens that corresponded both in style and composition to the Agora material. Most significant was a sizable amount of Classical Greek pottery excavated in southern France, in Israel, and in Cyprus that conformed in composition to the Attic Classical Group. 6 figures, 2 tables

    2004-07-01

    A 3 year field study was conducted in which temperature, heat flow, reflectance and emittance field data were calculated for 12 different painted and unpainted metal roofs exposed to weathering at an outdoor test facility at Oak Ridge National Laboratory in Oakridge, Tennessee. In addition, the Florida Solar Energy Center tested several Habitat for Humanity homes during one summer in Fort Myers, Florida. The objective was to determine how cooling and heating energy loads in a building are affected by the solar reflectance and infrared emittance of metal roofs. The Habitat for Humanities houses had different roofing systems which reduced the attic heat gain. White reflective roofs were shown to reduce cooling energy needs by 18 to 26 per cent and peak demand by 28 to 35 per cent. High solar reflectance and high infrared emittance roofs incur surface temperatures that are about 3 degrees C warmer than the ambient air temperature. A dark absorptive roof exceeds the ambient air temperature by more than 40 degrees C. It hot climates, a high solar reflectance and high infrared emittance roof can reduce the air conditioning load and reduce peak energy demands on the utility. It was concluded that an informed decision of the roof surface properties of reflectance and emittance can significantly reduce energy costs for homeowners and builders in hot climates. 7 refs., 2 tabs., 7 figs.

    2014-04-01

    This measure guideline covers how to assess and carry out the combustion safety procedures for appliances and heating equipment that uses indoor air for combustion in low-rise residential buildings. Only appliances installed in the living space, or in an area freely communicating with the living space, vented alone or in tandem with another appliance are considered here. A separate measure guideline addresses combustion appliances located either within the living space in enclosed closets or side rooms or outside the living space in an adjacent area like an attic or garage that use outdoor air for combustion. This document is for inspectors, auditors, and technicians working in homes where energy upgrades are being conducted whether or not air infiltration control is included in the package of measures being applied. In the indoor combustion air case, guidelines summarized here are based on language provided in several of the codes to establish minimum requirements for the space using simplified prescriptive measures. In addition, building performance testing procedures are provided by testing agencies. The codes in combination with the test procedures offer comprehensive combustion safety coverage to address safety concerns, allowing inexperienced residential energy retrofit inspectors to effectively address combustion safety issues and allow energy retrofits to proceed.

  12. Modification of radon levels in homes

    International Nuclear Information System (INIS)

    Breysse, P.A.

    1987-01-01

    Radon infiltration from the ground into a house is primarily due to pressure differences between the interior of the home and the soil. If the atmospheric pressure inside the home is lower than the pressure in the soil, flow into the house will be accelerated since air flows from high pressure to lower pressure. Pressure differences can arise due to wind action. Temperature differences between indoors and outdoors also affect the relative indoor and outdoor pressure. These temperature and pressure variations can produce a stack effect which sucks air in from the bottom of the structure where the interior pressure is lowered and out toward the top. The internal pressure in houses is usually less than the gas pressure in the soil. Internal pressure in houses, however, can be further lowered as the result of the operation of kitchen, bathroom and attic exhaust fans as well as by the use of fireplaces, furnaces and wood stoves, and clothes dryers. This further reduction in internal pressure will likely increase the entry of radon into the house

    Full Text Available In this research the author studies a series of problems related to the evolution of the groups *k(hi̭, *kṷ(hi̭, *t(hi̭ and *tṷ in Greek. After a brief description of the palatalization process undergone by these groups and considering the different results from *t(hi̭ in the Ionic-Attic and Arcadian-Cypriot dialects which were swept twice by a wave of palatalization as well as the possible influence by analogy of the development undergone by *k(hi̭, the author examines in great depth the state of these groups at the time of the Mycenaean tablets analyzing the different values proposed for the series z- and s-. For z- an occlusive palatal and for s- an affricate articulation are considered the most likely ones. The author further suggests that the s- series followed an evolution parallel to that of the complex syllabograms of the type raz, roz, etc. Subsequently the author analyzes the graphic issues related to the evolution of the phonemic groups under study: The use of a special graphical notation in some Ionic and Pamphylian σσ/ττ in the dialects during the first millennium are due to the influence derived from the graphic representation of the state *ts. Finally the author suggests the Boeotian dialect as a starting point for the change *ts > tt, as in this dialect tt has a corresponding voiced series dd.

    Full Text Available This paper refers to the dialectal state of Greece during the second millennium B. C. In a forthcoming issue of Emerita another article will follow on «The creation of the Greek dialects of the first millennium». According to the author Mycenaean, although closely related with the other Greek oriental dialects, would present features of its own: this dialect sometimes has innovations not found anywhere else, sometimes presents doublets while the other dialects choose one or the other form. The original kernel of Epic language is related to Mycenaean but differs from it both in archaisms and innovations. This language was altered in the beginning of the first millennium when some Homeric features were interpreted as Ionian or Aeolian and so allowed the introduction of actual Ionian and Aeolian features. On the other hand already in the second millennium might exist some varieties in the oriental Greek dialects which form the kernels of the future Ionian-Attic, Aeolian and Arcadian-Cypriot dialects. It is just these varieties which are called Para-Mycenaean by the author. It is quite trustworthy to believe that Crete was the birthplace of linear B, exported then to the Continent to be used by the official recorders. Epic Achaean language, on the contrary, is believed to be born in the Continent and to have developed in Minor Asia.

    Twenty-eight patients with cholesteatoma were studied preoperatively by means of CT petrous bone to determine the localization and extension of their lesion. All the patients underwent survey and the intraoperative findings were compared with those resulting from CT. The reading was carried out with no knowledge of the intraoperative data. The following results were obtained: localization of cholesteatoma in attic, antrum and posterior tympanic cavity had a sensitivity of 0.91 and a specificity of 0.57, with a Fisher's p value less than 0.0005. When the erosion produced by the cholesteatoma was studied in the different structures, the accuracy was greatest with the stape, the septum and prussak's space; the highest number of false negatives corresponded to the tympanic membrane. The false positives were produced in the assessment of the facial canal, tegmen tympani and the labyrinthine fistula. The reliability of CT was very high for the diagnosis of ossicular destruction and displacement of the small bones, as well as for the state of the mastoid cells and congenital variations. In conclusion, we point out the importance of performing a CT study prior to surgery for cholesteatoma due to its elevated sensitivity in locating the lesion, and we stress the value of the knowledge of the erosion of the different structures since it constitutes a guide for intraoperative exploration and assessment.

    High resolution CT has become an important tool of radiographic assessment of the temporal bone. This study was undertaken to establish criteria for spatial relationship of the ossicles on axial projection. Normal CT of the fifty-seven temporal bones was reviewed. All parts of the malleus and incus were identified in all cases, while the head, the anterior crus and the posterior crus of the stapes were identified in 68.4 % (39/57), 5.3 % (3/57), 3.5 % (2/57), respectively. In none of the cases was the footplate of the stapes seen. The malleus manubrium and the incus long process aligned almost parallel to each other with being 28.0 0 (S.D. 6.5 0 ) and 26.9 0 (S.D. 5.7 0 ) to the coronal plane, respectively. The malleus head and the incus body and short process lied within the attic on the 28.0 0 (S.D. 3.9 0 ) angle to the sagittal plane. With the above-mentioned knowledge of the normal spatial alignment of the ossicles, one is able to detect subtle malalignment of the ossicular chain on axial CT alone. However, it should be kept in mind that coronal CT would usually be necessary to evaluate the incudostapedial joint as well as the stapes itself. Pathologic cases involving the ossicles were illustrated. (author)

  17. Norwegian Pitched Roof Defects

    2016-06-01

    Full Text Available The building constructions investigated in this work are pitched wooden roofs with exterior vertical drainpipes and wooden load-bearing system. The aim of this research is to further investigate the building defects of pitched wooden roofs and obtain an overview of typical roof defects. The work involves an analysis of the building defect archive from the research institute SINTEF Building and Infrastructure. The findings from the SINTEF archive show that moisture is a dominant exposure factor, especially in roof constructions. In pitched wooden roofs, more than half of the defects are caused by deficiencies in design, materials, or workmanship, where these deficiencies allow moisture from precipitation or indoor moisture into the structure. Hence, it is important to increase the focus on robust and durable solutions to avoid defects both from exterior and interior moisture sources in pitched wooden roofs. Proper design of interior ventilation and vapour retarders seem to be the main ways to control entry from interior moisture sources into attic and roof spaces.

    Sixteen apartments serving low-income populations in three buildings were retrofit with the goal of simultaneously reducing energy consumption and improving indoor environmental quality (IEQ). Retrofit measures varied among apartments and included, among others, envelope sealing, installation of continuous mechanical ventilation systems, upgrading bathroom fans and range hoods, attic insulation, replacement of heating and cooling systems, and adding wall-mounted particle air cleaners. IEQ parameters were measured, generally for two one-week periods before and after the retrofits. The measurements indicate an overall improvement in IEQ conditions after the retrofits. Comfort conditions, bathroom humidity, and concentrations of carbon dioxide, acetaldehyde, volatile organic compounds, and particles generally improved. Formaldehyde and nitrogen dioxide levels decreased in the building with the highest concentrations, were unchanged in a second building, and increased in a third building. IEQ parameters other than particles improved more in apartments with continuous mechanical ventilation systems installed. In general, but not consistently, larger percent increases in air exchange rates were associated with larger percent decreases in indoor levels of the pollutants that primarily come from indoor sources.

    Duct thermal losses and air leakage have long been recognized as prime culprits in the degradation of heating, ventilating, and air-conditioning (HVAC) system efficiency. Both the U.S. Department of Energy’s Zero Energy Ready Home program and California’s proposed 2016 Title 24 Residential Energy Efficiency Standards require that ducts be installed within conditioned space or that other measures be taken to provide similar improvements in delivery effectiveness (DE). Pacific Gas & Electric Company commissioned a study to evaluate ducts in conditioned space and high-performance attics (HPAs) in support of the proposed codes and standards enhancements included in California’s 2016 Title 24 Residential Energy Efficiency Standards. The goal was to work with a select group of builders to design and install high-performance duct (HPD) systems, such as ducts in conditioned space (DCS), in one or more of their homes and to obtain test data to verify the improvement in DE compared to standard practice. Davis Energy Group (DEG) helped select the builders and led a team that provided information about HPD strategies to them. DEG also observed the construction process, completed testing, and collected cost data.

    The report concerns a married couple who were repeatedly invaded by pigeon fleas (Ceratophyllus columbae) over a period of 2 months. The source of the fleas was a pair of breeding feral pigeons (Columba livia). The birds' nest was located in the attic immediately above the couple's apartment, and the fleas found their way along an unsealed heating pipe. The people encountered up to 40 bites per night. With invasions repeated almost every night, the man gradually developed an allergic urticarial reaction. The most traumatic experience for the couple, however, was to learn that they were invaded by fleas (initially, they had presumed they were bothered by mosquitoes). This information resulted in severe psychological distress with phobic reactions and insomnia. Despite the successful removal of the fleas and the pigeons that were source of the pest, parasitophobia of the man persisted over the following 4 months. This case is discussed from the broader aspect of health risks related to feral pigeons and animal fleas. Also summarised are previous observations on people invaded by pigeon fleas.

    The dispersal flights of West Indian drywood termite, Cryptotermes brevis (Walker) (Isoptera: Kalotermitidae) were surveyed in the major cities of Azores. The sampling device used to estimate termite density consisted of a yellow adhesive trap (size 45 by 24 cm), placed with an artificial or natural light source in a dark attic environment. In addition, data from two other projects were used to improve the knowledge about the geographical distribution of the species. The level of infestation in the two main Azorean towns differed, with high levels in the houses of Angra do Heroísmo, whereas in Ponta Delgada, there are fewer houses with high levels of infestation. The infestation in Ponta Delgada shows a pattern of spreading from the center outward to the city's periphery, whereas in Angra do Heroísmo, there was a pattern of spreading outward from several foci. The heavy infestation observed in Angra do Heroísmo and the clear increase of infestation levels observed from 2010 to 2011 is a reason for concern and calls for an urgent application of an Integrated Pest Management (IPM) control strategy. © The Author 2014.

    Two red-figured vases, kindly provided by the Carabinieri Corps for Protection of Cultural Heritage, Cosenza Unit (Calabria, Italy), were characterised from petrographical, morphological, mineralogical, and chemical viewpoints with the aim of establishing the definite origin and source area of archaeological artefacts. It was obvious that one of the vases had undergone restoration, which is not documented. On the basis of stylistic criteria, it was not possible to assign precisely the site of production of the figured vases. Petrographic analysis, scanning electron microscopy (SEM), and X-ray diffraction (XRD) studies were carried out with the aim of identifying technological features and defining the nature of coatings. Fourier transform infrared spectroscopy (FT-IR) revealed that some protective products had been used in previous restoration processes on some portions of one of the two finds. The samples have similar features: fine texture of the ceramic body, and black gloss painted directly on it. One of the samples is characterised by the black coating typical of both Attic and Locrian pottery. A study of their composition excluded the possibility that they are of Greek production. Inductively coupled plasma mass spectrometry (ICP-MS) data revealed that they come exclusively from the Locride area in Calabria, Southern Italy.

    The Stockton house retrofit is a two-story Tudor style single family deep retrofit in the hot-dry climate of Stockton, CA. The home is representative of a deep retrofit option of the scaled home energy upgrade packages offered to targeted neighborhoods under the pilot Large-Scale Retrofit Program (LSRP) administered by the Alliance for Residential Building Innovation (ARBI). Deep retrofit packages expand on the standard package by adding HVAC, water heater and window upgrades to the ducting, attic and floor insulation, domestic hot water insulation, envelope sealing, lighting and ventilation upgrades. Site energy savings with the deep retrofit were 23% compared to the pre-retrofit case, and 15% higher than the savings estimated for the standard retrofit package. Energy savings were largely a result of the water heater upgrade, and a combination of the envelope sealing, insulation and HVAC upgrade. The HVAC system was of higher efficiency than the building code standard. Overall the financed retrofit would have been more cost effective had a less expensive HVAC system been selected and barriers to wall insulation remedied. The homeowner experienced improved comfort throughout the monitored period and was satisfied with the resulting utility bill savings.

    Columbia County (New York) Habitat for Humanity built a pair of townhomes to Passive House criteria with the purpose of exploring approaches for achieving Passive House performance and to eventually develop a prototype design for future projects. The project utilized a 2x6 frame wall with a structural insulated panel curtain wall and a ventilated attic over a sealed OSB ceiling air barrier. Mechanical systems include a single head, wall mounted ductless mini-split heat pump in each unit and a heat recovery ventilator. Costs were $26,000 per unit higher for Passive House construction compared with the same home built to ENERGY STAR version 3 specifications, representing about 18% of total construction cost. This report discusses the cost components, energy modeling results and lessons from construction. Two alternative ventilation systems are analyzed: a central system; and, a point-source system with small through-wall units distributed throughout the house. The report includes a design and cost analysis of these two approaches.

    The building which is the object of the study is located in the center of Andlau, France. This mansion that was built in 1582 was the residence of the Lords of Andlau from the XVIth century until the French Revolution. Its architecture represents the Renaissance style of the XVIth century in particular by its volutes and its spiral staircase inside the polygonal turret. In January 2005, the municipality of Andlau became the owner of this Seigneury which is intended to welcome the future Heritage Interpretation Center (HIC), a museum is also going to be created there. Three levels of attic of this building are going to be restored and isolated, the historic framework will that way be masked and the last three levels will not be accessible any more. In this context, our lab was asked to model the framework to allow to make diagnoses there, to learn to know and to consolidate the knowledge on this type of historic framework. Finally, next to a virtual visualization, we provided other applications in particular the creation of an accurate 3D model of the framework for animations, as well as for foundation of an historical information system and for supplying the future museum and HIC with digital data. The project contains different phases: the data acquisition, the model creation and data structuring, the creation of an interactive model and the integration in a historic information system. All levels of the attic were acquired: a 3D Trimble GX scanner and partially a Trimble CX scanner were used in particular for the acquisition of data in the highest part of the framework. The various scans were directly georeferenced in the field thanks to control points, then merged together in an unique point cloud covering the whole structure. Several panoramic photos were also realized to create a virtual tour of the framework and the surroundings of the Seigneury. The purpose of the project was to supply a 3D model allowing the creation of scenographies and interactive

    The experience acquired as a result of the operation of the Marcoule reactors and of the construction and start-up of the E.D.F. reactors on the one hand, and the conclusions of research and tests carried out out-of-pile on the other hand, lead to a considerable change in the general design of reactors of the gas-graphite type. The main modifications envisaged are analysed in the paper. The adoption of an annular fuel element and of a down-current cooling will make it possible to increase considerably the specific power and the power output of each channel; as a result there will be a considerable reduction in the number of the channels and a corresponding increase in the size of the unit cell. The graphite stack will have to be adapted to there new conditions. For security reasons, the use of prestressed concrete for the construction of the reactor vessel is becoming more widespread; they could lead to the exchangers and the fuel-handling apparatus becoming integrated inside the vessel (the so-called 'attic' device). A full-size mode) of this attic has been built at Saclay with the participation of EURATOM; the operational results obtained are presented as well as a new original design for the control rods. As for as the gas-heavy-water system is concerned, the research is carried out on two points of design; the first, which retains the use of horizontal pressure tubes, takes into account the experience acquired during the construction of the EL 4 reactor of which it will constitute an extrapolation; the second, arising from the research carried out on the gas-graphite system, will use a pre-stressed concrete vessel for holding the pressure, the moderator being almost at the same pressure as the cooling fluid and the fuel being placed in vertical channels. The relative merits of these two variants are analysed in the present paper.

    Full Text Available The co-authors consider the design solution developed for a panel residence building, type series 1-115, and provide a description of the emergency destruction of structural elements of a 9-storey panel residence building of this type (built in 1979, following a gas explosion. The overall length of the building is 86.4 m; its width is 12 m. The structural system in this building represents a longitudinal wall. Its external longitudinal walls are wade of ceramsite concrete, while its interior walls are made of concrete. Its reinforced concrete hollow slabs rest on the longitudinal load-bearing walls. The transverse walls of staircases are made of concrete blocks. The strip foundation supports the load-bearing walls of the building. The epicenter of the explosion was located in the kitchen on the eighth floor of the building. The kitchen was immediately adjacent to the staircase of the building. Partial destruction of the building followed the gas explosion. Exterior walls of its eighth and ninth floors and the attic were destroyed. Panel buildings designed in pursuance of the longitudinal structural system are more vulnerable to explosive loads compared to buildings designed to the cross-wall structural system, where bearing slabs rest on three interior walls. Thus, all slabs rest on each of the three internal walls of the building on both sides. In the buildings designed to the longitudinal wall structural system, slabs rest on the two walls, one of which is external. The article is based on the report following the inspection of the technical condition of the building, undertaken subsequent to its emergency destruction.

  14. Defining asbestos: differences between the built and natural environments.

    Asbestos - while most think they know what this material is, few understand the current issues surrounding it. Few would also realize that asbestos is the form of a mineral, and even fewer would know that there are different types of asbestos, that not only had different industrial applications, but pose differing health risks when inhaled. Asbestos was in wide-spread use mid-last century in many consumer products, and no doubt saved thousands of lives, but by the latter part of last century concerns over its health risk caused its use to wane, to the point it was removed from many buildings. So in many ways the asbestos story was coming to an end in the 1990s, but two events in the USA - the vermiculite ore produced from Libby, Montana which contained amphibole asbestos and was used in a million homes in the USA as attic insulation and the concern for exposure to asbestos occurring in its natural setting in El Dorado Hills, California led to an increased concern of the potential for low-level environmental exposure to asbestos to the general public. The current dilemma we find ourselves in, especially in the USA, deals with the relationships between our knowledge of handling asbestos and an understanding of its risk potential in the built environment versus the natural environment. And one perfect metaphor for this is the term used by many non-geologists to differentiate asbestos in the built vs natural environment - 'naturally occurring asbestos'. Clearly a misstatement, but only one of many we must deal with as we struggle to understand the risk to humans of natural occurrences of asbestos. This paper will try and address some of these issues centering around those occurring in the USA.

    Karlsruhe is one of the hottest cities in Germany with a temperature record of 40.2°C in August 2003. In 2013, two hot weather periods with continuous heat warnings by the German Weather Service for 7 and 8 days occurred during the second half of July and first 10 days of August 2013, and in early August the temperatures in Karlsruhe almost reached again the record of 40.2°C. To understand how citizens experienced the heat and what strategies they used to cope with the heat, we conducted a questionnaire survey on subjective heat stress and coping strategies immediately after the hot weather period. Based on a holistic approach the questionnaire included questions on heat stress experience in different contexts of daily life, health impacts of the heat, coping measures, housing conditions, urban environment, living conditions, and socio-demographic characteristics. The responses of the 323 survey participants living and working in Karlsruhe show that they on average experienced the heat as rather stressful event, whereby the heat stress experienced at home was significant lower than heat stress experienced at work or in general. Regression analyses show that, among the factors included in the questionnaire, the health impairments suffered during the heat, the control belief and the coping measures implemented mainly determine heat stress experienced in general and at work. For the subjective heat stress at home, factors of the built urban environment such as heat loading of district, living in the attic or the ground floor, and heat protection elements of the inhabited building also played a role. At the same time, the way the respondents used different coping strategies in context of their daily activities and routines during heat suggests lessons to learn from this event how individual response to heat differs from responses to other types of natural hazards.

    2005-12-15

    A survey was conducted to gather information on energy use and the factors affecting energy use in households residing in houses and residential buildings with fewer than 5 storeys. Dwelling characteristics, usage of appliances, and energy efficiency and consumption data were collected. An overview of the main findings were presented in this summary and included details of thermal envelopes; residential heating, air-conditioning and ventilation; household appliances; hot water; lighting; and Energy Star systems and appliances. The survey covered over 11 million households in all 10 Canadian provinces. Data were collected through computer-assisted personal interviews with owners, renters, landlords and property managers. It was observed that the average heated area of a Canadian dwelling was 1321 square feet, and that dwellings constructed after 1979 were larger and more energy efficient than previous dwellings. The majority of households located west of Quebec used natural gas, whereas the majority of Quebec households used electricity. Households in the Atlantic region used both electricity and oil. Penetration rates for high efficiency furnaces using natural gas, propane or oil furnaces was 62 per cent among dwellings built between 1990-2003. It was noted that more basements, attics, crawlspaces and garages are now being insulated. An increasing number of households use both a main and a secondary refrigerator. Nearly 25 per cent of households used 3 or more televisions. The use of central and window/room air-conditioners has increased, with Ontario households accounting for more than 60 per cent of all air-conditioning systems. Nearly 25 per cent of light bulbs were energy-efficient bulbs. It was also observed that Energy Star products have had a high penetration since the inception of the Energy Star initiative. However, a significant number of households were not aware if their products were Energy Star qualified. tabs., figs.

Its goals and accomplishments are described in this annual progress report for FY1993. Energy Division is committed to (1) understanding the mechanisms by which societies make choices in energy use; (2) improving society's understanding of the environmental, social, and economic implications of technological change; (3) developing and transferring energy-efficient technologies; (4) improving transportation policy and planning; (5) enhancing basic knowledge in the social sciences as related to energy and associated issues. Energy Division's expenditures in FY1993 totaled $42 million. The work was supported by the US DOE, DOD, many other federal agencies, and some private organizations. Disciplines of the 126.5 technical staff members include engineering, social sciences, physical and life sciences, and computer sciences and data systems. The division's programmatic activities cover three main areas: (1) analysis and assessment, (2) energy use and delivery technologies, and (3) transportation systems. Analysis and assessment activities involve energy and resource analysis, preparation of environmental assessments and impact statements, research on emergency preparedness, transportation analysis, and analysis of energy and environmental needs in developing countries. Energy use and delivery technologies focus on electric power systems, building equipment, building envelopes (walls, foundations, roofs, attics, and materials), and methods to improve energy efficiency in existing buildings. Transportation systems research is conducted both to improve the quality of civilian transportation and for sponsors within the US military to improve the efficiency of deployment, scheduling, and transportation coordination

    Gene duplication followed by functional divergence in the event of polyploidization is a major contributor to evolutionary novelties. The Brassica genus evolved from a common ancestor after whole-genome triplication. Here, we studied the evolutionary and functional features of Brassica spp. homologs to Tic40 (for translocon at the inner membrane of chloroplasts with 40 kDa). Four Tic40 loci were identified in allotetraploid Brassica napus and two loci in each of three basic diploid Brassica spp. Although these Tic40 homologs share high sequence identities and similar expression patterns, they exhibit altered functional features. Complementation assays conducted on Arabidopsis thaliana tic40 and the B. napus male-sterile line 7365A suggested that all Brassica spp. Tic40 homologs retain an ancestral function similar to that of AtTic40, whereas BolC9.Tic40 in Brassica oleracea and its ortholog in B. napus, BnaC9.Tic40, in addition, evolved a novel function that can rescue the fertility of 7365A. A homologous chromosomal rearrangement placed bnac9.tic40 originating from the A genome (BraA10.Tic40) as an allele of BnaC9.Tic40 in the C genome, resulting in phenotypic variation for male sterility in the B. napus near-isogenic two-type line 7365AB. Assessment of the complementation activity of chimeric B. napus Tic40 domain-swapping constructs in 7365A suggested that amino acid replacements in the carboxyl terminus of BnaC9.Tic40 cause this functional divergence. The distribution of these amino acid replacements in 59 diverse Brassica spp. accessions demonstrated that the neofunctionalization of Tic40 is restricted to B. oleracea and its derivatives and thus occurred after the divergence of the Brassica spp. A, B, and C genomes.

    Gwichyaa Zhee Gwich’in Tribal Government (GZGTG) applied for funding in 2014 under the U.S. Department of Energy Office of Indian Energy Deployment of Clean Energy on Tribal Lands funding opportunity. They were awarded 50% of the project costs for the construction of an 18kW, grid-tied solar PV array on the fort Yukon Tribal Hall, the construction of a 3kW solar PV array on the tribally owned greenhouse, the replacement of inefficient florescent lighting fixtures in the tribal hall to higher efficiency LED lights and the addition of blow in cellulose insulation to the attic of the tribal hall to assist with heat retention. Total DOE Funding for the project was $124,735. Total GZGTG funding for the project was $133,321 for a total project cost of $258,056. The Project was completed with 100% local labor on the tribal hall solar PV installation, the LED lighting retrofit and the insulation on the tribal hall. Based on the results at the tribal hall/office, the tribe also used their own tribal funding to retrofit the lighting in the community hall from florescent to LED lights. The resulting project was completed by the end of Sept 2016 and results have shown a decrease in fuel used at the tribal hall/office of 35% and a decrease in electric costs at the tribal hall of 68%. The total energy costs before the project were approximately $28,000 a year and the energy equivalent of 385 MMBTU/yr. After the project the total energy costs decreased to $11,200/yr. and an energy equivalent of only 242 MMBTU. This represents an overall decrease in energy use of 38%. All in all the tribe and the community regard this project as a huge success!

    2016-12-01

    Heat transfer to slab foundations has remained an area of building science with poor understanding over the last three decades of energy efficiency research. This is somewhat surprising since the area of floors in single family homes is generally equal to wall, or windows or attics which have been extensively evaluated. Research that has been done has focused in the impact of slab on grade foundations and insulation schemes on heat losses associated with heating in predominantly heating dominated climates. Slab on grade construction is very popular in cooling-dominated southern states where it accounts for 77 percent of new home floors according to U.S. Census data in 2014. There is a widespread conception that tile flooring, as opposed to carpet, makes for a cooler home interior in warm climates. Empirical research is needed as building energy simulations such as DOE-2 and EnergyPlus rely on simplified models to evaluate these influences. BA-PIRC performed experiments over an entire year from 2014-2015 in FSEC's Flexible Residential Test Facilities (FRTF) intended to assess for the first time 1) slab on grade influence in a cooling dominated climate, and 2) how the difference in a carpeted vs. uncarpeted building might influence heating and cooling. Two identical side by side residential buildings were evaluated, the East with pad and carpet and the west with a bare slab floor. A highly detailed grid of temperature measurements were taken on the slab surface at various locations as well as at depths of 1, 2.5, 5, 10 and 20 feet.

    Full Text Available Between 1995 and 2017 we carried out surveys on the Little Owl (Athene noctua in Battonya town and Kevermes village in southern Békés county. In 2007 and 2017 we have surveyed nesting sites in the village and the outer areas of Kevermes. The population of the species was estimated at the beginning of the breeding season and in early summer with field observations. Between 1995 and 2017 we collected road-kill data within the entire administrative area of Battonya. We registered each fiund road-killed Little Owl. We found 64 road-kills in Battonya. The number of casualties of the species has increased unambiguously over the studied 23 years. Most of the road-killed Little Owls (53 individuals, 82.81% of the total were found in summer (June–August. 51 road-killed individuals (79.69% were noted in the outer areas of Battonya, and 13 specimens (20.31% in the town. Our results highlight that vehicle traffic is an important mortality factor for the population. The Little Owl has a large population in this landscape, and the population size has increased over the last decade. In the background of this increase is most likely the rise in the number of abandoned houses because of the unfavourable economic and social situation in the region. The local pairs nested only on attics and roof structures in Kevermes, often in residential buildings. The buildings of modern agriculture do not meet the needs of the species. A large part of the population breeds in the village, because with the disappearance of the farms the breeding pairs of the outer areas of Kevermes have disappeared. However, in Battonya the species regularly breeds in the outer areas of the town. Finally, we also collected some ethnoecological data on how local people relate to the species.

  7. Building America Case Study: Accelerating the Delivery of Home-Performance Upgrades Using a Synergistic Business Model, Minneapolis, Minnesota

    Energy Technology Data Exchange (ETDEWEB)

    2016-04-01

    Achieving Building America energy savings goals (40 percent by 2030) will require many existing homes to install energy upgrades. Engaging large numbers of homeowners in building science-guided upgrades during a single remodeling event has been difficult for a number of reasons. Performance upgrades in existing homes tend to occur over multiple years and usually result from component failures (furnace failure) and weather damage (ice dams, roofing, siding). This research attempted to: A) Understand the homeowner's motivations regarding investing in building science based performance upgrades. B) Determining a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks. C) Access a business model that will manage all aspects of the contractor-homeowner-performance professional interface to ensure good upgrade decisions over time. The solution results from a synergistic approach utilizing networks of suppliers merging with networks of homeowner customers. Companies in the $400 to $800 billion home services industry have proven direct marketing and sales proficiencies that have led to the development of vast customer networks. Companies such as pest control, lawn care, and security have nurtured these networks by successfully addressing the ongoing needs of homes. This long-term access to customers and trust established with consistent delivery has also provided opportunities for home service providers to grow by successfully introducing new products and services like attic insulation and air sealing. The most important component for success is a business model that will facilitate and manage the process. The team analyzes a group that developed a working model.

  8. The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: Final Report

    Hughes, P.J.; Shonder, J.A.

    1998-03-01

    This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

    In January 1944 the Norwegian Resistance Movement placed a radio transmitter in the attic of the Department of Obstetrics and Gynaecology, the National Hospital (Rikshospitalet), Oslo. Knut Haugland (1917-2009) used this to send messages to the Norwegian government-in-exile in London. The transmitter was discovered by the Gestapo, and German troops surrounded the building on 1 April 1944. Haugland survived a dramatic escape. While the transmitter was in operation, Haugland lived with senior registrar Finn Bøe (1906-70) and his family in a hospital apartment. Bøe risked his own life and that of his family to assist during a dramatic phase of the resistance struggle. Bøe had completed a focused and purposeful clinical and academic training when he was appointed senior registrar at the Department of Obstetrics and Gynaecology, the National Hospital, in 1943. He was professionally ambitious. His thesis from 1938 was disqualified, but four years later he submitted a new, experimental thesis which he successfully defended in 1945. In 1955, Bøe became the first senior consultant at the Department of Obstetrics and Gynaecology at Aker hospital. Under his leadership, it became the largest in the Oslo area, and one of the most active in Norway with regard to science. Several of Bøe's own academic works on placental morphology and blood circulation have become classics. Outside of medicine, his great interest was music, and not only as a piano player. He also wrote a book about his fellow townsman Edvard Grieg.

  10. Suncatcher and cool pool. Project report

    Hammond, J.

    The Suncatcher is a simple, conical solar concentrating device that captures light entering clerestory windows and directs it onto thermal storage elements at the back of a south facing living space. The cone shape and inclination are designed to capture low angle winter sunlight and to reflect away higher angle summer sunlight. It is found that winter radiation through a Suncatcher window is 40 to 50% higher than through an ordinary window, and that the average solar fraction is 59%. Water-filled steal culvert pipes used for thermal storage are found to undergo less stratification, and thus to be more effective, when located where sunlight strikes the bottom rather than the top. Five Suncatcher buildings are described. Designs are considered for 32/sup 0/, 40/sup 0/ and 48/sup 0/ north latitude, and as the latitude increases, the inclination angle of the cone should be lowered. The Cool Pool is an evaporating, shaded roof pond which thermosiphons cool water into water-filled columns within a building. Preliminary experiments indicate that the best shade design has unimpeded north sky view, good ventilation, complete summer shading, a low architectural profile, and low cost attic vent lowers work. Another series of experiments established the satisfactory performance of the Cool Pool on a test building using four water-filled cylinders, two cylinders, and two cylinders connected to the Cool Pool through a heat exchanger. Although an unshaded pool cools better at night than a shaded one, daytime heat gain far offsets this advantage. A vinyl waterbag heat exchanger was developed for use with the Cool Pool. (LEW)

    IBACOS, in collaboration with GreenHomes America, was contracted by the New York State Energy Research and Development Authority to research exterior wall insulation solutions. This research investigated cost-effective deep energy retrofit (DER) solutions for improving the building shell exterior while achieving a cost-reduction goal, including reduced labor costs to reach a 50/50 split between material and labor. The strategies included exterior wall insulation plus energy upgrades as needed in the attic, mechanical and ventilation systems, and basement band joist, walls, and floors. The work can be integrated with other home improvements such as siding or window replacement. This strategy minimizes physical connections to existing wall studs, encapsulates existing siding materials (including lead paint) with spray foam, and creates a vented rain screen assembly to promote drying. GreenHomes America applied construction details created by IBACOS to a test home. 2x4 framing members were attached to the wall at band joists and top plates using 'L' clips, with spray foam insulating the wall after framing was installed. Windows were installed simultaneously with the framing, including extension jambs. The use of clips in specific areas provided the best strength potential, and 'picture framing' the spray foam held the 2x4s in place. Short-term testing was performed at this house, with monitoring equipment installed for long-term testing. Testing measurements will be provided in a later report, as well as utility impact (before and after), costs (labor and materials), construction time, standard specifications, and analysis for the exterior wall insulation strategy.

  13. Building America Case Study: Field Testing an Unvented Roof with Fibrous Insulation and Tiles, Orlando, Florida

    Energy Technology Data Exchange (ETDEWEB)

    2015-11-01

    This research is a test implementation of an unvented tile roof assembly in a hot-humid climate (Orlando, FL; Zone 2A), insulated with air permeable insulation (netted and blown fiberglass). Given the localized moisture accumulation and failures seen in previous unvented roof field work, it was theorized that a 'diffusion vent' (water vapor open, but air barrier 'closed') at the highest points in the roof assembly might allow for the wintertime release of moisture, to safe levels. The 'diffusion vent' is an open slot at the ridge and hips, covered with a water-resistant but vapor open (500+ perm) air barrier membrane. As a control comparison, one portion of the roof was constructed as a typical unvented roof (self-adhered membrane at ridge). The data collected to date indicate that the diffusion vent roof shows greater moisture safety than the conventional, unvented roof design. The unvented roof had extended winter periods of 95-100% RH, and wafer (wood surrogate RH sensor) measurements indicating possible condensation; high moisture levels were concentrated at the roof ridge. In contrast, the diffusion vent roofs had drier conditions, with most peak MCs (sheathing) below 20%. In the spring, as outdoor temperatures warmed, all roofs dried well into the safe range (10% MC or less). Some roof-wall interfaces showed moderately high MCs; this might be due to moisture accumulation at the highest point in the lower attic, and/or shading of the roof by the adjacent second story. Monitoring will be continued at least through spring 2016 (another winter and spring).

    Using automated and standardized computer tools to calculate the pertinent test result values has several advantages such as: 1. allowing high-fidelity solutions to complex nonlinear phenomena that would be impractical to express in written equation form, 2. eliminating errors associated with the interpretation and programing of analysis procedures from the text of test standards, 3. lessening the need for expertise in the areas of solid mechanics, fracture mechanics, numerical methods, and/or finite element modeling, to achieve sound results, 4. and providing one computer tool and/or one set of solutions for all users for a more "standardized" answer. In summary, this approach allows a non-expert with rudimentary training to get the best practical solution based on the latest understanding with minimum difficulty.Other existing ASTM standards that cover complicated phenomena use standard computer programs: 1. ASTM C1340/C1340M-10- Standard Practice for Estimation of Heat Gain or Loss Through Ceilings Under Attics Containing Radiant Barriers by Use of a Computer Program 2. ASTM F 2815 - Standard Practice for Chemical Permeation through Protective Clothing Materials: Testing Data Analysis by Use of a Computer Program 3. ASTM E2807 - Standard Specification for 3D Imaging Data Exchange, Version 1.0 The verification, validation, and round-robin processes required of a computer tool closely parallel the methods that are used to ensure the solution validity for equations included in test standard. The use of automated analysis tools allows the creation and practical implementation of advanced fracture mechanics test standards that capture the physics of a nonlinear fracture mechanics problem without adding undue burden or expense to the user. The presented approach forms a bridge between the equation-based fracture testing standards of today and the next generation of standards solving complex problems through analysis automation.

  15. Public Health Benefits of End-Use Electrical Energy Efficiency in California: An Exploratory Study

    McKone, Thomas E.; Lobscheid, A.B.

    2006-06-01

    This study assesses for California how increasing end-use electrical energy efficiency from installing residential insulation impacts exposures and disease burden from power-plant pollutant emissions. Installation of fiberglass attic insulation in the nearly 3 million electricity-heated homes throughout California is used as a case study. The pollutants nitrous oxides (NO{sub x}), sulfur dioxide (SO{sub 2}), fine particulate matter (PM2.5), benzo(a)pyrene, benzene, and naphthalene are selected for the assessment. Exposure is characterized separately for rural and urban environments using the CalTOX model, which is a key input to the US Environmental Protection Agency (EPA) Tool for the Reduction and Assessment of Chemicals and other environmental Impacts (TRACI). The output of CalTOX provides for urban and rural populations emissions-to-intake factors, which are expressed as an individual intake fraction (iFi). The typical iFi from power plant emissions are on the order of 10{sup -13} (g intake per g emitted) in urban and rural regions. The cumulative (rural and urban) product of emissions, population, and iFi is combined with toxic effects factors to determine human damage factors (HDFs). HDF are expressed as disability adjusted life years (DALYs) per kilogram pollutant emitted. The HDF approach is applied to the insulation case study. Upgrading existing residential insulation to US Department of Energy (DOE) recommended levels eliminates over the assmned 50-year lifetime of the insulation an estimated 1000 DALYs from power-plant emissions per million tonne (Mt) of insulation installed, mostly from the elimination of PM2.5 emissions. In comparison, the estimated burden from the manufacture of this insulation in DALYs per Mt is roughly four orders of magnitude lower than that avoided.

    samples for each day of CI activities were collected from the installer and hopper operator. Bulk CI samples were collected and analyzed for metal, boron, and sulfate content. Real-time and video exposure monitoring was conducted to further characterize the CI dust and workers' exposures. The exposure assessment also included a medical component. Investigators collected 175 personal breathing zone (PBZ) total dust, 106 area total dust, and 90 area respirable dust air samples during CI-related activities at the 10 contractor sites. Twenty-six employees' total dust 8-hour time-weighted averages (TWAs) exceeded the Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) of 15 mg/m3, and 42 exceeded the American Conference of Governmental Industrial Hygienists (ACGIH) threshold-limit value (TLV) of 10 mg/m3. Respirable dust air sampling and real-time monitoring with particle size discrimination indicated low levels of respirable dust generation. The SEM analyses revealed that fibers were an average 28 mum in length and ranged from 5 mum to 150 mum. CI installers' PBZ total dust, area total dust, and area respirable dust air samples were all significantly higher during dry attic applications than wet attic applications (Papplications than dry wall and ceiling applications (P=0.02). Analyses of variance tests revealed that exposure concentrations in total dust air samples collected in the PBZ of all CI workers, including installers working in attics, installers during wall applications, hopper operators during attic applications, and hopper operators during wall and ceiling applications, varied significantly during dry applications (Papplications, and hopper areas during wall and ceiling applications also differed significantly during dry applications (P=0.03). Twenty-three workers participated in the medical phase of the investigation. The workers completed medical and work history questionnaires, performed serial peak flow tests, and completed

    This multi-faceted study evaluated several aspects of uncontrolled air flows in commercial buildings in both Northern and Southern climates. Field data were collected from 25 small commercial buildings in New York State to understand baseline conditions for Northern buildings. Laboratory wall assembly testing was completed at Syracuse University to understand the impact of typical air leakage pathways on heat and moisture transport within wall assemblies for both Northern and Southern building applications. The experimental data from the laboratory tests were used to verify detailed heat and moisture (HAM) simulation models that could be used to evaluate a wider array of building applications and situations. Whole building testing at FSEC's Building Science Laboratory (BSL) systematically evaluated the energy and IAQ impacts of duct leakage with various attic and ceiling configurations. This systematic test carefully controlled all aspects of building performance to quantify the impact of duct leakage and unbalanced flow. The newest features of the EnergyPlus building simulation tool were used to model the combined impacts of duct leakage, ceiling leakage, unbalanced flows, and air conditioner performance. The experimental data provided the basis to validate the simulation model so it could be used to study the impact of duct leakage over a wide range of climates and applications. The overall objective of this project was to transfer work and knowledge that has been done on uncontrolled air flow in non-residential buildings in Florida to a national basis. This objective was implemented by means of four tasks: (1) Field testing and monitoring of uncontrolled air flow in a sample of New York buildings; (2) Detailed wall assembly laboratory measurements and modeling; (3) Whole building experiments and simulation of uncontrolled air flows; and (4) Develop and implement training on uncontrolled air flows for Practitioners in New York State.

    At the 5.5 MV Tandem VdG accelerator of the Institute of Nuclear Physics of N.C.S.R. 'Demokritos', Athens, Greece, an external ion-beam set-up has been recently developed and installed. The aim of this development was to integrate the analytical capabilities of the PIXE, RBS and PIGE ion beam techniques in one experimental set-up, so that to attain a complete elemental and near surface structural characterization of samples in an almost non-destructive way and without any limitation concerning their size or conductive state. A careful 3D mechanical drawing optimized the set-up experimental parameters achieving probe dimensions at the millimeter range (1 mm 2 ) and fulfilling the special requirements imposed for optimum performance of the aforementioned techniques, including the possibility to use heavier, than protons, ion beams. For the digital pulse processing of the X-ray, γ-ray and charged particle detector signals, novel hardware and software tools were developed based on a custom FPGA configuration. The first applications were focused in the quality control of materials that have been intentionally contaminated with a particular tracer-element ('tagged' materials). The tagged materials which were developed and tested are technologically authentic replicas of ancient attic ceramics with black glazed decoration. Analytical diagnostic studies were carried out for a few representative paintings of contemporary Greek painters in order to identify and document materials/pigments and techniques and eventually to prevent trade of fakes. Finally, ancient glass beads were also examined with respect to the sodium concentration and its in-depth homogeneity.

    2017-07-01

    In the Swedish Building Energy, Technical Status and Indoor environment study, a total of 1160 adults from 605 single-family houses answered a questionnaire on respiratory health. Building inspectors investigated the homes and measured temperature, air humidity, air exchange rate, and wood moisture content (in attic and crawl space). Moisture load was calculated as the difference between indoor and outdoor absolute humidity. Totally, 7.3% were smokers, 8.7% had doctor' diagnosed asthma, 11.2% current wheeze, and 9.5% current asthma symptoms. Totally, 50.3% had respiratory infections and 26.0% rhinitis. The mean air exchange rate was 0.36/h, and the mean moisture load 1.70 g/m 3 . Damp foundation (OR=1.79, 95% CI 1.16-2.78) was positively associated while floor constructions with crawl space (OR=0.49, 95% CI 0.29-0.84) was negatively associated with wheeze. Concrete slabs with overlying insulation (OR=2.21, 95% CI 1.24-3.92) and brick façade (OR=1.71, 95% CI 1.07-2.73) were associated with rhinitis. Moisture load was associated with respiratory infections (OR=1.21 per 1 g/m 3 , 95% CI 1.04-1.40) and rhinitis (OR=1.36 per 1 g/m 3 , 95% CI 1.02-1.83). Air exchange rate was associated with current asthma symptoms (OR=0.85 per 0.1/h, 95% CI 0.73-0.99). Living in homes with damp foundation, concrete slabs with overlying insulation, brick façade, low ventilation flow, and high moisture load are risk factors for asthma, rhinitis, and respiratory infections. © 2016 John Wiley & Sons A/S.

    We report the results of environmental sampling and modeling in a neighborhood adjacent to a wood processing plant. This plant used creosote and pentachlorophenol (PCP) to treat wood for over 70 years. Between 1999 and 2001, environmental samples were obtained to quantify the level of environmental contamination from the wood processing plant. Blood from 10 residents was measured for chlorinated dioxins and dibenzofurans. Soil sediment samples from drainage ditches and attic/dust samples from nearby residents' homes were tested for polychlorinated dioxins, furans, and polycyclic aromatic hydrocarbons (PAH). The dioxin congeners analysis of the 10 residents revealed elevated valued for octachlorodibenzo-p-dioxin and heptachlorodibenzo-p-dioxin compatible with PCP as the source. The levels of carcinogenic PAHs were higher than background levels and were similar to soil contamination on wood preserving sites. Wipe sampling in the kitchens of 11 homes revealed that 20 of the 33 samples were positive for octachlorinated dioxins with a mean value of 10.27 ng/m 2 . The soil, ditch samples, and positive wipe samples from the homes indicate a possible ongoing route of exposure to the contaminants in the homes of these residents. Modeled air exposure estimated for the wood processing waste chemicals indicate some air exposure to combustion products. The estimated air levels for benzo(a)pyrene and tetrachlorodibenzodiozin in this neighborhood exceeded the recommended levels for these compounds in some states. The quantitative data presented suggest a significant contamination of a neighborhood by wood processing waste chemicals. These findings suggest the need for more stringent regulations on waste discharges from wood treatment plants

    Insulating roofs with dense-pack cellulose (instead of spray foam) has moisture risks, but is a lower cost approach. If moisture risks could be addressed, buildings could benefit from retrofit options, and the ability to bring HVAC systems within the conditioned space. Test houses with unvented roof assemblies were built to measure long-term moisture performance, in the Chicago area (5A) and the Houston area (2A). The Chicago-area test bed had seven experimental rafter bays, including a control vented compact roof, and six unvented roof variants with cellulose or fiberglass insulation. The interior was run at 50% RH. All roofs except the vented cathedral assembly experienced wood moisture contents and RH levels high enough to constitute failure. Disassembly at the end of the experiment showed that the unvented fiberglass roofs had wet sheathing and mold growth. In contrast, the cellulose roofs only had slight issues, such as rusted fasteners and sheathing grain raise. The Houston-area roof was an unvented attic insulated with spray-applied fiberglass. Most ridges and hips were built with a diffusion vent detail, capped with vapor permeable roof membrane. Some ridge sections were built as a conventional unvented roof, as a control. In the control unvented roofs, roof peak RHs reached high levels in the first winter; as exterior conditions warmed, RHs quickly fell. In contrast, the diffusion vent roofs had drier conditions at the roof peak in wintertime, but during the summer, RHs and MCs were higher than the unvented roof (albeit in the safe range).

    The United States Coast Guard (USCG) constructs residential housing throughout the country using a basic template that must meet the minimum Leadership in Energy and Environmental Design (LEED) Silver criteria or better for the units. In Kodiak, Alaska, USCG is procuring between 24 and 100 residential multi-family housing units. Priorities for the Kodiak project were to reduce overall energyconsumption by at least 20% over existing units, improve envelope construction, and evaluate space heating options. USCG is challenged with maintaining similar existing units that have complicated residential diesel boilers. Additionally, fuel and material costs are high in Kodiak. While USCG has worked to optimize the performance of the housing units with principles of improved buildingenvelope, the engineers realize there are still opportunities for improvement, especially within the heating, ventilation, and air conditioning (HVAC) system and different envelope measures. USCG staff also desires to balance higher upfront project costs for significantly reduced life-cycle costs of the residential units that have an expected lifetime of 50 or more years. To answer thesequestions, this analysis used the residential modeling tool BEoptE+ to examine potential energy- saving opportunities for the climate. The results suggest criteria for achieving optimized housing performance at the lowest cost. USCG will integrate the criteria into their procurement process. To achieve greater than 50% energy savings, USCG will need to specify full 2x 6 wood stud R-21 insulationwith two 2 inches of exterior foam, R-38 ceiling insulation or even wall insulation in the crawl space, and R-49 fiberglass batts in a the vented attic. The air barrier should be improved to ensure a tight envelope with minimal infiltration to the goal of 2.0 ACH50. With the implementation of an air source heat pump for space heating requirements, the combination of HVAC and envelope savings inthe residential unit can save

    This report summarizes a multi-year research effort to develop a leak-free duct system that can be readily installed within the thermal envelope. There are numerous efforts underway to improve duct system efficiency. Most of these involve modifications to current technology such as air sealing techniques like mastic and aeroseal, snap together duct connections, and greater levels of insulation. This project sought to make a more significant stride forward by introducing a duct system of a material that can be more readily sealed and can exhibit lower friction losses. The research focused on the use of smooth internal surface, low friction plastic ducts that could be easily installed with very low air leakage. The initial system concept that was proposed and researched in Phase I focused on the use of thermoformed plastic ducts installed in a recessed roof truss underneath the attic insulation. A bench top thermoformed system was developed and tested during Phase I of the project. In Phase II, a first generation duct system utilizing a resin impregnated fiberglass duct product was designed and specified. The system was installed and tested in an Atlanta area home. Following this installation research and correspondence with code officials was undertaken to alleviate the continued concern over the code acceptance of plastic ducts in above ground applications. A Committee Interpretation response was received from the International Code Council (ICC) stating that plastic ducts were allowed, but must be manufactured from materials complying with Class 0 or Class 1 rating. With assurance of code acceptance, a plastic duct system using rotomolded high density polyethylene ducts that had passed the material test requirements by impregnating the material with a fire retardant during the molding process was installed in the basement of a new ranch-style home in Madison, WI.

    Highlights: • Improving DSM program impacts by targeting high energy users. • DSM energy savings potential hinges on pre-participation performance. • Targeting can benefit different utilities and energy efficiency programs. • Overall performance can be improved by up to 250% via targeting strategies. - Abstract: Electric utilities, government agencies, and private interests in the US have committed and continue to invest substantial resources – including billions of dollars of financial capital – in the pursuit of energy efficiency and conservation through demand-side management (DSM) programs. While most of these programs are deemed to be cost effective, and therefore in the public interest, opportunities exist to improve cost effectiveness by targeting programs to those customers with the greatest potential for energy savings. This article details an analysis of three DSM programs offered by three Florida municipal electric utilities to explore such opportunities. First, we estimate programs’ energy savings impacts; second, we measure and compare energy savings across subgroups of program participants as determined by their pre-intervention energy performance, and third, we explore potential changes in program impacts that might be realized by targeting specific customers for participation in the DSM programs. All three programs resulted in statistically significant average (per-participant) energy savings, yet average savings varied widely, with the customers who performed best (i.e., most efficient) before the intervention saving the least energy and those who performed worst (i.e., least efficient) before the intervention saving the most. Assessment of alternative program participation scenarios with varying levels of customer targeting suggests that program impacts could be increased by as much as 80% for a professional energy audit program, just over 100% for a high-efficiency heat pump upgrade program, and nearly 250% for an attic insulation

    A comprehensive radiological assessment of Kent Laboratory was conducted during September 1977, by the ANL Radiological Survey Group to determine if any radioactive contamination remained. The results of the assessment indicated the need for remedial action. Since 1977, the University has decontaminated this laboratory building, and in May 1983, the Department of Energy requested the ANL Radiological Survey Group to conduct a post-remedial-action survey. All the contaminated areas identified during the 1977 assessment were rechecked. Contamination remained in six of the rooms. Further decontamination of these areas was conducted by university personnel, and as a result, these areas are now free of contamination. However, a contaminated clay pipe in the attic remained. The clay pipe has since been removed and disposed of as solid radioactive waste. During the post-remedial-action survey, six soil samples were collected from excavation trenches dug in Rooms 1 and 2 as part of the University's remedial action efforts. Also, four sludge samples were taken from below the manhole covers in the basement of Kent Chemical Laboratory to assess the radiological condition of the sewer system. A radiological assessment of the sewer system had not been accomplished during the 1977 survey as per program direction. Radiochemical (fluorometric) and gamma-spectral analyses indicated that eight out of ten soil and sludge samples contained levels of radioactivity above expected background concentrations. The soil has since been further excavated. The building is now free of radioactive contamination in excess of background levels; however, the sewers do contain radioactive materials above background levels since contamination was found at appropriate access points. 6 references, 16 figures, 7 tables

    The objective of this study is to illustrate prevention strategies and management of vascular complications from the jugular bulb (JB) and internal carotid artery (ICA) during middle ear surgery or cochlear implantation. The study design is retrospective case series. The setting is tertiary referral university hospital. Patients were included if presented pre- or intraoperative evidence of high-risk anatomical anomalies of ICA or JB during middle ear or cochlear implant surgery, intraoperative vascular injury, or revision surgery after the previous iatrogenic vascular lesions. The main outcome measures are surgical outcomes and complications rate. Ten subjects were identified: three underwent cochlear implant surgery and seven underwent middle ear surgery. Among the cochlear implant patients, two presented with anomalies of the JB impeding access to the cochlear lumen and one underwent revision surgery for incorrect positioning of the array in the carotid canal. Subtotal petrosectomy was performed in all cases. Anomalies of the JB were preoperatively identified in two patients with attic and external auditory canal cholesteatoma, respectively. In a patient, a high and dehiscent JB was found during myringoplasty, while another underwent revision surgery after iatrogenic injury of the JB. A dehiscent ICA complicated middle ear effusion in one case, while in another case, a carotid aneurysm determined a cholesterol granuloma. Rupture of a pseudoaneurysm of the ICA occurred in a child during second-stage surgery and required permanent balloon occlusion without neurological complications. Knowledge of normal anatomy and its variants and preoperative imaging are the basis for prevention of vascular complications during middle ear or cochlear implant surgery.

    This research is a test implementation of an unvented tile roof assembly in a hot-humid climate (Orlando, FL; Zone 2A), insulated with air permeable insulation (netted and blown fiberglass). Given the localized moisture accumulation and failures seen in previous unvented roof field work, it was theorized that a 'diffusion vent' (water vapor open, but air barrier 'closed') at the highest points in the roof assembly might allow for the wintertime release of moisture, to safe levels. The 'diffusion vent' is an open slot at the ridge and hips, covered with a water-resistant but vapor open (500+ perm) air barrier membrane. As a control comparison, one portion of the roof was constructed as a typical unvented roof (self-adhered membrane at ridge). The data collected to date indicate that the diffusion vent roof shows greater moisture safety than the conventional, unvented roof design. The unvented roof had extended winter periods of 95-100% RH, and wafer (wood surrogate RH sensor) measurements indicating possible condensation; high moisture levels were concentrated at the roof ridge. In contrast, the diffusion vent roofs had drier conditions, with most peak MCs (sheathing) below 20%. In the spring, as outdoor temperatures warmed, all roofs dried well into the safe range (10% MC or less). Some roof-wall interfaces showed moderately high MCs; this might be due to moisture accumulation at the highest point in the lower attic, and/or shading of the roof by the adjacent second story. Monitoring will be continued at least through spring 2016 (another winter and spring).

    Achieving Building America energy savings goals (40% by 2030) will require many existing homes to install energy upgrades. Engaging large numbers of homeowners in building science-guided upgrades during a single remodeling event has been difficult for a number of reasons. Performance upgrades in existing homes tend to occur over multiple years and usually result from component failures (furnace failure) and weather damage (ice dams, roofing, siding). This research attempted to: A) understand the homeowner's motivations regarding investing in building science based performance upgrades; B) determining a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks; and C) access a business model that will manage all aspects of the contractor-homeowner-performance professional interface to ensure good upgrade decisions over time. The solution results from a synergistic approach utilizing networks of suppliers merging with networks of homeowner customers. Companies in the $400 to $800 billion home services industry have proven direct marketing and sales proficiencies that have led to the development of vast customer networks. Companies such as pest control, lawn care, and security have nurtured these networks by successfully addressing the ongoing needs of homes. This long-term access to customers and trust established with consistent delivery has also provided opportunities for home service providers to grow by successfully introducing new products and services like attic insulation and air sealing. The most important component for success is a business model that will facilitate and manage the process. The team analyzes a group that developed a working model.

    Full Text Available Aim: An age old and time tested technique of mosquito net requiring no energy, used by humans since prehistoric period was the inspiration behind this novel technique of fly proof net shed for livestock. With the aim to develop similar type of net shed for animals, which will protect them at night from biting of range of insects from Culicoides midges to mosquitoes, research was undertaken. Materials and Methods: Net shed with pitch roof (gable type was erected for use of livestock. The open inlet area was covered with 40 mesh size wire net. The roof at attic level was fitted with hurricane type of ventilator. Shed was used for animals at night hours only. vane anemometer was used for estimation of temperature and wind related parameters. Thermal humidity index (THI and air changes were calculated as per the standard formulas. Based on these parameters suitability of shed was judged. Results: It was observed that, due to netting of the shed population of Culicoides and other flies and incidences of their bites at night hours were considerably lowered. As a result, animals were found comfortable, and their body movements undertaken for wiping off these flies were significantly reduced from 196.50 to 22.16. All it accrued to increased milk yield to the tune of 18.97% in the net shed buffaloes as against control shed. Studies on suitability and comfort to animals were tested by estimating THI and air changes per hour in the net shed, which also revealed the estimates in comfortable regimen and ventilation, remained not much affected despite of netting. Other parameters studied for testing its more accuracy by taking other species of animals as kids, for them also, shed was found suitable through estimation of various physiological and behavioral parameters. Finally, the efficacy of shed was judged on the basis of cost effectiveness. Highly encouraging results on the above said parameters endorsed the effectiveness of the technique. Conclusion: A

    Different building constructions and craftsmanship give rise to different thermal performance and damage conditions. The building stock of most industrial countries consists of buildings of various age, and constructions, from old historic buildings with heavy stone or wooden construction, to new buildings with heavy or light concrete construction, or modern steel or wooden construction. In this paper the result from a detailed infrared survey of 50 buildings from six Swedish military camps is presented. The presentation is limited to a comparison of thermal performance and damage conditions of buildings of various ages, functions, and constructions, of a building period of more than 100 years. The result is expected to be relevant even to civilian buildings. Infrared surveys were performed during 1992-1993, with airborne, and mobile short- and longwave infrared systems, out- and indoor thermography. Interpretation and analysis of infrared data was performed with interactive image and analyzing systems. Field inspections were carried out with fiber optics system, and by ocular inspections. Air-exchange rate was measured in order to quantify air leakages through the building envelope, indicated in thermograms. The objects studied were single-family houses, barracks, office-, service-, school- and exercise buildings, military hotels and restaurants, aircraft hangars, and ship factory buildings. The main conclusions from this study are that most buildings from 1880 - 1940 have a solid construction with a high quality of craftsmanship, relatively good thermal performance, due to extremely thick walls, and adding insulation at the attic floor. From about 1940 - 1960 the quality of construction, thermal performance and craftsmanship seem to vary a lot. Buildings constructed during the period of 1960 - 1990 have in general the best thermal performance due to a better insulation capacity, however, also one finds here the greatest variety of problems.

    Full Text Available En se départissant de la dichotomie victorienne manichéenne de l’ange du foyer et de la femme déchue pour éclairer les personnages de Jane et Bertha dans leur ouvrage pionnier The Madwoman in the Attic, Sandra Gilbert et Susan Gubar étudièrent la première épouse de Rochester, folle, comme le double subversif de Jane, faisant ainsi de Jane et de Bertha les facettes d’un seul et même personnage. Malgré le rejet moderniste des excès supposés de l’ère victorienne, Rebecca de Daphne du Maurier exploite une intrigue triangulaire similaire qui réinterprète et recrée Rochester, Bertha et Jane à travers Maxime de Winter, Rebecca et Mrs de Winter. Les conceptions victoriennes des féminités doubles, des doublets féminins pour ainsi dire, sont perpétuées et réactualisées à travers les textualités néo-victoriennes. Néanmoins, peut-on vraiment voir dans Bertha un personnage que Rochester tente d’assagir par l’entremise de la figure de l’ange du foyer, plutôt qu’un archétype de la femme déchue ? Jane n’est-elle pas destinée à découvrir le secret de Rochester avant de l’épouser ? Mrs de Winter a-t-elle à ce point le sens du sacré qu’elle ne cherche pas à entrer en concurrence avec Rebecca ?

Their date in the Iberian Peninsula is some years later than that proposed for Athens. They did not appear till some years after the second half of the 5th c. B.C. Their production probably continued until the first quarter of the 4th century B.C. They are almost fixed in their form for about a century, but some differences in the outside decoration and the underside of the foot can be pointed out. Two main types are proposed for the second half of the 5th century and the first quarter of the 4th century B.C. The differences in date compared with those found at Athens can be explained as an adaptation of the workshops to the demands of Iberian customers. Athen's artisans continued making Castulo cups for export at a time when in Athens they did not use them any more, because the stemless cup had been replaced by the popular kantharoi and cup-kantharoi.

    2012-04-01

    The Aegean is a focus of important cultural achievements in Europe since the Neolithic period. The resulting abundance of archaeological remains, many of them below sea-level represent an advantageous area for the study of local relative sea-level change. We have carried out detailed mapping of Despotiko Island (SW of Antiparos) and its surrounding. Despotiko is situated almost exactly in the center of the Cyclades (as defined nowadays), more so than Delos, and therefore is very well suited for sea-level studies of the Cyclades. This beneficial location, combined with a spacious and protected bay, additionally may explain its former importance as stepping-stone in the Aegean Sea. The island is uninhabited at present, but Early Bronze Age settlement sites and graveyards as well as a large Archaic sanctuary proof its former importance. The sanctuary is situated on a gently northeast dipping slope in the northeast part of Despotiko, in range of sight of the Órmos Despotiko. Since 1997 large parts of this important sanctuary have been excavated during several excavation campaigns. Tectonically, Despotiko, Antiparos and Paros, belong to the Attic-Cycladic Crystalline of the Central Hellenides, a stack of metamorphic tectonic nappes, mainly comprising variable types of gneiss, schist, marble and amphibolite, and tectonic slices of unmetamorphosed sediments on top, separated by low-angle normal faults from the metamorphic units below. Submerged archaeological structures at the sea bottom of the Órmos Despotiko, a Classical marble inscription from the sanctuary and partly submerged agriculture trenches at the east coast Despotiko, indicate that the relative sea-level in this area was some 3 m lower during the Early Bronze Age and still more than 1 m lower during Classical time. These values of relative sea-level rise indicate a subsidence component additional to the global sea-level rise in the investigated time period. Neglecting possible vertical tectonic movements and

    The Rhodope Domain in NE Greece consists of different tectonometamorphic complexes involved in the Alpine collisional history between the Eurasian and African plates. In the Kechros Complex, which is the lowermost tectonic unit in the East Rhodope, a lense of kyanite eclogite occurs within orthogneiss and common eclogites are found between serpentinized peridotite and underlying pelitic gneisses. In kyanite eclogite, the high-pressure (HP) mineral assemblage is Grt + Omp (Jd35-55) + Ky + Ph + Qz + Rt + (indirectly inferred Tlc + Law); a Na-rich tremolite and zoisite formed at or near peak metamorphic conditions. In common eclogites, the HP mineral assemblage is Grt + Omp (Jd29-41) + Rt and, with less certainty, Amp (Gln-rich + Brs + Wnc + Hbl) ± Czo. The inclusions in garnet are glaucophane, actinolite, barroisite, hornblende, omphacite, clinozoisite, titanite, rutile and rarely paragonite and albite. In kyanite eclogite, peak P- T conditions are constrained at 2.2 GPa and 615°C using garnet-omphacite-phengite geothermobarometry and very similar values of 585 ± 32°C and 2.17 ± 0.11 GPa with the average P- T method, by which conditions of formation could also be narrowed down for the common eclogite (619 ± 53°C and 1.69 ± 0.17 GPa) and for a retrogressed eclogite (534 ± 36°C and 0.77 ± 0.11 GPa). Ages for the HP metamorphism in the Kechros Complex are not yet available. A Rb-Sr white mica age of 37 Ma from orthogneiss records a stage of the exhumation. The HP event may be coeval with the Eocene HP metamorphism (49-55 Ma) recorded in the Nestos Shear Zone in Central Rhodope and in the Attic-Cycladic crystalline belt, where it is interpreted as the result of subduction and final closure of the Axios/Vardar ocean and subsequent subduction of the Apulian continental crust (a promontory of the Africa continent) under the southern margin of the European continent in the late Cretaceous and early Tertiary.

    Homosexuality and pedophilia in ancient Greece greatly concerned many researchers who were mainly interested in highlighting the social aspect of this phenomenon in ancient Greek society. An important source on the subject was the paintings of a man and his lover in attic black and red figured pottery, up to the end of the 5th century BC. Another main source was the information that derived from the texts of ancient Greek literature, especially poetry. Homosexuality was not only referring to relationships between males, but it was also manifested in lesbian love. It is believed that in the Homeric world homosexuality was not favored. In Greek society of the archaic period, the restriction of women at home, the satisfaction of sexual needs with courtesans, the marriage for the purpose of maintaining and managing the property, put women aside, marginalizing them in terms of social life, impeding the cultivation of emotional relationships between sexes. At the same time, in the society of those times, the aristocratic ideal, the constant communication of men during military training and the war, the male nudity in sports and the promotion of beauty and bravery in athletic contests, as well as the gatherings and the entertainment of men at the symposia, created a suitable substrate in which male homosexuality could develop. In this context, pedophile relationships were developed mainly during the archaic period, as recorded on vase paintings, where a mature man developed a special relationship with a teenager of the same social class. The mature man had the role of mentor for the juvenile, he would look after him and cover his living expenses and education cost. In this relationship, exhibiting predominantly the social dimension of an initiation process and introduction to adult life, the erotic homosexual intercourse could find a place to flourish. The above-mentioned relationship could not last forever, given that this would later transform into an emotional

    Full Text Available The aim of this article is to assess the traditional iconographic identification of the obverse of a 4th century Greek bell crater from the Iberian site of La Loma del Escorial de Los Nietos (Cartagena, Murcia. The scene has been identified as an apotheosis of Heracles. Nevertheless, a detailed analysis of its iconography and of a feature neglected in the previous study of the vase by its excavators —the remains of a shield— make it possible to argue in favor of an apobates race instead —the only scene of this type attested in the Iberian Peninsula. I present here an analysis of both iconographic motifs —the apotheosis of Heracles and the apobates race— that will reveal interesting findings on the ways in which images and iconographic types acquire meaning. It also sheds light on the kind of images favored by the receptors of these vases in the Peninsula — the Iberians. An up-to-date catalogue of Attic vases depicting each theme is included.En el presente artículo se revisa la identificación iconográ- fica de la cara A de una cratera griega fragmentaria del siglo IV a.C. procedente del yacimiento ibérico de La Loma del Escorial de Los Nietos (Cartagena, Murcia. La escena se ha identificado tradicionalmente como la apoteosis de Heracles, no obstante, tras un análisis detallado de la misma, en particular del resto de un escudo previamente inadvertido que porta el personaje principal, creemos que la iconografía se corresponde con la del apobates victorioso, un unicum en la Península Ibérica. Presentamos un análisis de ambos motivos iconográficos que revelará interesantes conclusiones sobre el funcionamiento de los tipos iconográficos y mecanismos de creación de significado en la pintura de vasos de la época, así como sobre el tipo de imágenes estimadas por los receptores de esas piezas en la Península Ibérica, los íberos. Se incluye también un catálogo actualizado de los vasos áticos que portan ambos temas.

    Carbon monoxide (CO) and particulate matter (PM 2.5) were measured in two reconstructed Danish farmhouses (17-19th century) during two weeks of summer. During the first week intensive measurements were performed while test cooking fires were burned, during the second week the houses were monitored while occupied by guest families. A masonry hearth was located in the middle of each house for open cooking fires and with heating stoves. One house had a chimney leading to the outside over the hearth; in the other, a brickwork hood led the smoke into an attic and through holes in the roof. During the first week the concentration of PM 2.5 averaged daily between 138 and 1650 μg m -3 inside the hearths and 21-160 μg m -3 in adjacent living rooms. CO averaged daily between 0.21 and 1.9 ppm in living areas, and up to 12 ppm in the hearths. Highest concentrations were measured when two fires were lit at the same time, which would cause high personal exposure for someone working in the kitchens. 15 min averages of up to 25 400 μg m -3 (PM 2.5) and 260 ppm CO were recorded. WHO air quality guidelines were occasionally exceeded for CO and constantly for PM 2.5. However, air exchange and air distribution measurements revealed a large draw in the chimney, which ensured a fast removal of wood smoke from the hearth area. The guest families were in average exposed to no more than 0.21 ppm CO during 48 h. Based on a hypothetical time-activity pattern, however, a woman living in this type of house during the 17-19th century would be exposed to daily averages of 1.1 ppm CO and 196 μg m -3 PM 2.5, which exceeds WHO guideline for PM 2.5, and is comparable to what is today observed for women in rural areas of developing countries.

According to Burkhardt Wesenberg, all four schemes stem from a common prototype – the painting Io by a late Attic painter, Nicias of Athens (Pliny, Natural History 35.132. What seems likely, however, is that Ovid’s new version with Syrinx influenced a rearrangement of the figures in the original composition, which led to the formation of new schemes.

    Carefully controlled and well documented experiments have been done for two candidate configurations to control the heat load on a conditioned space. The 2:1 PCM/perlite mixture and the 6:1 PCM/perlite mixture, both on a weight basis, accomplished thermal control. The 2:1 system seemed to have enough PCM to be effective and involve a much larger fraction of its PCM in diurnal freezing and melting than the 6:1 system. It is a good starting point for engineering design of an optimum thermal control system. The results from the 2:1 system were reproduced with the computer program HEATING to prove that we know the relevant mechanisms and thermophysical properties of the PCM used in the system. Even without a model for the supersaturation and hysteresis that this material exhibited, HEATING reproduced the heat fluxes to the conditioned space in the experiments accurately enough to mirror the good thermal control performance of the system. The modified sensible heat capacity that was used in HEATING is a handy way to account for phase change effects and could be used in a subroutine to compute hourly phase change effects for whole building models like DOE-2. The experiments were done with PCM/perlite mixtures sealed in small methylmethacrylate boxes and covered top and bottom by XPS. The boxes allowed precise placement of the instrumentation used to follow the phase change effects. The XPS gave high R-value per unit thickness. A more practical prototype configuration such as PCM/perlite hermetically sealed in plastic pouches between layers of batts or blown-in insulation should be tested over a larger cross section. A good candidate is the whole attic cavity of the manufactured home test section used in the present work. Use of a PCM that does not exhibit supersaturation and hysteresis would make interpretation of the results easier. If the results of the larger scale test areas are as encouraging as the test cell results, a whole house model with a phase change

    During the last three decades of energy-efficiency research, there has been limited study of heat transfer to slab-on-grade foundations in cooling-dominated climates. Most experimental research has focused on the impact of slab-on-grade foundations and insulation schemes on heat losses in heating-dominated climates. This is surprising because the floor area in single-family homes is generally equal to wall area, window area, or attic area, all of which have been extensively evaluated for heat-transfer properties. Moreover, slab foundations are the most common foundation type in cooling-dominated climates. Slab-on-grade construction is very popular in southern states, accounting for 77% of new home floors according to 2014 U.S. Census data. There is a widespread perception that tile flooring, as opposed to carpet, provides a cooler home interior in warm climates. Empirical research is needed because building energy simulation software programs running DOE-2 and EnergyPlus engines often rely on simplified models to evaluate the influence of flooring on interior temperature, even though in some cases more detailed models exist. The U.S. Department of Energy Building America Partnership for Improved Residential Construction (BA-PIRC) performed experiments in the Florida Solar Energy Center’s Flexible Residential Test Facility intended to assess for the first time (1) how slab-on-grade construction influences interior cooling in a cooling-dominated climate and (2) how the difference in a carpeted versus uncarpeted building might influence heating and cooling energy use. Two nominally identical side-by-side residential buildings were evaluated during the course of 1 year, from 2014 to 2015: the east building with a pad and carpet floor and the west building with a bare slab floor. A detailed grid shows temperature measurements taken on the slab surface at various locations as well as at depths of 1.0 ft, 2 ft, 5.0 ft, 10.0 ft, and 20.0 ft below the surface. Temperature

    counter battens, providing a nailing surface for the concrete tile. This double batten construction forms an inclined air channel running from the soffit to the ridge. The bottom surface of the channel is formed by the roof decking and is relatively flat and smooth. The top surface is created by the underside of the roofing tiles, and is designed to be an air permeable covering to alleviate the underside air pressure and minimize wind uplift on the tiles. The resulting air flows also have a cooling influence which further complicates prediction of the heat penetrating through the deck because an accurate measure of the airflow is required to predict the heat transfer. Measured temperatures and heat flows at the roof surface, within the attic and at the ceiling of the houses are discussed as well as the power usage to help gauge the benefit of cool-pigmented reflective roof products fitted with and without ventilation above the roof deck. Ventilation occurring above the deck is an inherent feature for tile roof assemblies, and is formed by an air space between the exterior face of the roof sheathing and the underside of the tile. The greater the tile s profile the greater is the effect of the ventilation which herein is termed above-sheathing ventilation (ASV). However, because of the complexity of the thermally induced flow, little credit is allowed by state and federal building codes. ASHRAE (2005) provides empirical data for the effective thermal resistance of plane air spaces. A -in. (0.0191-m) plane air space inclined at 45 with the horizontal has an RUS-0.85 (RSI-0.15) . Our intent is to help further deploy cool color pigments in roofs by conducting field experiments to evaluate the new cool-colored roofing materials in the hot climate of Southern California. The collected data will be used to showcase and market the performance of new cool-roof products and also to help formulate and validate computer codes capable of calculating the heat transfer occurring within

    installation labor and materials, and $627 for overhead and management), and the benefit-to-cost ratio was 1.48. A general trend toward higher-than-average fuel-oil savings was observed in houses with high pre-weatherization fuel-oil consumption. Program savings could likely be increased by targeting higher energy consumers for weatherization, although equity issues would have to be considered. Weatherization measures associated with higher-than-average savings were use of a blower door for air-sealing, attic and wall insulation, and replacement space-heating systems. Space-heating system tune-ups were not particularly effective at improving the steady-state efficiency of systems, although other benefits such as improved seasonal efficiency, and system safety and reliability may have resulted. The Program should investigate methods of improving the selection and/or application of space-heating system tune-ups and actively promote improved tune-up procedures that have been developed as a primary technology transfer activity. Houses were more air-tight following weatherization, but still leakier than what is achievable. Additional technology transfer effort is recommended to increase the use of blower doors considering that only half the weatherized houses used a blower door during air sealing. A guidebook developed by a committee of experts and covering a full range of blower-door topics might be a useful technology transfer and training document. Weatherization appeared to make occupants feel better about their house and house environment.

In some homes, heat flux transducers are installed on the basement walls to help determine the insulating qualities of the technologies and practices. EnergyGauge is used to estimate the pre-retrofit and post-retrofit home energy rating system (HERS) index and reduction in energy consumption and energy bill. In a follow-up report, data from the installed sensors will be presented and analyzed as well as a comparison of the post-retrofit energy consumption of the home to the EnergyGauge model of the post-retrofit home. Table ES1 shows the retrofits that were completed at the eight households where some or all of the recommended retrofits were completed. Home aliases are used to keep the homeowners anonymous. Some key findings of this study thus far are listed as follows. Some homeowners (50%) are not willing to spend the money to reach 30 50% energy savings. Quality of retrofit work is significantly variable among contractors which impact the potential energy savings of the retrofit. Challenges exist in defining house volume and floor area. Of the five homes that completed all the recommended retrofits, energy bill savings was not the main driver for energy retrofits. In no case were the retrofits cost neutral given a 15 year loan at 7% interest for the retrofit costs.

    Sector field inductively coupled plasma mass spectrometry (SF-ICPMS) has been used with analysis of solution samples and laser ablation (LA) of electrodeposited alpha sources to characterize plutonium activities and atom ratios prevalent in the western USA. A large set of surface soils and attic dusts were previously collected from many locations in the states of Nevada, Utah, Arizona, and Colorado; specific samples were analyzed herein to characterize the relative contributions of stratospheric fallout vs. Nevada Test Site (NTS) plutonium. This study illustrates two different ICPMS-based analytical strategies that are successful in fingerprinting Pu in environmental soils and dusts. Two specific datasets have been generated: (1) soils are leached with HNO 3 -HCl, converted into electrodeposited alpha sources, counted by alpha spectrometry, then re-analyzed using laser ablation SF-ICPMS; (2) samples are completely dissolved by treatment with HNO 3 -HF-H 3 BO 3 , Pu fractions are prepared by extraction chromatography, and analyzed by SF-ICPMS. Optimal laser ablation and ICPMS conditions were determined for the re-analysis of archived alpha spectrometry ''planchette'' sources. The best ablation results were obtained using a large spot size (200 μm), a defocused beam, full repetition rate (20 Hz) and scan rate (200 μm s -1 ); LA-ICPMS data were collected with a rapid electrostatic sector scanning experiment. Less than 10% of the electroplated surface area is consumed in the LA-ICPMS analysis, which would allow for multiple re-analyses. Excellent agreement was found between 239+240 Pu activities determined by LA-ICPMS vs. activity results obtained by alpha spectrometry for the same samples ten years earlier. LA-ICPMS atom ratios for 240 Pu/ 239 Pu and 241 Pu/ 239 Pu range from 0.038-0.132 and 0.00034-0.00168, respectively, and plot along a two-component mixing line ( 241 Pu/ 239 Pu = 0.013 [ 240 Pu/ 239 Pu] - 0.0001; r 2 = 0.971) with NTS and global fallout end

Another work attributed to Bonazza is a large wooden gloriole with clouds, cherubs and a putto, above the altar in the Giustachini chapel in the church of Santa Maria del Carmine at Padua. The article attributes two stone angels and a putto on the attic storey of the high altar in the church of Santa Caterina on the island of Mazzorbo in the Venetian lagoon to Giovanni’s son Francesco Bonazza (Venice, c.1695 – 1770. Finally, Antonio Bonazza (Padua, 1698 – 1763, the most talented and well-known of Giovanni Bonazza’s sons, is identified as the sculptor of the exceptionally beautiful marble tabernacle on the high altar of the parish church at Kali on the island of Ugljan. The sculptures which the author of the article attributes to the Bonazza family and to Giovanni Bonazza’s teacher, l’Ongaro, demonstrate that the oeuvres of seventeenth- and eighteenth-century Venetian masters are far from being closed and that we are far from knowing the final the number of their works. Moreover, it has to be said that not much is known about Giovanni’s works in wood which is why every new addition to his oeuvre with regard to this medium is important since it fills the gaps in a complex and stylistically varied production of this great Venetian sculptor

    (Germania Superior, where the Parca is replaced with Daedalus, and on a sarcophagus from Asia Minor depicting Icarus’ life. Based on the narrative cycle of Icarus’ life on that sarcophagus, Salvatore Calderone has pointed out a Neoplatonic explanation of the myth: that the fight and fall could symbolise the soul which goes into the sky, from where it falls to Earth again. As Icarus in the Danubian provinces is never shown falling but rather flying or about to take wing (the only exception being the relief from Carnuntum, the image may express a Neoplatonic thesis and the apotheosis of the deceased. The provinces display at least three elementary types: Icarus standing alone with outstretched winged arms – this type probably derives from Aquileia; Icarus in relief, together with the Parca or Daedalus; and the bust of Icarus in the tympanum of the stele or acroterium. The fragment in Joanneum has most probably arrived from one of the Attic sarcophagi, where the Parca often appears by the side of the protagonists who die prematurely.

This clinic is an extension of that run by the Sisters of Saint Benedict in Lechnerstrasse, Munich. It consists of two blocks, of 4 and 5 floor levels. It has a semibasement, housing the services, and some spare rooms and other facilities, described in the enclosed plans. The ground floor provides room for 25 beds, for the older boys. On the second floor there are 30 beds for those recently born, whilst the third floor has space for 30 beds for prematurely born babies. The nurses live in the attic, where there are 15 bedrooms, each with two beds, a kitchen and suitable auxiliary facilities. Much thought has been given to the design of details, the general distribution and circulation system has been planned with much care, and the overall functional efficiency of the building as a children's clinic has been kept a paramount factor. All this makes this building an outstanding one among those of this type.Los objetivos principales perseguidos aquí son: conseguir una eficaz vigilancia y protección de los niños; organizar los puestos de trabajo de las enfermeras para que resulten prácticos y agradables, y crear un ambiente familiar La clínica construida —como ampliación de las instalaciones que las Hermanas de San Benito poseen en la calle Lachner, en Munich— comprende dos cuerpos de edificio unidos, de 4 y 5 plantas de altura, respectivamente, y está distribuida del siguiente modo: el semisótano aloja, además de la zona de servicios, una serie de dependencias, que vienen descritas en la respectiva documentación gráfica. La planta baja alberga 25 camas; está destinada a los niños mayores y colegiales; la planta primera, con 30 camas, a los recién nacidos, y la planta segunda, con 30 camas, a la sección de prematuros

    In the south-eastern East European platform and Urals, as well as the young Scythyan platform, the Late Alpine collision deformations are widely spread. First of all, these are crumbled aulacogen covers (the Azov Sea, Dnieper-Donets, and Pachelma aulacogens). In some places the covers were dislocated conformably with platform basements but commonly they were partly detached from it with formation of inversion foldbelts (such as the Donets coal basin in the Alpine stage, Saratov and Kerensk-Chembar dislocations). Basements of some anteclises (the Voronezh, Tokmovo, and Volga-Urals ones) dividing the aulacogens were also involved into deformations. There the greatest upthrusting of basement onto cover can be observed (e.g., the Zhigouli upthrust). In general the thrusting and folding occurred during the Early Miocene-Quaternary, with its periodicity strictly corresponding to that of the Late Alpine tectonic phases in the Greater Caucasus: Early Miocene (the H. Stille,s Styrian phase), terminal Miocene-initial Pliocene (the Attic and Rhodanian phases), Eo-Pleistocene (the Valachian phase). Beside the synchronous occurrences, there are some other evidences of relation of intraplate deformations to the Arabia-Eurasa collision in its Caucasian region: (i) sublatitudinal (up to WNW-ESE strike) orientation of the intraplate upthrusts and folds, (ii) wide distribution of structurally manifested strike-slip zones as well as similarity in orientation and location between the right and left strike-slips considered with those of the Greater Caucasus: domains of the formers are built up to the north the domains of the latters, (iii) directed southward increasing basement involvement into the neotectonic deformations. For example, in the Donets-Azov region a basement neotectonic megafold was imposed not only onto Donets Herzinian foldbelt but also on the Precambrian basement of the Rostov high of the Ukrainian shield. To some extent, this megafold resembles a northern wing of the

    Full Text Available It is appropriate and in some cases necessary, to arrange a special fire fighting reservoir, the size of which would vary depending on the number of buildings in a townhouse village. In case of fire, water can be taken out of it with the help of a fire pump, which is sometimes the only possible solution due to the pressure reduction in the networks of domestic water supply of villages.A water tank may also be useful for a household, as it offers a water reserve for a water supply network to assure continuous water supply to consumers in case of an accident (pump malfunction, power outage, or in case of discrepancy between regimes of water supply outside the network and water consumption inside a building. The tank is to be placed in a heated room, located as high as possible inside a building, for example, in the attic, in order to prevent water freezing. The tank volume may be about 200 300 liters; the tank is often made of steel. For the purpose of fire safety, there should always be an emergency ten-minute water supply in the tank for fire extinguishing purposes. It is worth mentioning that a free-flow water tank is preferable to a power-driven hydropneumatic one to assure an emergency supply of water for a particular period of time even in case of power failure.An electronic no-touch faucet can be even more efficient; it is activated by placing hands under a special sensor. It also has a function of maintaining a pre-set temperature, thus preventing hot water burns. It is desirable to install this a faucet in the bathroom close to the bath tub.Проблемы водосбережения выходят на первый план как в больших городах, так и в поселках малоэтажной застройки. Рассмотрены технические решения, позволяющие снизить потребление воды в несколько раз для сокращения

  1. Evaluating Cool Impervious Surfaces: Application to an Energy-Efficient Residential Roof and to City Pavements

    heating savings of 4% and electric heating savings of 3%. The slightly positive fractional annual heating energy savings likely resulted from the tile roof's high thermal capacitance, which increased the overnight temperature of the attic air. Thus cool tile roofs should be perceived as a technology that provides energy and environmental benefits during the cooling season as well as the heating season. The second topic investigates the direct and indirect effects of cool pavements on the energy use of California's building stock. First, a simple urban canyon model was developed to calculate the canyon albedo after the user provides the solar position, canyon orientation, and dimensions of the canyon walls, road, and setbacks. Next, a method is presented to correct the values of temperature changes obtained from previous urban climate models to values that would be obtained from canyon geometries that distinguish between road and setbacks (e.g. sidewalk, front yard). The new canyon model is used to scale the temperature changes obtained from a recent urban climate model that simulated the climatological impact of cool pavements on various California cities. The adjusted temperature changes are then combined with building energy simulations to investigate the effect of cool pavements on the cooling, heating, and lighting energy uses of buildings as well as the environmental impact related to these energy uses. Net (direct + indirect) conditioning (cooling + heating) energy savings and environmental savings from cool pavements were smaller in residential buildings than in commercial buildings. Additionally, residential buildings strongly dominate the building stock in all of the evaluated cities. Therefore, even though most cities yielded conditioning energy and environmental savings, they were small due to the minuscule savings from the residential buildings. When increasing the albedo by 0.20 of all public pavements in different California cities, Los Angeles was the city

  2. The Mystery of the Past Haunts Again: Jane Eyre and Eugenie Marlitt’s Die zweite Frau Le mystère du passé hante encore: l’influence de Jane Eyre sur Die zweite Frau d’Eugenie Marlitt

    Full Text Available Charlotte Brontë’s Jane Eyre is a classic in women’s fiction. When it was published in 1847, it made an immediate impact in mid-Victorian England, partly because it drew on the paradigmatic story of a romance heroine, partly because it interpreted the needs of the women of the time. Since then, the Thornfield Hall attic where Bertha Mason is kept hidden by the master of the house, Mr. Rochester, has become the metaphor of a feminine place of imprisonment and,at the same time, of rebellion against patriarchal rules.About thirty years after Jane Eyre, another woman writer published a book which evokes the haunting atmosphere of the Thornfield Hall theme, i.e., the German writer Eugenie Marlitt, the author of Die zweite Frau ( The second wife, 1874.Interestingly, Marlitt seems to recapture, while rewriting it, the character of Bertha within the context of German domestic fiction. Bothnovels explore indeed the issue of the imprisoned and socially marginalised woman in terms of ethnicity to show how gender roles are inevitably complicit with power relations. In Jane Eyre and Die zweite Frau the house motif is a pivotal element that leads to our understanding of the female characters, but it is above all the mystery that reverberates through the houses of the two novels, represented by two women, the Creole Bertha  and the Indian Lotusblume, which, being crucial to the articulation of the discursive thrust underlying the two narratives, discloses the multi-layered construction of femininity.Jane Eyre de Charlotte Brontë est un classique de la littérature féminine. Lors de sa publication en 1847, le roman eut un impact immédiat sur l’Angleterre victorienne, d’une part parce qu’il racontait l’histoire paradigmatique d’une héroïne de romance et d’autre part parce qu’il se faisait l’interprète des désirs des femmes de l’époque. Depuis, le grenier de Thornfield Hall où le maître de maison cache Bertha Mason, est devenu la

    .These new forms and present-day materials, which allow for both the spoken word and silence, isolation and continuity, contemplation and activity, are acceptable in the Atarazanas and were proposed with the intention of unveiling the lesson the building itself has transmitted day by day since its origin. Our fourth step was to repair the Attic in the Head Section of the building.Solving essential problems, understanding the significance of the Atarazanas, amid building and architecture, and affording the use of the rooms, has been the constant guiding force of our work, and by opening the building to the public contribution is made towards the total restoration, which is perhaps the principal reason behind our project.Con frecuencia el arquitecto L. Kahn refería que la sala, entendida como forma habitable, era el elemento esencial de la arquitectura y que ésta consistía en “una asociación de salas”. Se podría afirmar que en las Atarazanas la sala toma forma de nave y que su arquitectura es básicamente el resultado de la yuxtaposición de diecisiete grandes naves de 100 m de longitud, 10 m de latitud y 10 m de altura, cuyas cubiertas fueron presumiblemente estructuras de madera análoga a las de las mezquitas.Nuestra intervención se ha ceñido al conjunto formado por las siete primeras naves.La primera se encaminó al descubrimiento integral del espacio, suprimiendo las diversas capas y texturas que lo fueron ocultando hasta conseguir la manifestación del espacio estructural.La obra supuso un decidido primer paso para devolver la insólita espacialidad a esta construcción arquitectónica, de carácter escultórico, proponiendo que en una intervención futura se recupera una de las naves en toda su verdadera magnitud, retirando todo el relleno de la misma.Una segunda intervención se orientó para su apertura a la visita pública. Esta obra nos permitió ensayar intervenciones y materiales que deben dotar al espacio estructural de los necesarios soportes
