Modern materials and construction solutions draw more and more attention to ecology and building certification. Among the criteria appearing in revitalization, an important element is bringing plants back into heavily urbanized areas. In its natural form, this is not possible to carry out everywhere, often requiring large amounts of space. Nowadays, however, there are a number of green roofs and green wall systems, allowing "greener" construction without making significant changes in the urban environment. The article includes a presentation and analysis of selected solutions of biological surfaces known as green roofs and green walls, specifying various solutions and their most important features. The case study focuses primarily on material and design solutions, as well as the potential benefits, risks and limitations in their use. Plants structures on the surfaces of vertical and horizontal partitions continue to be a very interesting alternative to take into account when applying for grants, such as LEED or BREEAM certificates.

Green certificates and carbon trading in the Netherlands

International Nuclear Information System (INIS)

Boots, M.

2003-01-01

The combination of trading schemes for green certificates and for carbon, as they are implemented and planned in the Netherlands, imply a complete separation of green certificates and CO 2 markets. This means that the costs of CO 2 reduction will be reflected in the spot price of electricity and that the price of green certificates only reflects the additional cost of RE development. However, since the green certificate scheme is already implemented, while the carbon trading scheme is not, it is unclear if currently the green certificate value includes the CO 2 reduction value of RE production. It is important that buyers and sellers in the market for green certificates agree on what they are trading, therefore this issue should be clarified

Tradable green certificates in Flanders (Belgium)

International Nuclear Information System (INIS)

Verbruggen, Aviel

2004-01-01

The paper provides details on green certificate systems in Belgium. The Flemish region has established a system and the Walloon region is preparing a slightly different one. The lack of uniformity and consequently of transparency in one country emphasises the need for more EU leadership in the field. The main part of the article analyses the established Flemish system. Green certificates are complementary to other instruments that promote renewable electricity, e.g. direct subventions on the feed-in price of green electricity or direct subventions on capital investments. Certificates execute a forcing effect on the actual development of green power if the imposed shares of green power in total sales are significant and if the fine level is at the height to enforce the quota. If the fine is too low the incentive effect turns into a financing tax effect. When the green certificate system does the job it is designed for, i.e. operating at the edge of the RES-E development and organise the transition from a non-sustainable to a sustainable power system, certificate prices will be high and reduce end-use consumption of electricity. A segmentation of the RES-E sector along the various RES-E technologies is a necessity to keep any certificate system affordable, effective and efficient. One can segment the tradable certificate market or one can assign a different number of certificates to a different RES-E technology project. Both solutions require an intensive follow-up of cost structures and of other policy measures (subventions), but given the infant state of understanding and experience segmenting markets may be best in the nearby years.

Modeling of a green certificate market

International Nuclear Information System (INIS)

Marchenko, O.V.

2008-01-01

The paper considers one of the economic mechanisms, stimulating the introduction of renewable energy sources (RES) - a green certificate market. A mathematical model was developed to describe a supply and demand balance in the electricity and green certificate markets simultaneously. The sellers of certificates are RES owners, who obtain certificates for each unit of electricity produced, and the buyers are consumers, who are obliged by law to buy a certain share of this electricity. Equilibrium structures of the power system including RES with stochastic operation conditions are calculated. The prices of electricity and certificates, as well as the total economic effect of the system are determined taking into account external costs (environmental damages). The paper shows that a mechanism of green certificates is not an ideal means for minimizing the impact of energy on the environment: the economic effect turns out to be smaller than the maximum possible one. However, this deviation is relatively small, therefore the green certificate market allows the external effects to be partially taken into account. Such a market creates incentives for investors, electricity producers and consumers to make power sources mix, modes of electricity production and consumption closer to the optimum ones in terms of the economy as a whole.

Green certificate in an international market

International Nuclear Information System (INIS)

Nese, Gjermund

2002-01-01

An analytical equilibrium model for a simultaneously functioning electricity market and a market for Green Certificates is formulated. The main focus is on the effects of changing the percentage requirement which is in end use consumption. We start by looking briefly at an autarky market before opening the trade of electricity and certificates. The results show that the percentage requirement is a very imprecise instrument as to increase the provision of green electricity. In none of the cases considered will an increase of the percentage requirement in a country necessarily result in an increase in the generation of green electricity in the country itself. When opening for trade, the results show that the increase of the percentage requirement in one country can have a negative effect on green electricity generation in this country, but a positive effect in the other country. Further it is shown that in the case of an open certificate market where the certificates can be traded at a given international price, a country will maximise it's generation of green electricity by setting the percentage requirement equal to zero.

A market for green certificates may cause less green electricity to be produced

International Nuclear Information System (INIS)

Haugneland, Petter

2004-01-01

The Norwegian government wants to establish in 2006 a market for trading with green certificates which will be issued to producers of new renewable electricity. These certificates will be sold to the consumers, which will be instructed to by a certain amount of green electricity. In 2005 a market will be established for trading with emission quotas of greenhouse gases; in this market, power producers and other industry that emits greenhouse gases must buy emission permits. Some experts, however, say that a market for trading with green certificates may at worst give less production of green electricity, counter to the intention. But a quota system may indirectly increase the production of green electricity, and at the same time one avoids many of the inconveniences involved in a green certificate market

This article gives details of the Green-e environmental certification programme which certifies electricity generated from renewable energy sources in the US. This first non-profit certification programme originally was set up for California, and has now spread to other regions. The objectives of the Green-e programme, the need for the electricity product to meet minimum criteria to qualify, marketer requirements, verification of product claims, administration of the programme, and the second year programme results are discussed. The way in which the Green-e programme fits in with other programmes such as those set up by the state and federal customer protection agencies to help consumers select environmentally superior power is described.

Build green and conventional materials off-gassing tests: A final report

Build Green is a certification program that will identify and label building products with a known recycled content. The introduction of these recycled materials has raised the concern that they may emit more indoor pollutants than conventional materials. This study addresses that concern by analyzing Build Green and conventional materials to assess their potential for off-gassing. The study involved emission tests of 37 materials including carpets, carpet undercushions, structural lumber, foundation material, insulation, drywall, fiberboard, counter tops, and cabinetry. The results presented in this report include comparisons of Build Green and conventional materials in terms of emissions of volatile organic compounds and formaldehyde, the material loading ratio, and discussion of the specific sources of the emissions.

Along with the growing interest in greenhouse gas reduction, the effect of greenhouse gas energy reduction from implementing green buildings is gaining attention. The government of the Republic of Korea has set green growth as its paradigm for national development, and there is a growing interest in energy saving for green buildings. However, green buildings may have financial barriers that have high initial construction costs and uncertainties about future project value. Under the circumstances, governmental support to attract private funding is necessary to implement green building projects. The objective of this study is to suggest a financing model for facilitating green building projects with a governmental guarantee based on Certified Emission Reduction (CER). In this model, the government provides a guarantee for the increased costs of a green building project in return for CER. And this study presents the validation of the model as well as feasibility for implementing green building project. In addition, the suggested model assumed governmental guarantees for the increased cost, but private guarantees seem to be feasible as well because of the promising value of the guarantee from CER. To do this, certification of Clean Development Mechanisms (CDMs) for green buildings must be obtained.

This report studies the advantages and disadvantages of a separate financial market for the environmental advantages in the production of electricity from renewable energy sources. This market solution is evaluated against other financial systems used to promote the production of green electricity. By starting from a general equilibrium model for the green certificate market, the report discusses how the adaptation in the certificate market is influenced by changes in the market conditions. The certificate market is combined with a quota market for carbon dioxide, with and without international trade with electricity and certificate and market power in the production of electricity from renewable energy sources

Performance or marketing benefits? The case of LEED certification.

Matisoff, Daniel C; Noonan, Douglas S; Mazzolini, Anna M

2014-01-01

Green building adoption is driven by both performance-based benefits and marketing based benefits. Performance based benefits are those that improve performance or lower operating costs of the building or of building users. Marketing benefits stem from the consumer response to green certification. This study illustrates the relative importance of the marketing based benefits that accrue to Leadership in Energy and Environmental Design (LEED) buildings due to green signaling mechanisms, specifically related to the certification itself are identified. Of course, all participants in the LEED certification scheme seek marketing benefits. But even among LEED participants, the interest in green signaling is pronounced. The green signaling mechanism that occurs at the certification thresholds shifts building patterns from just below to just above the threshold level, and motivates builders to cluster buildings just above each threshold. Results are consistent across subsamples, though nonprofit organizations appear to build greener buildings and engage in more green signaling than for-profit entities. Using nonparametric regression discontinuity, signaling across different building types is observed. Marketing benefits due to LEED certification drives organizations to build "greener" buildings by upgrading buildings at the thresholds to reach certification levels.

Green certificate system for heating - principal and practical challenges

International Nuclear Information System (INIS)

Eldegard, Tom

2002-01-01

A certificate system with an obligation to buying is a very relevant instrument in energy policy in order to stimulate the implementation of new renewable energy sources. This solution is widely supported; it is being institutionalized in many countries, especially in Europe and in the electricity sector, and the heating sector is soon to follow. This report discusses the broad lines of a possible green certificate system for the heating sector in Norway and concludes that it is might well be linked with a similar system for the electricity sector. For Norway, an isolated certificate system for the electricity sector would not be cost-effective. This is because this system would emphasize relatively expensive renewable electric energy rather than utilizing the large potential for replacing the electric heating of buildings with much cheaper renewable heat

Accounting Changes on Green Certificates in Romania

Full Text Available The purpose of green certificates is to get more renewable electric energy into the energy market at the expense of traditional energy, which in most countries is based on fossil fuel. These renewable technologies are too expensive to enter the market on commercial terms. A key feature of the scheme is that producers of energy based on new renewable energy sources receive certificates from the authorities, proportional to their output. The users of electric energy are required to buy a certain amount of these certificates when they buy electricity. Green certificates may in principle contribute to a reduction of the production of traditional energy.

Thirty years of public health research have demonstrated that improved indoor environmental quality is associated with better health outcomes. Recent research has demonstrated an impact of the indoor environment on cognitive function. We recruited 109 participants from 10 high-performing buildings (i.e. buildings surpassing the ASHRAE Standard 62.1-2010 ventilation requirement and with low total volatile organic compound concentrations) in five U.S. cities. In each city, buildings were matched by week of assessment, tenant, type of worker and work functions. A key distinction between the matched buildings was whether they had achieved green certification. Workers were administered a cognitive function test of higher order decision-making performance twice during the same week while indoor environmental quality parameters were monitored. Workers in green certified buildings scored 26.4% (95% CI: [12.8%, 39.7%]) higher on cognitive function tests, controlling for annual earnings, job category and level of schooling, and had 30% fewer sick building symptoms than those in non-certified buildings. These outcomes may be partially explained by IEQ factors, including thermal conditions and lighting, but the findings suggest that the benefits of green certification standards go beyond measureable IEQ factors. We describe a holistic "buildingomics" approach for examining the complexity of factors in a building that influence human health.

The political economy of international green certificate markets

Soederholm, Patrik

2008-01-01

This paper analyzes the political economy of establishing bilateral trade in green certificate markets as one step towards harmonization of European green electricity support systems. We outline some of the economic principles of an integrated bilateral green certificates market, and then discuss a number of issues that are deemed to be critical for the effectiveness, stability and legitimacy of such a market. By drawing on some of the lessons of the fairly recent intentions to integrate a future green certificate market in Norway with the existing Swedish one, we highlight, exemplify and discuss some critical policy implementation and design issues. These include, for instance, the system's connection to climate policy targets, the role of other support schemes and the definition of what green electricity technologies should be included. Furthermore, the establishment of an international market presumes that the benefits of renewable power (e.g., its impacts on the environment, diversification of the power mix, self-sufficiency, etc.) are approached and valued from an international perspective rather than from a national one, thus implying lesser emphasis on, for instance, employment and regional development impacts. A bilateral green certificate system thus faces a number of important policy challenges, but at the same time it could provide important institutional learning effects that can be useful for future attempts aiming at achieving greater policy integration in the European renewable energy sector

Green building design is becoming broadly adopted, with one green building standard reporting over 3.5 billion square feet certified to date. By definition, green buildings focus on minimizing impacts to the environment through reductions in energy usage, water usage, and minimizing environmental disturbances from the building site. Also by definition, but perhaps less widely recognized, green buildings aim to improve human health through design of healthy indoor environments. The benefits related to reduced energy and water consumption are well-documented, but the potential human health benefits of green buildings are only recently being investigated. The objective of our review was to examine the state of evidence on green building design as it specifically relates to indoor environmental quality and human health. Overall, the initial scientific evidence indicates better indoor environmental quality in green buildings versus non-green buildings, with direct benefits to human health for occupants of those buildings. A limitation of much of the research to date is the reliance on indirect, lagging and subjective measures of health. To address this, we propose a framework for identifying direct, objective and leading "Health Performance Indicators" for use in future studies of buildings and health.

Acoustical case studies of three green buildings

2005-04-01

Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

Current experience concerning Romanian green certificates market functioning

The renewable energy sources are promoted by their beneficial use, namely: - diversification of energy sources for producing electric power; - reduction of pollution produced by fossil fuel burning; - reduction of gas releases producing the greenhouse effects, etc. Currently, most of the renewable energy sources cannot concur on electric power free market because of the high costs of implied investments. To ensure an efficient use of renewable energy sources in electricity production and to maintain the installations implied on the electric power market, it is necessary to implement a system able to produce an output greater than that obtained from electric energy selling. The Romanian Government chose to promote the electric energy production by renewable energy sources by using the green certificate trading system. This system ensures the progress in developing the technologies employed in electric energy production from renewable energy sources and, at the same time the costs implied by their promotion can be adjusted by market mechanisms what will reduce the effects upon the electric energy consumers. The paper presents the legislation frame existing in Romania for promoting the electric energy produced from renewable energy sources, the green certificate trading system applied in Romania, as well as, the role shared by the entities implied in operation and development of the system. In November 2005, a first transaction with green certificates on controlled green certificate market in Romania took place. Analyzed is the evolution of the green certificate market registered so far from its inception, as well as, the lessons learned so far from the experience acquired

Human Factors in Green Office Building Design: The Impact of Workplace Green Features on Health Perceptions in High-Rise High-Density Asian Cities

2016-10-01

Full Text Available There is a growing concern about human factors in green building, which is imperative in high-rise high-density urban environments. This paper describes our attempts to explore the influence of workplace green features (such as green certification, ventilation mode, and building morphology on health perceptions (personal sensation, sensorial assumptions, healing performance based on a survey in Hong Kong and Singapore. The results validated the relationship between green features and health perceptions in the workplace environment. Remarkably, participants from the air-conditioned offices revealed significant higher concerns about health issues than those participants from the mixed-ventilated offices. The mixed-ventilation design performs as a bridge to connect the indoor environment and outdoor space, which enables people to have contact with nature. Additionally, the preferred building morphology of the workplace is the pattern of a building complex instead of a single building. The complex form integrates the configuration of courtyards, podium gardens, green terrace, public plaza, and other types of open spaces with the building clusters, which contributes to better health perceptions. This research contributes to the rationalization and optimization of passive climate-adaptive design strategies for green buildings in high-density tropical or subtropical cities.

The problem of the legal nature of Green Certificates in the Italian legal system

International Nuclear Information System (INIS)

Colcelli, Valentina

2012-01-01

Green Certificates are usually described as negotiable instruments or commercial papers. The Italian legal system identifies Green Certificates as rights but, due to the ambiguity of the definition, their juridical nature remains uncertain. This reverberates on the functioning of the Green Certificates market and on the enforcement of the relevant norms. This paper discusses the actual legal nature of Green Certificates in Italy and concludes that they should be regarded as goods. This means that private law instruments apply in their market transactions, with consequent implications on the policy side. - Highlights: ► A definition of Green Certificates in the Italian legal system is provided. ► Green Certificates are not Credit Instruments. ► However, they may be negotiated separately from the energy they represent. ► Green Certificates are goods, which relate to new properties.

Green certificates will lead to increased electric power production

International Nuclear Information System (INIS)

Lind, Oddvar

2004-01-01

The implementation of green certificates will lead to increased electricity production from renewable energy sources and less risk of price crises. For the time being, a common market for green certificates will be established with Sweden from January 1, 2006. It is possible to realise a ''compulsory total quota'' of 20 TWh by 2016. Green certificates will imply a premium on the electricity bill. However, the quota system will imply increased power generation, which in turn tends to lower the price. Norway should in principle follow Sweden's definition of renewable energy: all new hydroelectric power, wind power, solar energy, wave and tidal power, biomass energy, and energy recovery. The certificate regime will apply to new investments in renewable power production. However, it would be natural to include the established renewable power production that is currently receiving support. Some critics fear that the consumers rather than the authorities will subsidize the production of green power. The point is being made that central EU countries may save great sums by investing in renewable energy in Norway

Green Buildings in Singapore; Analyzing a Frontrunner’s Sectoral Innovation System

Directory of Open Access Journals (Sweden)

Vidushini Siva

2017-05-01

Full Text Available The building sector in Singapore consumes up to half of the nation’s total energy. The government has therefore been urging the transformation of the industry by targeting 80% of all buildings to be green-certified by 2030. Thus far, Singapore has done relatively well, and is widely viewed as frontrunner in this respect. This paper addresses the question: what are the benefits and limitations of Singapore’s sectoral innovation system in spurring an energy transition in the building sector, in particular by up-scaling the use of green building technology? The Sectoral Innovation Systems (SIS theoretical framework was used to analyze the Singapore case. Four SIS components were assessed: technological regime, market demand, actor interactions and networks, and institutional framework. The benefits of Singapore’s sectoral innovation system identified in the analysis basically concern aspects of all of the four elements of SIS. Particular success factors concerned the launching of an integrated strategy to support green building innovations (i.e., the Green Mark policy scheme, implementing support policies, and setting up test beds. Furthermore, a masterplan to engage and educate end-users was implemented, knowledge exchange platforms were set up, regulations on the use of efficient equipment in buildings were issued, and standards and a certification system were adopted. The results also shed light on key barriers, namely, the reluctance of building users to change their habits, ineffective stakeholder collaboration, and green buildings innovation support coming from the government only. Measures in place have been moderately effective.

Building the green way.

Science.gov (United States)

Lockwood, Charles

2006-06-01

Just five or six years ago, the term "green building" evoked visions of barefoot, tie-dyed, granola-munching denizens. There's been a large shift in perception. Of course, green buildings are still known for conserving natural resources by, for example, minimizing on-site grading, using alternative materials, and recycling construction waste. But people now see the financial advantages as well. Well-designed green buildings yield lower utility costs, greater employee productivity, less absenteeism, and stronger attraction and retention of workers than standard buildings do. Green materials, mechanical systems, and furnishings have become more widely available and considerably less expensive than they used to be-often cheaper than their standard counterparts. So building green is no longer a pricey experiment; just about any company can do it on a standard budget by following the ten rules outlined by the author. Reliable building-rating systems like the U.S. Green Building Council's rigorous Leadership in Energy and Environmental Design (LEED) program have done much to underscore the benefits of green construction. LEED evaluates buildings and awards points in several areas, such as water efficiency and indoor environmental quality. Other rating programs include the UK's BREEAM (Building Research Establishment's Environmental Assessment Method) and Australia's Green Star. Green construction is not simply getting more respect; it is rapidly becoming a necessity as corporations push it fully into the mainstream over the next five to ten years. In fact, the author says, the owners of standard buildings face massive obsolescence. To avoid this problem, they should carry out green renovations. Corporations no longer have an excuse for eschewing environmental and economic sustainability. They have at their disposal tools proven to lower overhead costs, improve productivity, and strengthen the bottom line.

Green energy in Europe: selling green energy with green certificates

International Nuclear Information System (INIS)

Ouillet, L.

2002-01-01

Sales of green power products are booming in Europe: 50,000 customers in the United Kingdom, 775,000 in the Netherlands and 300,000 in Germany. Laws of physics are however formal: the way in which electricity flows within the grid does not allow suppliers to assure customers that they are directly receiving electricity produced exclusively from renewable energy sources. What are marketers selling their customers then? Laetitia Ouillet, Greenprices, takes a closer look and focuses on the potential of selling green energy in the forms of renewable energy certificates.

Market power in interactive environmental and energy markets: the case of green certificates

International Nuclear Information System (INIS)

Amundsen, Eirik S.; Nese, Gjermund

2004-01-01

Markets for environmental externalities are typically closely related to the markets causing such externalities, whereupon strategic interaction may result. Along these lines, the market for Green Certificates is strongly interwoven in the electricity market as the producers of green electricity are also the suppliers of Green Certificates. In this paper, we formulate an analytic equilibrium model for simultaneously functioning electricity and Green Certificate markets, and focus on the role of market power. We consider two versions of a Nash-Cournot game: a standard Nash-Cournot game where the players treat the market for Green Certificates and the electricity market as separate markets; and a Nash-Cournot game with endogenous treatment of the interaction between the electricity and Green Certificate markets with conjectured price responses. One result is that a certificate system faced with market power may collapse into a system of per unit subsidies, as the producers involved start to game on the joint functioning of markets.

Feed-in tariff and tradable green certificate in oligopoly

2010-01-01

Feed-in tariff (FIT) and tradable green certificate (TGC) schemes are studied in a formal model and numerical example using the UK data. We find that if the markets were perfectly competitive, then feed-in tariff and the certificate price would be the same. However, when the markets are imperfect, they are generally different. While both the tariff and certificate price fluctuate around the difference between the costs of green and black energy, the tariff deviates more from the cost difference than the certificate price. The supplies of both black and green energy under FIT are higher than TGC, obviously as a result of subsidies. A troubling outcome is that the total energy supply increases under FIT as the renewables quota increases, which can negate other measures to mitigate climate changes such as demand management. Finally, using the data from the UK market, we find that social welfare under TGC is consistently higher than FIT for a wide range of values of the parameters.

Cai, Jia-wei; Sun, Jian

2014-01-01

With more and more emphasizes on the environment and resources, the concept of green buildings has been widely accepted. Building materials are vectors of architectures, only if green building materials and related technical means are used, can we construct green buildings to achieve the purpose of energy conservation and environmental protection. This paper introduces the relationship between green building materials and green buildings, the current situation of green building materials in China, as well as the measures to accelerate the development of green building materials

2006-01-01

The promotion of electricity produced from renewable energy sources, RES, represents an imperative of the present period of time justified by the environment protection, the increasing of energy independence against the imports - through the diversification of energy supply sources - as well as economic and social reasons. The Directive 2001/77/EC of the European Parliament and the Council on the promotion of electricity produced from renewable energy sources in the internal electricity market represents the first step of European Union in complying with the Kyoto targets of reducing the greenhouse gases. Romania was one of the first EU candidate countries transposing the Directive 2001/77/EC provisions into its own legislation (see Governmental Decision - GD no. 443/2003 amended by GD no.958/2005). The indicative target for 2010 was fixed at 33%, representing the share of E-RES in the gross national electricity consumption. The contents of the paper is as follows: 1. Introduction; 2. Legal Framework; 2.1. Primary legislation on RES; 2.2. Secondary legislation on RES; 3. The E-RES Promotion system in Romania; 4. The Operation of green certificates market; 4.1. Setting up the mandatory quotas; 4.2. Qualify the E-RES; 4.3. Issuing the green certificates; 4.4. Trading the green certificates; 4.5. Competencies and attributions regarding the organisation and operation of the green certificates market; 4.6. The allocation of the money obtained from suppliers for non-purchased green certificates to fulfil the imposed mandatory quota; 5. The results of the GCs transactions on the centralized market; 6. Conclusion. The paper concludes by underlining that: - the legal framework of regulation is complete and it ensures the operating of promotion system of E-RES; - eighteen suppliers did not comply with their annual mandatory quota (752 green certificates); - the Romanian indicative target for 2010 regarding the share of E-RES in the gross national electricity consumption was

Interactions between the power and green certificate markets

International Nuclear Information System (INIS)

Jensen, S.G.; Skytte, K.

2002-01-01

The current trend of liberalising the power markets is combined with ambitious deployment plans for power production based on renewable energy supplies. A new policy scheme to ensure this extension has been developed in the form of a green certificate system, with a politically determined target of deployment. In such a system, producers of renewably based electricity receive tradable certificates in proportion to the electricity they produce. The producer can thereby sell these certificates and receive additional revenue apart from the power price. This paper studies the price and consumption effects of such a system. With a simple model we show that the effects are ambiguous. This ambiguity is caused by the interaction between the two markets. Therefore, the green certificate system is difficult to manage if the State has parallel energy targets, such as a desired deployment of renewably based energy and a stabilisation or reduction of the energy consumption. In addition, this complicates the regulation through a deployment target of renewably based power production, as the regulator has to be aware of the different effects, which follow a specific target. Until now, these effects have not been considered in the analyses of the green certificate system when introducing the system, even though it might have considerable consequences for the success of the system.

Policy Pathways: Energy Performance Certification of Buildings

Energy Technology Data Exchange (ETDEWEB)

NONE

2010-07-01

Improving energy efficiency is one of the most effective measures to address energy security, climate change and economic objectives. The Policy Pathways series can help countries capture this potential by assisting with the implementation of the 25 energy efficiency policy recommendations that were published by the International Energy Agency (IEA) in 2008. This policy pathway on energy performance certification of buildings is the second in the series. It aims to provide a 'how-to' guide to policy makers and relevant stakeholders on the essential elements in implementing energy performance certification of buildings programmes. Energy performance certification of buildings is a way to rate the energy efficiency of individual buildings -- whether they be residential, commercial or public. It is a key policy instrument that can assist governments in reducing energy consumption in buildings. This policy pathway showcases experiences from countries around the world to show examples of good practice and delivers a pathway of ten critical steps to implement energy performance certification of buildings programmes.

The effect of financial constraints, technological progress and long-term contracts on tradable green certificates

International Nuclear Information System (INIS)

Agnolucci, Paolo

2007-01-01

Tradable green certificates (TGCs) have recently become a diffuse instrument to support renewable electricity in OECD countries. Although it is perhaps too early to draw a conclusive judgement on the effectiveness of this instrument in increasing renewable capacity and decreasing the price of certificates, one view in the literature maintains that long-term contracts are of particular importance for TGCs to be effective. This paper contributes to this debate by analysing how financial constraints and technological progress can induce investors to hold pessimistic expectations of their ability to sell green certificates and still make a profit. Clearly, these expectations will prevent investors from building new capacity to fulfil the quota comprised in TGCs and will keep the price of certificates traded in the market high. As this kind of expectation is not influenced by most design features of TGCs, one can conclude that long-term contracts are particularly important in determining the effectiveness and cost-effectiveness of these instruments. Some attention should therefore be paid to the features of the TGCs, which induce obliged parties to offer long-term contracts to renewable generators. (author)

Green certificates and greenhouse gas emissions certificates - Instruments of the liberalized electricity market in Romania

Matei, Magdalena; Salisteanu, Cornel; Enescu, Diana; Ene, Simona; Matei, Lucian; Marinescu, Mihai

2006-01-01

Governmental Decision No. 443/2003 and GD 1892 / 2004 aimed to the harmonization of the Romanian legislative framework with EU Directive 2001/77/EC which purposes to promote an increasing in the contribution of RES to electricity production in the internal market for electricity. In Romania's case green certificate system was adopted with mandatory quotas for suppliers as a national target for 2010 of 33 % of total consumption to be covered by electricity produced from renewable energy sources. The annual maximum and minimum value for Green Certificates trading is 24 Euro/certificate and 42 Euro/certificate, respectively. Suppliers are obliged to buy yearly a number of Green certificates equal with the mandatory quota multiplied with the amount of electricity sold yearly to their final consumers. The additional price received for the Green Certificates sold is determined on a parallel market, separated from the electricity market, where the environmental benefits of the 'clean' electricity production are traded. The regulator can modify these quotas established by Government Decision when the installed capacity in the power plants which use RES cannot secure the demand of Green Certificates; This system was introduced in November 2005. The number of issued green certificates in 2005 was only 345, so by ANRE Order no. 46 / 2005, the mandatory quota for 2005 was reduced at 2.6% from legal quota established for 2005. In the first month of 2006 5997 Green Certificates were sold at the price of 146 RON. Emissions trading is the most compatible flexible mechanisms of Kyoto Protocol with deregulated electricity markets. The Directive 2003/87/CE referring at CO 2 emission trading within Europe came into force and till 31 March 2004 all the countries had to present to the Commission their national plan to comply with Directive's rules. There is great uncertainty worldwide on how GHG emissions reduction and trading schemes will develop. Previous visions of a single (Kyoto

Green Building Pro-Environment Behaviors: Are Green Users Also Green Buyers?

Directory of Open Access Journals (Sweden)

Xiaohuan Xie

2017-09-01

Full Text Available Pro-environment behaviors play a key role in advancing the development of green buildings. This study investigated the link between two green building pro-environment behaviors that require dissimilar resources: energy savings that do not require money in order to be more environmentally friendly and willingness to pay that involves economic resources including spending money in order to be more environmentally friendly. This study points out that the two pro-environment behaviors can be positively linked to each other. People who behave in an environmentally friendly manner at work would also be likely to pay an extra cost for a green building when buying a new home. The consistency of the two pro-environment behaviors can be explained by their common environmental beliefs: limits to growth and eco-crisis. The green building movement should prioritize pro-environmental behaviors and associated environmental beliefs to support green building policies, guidelines, and tools.

The Italian Green Certificates market between uncertainty and opportunities

International Nuclear Information System (INIS)

Lorenzoni, Arturo

2003-01-01

With the overall reform of the electricity industry in 1999, Italy has started the implementation of a new support mechanism for renewable energy sources that is based upon a Green Certificates market. Such certificates will be delivered for 8 years for electricity production to renewable power plants commissioned after 31 March 1999. All the electricity production based on non-renewable energy sources and import have an obligation to cover 2% of its total with Green Certificates. This support mechanism is open to foreign production, but only from countries with reciprocal opportunities for Italian production. The new market has formally started on January 2002, even if some important rules have not yet been defined. This paper describes the new support mechanism, investigates the critical aspects for its activation and shows some possible trends for the quantity of the supplied certificates and their prices in the coming years

This report studies the advantages and disadvantages of a separate financial market for the environmental advantages in the production of electricity from renewable energy sources. This market solution is evaluated against other financial systems used to promote the production of green electricity. By starting from a general equilibrium model for the green certificate market, the report discusses how the adaptation in the certificate market is influenced by changes in the market conditions. The certificate market is combined with a quota market for carbon dioxide, with and without international trade with electricity and certificate and market power in the production of electricity from renewable energy sources.

The availability of wind energy certificates in Pennsylvania's retail electricity market has made a critical difference in the economic feasibility of developing 140 MW of new wind energy projects in the region. Certificates offer important benefits to both green power suppliers and buyers by reducing transaction barriers and thus lowering the cost of renewable energy. Buyers also benefit through the increased flexibility offered by certificate products. The experience described in this paper offers important insights for selling green power certificates and achieving new wind energy development in other areas of the country.

The development of a green certificate market

International Nuclear Information System (INIS)

Morthost, P.E.

2000-01-01

Liberalizing the electricity industry and attempting to reduce the emissions of greenhouse gases are the two dominant trends in European energy policy. The last-mentioned issue might require the contribution from renewable energy technologies, but at present most renewables cannot compete on their own with conventional technologies. Thus, it can be expected that if renewables must compete solely on market conditions alone this will slow down or even halt the development of new renewable capacity. One model in which additional payments to renewable technologies are generated is based on the development of a separate green market. In Holland, a voluntary green certificate has existed since the beginning of 1998. In Denmark a comprehensive restructuring of the legislation for the electric power industry has just been completed, including the framework for developing a separate green market for renewable electricity production. The main objectives of introducing this type of electricity market in Denmark is to secure the development of renewable energy technologies (including contributions to greenhouse gas reductions), while at the same time releasing the Government from the (by now) quite heavy burden of subsidising renewable technologies. Finally, a green market will make it possible for these renewable technologies to be partly economically compensated for the environmental benefits, which they generate compared to conventional power production. With the recent Danish legislation as starting point this paper analyzes possible ways to set up a green certificate market, treating as well some of the consequences produced when the market is actually functioning. The analysis is applicable for all renewable technologies, but special attention is given to wind power. (author)

Fungal Microbiomes Associated with Green and Non-Green Building Materials.

Water-damaged buildings can lead to fungal growth and occupant health problems. Green building materials, derived from renewable sources, are increasingly utilized in construction and renovations. However, the question as to what fungi will grow on these green compared to non-green materials, after they get wet, has not been adequately studied. By determining what fungi grow on each type of material, the potential health risks can be more adequately assessed. In this study, we inoculated green and non-green pieces of ceiling tile, composite board, drywall, and flooring with indoor dust containing a complex mixture of naturally occurring fungi. The materials were saturated with water and incubated for two months in a controlled environment. The resulting fungal microbiomes were evaluated using ITS amplicon sequencing. Overall, the richness and diversity of the mycobiomes on each pair of green and non-green pieces were not significantly different. However, different genera dominated on each type of material. For example, Aspergillus spp. had the highest relative abundance on green and non-green ceiling tiles and green composite boards, but Peniophora spp. dominated the non-green composite board. In contrast, Penicillium spp. dominated green and non-green flooring samples. Green gypsum board was dominated by Phialophora spp. and Stachybotrys spp., but non-green gypsum board by Myrothecium spp. These data suggest that water-damaged green and non-green building materials can result in mycobiomes that are dominated by fungal genera whose member species pose different potentials for health risks.

Civilizational challenges have questioned the status quo of energy and material consumption by humans. From the built environment perspective, a response to these challenges was the creation of green buildings. Although the revolutionary capacity of the green building movement has elevated the expectations of new commercial construction, its rate of implementation has secluded the majority of the population from its benefits. Beyond reductions in energy usage and increases in market value, the main strength of green buildings may be the procurement of healthier building environments. Further pursuing the right to healthy indoor environments could help the green building movement to attain its full potential as a transformational public health tool. On the basis of 40 years of research on indoor environmental quality, we present a summary of nine environment elements that are foundational to human health. We posit the role of green buildings as a critical research platform within a novel sustainability framework based on social-environmental capital assets.

Buildings consume nearly 40% of primary energy production globally. Certified green buildings substantially reduce energy consumption on a per square foot basis and they also focus on indoor environmental quality. However, the co-benefits to health through reductions in energy and concomitant reductions in air pollution have not been examined.We calculated year by year LEED (Leadership in Energy and Environmental Design) certification rates in six countries (the United States, China, India, Brazil, Germany, and Turkey) and then used data from the Green Building Information Gateway (GBIG) to estimate energy savings in each country each year. Of the green building rating schemes, LEED accounts for 32% of green-certified floor space and publically reports energy efficiency data. We employed Harvard's Co-BE Calculator to determine pollutant emissions reductions by country accounting for transient energy mixes and baseline energy use intensities. Co-BE applies the social cost of carbon and the social cost of atmospheric release to translate these reductions into health benefits. Based on modeled energy use, LEED-certified buildings saved $7.5B in energy costs and averted 33MT of CO 2 , 51 kt of SO 2 , 38 kt of NO x , and 10 kt of PM 2.5 from entering the atmosphere, which amounts to $5.8B (lower limit = $2.3B, upper limit = $9.1B) in climate and health co-benefits from 2000 to 2016 in the six countries investigated. The U.S. health benefits derive from avoiding an estimated 172-405 premature deaths, 171 hospital admissions, 11,000 asthma exacerbations, 54,000 respiratory symptoms, 21,000 lost days of work, and 16,000 lost days of school. Because the climate and health benefits are nearly equivalent to the energy savings for green buildings in the United States, and up to 10 times higher in developing countries, they provide an important and previously unquantified societal value. Future analyses should consider these co-benefits when weighing policy

Situating CASBEE, a Japanese-made unique building rating and certification system, within a broader context

Directory of Open Access Journals (Sweden)

Raymond J. Cole

2014-06-01

Full Text Available An underlying premise of the voluntary assessments and certifications offered by existing major building performance assessment systems is that if the market is provided with improved information and mechanisms, a discerning client group can and will provide leadership in environmental responsibility, and that others will follow suit to remain competitive. Building environmental ratings have provided building owners with a credible and objective means to communicate to prospective tenants the environmental qualities of the building they are leasing and, by emphasizing more demanding performance goals and the benefits over typical practice, have begun to reframe expectations. Over the past twenty plus years, building environmental assessment has matured into a legitimate area of research and study. Assessment tools in use worldwide generally fall into two general categories: 1 Those developed by an organization within a country that maintains and manages it and provides the associated educational support and operational infrastructure. All the major recognized systems – BREEAM, LEED, CASBEE, Green Star in Australia, etc., – fall into this category. 2 Those developed by academics either for research purposes or in hopes that they could become a certification system but to date have yet to gain widespread adoption in their respective countries.

Certification of building thermographers: experiences after three courses

Kauppinen, Timo; Hekkanen, Martti; Paloniitty, Sauli; Krankka, Juha

2006-04-01

The certification procedure of building thermographers was started in 2003, even though thermography has been used in Finland in building survey since late 70's. There has been about a 25 years' unorganized and more or less wild period, without any generally accepted rules for interpretation, as well as how to order thermography services, how to report the results, how to do the practical work in the buildings etc. The service was provided by consultants with varied backgrounds. More operators have come into the market and building developers and contractors have begun to use thermography for quality control in new building and in renovation planning. In the year 2004 various organizations in building trade launched a pilot project to certificate building thermographers. The structure and the topics of the course were introduced in Thermosense 2005. By the end of the year 2005 the third course was completed. From the beginning of the procedure to the end of the third course about 40 persons have received a certificate. During the certification process, two guidelines have been published, as part of RT (Building Information) - files: instructions for ordering, for practical field work and for reporting of thermography survey in buildings. The guidelines also contain basics for interpretation. The interpretation is consistent with the other existing directions (building codes etc). At the turn of 2005 - 2006 a new book of building thermography was published. There is still lack of comprehensive as well as unambiguous rules for interpretation. In the paper we will present experiences on the courses, the main problems posed to the participants and findings during the last two - three years' field work. We will also introduce briefly the structure and content of the guidelines and an example how to use thermography as a tool of quality control in new building. The case studies are new one-family houses in a housing fair and exhibition area in the city of Oulu.

Indoor air quality in green buildings: A case-study in a residential high-rise building in the northeastern United States.

Improved indoor air quality (IAQ) is one of the critical components of green building design. Green building tax credit (e.g., New York State Green Building Tax Credit (GBTC)) and certification programs (e.g., Leadership in Energy & Environmental Design (LEED)) require indoor air quality measures and compliance with allowable maximum concentrations of common indoor air pollutants. It is not yet entirely clear whether compliance with these programs results in improved IAQ and ultimately human health. As a case in point, annual indoor air quality measurements were conducted in a residential green high-rise building for five consecutive years by an industrial hygiene contractor to comply with the building's GBTC requirements. The implementation of green design measures resulted in better IAQ compared to data in references of conventional homes for some parameters, but could not be confirmed for others. Relative humidity and carbon dioxide were satisfactory according to existing standards. Formaldehyde levels during four out of five years were below the most recent proposed exposure limits found in the literature. To some degree, particulate matter (PM) levels were lower than that in studies from conventional residential buildings. Concentrations of Volatile Organic Compounds (VOCs) with known permissible exposure limits were below levels known to cause chronic health effects, but their concentrations were inconclusive regarding cancer health effects due to relatively high detection limits. Although measured indoor air parameters met all IAQ maximum allowable concentrations in GBTC and applicable LEED requirements at the time of sampling, we argue that these measurements were not sufficient to assess IAQ comprehensively because more sensitive sampling/analytical methods for PM and VOCs are needed; in addition, there is a need for a formal process to ensure rigor and adequacy of sampling and analysis methods. Also, we suggest that a comprehensive IAQ assessment should

The vast increase of energy consumption, global warming and the harm they cause to the environment, emerge to be a major obstruction that distresses the world today. This review paper views one of the methods that the world focused on as means of reducing the environmental harms and that is, through green building, or in more common words sustainable buildings. Those means, covers the exercising of a wide range of applications including merging of new and specific technologies in which through fulfilling its basis, the process of evaluation of the building takes place in terms of its harmony with the environment, reduction of energy consumption, and the reduction of the environmental problems caused by the building life cycle starting from defining of location, design of the building, operation, maintenance, repairing and up to the renewal of the building. Despite the significance of green building, no profit nor implementations has yet been made in Libya. The latter is due to the lack of awareness by many Libyan social groups. From here, the idea behind this paper crystallized. It aims to spread and enhance the knowledge and techniques of green building. It also penetrates into the green building features and advantages that are considered to be a preliminary step to start its application in a wide range coinciding with the grand progress that the country has witnessed in the field of construction and housing. This paper concludes that it is possible to reduce energy consumption and the harm it causes to the environment after the implementation and merging of green building techniques and should be applied on a large scale covering the whole country.(author)

Simultaneous attainment of energy goals by means of green certificates and emission permits

International Nuclear Information System (INIS)

Jensen, Stine Grenaa; Skytte, Klaus

2003-01-01

We discuss the analytical effects of introducing emission permits and green certificates and the corresponding quotas as regulatory mechanisms to, respectively, reduce emissions from electricity production and ensure a certain deployment of renewable energy. The different case studies in this paper show that both instruments can be used in order to reach an emission goal or a goal of renewable energy. However, the combination of these instruments and the way they are used, is shown to be important for the price faced by consumers. It is shown that the effect on the consumer price is not an unambiguous increase with the introduction of a green quota. There is a choice between quotas leading to a lower consumer price and quotas leading to a higher consumer price. As a result of this it is shown that it is always optimal to reach a renewable energy deployment goal by the use of green certificates. However, to reach an emission goal it is sometimes most favourable, with respect to consumer prices, to use green certificates and sometimes to use emission permits

Full Text Available The economy has developed and specialized itself in different fields of activity and great economists have had the possibility to observe the polluting effects of mankind’s activity (which nowadays develops its activity within some local, state and world business enterprises heading at present towards a globalization of the economic activity. Even though the harmful influence of the economic agent's activity on the environment has been noticed for over a century now, only in the last decades new span concepts and actions appeared, such as: sustainable development and national and international policies regarding the environment.Sustainable development pursues and tries to find a stable theoretical framework for making decisions in any situation in which a man/environment type relationship is found (whether it is about the environment or the economic or social medium and it constitutes the main objective of sustainable development. At present, the concept comprises both the solving of the ecological crisis ensuring the quality of the environment and that of life quality in its complexity, including social and economic aspects. One of these solutions is the introduction of the "green certificates" concept. Its emergence led to the appearance of a competition in the field of energy production from renewable resources. Each green certificate must contain the following information: the quantity of produced energy and its source, a unique registration number and other additional information, if it is required. The validity period of the green certificate is the date on which the energy was already produced and consumed.

Green certificate trading in the Netherlands in the prospect of the European electricity market

International Nuclear Information System (INIS)

Dinica, Valentina; Arentsen, Maarten J.

2003-01-01

The support system for green electricity in the Netherlands has been one of the most complex and complicated systems across Europe. A voluntary trade of green certificates--or green labels--was one of the schemes used in the policy models of the 1990s. The liberalization of the electricity market has attracted substantial changes in the degree and nature of commitment by energy companies and political authorities for renewable electricity. In 2001, a new mechanism for the voluntary trade of green certificates has become operational, replacing the green label trade system one terminated in the end of 2000. This paper presents the two systems of green certificates' trade developed in the Netherlands and discusses their market stimulation potential in the very different economic and industrial circumstances that has surrounded each of them. The paper argues for a need to enable a support system that reduces investment risks as much as possible, and removes the residual, but still strong, institutional, administrative and social barriers for renewables' deployment. But before this, a clear governmental vision on the role of renewables in current energy supply systems is first needed, backed by a coherent policy and sufficient support along the economic dimension of renewables' market diffusion

Hedge, A; Dorsey, J A

2013-01-01

A retrospective post-occupancy evaluation survey of 44 occupants in two Leadership in Energy and Environmental Design (LEED) Platinum buildings on a US college campus is reported. The Internet survey covered a range of indoor environment and ergonomics issues. Results show that working in these buildings were a generally positive experience for their health, performance and satisfaction. However, in one building there were persistent issues of variability in air temperature, air freshness, air quality and noise that affected the perceived health and performance of the occupants. Although the buildings were energy-efficient and sustainable structures, ergonomics design issues were identified. Implications for the role of ergonomics in green buildings and in the US LEED rating system are discussed. This survey identified a number of ergonomics design issues present in the LEED Platinum energy-efficient and sustainable buildings that were studied. These results highlight the importance of integrating ergonomics design into green buildings as a component in the US LEED rating system.

Standardization of green building technologies for environment design

Directory of Open Access Journals (Sweden)

Benuzh Andrey

2016-01-01

Full Text Available The article describes the structure and field of standardization ISO / TC 205 “Building environment design”, provides examples of green building technologies. The main purpose of the article is to show the interaction between international ISO / TC 205 “Building environment design” and created in Russia in 2016 the Technical Committee of Standardization № 366 “Green technology of the build environment and green innovative products”. Both of these technical committees promote green building technologies for environment design, thereby deal with the negative impact on the environment and the reasons of global warming. Instead of buildings that attempt to suppress and overcome nature, why not design buildings that integrate with the environment, on every possible level? The international standardization work which ISO/TC 205 “Building environment design” performs seeks, in addition to lowering trade barriers for engineering design, to promote and facilitate the design of high performance buildings: higher performing as economic assets for their owners, higher performing as buildings that provide amenable indoor environment for their occupants, and higher performing with respect to resource utilization and environmental impact.

The interaction between electricity, heat and gas in a tradable green certificate system. Paper for the analysis phase of InTraCert

International Nuclear Information System (INIS)

Boots, M.G.; Schaeffer, G.J.; De Zoeten, C.

2001-08-01

The InTraCert project aims to explore the possibility of integrating the existing and planned Tradable Green Certificate (TGC) schemes in the European Union and, therefore, creating a plausible unified market for TGCs. In particular, attention was paid to the possibilities of integrating TGCs for green electricity, green heat and biogas. Specific issues at stake when taking green heat and biogas into account in a green certificate system were analyzed. The analysis shows that production-based issuing of certificates is preferred, although for practical reasons it is easier to start with grid-based (and 'electricity-only') certificates. Conversion between different certificates and units are of main concern when green heat and biogas are included in the system. The kWh seems to be a convenient unit to issue the certificates. It should be possible to exchange certificates for new certificates, i.e. 'redemption for conversion' (conversion of the certificates in parallel with the conversion of the physical energy flow), as opposed to the redemption of certificates to fulfil an obligation. Mandatory demand, or the obligation, should suitably be put on consumers and stated in general terms. The consumer may then decide on the preferred energy mix to fulfil his obligation. Countries may allow for the possibility to comply with the obligation using foreign certificates and restrict the import of TGCs that they judge to be unacceptable. However, for substantial international trade to take place, some harmonisation, e.g. for issuing certificates, is required. 6 refs

Green buildings: Implications for acousticians

Science.gov (United States)

Noble, Michael R.

2005-04-01

This presentation will deal with the practical implications of green design protocols of the US Green Building Council on interior acoustics of buildings. Three areas of particular consequence to acousticians will be discussed. Ventilation Systems: reduced energy consumption goals dictate reliance on natural cooling and ventilation using ambient air when possible. The consequent large openings in the building envelope to bring fresh air into rooms, and similar sized openings to transfer the mixed air out, can severely compromise the noise isolation of the rooms concerned. Radiant Cooling: the heavy concrete floors of buildings can be used as a thermal flywheel to lessen the cooling load, which forces the concrete ceilings to be exposed to the occupied rooms for heat transfer, and strictly limits the application of acoustical absorption on the ceilings. This challenges the room acoustics design. Green Materials: the LEED protocols require the elimination of potentially harmful finishes, including fibrous materials which may impact air quality or contribute to health problems. Since the backbone of sound absorption is glass and mineral fibres, this further challenges provision of superior room acoustics. Examples and commentary will be provided based on current and recent projects.

Full Text Available The concept of retrofitting an existing building towards green building was introduced to move towards greener development. This paper investigates the benefits of retrofitting an existing building to green building. The potential retrofit of the existing Sultan Ismail Parliament building was also determined and later the elements of the building to be retrofitted were proposed. The Sultan Ismail Parliament building is one of the newest development that serves as the Johor state administrative center under Iskandar Malaysia. Therefore, this paper focuses on whether the existing building has fulfilled all of the green building elements. A set of questionnaire was distributed to the targeted respondents who were the engineers, architects, technicians, staffs and those who were involved in the development of the Sultan Ismail Parliament building. A total of 60 respondents was involved. Based on the analyzed data, it shows that the existing building has fulfilled only one of the green building elements which is the Indoor Environmental Quality. The items that scored 3.5 and above mean index under this element include the daylight glare is not bothering, the ventilation in the building is adequate, inspections are done regularly, smoking regulation is implemented and the number of openings of windows and doors is sufficient. While it shows that other elements were only partially fulfilled. The criteria that achieved below 3.5 mean index values is considered to be the potential elements that could be used for future retrofitting initiative.

Assessment of Energy Credits in LEED-Certified Buildings Based on Certification Levels and Project Ownership

Directory of Open Access Journals (Sweden)

Asli Pelin Gurgun

2018-02-01

Full Text Available Compared to other categories, the Energy and Atmosphere category contributes the most to the maximum obtainable points in the Leadership in Energy and Environmental Design (LEED certification system. The objective of the study was to identify the extent to which project teams take advantage of the credits in the Energy and Atmosphere category of LEED. This study analyzes the performance of practitioners in achieving points in the Energy and Atmosphere credits of LEED-New Construction (NC 2009 for 1500 buildings that received LEED certification in the US. For a better understanding of the credit patterns, the differences in the performance of practitioners are investigated relative to certification levels and project ownership. Achievement in credits is calculated in terms of percent of maximum points (PMP, since the maximum achievable points differ for each credit. Practitioners’ achievements in the credits were ranked as follows: (1 enhanced commissioning, (2 optimized energy performance, (3 enhanced refrigerant management, (4 green power, (5 measurement and verification, and (6 on-site renewable energy. The largest achievement differences were observed in the on-site renewable energy credit. Concerning building ownership, investors were found to optimize mostly energy efficiency and on-site renewable energy, but to mostly skip enhanced refrigerant management. Performance in the measurement and verification credit was similar for all owner types, whereas investors performed differently from corporations, and government agencies in the enhanced commissioning credit. Practitioners who recognize these priorities and differences are expected to be better positioned to make sustainability-related decisions in building design and construction.

Evaluation of Water Efficiency in Green Building in Taiwan

Directory of Open Access Journals (Sweden)

Cheng-Li Cheng

2016-06-01

Full Text Available Low carbon policies, including those aimed at increasing water efficiency, have been adopted as a crucial strategy for combating global warming and climate change. The green building evaluation system used in Taiwan was first applied in 1999 and initially utilized a building’s water efficiency as the threshold index for determining the building’s environmental impact. Since 1999, more than a thousand buildings have been certified as green buildings using this evaluation system. The quantitative effects of water conservation efforts should be provided to policy makers as a form of positive feedback. To that end, the present study offers a calculation process for estimating the quantitative volume of water saved by practical green buildings. The baseline water usage for all kinds of buildings was determined to serve as the criterion for determining the water-saving efficiency of individual buildings. An investigation of the average water-saving rate from 2000 to 2013 for 1320 buildings certified as green buildings was also conducted to validate the estimation results and found that these green buildings saved an average of approximately 37.6% compared to the baseline water usage rate for all buildings. Water savings will inevitably follow from the use of water-saving appliances or water-saving designs for buildings. The proposed calculation process can be used to clarify the relationships between specific water-saving concepts and the real water usage efficiency of green buildings.

2017-12-01

A real estate development often produces negative impacts towards the environment such as the reduction of the ecological capacity in the site and its surroundings, energy exploitation, and excessive pollutant emission. To overcome these issues, the green building concept or approach has been adapted by several real estate businesses in Indonesia especially in the office sector. According to the data provided by GBCI in 2017, there are 17 buildings listed as a certified green building office in various levels. As what has been known, the green building approach results in the increase of price in the planning, construction and the building's maintenance. This paper will discuss about the research results regarding the effect of the green building approach towards the property value of office buildings especially in Jakarta. The research will be executed through the comparison method, which is the process of comparing office building that have already adapted the green building concept with the one that have not, or in other words, the conventional office buildings. Data gathering is done through observation and interviews with developers and building managers. The research results show that by adapting the green building approach for office buildings in Jakarta, the property value regarding the utility, scarcity, effective demands, and transferability aspect can increase.

Increasing population and over-consumption are placing unprecedented demands on agriculture and natural resources. The Earth is suffering from global warning and environmental destruction while our agricultural systems are concurrently degrading land, water, biodiversity, and climate on a global scale. For a sustainable future, green certification, e-commerce, and environment education can boost low-carbon economy with decreasing carbon emissions, but very few researches address them for the hotel industry. This research studies the performance impact of e-commerce, international hotel chain, local hotel chain, and green certification for carbon emission reductions of international tourist hotels of Taiwan. It reveals that, after a sufficiently long time, there is an improvement in the environmental and economic performance of the green-certified hotel group. In addition, it reveals that, as recommended by the operation policy, the international hotel chain group together with e-commerce has better performance than local hotel chain. It is also discussed how to sustain the continuing improvement in low-carbon performance of the hotel industry.

2017-12-01

The Local Government of Bandung city has stipulated a Green Building regulation through the Peraturan Walikota Number 1023/2016. Signed by the mayor in October 2016, Bandung became the first city in Indonesia that put green building as mandatory requirement in the building permit (IMB) process. Green Building regulation is intended to have more efficient consumption of energy and water, improved indoor air quality, management of liquid and solid waste etc. This objective is attained through various design method in building envelope, ventilation and air conditioning system, lighting, indoor transportation system, and electrical system. To minimize energy consumption of buildings that have large openings, sun shading device is often utilized together with low-E glass panes. For buildings in hot humid tropical climate, this method reduces indoor air temperature and thus requires less energy for air conditioning. Indoor air quality is often done by monitoring the carbon dioxide levels. Application of algae as part of building system façade has recently been introduced as replacement of large glass surface in the building façade. Algae are not yet included in the green building regulation because it is relatively new. The research will investigate, with the help of the modelling process and extensive literature, how effective is the implementation of algae in building façade to reduce energy consumption and improve its indoor air quality. This paper is written based on the design of ITB Innovation Park as an ongoing architectural design-based research how the algae-integrated building façade affects the energy consumption.

Building roof greening is a successful strategy for improving urban thermal environment. It is of theoretical interest and practical importance to study the effects of building roof greening on urban air quality in a systematic and quantitative way. In this study, we examine the effects of building roof greening on air quality in street canyons using a computational fluid dynamics (CFD) model that includes the thermodynamic energy equation and the transport equation of passive, non-reactive pollutants. For simplicity, building roof greening is represented by specified cooling. Results for a simple building configuration with a street canyon aspect ratio of one show that the cool air produced due to building roof greening flows into the street canyon, giving rise to strengthened street canyon flow. The strengthened street canyon flow enhances pollutant dispersion near the road, which decreases pollutant concentration there. Thus, building roof greening improves air quality near the road. The degree of air quality improvement near the road increases as the cooling intensity increases. In the middle region of the street canyon, the air quality can worsen when the cooling intensity is not too strong. Results for a real urban morphology also show that building roof greening improves air quality near roads. The degree of air quality improvement near roads due to building roof greening depends on the ambient wind direction. These findings provide a theoretical foundation for constructing green roofs for the purpose of improving air quality near roads or at a pedestrian level as well as urban thermal environment. Further studies using a CFD model coupled with a photochemistry model and a surface energy balance model are required to evaluate the effects of building roof greening on air quality in street canyons in a more realistic framework.

Cool roofs refer that maximize heat emission, and minimize the absorption of solar radiation energy, by applying high solar reflectance paints, or materials to roofs or rooftops. The application of cool roofs to existing buildings does not need to take structural issues into consideration, as rooftop greening, is an alternative that can be applied to existing buildings easily. This study installed a cool roofs on existing buildings, and evaluated the performances, using the results to propose certification standards for green remodeling, considering the cool roof-related standards.

Green building standards are significantly impacting modern construction practices. The resulting structures are more energy efficient, but their impact on occupant health has not been widely studied. To investigate a range of indoor environment and ergonomic issues in green buildings. Retrospective post-occupancy evaluation survey of 319 occupants in two Leadership in Energy and Environmental Design (LEED) certified buildings and one conventional building on a Canadian University campus. Results show that working in the LEED buildings was a generally positive experience for their health, performance, and satisfaction. However, the LEED buildings did not always receive the highest ratings for environmental conditions or for health and productivity. Respondents indicated a range of concerns with thermal conditions, office lighting, noise and their overall workstation designs and these were not always better in the green buildings. These results highlight the need for better integration of ergonomic design into green buildings and into the LEED rating system, and these implications are discussed.

Energy Technology Data Exchange (ETDEWEB)

Khanna, Nina; Romankiewicz, John; Feng, Wei; Zhou, Nan; Ye, Qing

2014-04-01

Prominent barriers facing the U.S. green building industry include the fact that government bodies that supervise health, fire safety, land, and other public operations are slow to revise codes to accommodate green building (regulatory barrier). In China, the lack of a green building professional accreditation process similar to the Leadership in Energy and Environmental Design (LEED) AP process limits the green building workforce capacity development (informational barrier). The main policies highlighted in this report to tackle these barriers are 1) comprehensive codes and labeling plan (informational, institutional), 2) government-led targets and demonstrations (risk), 3) education and awareness programs (informational), 4) fiscal policy that supports green building investment (financial), and 5) integrated design promotion (institutional, financial).

Green building is an important component of sustainable real estate market development, and one of the reasons is that the construction industry consumes a high amount of resources. Energy consumption of construction industry results in greenhouse gas emissions, so green buildings, energy systems, building technologies and other aspects play an important role in sustainable development of real estate market, construction and environmental development. The aim of the research is to analyse environmental aspects of sustainable real estate market development, focusing on importance of green buildings at the industry level and related energy aspects. Literature review, historical, statistical data analysis and logical access methods have been used in the research. The conducted research resulted in high environmental rationale and importance of environment-friendly buildings, and there are many green building benefits during the building life cycle. Future research direction is environmental information process and its models.

Can green building councils serve as third party governance institutions? An economic and institutional analysis

International Nuclear Information System (INIS)

Sedlacek, Sabine; Maier, Gunther

2012-01-01

Green Building Councils (GBCs) have been established in many different countries in recent years. This paper discusses the role such organizations can play in the respective construction and real estate industry and under what circumstances a GBC can contribute positively to the development of a “greener” or “more sustainable” stock of buildings. The paper investigates the main informational problem of the industry by looking at the relation between a developer and an investor from an economic point of view. We argue that the investor's uncertainty about the true quality of a building and the corresponding incentive for the developer to cheat may lock them into a prisoners' dilemma trap. The corresponding barriers for a transition toward a “greener” buildings market are analyzed. GBCs are described as institutions of economic governance that can assist the economy in overcoming these problems. They can act as third party institutions in transactions between developers and investors. By certifying the quality of a building, they can reduce the risk for the investor to be cheated by the developer and also increase the incentive to develop good quality buildings for the developer. This task, however, raises some severe management challenges for the GBCs. - Highlights: ► We focus on Green Building Councils and their economic role. ► The paper investigates the informational problem of the sustainable building market. ► Developers and investors are locked in a prisoner's dilemma. ► Can the councils act as third party institutions to certify quality of buildings? ► Credibility and reliability are key features for third party certification.

Rastogi, Ankush; Choi, Jun-Ki; Hong, Taehoon; Lee, Minhyun

2017-01-01

Highlights: •Energy consumption change from applying different LEED versions were investigated. •Four analysis scenarios were compared using different versions of ASHRAE Standard. •A case study of a mid-rise multi-family building was conducted using energy simulation. •Residential buildings could benefit from LEED v4 due to the low prerequisite. •Renovation buildings are highly incentivized regardless of LEED version used. -- Abstract: Various versions of the Leadership in Energy and Environmental Design (LEED ® ) have been introduced with the addition of more stringent sustainability parameters and credit scoring schemes over the past decade. Such changes in LEED versions strongly affect the energy performance and LEED scores of the target building in the LEED certification process. Therefore, to validate and improve the current LEED version, it is crucial to investigate and compare the impact of different LEED versions on the building energy performance and scoring scheme. However, researches comparing the sustainability metrics for mid-rise multi-family buildings are rare. Therefore, this paper investigates the potential changes in the energy performance resulted from applying different LEED versions (i.e., LEED v3 and v4) for the Energy and Atmosphere (EA) category. Towards this end, a case study was carried out with energy modeling and simulation using TRACE 700 to compare the changes in the energy performance of four analysis scenarios applied to an existing mid-rise multi-family building located in Ohio. Results showed notable changes in LEED points when different versions of LEED using different ASHRAE Standards (i.e., ASHRAE Standards 90.1-2007 and 90.1-2010) are applied for the building energy analysis. In particular, mid-rise multi-family buildings could benefit from LEED v4 in terms of LEED credits as the prerequisite for the minimum energy performance improvement in EA category became significantly lenient compared to LEED v3.

Green buildings are designed to have low environmental impacts and improved occupant health and well-being. Improvements to the built environment including ventilation, lighting, and materials have resulted in improved indoor environmental quality (IEQ) in green buildings, but the evidence around occupant health is currently centered around environmental perceptions and self-reported health. To investigate the objective impact of green buildings on health, we tracked IEQ, self-reported health, and heart rate in 30 participants from green and conventional buildings for two weeks. 24 participants were then selected to be relocated to the Syracuse Center of Excellence, a LEED platinum building, for six workdays. While they were there, ventilation, CO 2 , and volatile organic compound (VOC) levels were changed on different days to match the IEQ of conventional, green, and green+ (green with increased ventilation) buildings. Participants reported improved air quality, odors, thermal comfort, ergonomics, noise and lighting and fewer health symptoms in green buildings prior to relocation. After relocation, participants consistently reported fewer symptoms during the green building conditions compared to the conventional one, yet symptom counts were more closely associated with environmental perceptions than with measured IEQ. On average, participants had 4.7 times the odds of reporting a lack of air movement, 1.4 more symptoms (p-value = 0.019) and a 2 bpm higher heart rate (p-value green and conventional buildings is driven by both environmental perceptions and physiological pathways.

Green power is generally defined as electricity produced from renewable sources, and whose production has low adverse impacts on the environment, human health and communities. Green power has near-zero greenhouse gas (GHG) emissions and includes sources such as wind, hydro, and solar power. Green power offers several environmental benefits, as well as the enhancement of energy security, regional development, economic diversification and the creation of skilled jobs. There are four categories of programs related to green power development in Canada: government green power policies, utility green power development programs, green power marketing initiatives, and green power certificate marketing initiatives. Most of the activities associated with these four categories in 2002 were discussed in this report. However, difficulties with quantification prevented the inclusion of some green power activities in the report, such as (1) the generation of green power not certified or identified by the generator as green power, (2) industry or residential self-generation, (3) net metering, and (4) small government programs. Each category was presented in detail. The information included in the report was based on surveys sent to each program proponent. Follow-up communications and other publicly available information was also included. New programs operating in 2003 or currently under development were listed. refs., 8 tabs

2008-12-15

This article discussed results of the 2008 Green Index survey conducted by Autodesk Inc., a company that is committed to developing software for easier and more efficient sustainable building design. The survey, which questioned members of the American Institute of Architects (AIA), revealed that architects and building owners have increased the implementation of sustainable design practices in response to a greater demand from clients. An increase in implementing green building elements of 15 per cent from 2007 may indicate a shift in attitude towards climate change. The primary reasons clients are asking for green buildings are reduced operating costs, marketing and marketing demand. The survey showed that 41 per cent of architects are using software to help predict and evaluate the environmental impact and lifecycle of their buildings as well as the HVAC operating costs and alternative building materials. The survey also showed that 24 per cent of architects are currently implementing green roofs on more than half of their new projects, compared with 7 per cent in 2007. Also, 39 per cent are using renewable, on-site energy sources such as solar, wind ,geothermal, low impact hydro, or biomass on more than half of new building designs compared with only 6 per cent in 2007. 1 ref.

The Priority Importance of Economic Motivation Factors Against Risks for Green Building Development in Malaysia

Directory of Open Access Journals (Sweden)

Mohamed Ghazali Farid Ezanee

2017-01-01

Full Text Available Green building development is an emerging paradigm for the construction industry practice all around the world. The establishement of Green Building rating tool helps to assess the whole life cycle process in planning to operation in a building. The Malaysian construction industry recognizes buildings that have been assessed using established green building tool such Green Building Index, Green RE or My CREST. Eventhough these rating tools provide motivation factors in its criteria and sub-criteria to promote sustainability in Malaysia buildings, there is still a major doubt to developers in terms of risks that may hinder their investments in green buildings. This paper highlights the priority importance of economic motivation factors against risks in the green building development in Malaysia. The data presented in this paper have been mainly derived from responses received through questionnaires completed by building stakeholders involved in green building developments. In order to determine the priority importance of economic motivation factors and risks identified for green building development, the questionnaire outcomes have been thoroughly assessed using the Analytical Hierarchy Process (AHP method. As a result, lack of government incentive and high capital cost, which classified under green building risks, are the two key factors with highest priority importance that influenced most of the decision making for green building development in Malaysia. The results show green buildings have proliferated as governmental support and incentives with more exampler of higher profit return of investment in enhancing developers preference for green building development.

The prediction of engineering cost for green buildings based on information entropy

Science.gov (United States)

Liang, Guoqiang; Huang, Jinglian

2018-03-01

Green building is the developing trend in the world building industry. Additionally, construction costs are an essential consideration in building constructions. Therefore, it is necessary to investigate the problems of cost prediction in green building. On the basis of analyzing the cost of green building, this paper proposes the forecasting method of actual cost in green building based on information entropy and provides the forecasting working procedure. Using the probability density obtained from statistical data, such as labor costs, material costs, machinery costs, administration costs, profits, risk costs a unit project quotation and etc., situations can be predicted which lead to cost variations between budgeted cost and actual cost in constructions, through estimating the information entropy of budgeted cost and actual cost. The research results of this article have a practical significance in cost control of green building. Additionally, the method proposed in this article can be generalized and applied to a variety of other aspects in building management.

Using the market at a cost: How the introduction of green certificates in Sweden lead to market inefficiencies

International Nuclear Information System (INIS)

Sundqvist, Thomas; Nilsson, Mats

2005-01-01

The paper examines the transactions costs in the Swedish electricity retail market arising as a result of the implementation of a green certificate system. Since transaction costs cannot be measured directly, we analyze the margin between what the retailers pay for the certificates and what they charge the end-users for the certificate service. Our results show the necessity to put either market or regulatory pressure on the retailers. There are strong indications that the retailers have used the green certificate market to extract oligopoly rents. We propose that the competitive pressure on the retailers should be strengthened by, for example, shifting the quota obligation to the retailers and/or by including the pricing of the certificate-service in the end-user price of electricity. Furthermore, we restate the obvious fact that the number of policy instruments implemented in a particular market matters insofar that each and every policy will create transaction costs. (Author)

Demystifying first-cost green building premiums in healthcare.

Science.gov (United States)

Houghton, Adele; Vittori, Gail; Guenther, Robin

2009-01-01

This study assesses the extent of "first-cost green building construction premiums" in the healthcare sector based on data submitted by and interviews with 13 current LEED-certified and LEED-registered healthcare project teams, coupled with a literature survey of articles on the topics of actual and perceived first-cost premiums associated with green building strategies. This analysis covers both perceived and realized costs across a range of projects in this sector, leading to the following conclusions: Construction first-cost premiums may be lower than is generally perceived, and they appear to be independent of both building size and level of "green" achievement; projects are using financial incentives and philanthropy to drive higher levels of achievement; premiums are decreasing over time; and projects are benefiting from improvements in health and productivity which, although difficult to monetize, are universally valued.

2002-02-01

The Green Building Challenge (GBC) in Canada was launched to help the building community meet environmental challenges and improve the environmental performance of buildings. Tools have been made available to the building industry to make informed environmental choices during the conception design stage of a project. The tools help architects, researchers and policy analysts in choosing material mixes and other design options that will minimize a building's potential life cycle environmental impacts and promote sustainable development. Green buildings involve the complete structure and envelope, including cladding, insulation, gypsum wall board, roofing and windows. The type of building and its location is also considered. Long term sustainability also considers energy use and emissions related to a building's energy system. This presentation described the following 3 projects which were selected for assessment in the GBC-2002: (1) the Mayo School in Mayo, Yukon Territory, (2) the Jackson-Triggs Winery in Niagara-on-the-Lake, Ontario, and (3) the Red River College in Winnipeg, Manitoba. The GBC-2002 Canadian Team nominated them as the best buildings being designed in Canada.10 figs.

All of our certification programs are the result of extensive industry research and program development and oversight by certification boards. For this project award, AEE proposed to work with the Department of Energy to utilize and extend existing industry recognized Certified Energy Auditor (CEA) and Certified Building Commissioning Professional (CBCP) programs under this Training Program Development Announcement. These expanded training programs will have significant impact in training professionals for building commissioning and energy auditing to achieve the goal of bringing existing buildings up to their optimal energy performance potential and ensuring that new buildings maintain their expected optimal level of performance. The goals and objectives of the training development project were achieved with the development of new training programs that are now being offered as self-sustaining commercial training and certification programs. These new programs are training and certifying professionals who are accomplishing the goal of increasing building energy performance in both existing and new buildings.

A green certificate market combined with a liberalised power market

International Nuclear Information System (INIS)

Morthorst, P.E.

2003-01-01

The development of renewable energy sources is expected to play an important role in the implementation of greenhouse gas (GHG) reduction targets in the EU member states. Among the highly relevant instruments for promoting the renewable development is the establishment of a market for tradable green certificates (TGCs) and markets based on TGCs or equivalent instruments are already established a number of places, among these Australia, Holland, England, Italy and Texas. Other countries are in the preparation phase. Sweden and Belgium (Flanders) are moving fast towards certificate-schemes, while although an early mover the Danish Parliament has postponed the introduction in Denmark until 2004-2005. The initiatives for establishing national TGC-markets are very much in line with the fixed targets for renewable development launched by the EU-commission. Thus, although the different countries have not chosen the same concept for establishing national TGC-markets, nevertheless there seems to be a good starting point for establishing an international one. This paper discusses the separate introduction of an international tradable green certificate market into a liberalised power market, especially in relation to cost-effectiveness and the possible contributions to national GHG-reduction strategies. The combination of a TGC and a liberalised power market encounters a number of problems in relation to achieving national GHG-reduction targets. One of the main results from a three-country case study described in the paper is that those countries most ambitious in renewable target setting by increasing their TGC-quotas will only partly be gaining the CO 2 -reduction benefits themselves. How large a share they gain themselves will depend only on the marginal conditions at the spot market

2013-09-01

Full Text Available Nowadays the growth of the cities increased built and paved areas, energy use and heat generation. The phenomenon of urban warming, called urban heat island, influences negatively outdoor comfort conditions, pollutants concentration, energy demand for air conditioning, as well as increases environmental impact due to the demand of energy generation. A sustainable technology for improving the energy efficiency of buildings is the use of green roofs and walls in order to reduce the energy consumption for conditioning in summer and improve the thermal insulation in winter. The use of green roofs and walls can contribute to mitigate the phenomenon of heat island, the emissions of greenhouse gases, and the storm water runoff affecting human thermal comfort, air quality and energy use of the buildings. Recently, a number of municipalities started to adopt regulations and constructive benefits for renovated and new buildings which incorporate green roofs and walls. The aim of this paper is to describe the green roofs and walls plant technology.

Building Envelope Thermal Performance Assessment Using Visual Programming and BIM, based on ETTV requirement of Green Mark and GreenRE

Full Text Available Accomplishment of green building design requirements and the achievement of the targeted credit points under a specific green rating system are known to be a task that is very challenging. Building Information Modeling (BIM design process and tools have already made considerable advancements in green building design and performance analysis. However, Green building design process is still lack of tools and workflows that can provide real-time feedback of building sustainability and rating during the design stage. In this paper, a new workflow of green building design assessment and rating is proposed based on the integration of Visual Programing Language (VPL and BIM. Thus, the aim of this study is to develop a BIM-VPL based tool for building envelope design and assessment support. The focus performance metric in this research is building Envelope Thermal Transfer Value (ETTV which is an Energy Efficiency (EE prerequisite requirement (up to 15 credits in both Green Mark and GreenRE rating systems. The development of the tool begins first by creating a generic integration framework between BIM-VPL functionalities and ETTV requirements. Then, data is extracted from the BIM 3D model and managed using Revit, Excel and Dynamo for visual scripting. A sample project consisting of a hypothetical residential building is run and its envelope ETTV performance and rating score are obtained for the validation of the tool. This tool will support project team in building envelope design and assessment by allowing them to select the most appropriate façade configuration according to its performance efficiency and the green rating. Furthermore, this tool serves as proof of concept that building sustainability rating and compliance checking can be automatically processed through customized workflows developed based on BIM and VPL technologies.

Swedish-Norwegian tradable green certificates: Scheme design flaws and perceived investment barriers

International Nuclear Information System (INIS)

Linnerud, Kristin; Simonsen, Morten

2017-01-01

The EU Commission recommends using market-based support schemes for renewable-electricity projects. One example is the Swedish-Norwegian tradable green certificate scheme. We examine whether design features in the Norwegian part of this scheme, specifically, the scheme's short duration and the way it is to be abruptly terminated, contribute to investors' perceptions of barriers. We apply econometric techniques on primary data collected in two surveys of Norwegian investors in hydropower, and we use real options theory to predict and interpret investors' responses. We show that: (1) immediately after the scheme was introduced, investors are eager to lock in future subsidies by investing immediately and concerned with factors that may delay the completion of their projects; (2) as the certificate deadline neared, investors have become increasingly pessimistic and concerned with economic and risk barriers. Investors in big hydropower plants with regulation reservoirs are particularly concerned with the risk of not completing their projects in time to gain the right to sell certificates. These findings are consistent with the predicted responses to the scheme design derived from real options theory. In contrast to earlier studies, we find no difference in responses to the scheme design across investor types. - Highlights: • The Swedish-Norwegian tradable green certificate scheme is intended to promote cost-efficiency. • We examine the optimism about and barriers against investing in new hydropower projects in Norway. • We find that scheme design may have contributed to barriers against Norwegian hydropower projects. • Thus, scheme design flaws may have prevented the scheme from working as intended. • These findings are consistent with real options theory predictions.

This article described a full-scale green renovation project undertaken by a construction management firm in Newton, Massachusetts. Chapman Construction and Design began renovating its own office building in late 2007 and completed it in September 2008. The firm set out to achieve LEED Platinum certification from the United States Green Building Council. The project involved energy saving modifications to its mechanical systems; replacing plumbing fixtures with high efficiency alternatives to reduce water consumption by at least 40 per cent; installing skylights and additional windows to allow more natural light into the interior space; salvaging doors, lighting, metal studs and masonry whenever possible; and using sustainable products such as recyclable carpets, tiles and low-VOC paint. The main feature of the renovation was a new 47 kW (DC) photovoltaic (PV) solar power array installed on the rooftop. The PV array includes 208 panels and a SunPower SPR-225 system that produces 55,000 kWh of clean power per year. This grid connected system will supply 90 per cent of the company's electricity needs. During times of peak production, excess power will be sent back to the utility. This article also described the 3 different roofing systems upon which the PV system was installed. All of the roofing systems were manufactured by the Firestone Building Products Company and included an innovative and highly reflective white thermoplastic polyolefin (TPO) single-ply roofing system; a RubberGard EPDM roofing system that was coated with Firestone's white AcryliTop coating which exceeds Energy Star requirements for energy efficiency; and a 1.5 mm Firestone UltraPly TPO membrane. The easy to install roofing systems were designed to prolong the service life of the roof and reflect solar radiation. 1 ref., 2 figs.

GREEN MANAGEMENT: THE REALITY OF BEING GREEN IN BUSINESS

ANALYTIC HIERARCHY PROCESS: AN APPLICATION IN GREEN BUILDING MARKET RESEARCH

Directory of Open Access Journals (Sweden)

Sharmin Attaran

2013-01-01

Full Text Available Sustainability has become a necessity in the building industry. In recent years, as the general public is more informed and aware of sustainability related issues, they are becoming major players in the decision making process regarding their built environment. However, there are still challenges with how sustainability is communicated to occupants and owners of buildings. As the global economic crisis is continuing, the marketing of green buildings needs to be refined to communicate the lifetime benefits of sustainability. One of the ways to develop effective marketing strategies, is to understand what the occupants value the most among many aspects of green buildings thus develop focused marketing solutions. Authors present a conceptual methodology using Analytic Hierarchy Process toward identifying consumer ranking and weights of a major green building rating system’s categories. Authors use sample non-representative data to illustrate the proposed methodology, while sharing preliminary qualitative data from the research in progress.

Study on the factors that influence the intention of college students to participate in the green building

Directory of Open Access Journals (Sweden)

Full Text Available The concept of green building has been extended for a period of time on both sides of the Taiwan Strait. However, there still is curiosity and skepticism in Fujian on green building. While in Taiwan, villages are filled with green-evolved houses and modern environmental farmhouses. With Theory of Planned Behavior as the framework, this study investigates influences of college students’ attitude toward green building, subjective norms of green building and perceived behavioral control of green building on the intention to participate in the green building. Findings show that college students’ attitude toward green building and the perceived behavioral control of green building significantly influence the intention to participate in the green building, but “subjective norms of green building” doesn’t have significant influence. The reason is probably that college students are at the rebellious stage and have high self consciousness and independent viewpoints.

2015-06-01

Green building materials are becoming more popular. However, little is known about their ability to support or limit microbial growth. The growth of fungi was evaluated on five building materials. Two green, two conventional building materials and wood as a positive control were selected. The materials were inoculated with Aspergillus versicolor, Cladosporium cladosporioides and Penicillium brevicompactum, in the absence and presence of house dust. Microbial growth was assessed at four different time points by cultivation and determining fungal biomass using the N-acetylhexosaminidase (NAHA) enzyme assay. No clear differences were seen between green and conventional building materials in their susceptibility to support microbial growth. The presence of dust, an external source of nutrients, promoted growth of all the fungal species similarly on green and conventional materials. The results also showed a correlation coefficient ranging from 0.81 to 0.88 between NAHA activity and culturable counts. The results suggest that the growth of microbes on a material surface depends on the availability of organic matter rather than the classification of the material as green or conventional. NAHA activity and culturability correlated well indicating that the two methods used in the experiments gave similar trends for the growth of fungi on material surfaces. © 2014 John Wiley & Sons A/S.

The impact of a 'green' building on employees' physical and psychological wellbeing.

Science.gov (United States)

Thatcher, Andrew; Milner, Karen

2012-01-01

Multiple claims and some empirical findings suggest that 'green' buildings should be healthier (psychologically and physically) and promote greater productivity than conventional buildings. The empirical evidence in this regard over the last decade or so has been inconclusive suggesting either that the studies are flawed or that there are specific aspects of green buildings that promote wellbeing and productivity and others that do not. This study looks at a longitudinal comparison of two groups; a group that moved into South Africa's first GreenStar-accredited building and a group that did not. Measures were taken before the move and six months later. Results demonstrated that the 'green' building did not produce significantly better physical or psychological wellbeing, or higher perceived productivity. These results are discussed in relation to suggestions for what design features to focus on that may produce significant results.

2018-04-01

Full Text Available Against the background of sustainable development, green building practices could be part of the strategy for solving environmental and energy problems in developing countries. The aim of this paper is to explore a system for the assessment of green buildings in China that provides the government and stakeholders with ways to improve their strategies for green building development. We apply a hybrid model, developed by integrating the Decision-Making Trial and Evaluation Laboratory and Analytical Network Process (called DANP method, to build an influential network relationship map (INRM between assessment systems and to derive the criterion weights. The INRM and derived weights can help us to understand this complex assessment system and to set improvement priorities for green building development. The results demonstrate that indoor environment, materials, and smart facilities are the top three critical factors for green building evaluation. Finally, we discuss some management implications based on an actual case study with solutions provided using this model.

Sudden decline in financial markets and economic meltdown has slow down adaptation and lowered interest of investors towards green certified buildings due to their higher initial costs. Similarly, it is essential to fetch investor’s attention towards more development of green buildings through automated tools for the construction projects. Though, historical dearth is found on the automation of green building rating tools that brings up an essential gap to develop an automated analog computerized programming tool. This paper present a proposed research aim to develop an integrated web-based automated analog computerized programming that applies green building rating assessment tool, green technology and life cycle cost analysis. It also emphasizes to identify variables of MyCrest and LCC to be integrated and developed in a framework then transformed into automated analog computerized programming. A mix methodology of qualitative and quantitative survey and its development portray the planned to carry MyCrest-LCC integration to an automated level. In this study, the preliminary literature review enriches better understanding of Green Building Rating Tools (GBRT) integration to LCC. The outcome of this research is a pave way for future researchers to integrate other efficient tool and parameters that contributes towards green buildings and future agendas.

Assessing and Developing the Application of LEED Green Building Rating System as a Sustainable Project Management and Market Tool in the Italian Context

2016-07-01

Full Text Available The paper discusses the recent introduction of the LEED system to the Italian context in order to assess its role to promote sustainable building process in the Italian context, pointing out its potentials on one hand as well as their gaps and limitations on the other hand, and suggests means for its future development. The study discusses the application of LEED as a ‘Sustainable Project management tool’ to guide sustainable building performance. This requires investigating the following: its structure, tools, assessment criteria along with its benchmarks and references. It also discusses the application of LEED as a ‘Sustainable building Certification and market tool’. This investigates the role and value of the LEED certification in the Italian Green market. The research method is comprised of three parts. The first part is a comparative analysis of LEED categories against Italian national initiatives for sustainability. The comparison showed that most LEED categories are already mandated by national norms and directives but they may differ in their stringency creating some areas of precedence of LEED system or drawbacks. This streamlines the adaptation process of LEED system to the Italian context. The second part investigates LEED projects’ market analysis. The result showed that the shift towards a sustainable building process is occurring slowly and on a vertical scale focusing on some building sectors rather than others. Its market diffusion in the Italian context faces challenges regarding the insufficient availability of green materials and products satisfying its requirements, as well as high soft cost of sustainability tests and expertise required. The Third part presents a practical review-citing the methodology and results of a survey conducted by the researchers in mid-2012. It is composed of a web-based questionnaire and interviews among a sample of LEED professionals in Italy. The result shows that LEED systems needs

An original tool for checking energy performance and certification of buildings by means of Artificial Neural Networks

Buratti, C.; Barbanera, M.; Palladino, D.

2014-01-01

Highlights: • ANN used as a tool for evaluating energy performance of buildings. • Training, validation, and testing of Neural Network with real energy certificates data. • Global energy performance index was chosen as a target of ANN. • A good correlation and a minimum error was found with certificates data. • A new energy index was defined in order to check the energy certificates. - Abstract: The Energy Performance Buildings Directive (EPBD) was issued to provide a common strategy for all European countries and to implement several actions for improving energy efficiency of buildings, responsible for 40% of energy consumption. Energy Performance Certificates are provided as a tool to evaluate the energy performance of buildings; however, costly and time-consuming controls are necessary to verify the accuracy of the set and declared data. Useful tools could be the Artificial Neural Networks (ANN), whereby it is possible to estimate the energy consumptions from specific parameters, to evaluate the accuracy of data in the energy certificates, and to identify the certificates needing accurate control. In this study, an Artificial Neural Network was developed based on approximately 6500 energy certificates (2700 are self-declaration) received by the Umbria Region (central Italy), in order to evaluate the global energy consumption of buildings from several and specific parameters reported in certificates. Data was checked in compliance with energy standards and only the correct certificates were used to train the Neural Network. The implemented Neural Network was tested with database data and a good correlation was found; in particular the energy performance calculated with the Neural Network presents an error greater than 15 kW h/m 2 year with respect to the real value of global energy performance index in only 3.6% of cases. Finally, a Neural Energy Performance Index (N.E.P.I.) was defined, in order to verify the accuracy of the energy certificates; the

Wang, Li; Li, Chuanghong

2018-02-01

As a sustainable form of ecological structure, green building is widespread concerned and advocated in society increasingly nowadays. In the survey and design phase of preliminary project construction, carrying out the evaluation and selection of green building design scheme, which is in accordance with the scientific and reasonable evaluation index system, can improve the ecological benefits of green building projects largely and effectively. Based on the new Green Building Evaluation Standard which came into effect on January 1, 2015, the evaluation index system of green building design scheme is constructed taking into account the evaluation contents related to the green building design scheme. We organized experts who are experienced in construction scheme optimization to mark and determine the weight of each evaluation index through the AHP method. The correlation degree was calculated between each evaluation scheme and ideal scheme by using multilevel gray relational analysis model and then the optimal scheme was determined. The feasibility and practicability of the evaluation method are verified by introducing examples.

Building green supply chains in eco-industrial parks towards a green economy: Barriers and strategies.

Science.gov (United States)

Li, Jacqueline; Pan, Shu-Yuan; Kim, Hyunook; Linn, Jean H; Chiang, Pen-Chi

2015-10-01

As suggested by UNEP, the key to sustainable development is to create a "green economy" which should encapsulate all three sectors: the industry, the people, and the government. Therefore, there is an urgent need to develop and implement the green technologies into the existing facilities, especially in the developing countries. In this study, the role of green supply chains in eco-industrial parks (EIPs) towards a green economy was investigated. The strategies and effective evaluation procedures of the green economy were proposed by assessing the barriers from the perspective of institution, regulation, technology, and finance. In addition, three case studies from iron and steel-making, paper mill and pulping, and petrochemical industries were presented and illustrated for building the green supply chains. For example, in the case of Lin-Hai Industrial Park, a total of 15 efficient green supply chains using waste-to-resources technologies were established by 2012, resulting in an economic benefit of USD 100 million per year. It suggests that the green supply chains should be established to achieve both economic growth and environmental protection. With these successful experiences, building a green supply chain within industrial park should be extensively promoted to make traditional industries around the world being environmentally bearable, economic viable, and social equitable.

Changes in productivity, psychological wellbeing and physical wellbeing from working in a 'green' building.

Science.gov (United States)

Thatcher, Andrew; Milner, Karen

2014-01-01

Based on improvements in indoor environmental quality claims are that 'green' buildings are healthier and promote greater productivity than conventional buildings. However, the empirical evidence over the last decade has been inconclusive, usually with flawed study designs. This study explored whether a 'green' building leads to a healthier, more productive work environment. A one-year, longitudinal comparison of two groups of employees of a large commercial bank; a group that moved into a GreenStar-accredited building and a group that stayed in a conventional building, was conducted. Measures of psychological wellbeing, physical wellbeing, productivity, and perceptions of the physical environment were taken before the move, six months later, and one year later. Results indicate that the 'green' building group had significantly increased self-reported productivity and physical wellbeing. The perceptions of the physical work environment indicate that respondents in the 'green' building group experienced significant air quality improvements (specifically, reduced stale air, better ventilation, improved air movement, reduced humidity, and conditions that were not too drafty) but perceived the lighting conditions as dimmer. Despite positive findings 'green' building rating tools require amendment to focus on those qualities that actually lead to improved wellbeing and productivity.

We review the context of commercial building design and construction in China, and look at a specific project as an example of a high performance, sustainable design, the Shenzhen Institute of Building Research (IBR. The IBR building incorporates over 40 sustainable technologies and strategies, including daylighting, natural ventilation, gray-water recycling, solar-energy generation, and highly efficient Heating Ventilation and Air Conditioning (HVAC systems. We present measured data on the performance of the building, including detailed analysis by energy end use, water use, and occupant comfort and satisfaction. Total building energy consumption in 2011 was 1151 MWh, with an Energy Use Intensity (EUI of 63 kWh/m2 (20 kBtu/ft2, which is 61% of the mean EUI value of 103 kWh/m2 (33 kBtu/ft2 for similar buildings in the region. We also comment on the unique design process, which incorporated passive strategies throughout the building, and has led to high occupant satisfaction with the natural ventilation, daylighting, and green patio work areas. Lastly we present thoughts on how the design philosophy of the IBR building can be a guide for low-energy design in different climate regions throughout China and elsewhere.

At present, we are constructing houses and buildings without giving any consideration to consumption of resources at the time of construction and consumption of resources for the use of such houses or buildings. ; Although green is our color but we are doing little about green building. Time has now come to propagate Green Building Construction Concepts in order to save our precious resources. The paper deals with dire need of awareness about conservation of water, conservation of energy, use of local materials, use of natural materials, etc. (author)

Green Template for Life Cycle Assessment of Buildings Based on Building Information Modeling: Focus on Embodied Environmental Impact

Directory of Open Access Journals (Sweden)

Sungwoo Lee

2015-12-01

Full Text Available The increased popularity of building information modeling (BIM for application in the construction of eco-friendly green buildings has given rise to techniques for evaluating green buildings constructed using BIM features. Existing BIM-based green building evaluation techniques mostly rely on externally provided evaluation tools, which pose problems associated with interoperability, including a lack of data compatibility and the amount of time required for format conversion. To overcome these problems, this study sets out to develop a template (the “green template” for evaluating the embodied environmental impact of using a BIM design tool as part of BIM-based building life-cycle assessment (LCA technology development. Firstly, the BIM level of detail (LOD was determined to evaluate the embodied environmental impact, and constructed a database of the impact factors of the embodied environmental impact of the major building materials, thereby adopting an LCA-based approach. The libraries of major building elements were developed by using the established databases and compiled evaluation table of the embodied environmental impact of the building materials. Finally, the green template was developed as an embodied environmental impact evaluation tool and a case study was performed to test its applicability. The results of the green template-based embodied environmental impact evaluation of a test building were validated against those of its actual quantity takeoff (2D takeoff, and its reliability was confirmed by an effective error rate of ≤5%. This study aims to develop a system for assessing the impact of the substances discharged from concrete production process on six environmental impact categories, i.e., global warming (GWP, acidification (AP, eutrophication (EP, abiotic depletion (ADP, ozone depletion (ODP, and photochemical oxidant creation (POCP, using the life a cycle assessment (LCA method. To achieve this, we proposed an LCA method

China is constructing new commercial buildings at an enormous rate -- roughly 2 billion square meters per year, with considerable interest and activity in green design and construction. We review the context of commercial building design and construction in China, and look at a specific project as an example of a high performance, sustainable design, the Shenzhen Institute of Building Research (IBR). The IBR building incorporates over 40 sustainable technologies and strategies, including daylighting, natural ventilation, gray-water recycling, solar-energy generation, and highly efficient Heating Ventilation and Air Conditioning (HVAC) systems. We present measured data on the performance of the building, including detailed analysis by energy end use, water use, and occupant comfort and satisfaction. Total building energy consumption in 2011 was 1151 MWh, with an Energy Use Intensity (EUI) of 63 kWh/m² (20 kBtu/ft²), which is 61% of the mean EUI value of 103 kWh/m² (33 kBtu/ft²) for similar buildings in the region. We also comment on the unique design process, which incorporated passive strategies throughout the building, and has led to high occupant satisfaction with the natural ventilation, daylighting, and green patio work areas. Lastly we present thoughts on how the design philosophy of the IBR building can be a guide for low-energy design in different climate regions throughout China and elsewhere.

Sustainable architecture is meant to preserve the environment and conserve natural resources, as well as provide an environment for the occupants that promotes wellbeing and productivity. Occupants generally claim that the acoustical environment is the least satisfactory aspect of green office buildings. They are dissatisfied with excessive noise and poor speech privacy. This paper reported on the results of 2 studies of the acoustical environments in green office buildings before and after acoustical-control measures were installed. Acoustical quality was evaluated by occupant-satisfaction surveys and acoustical-parameter measurements. The first study, which involved 6 green office buildings, showed that buildings designed to obtain LEED ratings are unlikely to have satisfactory acoustical environments. A naturally-ventilated, green university building with a poor acoustical environment was examined in the second study. The results of this study suggest that improving acoustical environments in green buildings requires good acoustical design, with input from an acoustical specialist from the beginning of the design process. The design should consider site selection and building orientation; external envelope and penetrations in it; building layout and internal partitions; HVAC systems; appropriate dimensioning of spaces; and the amount and location of sound absorbing treatments. The study also showed that a building's energy efficiency, lighting, ventilation, air-quality and acoustics are interconnected, and that no aspect can be successfully designed in isolation. It was concluded that optimized engineering-control measures can improve poor acoustical environments. 11 refs., 1 tab., 1 fig.

Is Halal Certification Process “Green”?

Directory of Open Access Journals (Sweden)

Mohd Rizal Razalli

2012-09-01

Full Text Available These days, the environmental perspective on operations is becoming more common. In fact, any effort in improving efficiency in the organization is closely related to sustainability of our environment. The Environmental Management System (EMS certification such as ISO 14001 has been accepted as the world standard. In addition to these ISO standards, there are other certifications such as Halal certification. There is no research that investigates the relationship between Halal Certification process and its effect on our environment. Hence, our main research question is that is Halal Certification process can be considered as environmental friendly? In this paper, we argue that Halal Certification also contributes towards green initiatives. We used EDC-UUM as our case study. EDC-UUM is actively seeking the Halal certification from Malaysian authority agency or JAKIM. In this study, we assessed the perception of the EDC-UUM staff on the issue of going green. The findings and implications are discussed in the paper. Keywords: halal certification, hotel operations, sustainability, green

Non-Destructive Current Sensing for Energy Efficiency Monitoring in Buildings with Environmental Certification.

Nowadays, buildings environmental certifications encourage the implementation of initiatives aiming to increase energy efficiency in buildings. In these certification systems, increased energy efficiency arising from such initiatives must be demonstrated. Thus, a challenge to be faced is how to check the increase in energy efficiency related to each of the employed initiatives without a considerable building retrofit. In this context, this work presents a non-destructive method for electric current sensing to assess implemented initiatives to increase energy efficiency in buildings with environmental certification. This method proposes the use of a sensor that can be installed directly in the low voltage electrical circuit conductors that are powering the initiative under evaluation, without the need for reforms that result in significant costs, repair, and maintenance. The proposed sensor consists of three elements: an air-core transformer current sensor, an amplifying/filtering stage, and a microprocessor. A prototype of the proposed sensor was developed and tests were performed to validate this sensor. Based on laboratory tests, it was possible to characterize the proposed current sensor with respect to the number of turns and cross-sectional area of the primary and secondary coils. Furthermore, using the Least Squares Method, it was possible to determine the efficiency of the air core transformer current sensor (the best efficiency found, considering different test conditions, was 2%), which leads to a linear output response.

Green buildings uses processes that are environmentally responsible and resource-efficient throughout a building's life-cycle. In these buildings Certain energy conservative and environment friendly steps are considered and implemented from design, construction, operation, maintenance and renovation. In present era no doubt new technologies are constantly constructed and used in creating greener structures, energy efficient buildings. The common objective is to reduce the overall impact of the built environment on human health using available energy efficiently. To increase the efficiency of the System or the building, Onsite generation of renewable energy through solar power, wind power, hydro power, or biomasscan significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building. Any how power generation using renewable sources that is Solar system may further enhance energy conservation ideas. Power Factor improvement can also be another source of efficient tool for efficient use of Electrical Energy in green buildings. In developing countries a significant amount of Electrical Energy can be conserved and System efficiency as a whole can be increased by Power Factor correction. The reverse flow of power can be locally engaged instead of creating extra stress and opposition to the existing grid lines.

Financial risks for green electricity investors and producers in a tradable green certificate market

International Nuclear Information System (INIS)

Lemming, Jacob

2003-01-01

This paper analyzes financial risks in a market for tradable green certificates (TGC) from two perspectives; existing renewable producers and potential investors in new renewable electricity generation capacity. The equilibrium pricing mechanism for a consumer-based TGC market is described and a market with wind turbines as the sole renewable technology is analyzed. In this framework, TGC prices and fluctuations in production from wind turbines will be negatively correlated and, as a result, TGC price fluctuations can actually help decrease the total financial risk. Based on this recognition, analytical expressions for revenue-variance-minimizing trading strategies are derived and an analysis of the demand and supply for financial hedging is used to show that forward contracts will be traded at a risk premium

Highlights: • Most of the Faculty Buildings studied are within the average of CO_2 emissions. • Academic and Research buildings have a similar simulated energy consumption. • Several restrictions found in the official Energy Performance Certification tool. • Average deviation of 30% between estimated and real energy consumption. • Electrical equipment and user behaviour notably increase the energy performance gap. - Abstract: A systematic method has been established to perform and analyse in detail the Energy Performance Certification of 21 Faculty Buildings located at the University of Zaragoza (Spain), according to the transposition of Directive 2010/31/EU. First of all, the problem background and a review of the state-of-the-art of the energy certification in buildings is outlined, regarding both the actual state of the Government regulations and the studies undertaken in several countries to assess the energy performance of different types of buildings, residential and non-residential. A summary of the causes found in other studies for the discrepancies between the estimated (by simulation) and actual energy consumption is shown which is afterwards tested and compared with the results found in the present study. Thereafter, the method followed to undertake the buildings’ Energy Performance Certification is explained, and the main results found together with the discussion are detailed, comparing actual vs. estimated energy consumption in the different case studies and proposing reasons for these deviations. The energy consumption breakdown by uses for several buildings is also analysed, and potential improvements for the simulation software are assessed.

Green signalling effects in the market for energy-efficient residential buildings

Fuerst, Franz; Oikarinen, Elias; Harjunen, Oskari

2016-01-01

Highlights: • Energy efficiency (EE) levels are hypothesised to affect house transaction prices. • We estimate a hedonic model using Energy Performance Certificates from Finland. • A price premium is found for the most energy-efficient properties. • The empirical results are suggestive of a green signalling effect. • Demand for EE high performers appears to be segmented from lower tiers. - Abstract: Empirical evidence from recent studies suggests that the price premium on energy-efficient buildings is potentially higher than the pure capitalisation of energy savings but the empirical evidence on the size of the non-savings components is scant. This study aims to fill this research gap by investigating whether the mandatory energy efficiency ratings for residential properties imply benefits that go beyond energy savings. Using a sample of several thousand apartment transactions from Helsinki, Finland, we first test if higher ratings were significantly associated with higher prices. In addition to a large number of property and neighbourhood characteristics, this dataset contains information on building-level energy usage which allows us to distinguish between the cost savings effect of energy consumption and the value of more intangible factors associated with the energy label. The hedonic model yields a statistically significant 3.3% price premium for apartments in the top three energy-efficiency categories and 1.5% when a set of detailed neighbourhood characteristics are included. When maintenance costs containing energy usage costs are added, a robust and significant price premium of 1.3% persists whereas no differentiation is found for the medium and lower rating categories. These findings may be indicative of energy-efficient buildings having signalling value – and therefore an additional incentive to invest in such buildings – for ‘green’ consumers. However, a favourable energy rating did not appear to speed up the sales process in the

The overall life cycle plays a significant role in the certification by German Sustainable Building Council (Stuttgart, Federal Republic of Germany). In order that certification becomes much more than only a documentation, comprehensive data are requested already in an early phase of planning. Early investigations of alternatives may have a significant influence on the life cycle of a building. But, from where do the auditors achieve these amounts of data without overcharging the partners involved in the planning process with questions. The Building Information Modelling contributes to the development of the future enhancement of process quality by an innovative information management.

Green buildings for Egypt: a call for an integrated policy

Bampou, P.

2017-11-01

As global warming is on the threshold of each country worldwide, Middle East and North African (MENA) region has already adopted energy efficiency (EE) policies on several consuming sectors. The present paper valuates the impact of temperature increase in the residential building sector of Egypt that is the most integrated example of the 7 out of the 20 MENA countries that have started their green efforts upon building environment. Furthermore, as it is based on a literature research upon socio-economic characteristics, existing building stock, existing legal and institutional framework, it elaborates a quantitative evaluation of Egypt's energy-saving potential, outlining basic constraints upon energy conservation, in order for Egypt to be able to handle the high energy needs due to its warm climate. Last but not least, the paper proposes a policy pathway for the implementation of green building codes and concludes with the best available technologies to promote EE in the Egyptian building sector.

Dynamic Simulation of the Green Roofs Impact on Building Energy Performance, Case Study of Antananarivo, Madagascar

Directory of Open Access Journals (Sweden)

Hery Tiana Rakotondramiarana

2015-05-01

Full Text Available Green roofs improve building energy performance and constitute an alternative to sustainable buildings. A green roof model is dynamically coupled with a building thermal model to assess its energy performance that takes into account the indoor air temperature dynamic changes. Under the climate conditions in Antananarivo, we compared green and conventional roofs. The present study shows that green roofs protect the roof structure under extreme temperature and large temperature fluctuations. For the case of Antananarivo, the amplitude of the temperature fluctuations at the top face of the support is reduced by 28 °C when using green roof. The impact of the green roof on indoor air temperature and energy demand is investigated. The vegetation decreases the maximum indoor air temperature and improves the building thermal comfort during summer days. It has no effect on the minimum indoor air temperature, but additional soil thickness can increase it. In addition, a global sensitivity analysis, which is carried out on the proposed model without considering any specific weather data, allows us to identify the most influential parameters on the energy demand. It has been found that green roofs have almost insignificant thermal impact in insulated buildings; however, their potential prevails over the building envelope and weather characteristics in the case of non-insulated building.

Green certificate markets, the risk of over-investment, and the role of long-term contracts

International Nuclear Information System (INIS)

Kildegaard, Arne

2008-01-01

Several papers have recently analyzed the theory and implementation of renewable energy support schemes. The case for a renewable electricity standard (RES) in tandem with a tradeable green certificate (TGC) market has been largely based on efficiency considerations. Case study evidence is inconclusive, in part due to the short track record, but is not generally favorable. Here we reconsider the efficiency case, both static and dynamic, in light of special characteristics of renewable energy projects. We find that when exclusively high fixed-cost technologies comprise the eligible technology pool, the equilibrium form of contracting obviates the principal efficiency advantages claimed for certificate markets. When low fixed-cost technologies compete alongside high fixed-cost technologies in the certificate market, we show that it is likely that long-term contracts will disappear, and the technological choice will be inefficiently shifted away from the high fixed-cost technology. We consider evidence from three well-developed certificate schemes - in Britain, Sweden, and Texas - and find that it is broadly consistent with the theory here. (author)

Theoretical Explanations of Environmental Motivations and Expectations of Clients on Green Building Demand and Investment

Joachim, Onuoha Iheanyichukwu; Kamarudin, Norhaya; Aliagha, Godwin Uche; Ufere, Kalu Joseph

2015-01-01

In building industry, green demand and investment creates a positive footprint on the environment. However, these environmental opportunities have not been adequately harnessed and explored by Clients of green building apparently because of poor understanding of the motivating drivers and benefits accruing from green building demand and investment. The decision to demand for or invest in green building is influenced by certain environmental motivating drivers and expectations which have not been fully examined by researchers and not well understood by stakeholders. Based on the Theory of Planned Behaviour (TPB) and Theory of Value Belief Norm (VBN) explanations, this study focused on the Clients, purchasers and users' motivations and intentions to go for green building. Based on the reviewed theories, we hypothesized that environmental motivations and expectations for green building demand and investment are embedded in the environmental quest for protection of eco-system and bio-diversity, improvement of water and air quality, reduction of solid waste, conservation of natural resources, reduction of societal costs of landfill creation and maintenance, minimization of site impact and reduction emission to air and enhanced energy efficiency. However, the predictive validity of these propositions depends on the client's beliefs, values, social pressure, and perceived behavioural control

Full Text Available Green roofs may be considered a passive energy saving technology that also offer benefits like environmental friendliness and enhancement of aesthetic and architectural qualities of buildings. This paper examines the energy and economic viability of the green roof technology in the hot humid climate of Saudi Arabia by considering a modern four bedroom residential building in the city of Dhahran as a case study. The base case and green roof modelling of the selected building has been developed with the help of DesignBuilder software. The base case model has been validated with the help of 3-month measured data about the energy consumption without a green roof installed. The result shows that the energy consumption for the base case is 169 kWh/m2 while the energy consumption due to the application of a green roof on the entire roof surface is 110 kWh/m2. For the three investigated green roof options, energy saving is found to be in the range of 24% to 35%. The economic evaluation based on the net present value (NPV approach for 40 years with consideration to other environmental advantages indicates that the benefits of the green roof technology are realized towards the end of the life cycle of the building.

Simulating price patterns for tradable green certificates to promote electricity generation from wind

International Nuclear Information System (INIS)

Ford, A.

2007-01-01

This article uses computer simulation to anticipate the price dynamics in a market for Tradable Green Certificates (TGCs). These markets have been used in Europe to promote generation of electricity from renewable resources like wind. Similar markets have been proposed in the United States of America (USA) where the certificates are called Renewable Energy Credits (RECs). The certificates are issued to the generating companies for each megawatt-hour of renewable electricity generation. The companies may sell the certificates in a market, and the revenues from certificate sales provide an extra incentive to invest in new generating capacity. Proponents argue that this market-based incentive can be designed to support government mandates for a growing fraction of electricity generation from renewable sources. In the USA, these mandates are set by the states and are known as Renewable Portfolio Standards (RPS). We simulate the price dynamics of a market designed to support an aggressive mandate for wind generation in the northwestern USA. The simulations show that the certificate price climbs rapidly to the cap in the early years after the market opens. Investors then react to these high prices with construction of new wind capacity. After a few years, wind generation meets, and then exceeds the requirement. We show that this pattern appears again and again when the simulations are repeated with wide variations in the estimates of behavioral parameters. We use the model to study the impact of different trading strategies by the wind companies and by the distribution companies. We also study the simulated market response if the USA adopts the carbon allowance market envisioned in The Climate Stewardship Act. The article concludes with recommendations for policy makers involved in TGC market design. [Author

These markets have been used in Europe to promote generation of electricity from renewable resources like wind. Similar markets have been proposed in the United States of America (USA) where the certificates are called Renewable Energy Credits (RECs). The certificates are issued to the generating companies for each megawatt-hour of renewable electricity generation. The companies may sell the certificates in a market, and the revenues from certificate sales provide an extra incentive to invest in new generating capacity. Proponents argue that this market-based incentive can be designed to support government mandates for a growing fraction of electricity generation from renewable sources. In the USA, these mandates are set by the states and are known as Renewable Portfolio Standards (RPS). We simulate the price dynamics of a market designed to support an aggressive mandate for wind generation in the northwestern USA. The simulations show that the certificate price climbs rapidly to the cap in the early years after the market opens. Investors then react to these high prices with construction of new wind capacity. After a few years, wind generation meets, and then exceeds the requirement. We show that this pattern appears again and again when the simulations are repeated with wide variations in the estimates of behavioral parameters. We use the model to study the impact of different trading strategies by the wind companies and by the distribution companies. We also study the simulated market response if the USA adopts the carbon allowance market envisioned in The Climate Stewardship Act. The article concludes with recommendations for policy makers involved in TGC market design

Using the market at a cost: How the introduction of green certificates in Sweden led to market inefficiencies

International Nuclear Information System (INIS)

Nilsson, Mats; Sundqvist, Thomas

2007-01-01

The paper examines the transactions costs in the Swedish electricity retail market arising as a result of the implementation of a green certificate system. Since transaction costs cannot be measured directly, we analyze the margin between what the retailers pay for the certificates and what they charge the end-users for the certificate service. Our results highlight some costs of implementing new policy and the necessity of a careful regulatory design. We propose that the price transparency should be strengthened by, for example, shifting the quota obligation to the retailers and/or by including the pricing of the certificate-service in the end-user price of electricity. Furthermore, we restate the obvious fact that the number of policy instruments implemented in a particular market matters insofar that each and every policy will create transaction costs. (author)

Standardization and Green Economic Change - the Case of Energy Efficiency in Buildings

DEFF Research Database (Denmark)

Andersen, Maj Munch; Faria, Lourenco

2015-01-01

This paper investigates the role of standardization for green economic change using energy efficiency in buildings as a case. Innovation research on standards tends to focus on the competition between competing emerging standards as well as the economic impacts of these. The idea pursued here...... energy efficiency becomes an issue in standardization work using buildings as a case. The paper seeks more specifically to investigate the rise of building related standards generally over time as well as in different technical areas and geographic regions. The hypothesis pursued in this paper...... is that the rise of the green economy can only take place accompanied by considerable institution formation in the form of standards. In this sense, the presence of standards may be seen as an important indicator on the maturity of the greening of the economy. The paper presents early empirical work...

Full Text Available At present, the green building and housing industrialization are two mainstream directions in the real estate industry. The production of green building parts which combines green building and housing industrialization, two concepts, is to be vigorously developed. The key of quality assurance in the assembly project is choosing reliable and proper green building parts suppliers. This paper analyzes the inherent requirements of the green building, combined with the characteristics of the housing industrialization, and puts forward an evaluation index system of supplier selection for green building parts, which includes product index, enterprise index, green development index, and cooperation ability index. To reduce the influence of subjective factors, the improved method which merges Kent index method and catastrophe theory is applied to the green building parts supplier selection and evaluation. This paper takes the selection of the unit bathroom suppliers as an example, uses the improved model to calculate and analyze the data of each supplier, and finally selects the optimal supplier. With combination of the Kent index and the catastrophe theory, the result shows that it can effectively reduce the subjectivity of the evaluation and provide a basis for the selection of the green building parts suppliers.

Scenarios for the use of GHG-reduction instruments - how can policy-instruments as carbon emission trading and tradable green certificates be used simultaneously to reach a common GHG-reduction target?

International Nuclear Information System (INIS)

Morthorst, P.E.

2000-01-01

According to the agreed burden sharing in the EU, a number of member states have to reduce their emissions of greenhouse gases substantially. To achieve these reductions various policy-instruments - national as well as international - are on hand. Two international instruments are emphasized in this paper: tradable quotas for limiting carbon emissions and tradable green certificates for promoting the deployment of renewable energy technologies. In the analyses of these two instruments two main questions are considered: (1) Will there be any international trade in green certificates, if no GHG-credits are attached to them? (2) Will it make any difference if the EU sets the targets to be achieved by the two instruments or alternatively the individual member countries do? An incentive-analysis in which four scenarios are set up and discussed is performed for the EU member states. The main conclusion is that if no GHG-credits are attached to the green certificates there seems to be limited of no incentives for a permanent international trade in certificates. On the other hand, if GHG-credits are attached to the certificates an efficient international trade will take place regardless of whether the EU or the member countries fix the quotas. Thus, the use of international instruments as tradable green certificates and tradable emissions permits will not lead to an optimal GHG-reduction strategy unless GHG-credits are attached to the certificates.

Design strategies for integration of green roofs in sustainable housing

Directory of Open Access Journals (Sweden)

Avi Friedman

2015-12-01

Full Text Available Green roofs are the integration of plant material and its supporting structures in buildings. Such an approach provides a habitat for local flora and fauna, helps manage storm water, reduces heat demand in winter and the cooling load in the summer, enhances the aesthetic values of dwellings, provides the occupants with comfort and amenities and strengthens environmental responsibility. Because roofs represent approximately 40 percent to 50 percent of the surfaces in urban areas, green roofs have an important role in drainage and as a result water management as well. In fact, when a green roof is installed on 50 percent or more of the roof’s surface, it guarantees 2 points and can contribute 7 additional points toward LEED certification - almost 20 percent of the required rating. This paper classifies green roofs and offers strategies for their integration in residential buildings and examines their benefits, construction principles and applications.

Based on the concept of sustainable development, green and ecology has become a hot topic in the development and research of many industries. It is not only a new culture, but also that art, technology, material and so on will change under the guidance of this kind of thought. Architecture is the main body of the city, and it also is the necessary component of the human survival and social developments, the basic function of the building is to provide people with living space. With the development of society, the architectural function is constantly enriched, the structure tends to be complicated, but the influence of its own problems is also expanding. The development of the construction industry requires a lot of resources, and in the process of using its function and it needs other energy to provide its due support, because in the past we only consider the building function, ignoring the energy and information consumption. Considering the current social development, we have to take the energy and resource issues into account, based on this condition, the green eco-building concept and technical standards is producing, and it changed people’s views on social development. Green eco-buildings also need to have indicators as a reference, while providing guidance of architectural design and construction. This paper gives a brief exposition of the research system of green ecological architecture and its evaluation.

Multiobjective optimization design of green building envelope material using a non-dominated sorting genetic algorithm

International Nuclear Information System (INIS)

Yang, Ming-Der; Lin, Min-Der; Lin, Yu-Hao; Tsai, Kang-Ting

2017-01-01

Highlights: • An effective envelope energy performance model (BEM) was developed. • We integrated NSGA-II with the BEM to optimize the green building envelope. • A tradeoff plan of green building design for three conflict objectives was obtained. • The optimal envelope design efficiently reduced the construction cost of green building. - Abstract: To realize the goal of environmental sustainability, improving energy efficiency in buildings is a major priority worldwide. However, the practical design of green building envelopes for energy conservation is a highly complex optimization problem, and architects must make multiobjective decisions. In practice, methods such as multicriteria analyses that entail capitalizing on possibly many (but in nearly any case limited) alternatives are commonly employed. This study investigated the feasibility of applying a multiobjective optimal model on building envelope design (MOPBEM), which involved integrating a building envelope energy performance model with a multiobjective optimizer. The MOPBEM was established to provide a reference for green designs. A nondominated sorting genetic algorithm-II (NSGA-II) was used to achieve a tradeoff design set between three conflicting objectives, namely minimizing the envelope construction cost (ENVCOST), minimizing the envelope energy performance (ENVLOAD), and maximizing the window opening rate (WOPR). A real office building case was designed using the MOPBEM to identify the potential strengths and weaknesses of the proposed MOPBEM. The results showed that a high ENVCOST was expended in simultaneously satisfying the low ENVLOAD and high WOPR. Various designs exhibited obvious cost reductions compared with the original architects' manual design, demonstrating the practicability of the MOPBEM.

Are green building features safe for preventive maintenance workers? Examining the evidence.

Omar, Mohamed Shamun; Quinn, Margaret M; Buchholz, Bryan; Geiser, Ken

2013-04-01

Many newly constructed green buildings (GB) are certified using the United States Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) rating system for new construction and major renovation which focuses on architectural and mechanical design to conserve energy, reduce environmental harm, and enhance indoor quality for occupants. This study evaluated the preventive maintenance (PM) worker occupational safety and health (OSH) risks related to the design of GB. PM job hazard analyses (JHA) were performed on the tasks required to operate and maintain five GB features selected from 13 LEED certified GB. A 22-item JHA and OSH risk scoring system were developed. Potentially serious OSH hazards included: green roofs made of slippery material without fall protection; energy recovery wheels and storm water harvesting systems in confined spaces; skylights without guard rails; and tight geothermal well mechanical rooms constraining safe preventive practices. GB can present PM OSH risks and these should be eliminated in the building design phase. Copyright © 2013 Wiley Periodicals, Inc.

Green Certificates and Market Power on the Nordic Power Market

International Nuclear Information System (INIS)

Bergman, Lars; Amundsen, Eirik S

2007-06-01

In Sweden a market for Tradable Green Certificates (TGCs) was introduced in 2003. The purpose was to stimulate investments in electricity generation based on renewable energy sources without using direct governmental subsidies to renewable energy. More precisely the aim is to create a market where different types of renewable electricity can compete on equal terms, thus relieving governments and public agencies from being directly involved in power industry investment decisions. The purpose of this study is to elucidate under which circumstances, how, and to what extent market power in the TGC market can be used to affect the entire electricity market. There are basically two reasons for being concerned with market power in TGC markets. The first is the fact that the industry average cost curve for 'green' electricity tends to be upward sloping. This is because the cost of wind power, the main source of green electricity, depends on the location of the power plants, and that the availability of first rate sites that do not involve sizable investments in new transmission and network infrastructure, is limited. The situation is similar for environmentally friendly hydro power, and, to some extent, for other types of 'green' electricity. Thus, given the state of technology and an upper cost limit, there is a maximum amount of 'green' electricity that can be produced within a country. This means that some generators, by getting access to the suitable sites, will become dominating producers of 'green' electricity and thus may be able to exercise market power in the TGC market. The second reason for being concerned with market power in a TGC market is that, as a result of the percentage requirement, the withdrawal of a given number of TGCs from the market forces a much larger reduction of electricity consumption. Thus relatively modest exercise of market power in the TGC market may have a significant impact on the price of electricity and the allocation of resources in

The volume of electricity sold to consumers in the voluntary green electricity market is growing continuously. On 1 January 2013 the Certificates of Origin Registry of the German Federal Environmental Office went into service. This authority obliges electricity suppliers in Germany to use its services if they wish to prove to their final customers that they are supplying them with electricity from ''other renewable resources''. This gives rise to the question as to how certificates of origin can contribute to the further development and to meaningful differentiation in the green electricity market.

There are limited data on air quality parameters, including airborne particulate matter (PM) in residential green buildings, which are increasing in prevalence. Exposure to PM is associated with cardiovascular and pulmonary diseases, and since Americans spend almost 90% of their time indoors, residential exposures may substantially contribute to overall airborne PM exposure. Our objectives were to: (1) measure various PM fractions longitudinally in apartments in multi-family green buildings with natural (Building E) and mechanical (Building L) ventilation; (2) compare indoor and outdoor PM mass concentrations and their ratios (I/O) in these buildings, taking into account the effects of occupant behavior; and (3) evaluate the effect of green building designs and operations on indoor PM. We evaluated effects of ventilation, occupant behaviors, and overall building design on PM mass concentrations and I/O. Median PMTOTAL was higher in Building E (56 µg/m³) than in Building L (37 µg/m³); I/O was higher in Building E (1.3-2.0) than in Building L (0.5-0.8) for all particle size fractions. Our data show that the building design and occupant behaviors that either produce or dilute indoor PM (e.g., ventilation systems, combustion sources, and window operation) are important factors affecting residents' exposure to PM in residential green buildings.

Strategies for Promoting Green Building Technologies Adoption in the Construction Industry—An International Study

Directory of Open Access Journals (Sweden)

Albert Ping Chuen Chan

2017-06-01

Full Text Available Because green building technologies (GBTs adoption is a promising way of ameliorating the sustainability performance of buildings, GBTs are receiving increased interest in the global construction community. The barriers to the adoption of GBTs, such as higher cost and lack of awareness, further indicate that proper strategies need to be devised for promoting the wider adoption of GBTs in buildings development. However, there exist limited empirical studies identifying the strategies for promoting GBTs adoption in the construction industry. This study aims to identify the strategies that are important for promoting GBTs adoption in construction. After a comprehensive literature review to identify strategies for the promotion of GBTs adoption, empirical data were gleaned through a questionnaire survey with 104 green building experts around the world. The analysis results validated the importance of all of the 12 promotion strategies used for the study. Green building experts from different countries and with different backgrounds had significant agreement on the relative importance ranking of the promotion strategies. Furthermore, “financial and further market-based incentives for GBTs adopters”, “availability of better information on cost and benefits of GBTs”, “mandatory governmental policies and regulations”, and “green rating and labeling” were identified as the top four important promotion strategies. The research findings provide a valuable reference to assist practitioners and policy makers in developing practical strategies for promoting GBTs adoption to eventually achieve the sustainable development of buildings. From the perspective of international experts, this study adds to the green building literature by offering empirical evidence of the important strategies for promoting GBTs adoption in the construction industry. Future research will investigate the interrelationships among the promotion strategies and their

The implementation of Green Building criteria is relatively new in architectural practice, especially in Indonesia. Consequently, the integration of these criteria into design process has the potential to change the design process itself. The implementation of the green building criteria into the conventional design process will be discussed in this paper. The concept of this project is to design a residential unit with a natural air-conditioning system. To achieve this purpose, the Green Building criteria has been implemented since the beginning of the design process until the detailing process on the end of the project. Several studies was performed throughout the design process, such as: (1) Conceptual review, where several professionally proved theories related to Tropical Architecture and passive design are used for a reference, and (2) Computer simulations, such as Computational Fluid Dynamics (CFD) and wind tunnel simulation, used to represent the dynamic response of the surrounding environment towards the building. Hopefully this paper may become a reference for designing a green residential building.

2013-03-31

Universidad del Turabo (UT), in a collaborative effort with Global Turn Key Services, Inc. (GTKS), proposed to develop a training program and a commercialization plan for the development of Commercial Building Operators (CBOs). The CBOs will operate energy efficient buildings to help maintain existing buildings up to their optimal energy performance level, and ensure that net-zero-energy buildings continuously operate at design specifications, thus helping achieve progress towards meeting BTP Strategic Goals of creating technologies and design approaches that enable net-zero-energy buildings at low incremental costs by 2025. The proposed objectives were then: (1) Develop a Commercial Building Operator (CBO) training program and accreditation that will in turn provide a certification to participants recognized by Accreditation Boards such as the North American Board of Certified Energy Practitioners (NABCEP) and Leadership in Energy & Environmental Designs (LEED). (2) Develop and implement a commercialization and sustainability plan that details marketing, deployment, financial characterization, job placement, and other goals required for long-term sustainability of the project after the funding period. (3) After program development and deployment, provide potential candidates with the knowledge and skill sets to obtain employment in the commercial building green energy (net-zero-energy building) job market. The developed CBO training program will focus on providing skills for participants, such as displaced and unemployed workers, to enter the commercial building green energy (net-zeroenergy building) job market. This course was designed to allow a participant with minimal to no experience in commercial building green technology to obtain the required skill sets to enter the job market in as little as 12 weeks of intensive multi-faceted learning. After completion of the course, the CBO staff concluded the participant will meet minimum established accreditation

The awareness of health issues related to buildings has heightened past decades. Indoor Environmental Quality (IEQ) has been addressed in most Green Building Rating Systems nowadays. This article analyses the scope of IEQ (Indoor Environmental Quality) within Rating Systems GPR Gebouw, BREEAM-NL (Dutch version of Building Research Establishment's Environmental Assessment Method) and LEED (Leadership in Energy and Environmental Design). Each Rating System allocates health aspects. However, none of these Rating Systems addresses a complete set of relevant aspects. High ratings do not guarantee healthy buildings. It is concluded that, in general, credits for energy efficiency do not interfere with credits for enhanced indoor environmental quality. [Dutch] Gezondheidsaspecten van gebouwen hebben afgelopen decennia steeds meer en integraler aandacht gekregen. In de instrumenten GPR Gebouw, BREEAM-NL (Nederlandse versien van 'Building Research Establishment's Environmental Assessment Method') en LEED (Leadership in Energy and Environmental Design) is gezondheid 1 van de duurzaamheidsthema's, in dit artikel wordt geconcludeerd dat deze instrumenten veel gezondheidsaspecten dekken maar dat geen enkel instrument echt volledig is. De 1 legt meer accent op gezondheid, de ander meer op comfort. Een hoog label biedt geen garantie voor een gezond gebouw. De instrumenten bevatten weinig potentieel strijdige aspecten. Gezond en energiezuinig bouwen gaan volgens deze instrumenten goed samen.

Renewable energy sources that are commonly used in buildings include solar energy, wind energy and rainwater collection. High quality environmentally responsive residential buildings are designed to provide good insulation in winter and solar shading in summer. However, this study demonstrated that the green energy design in residential buildings is not usually well integrated. For example, windows with clear double or triple glazed glass, allow good penetration of sunlight during the day in winter, but are not further dynamically insulated for when the sun goes down to avoid heat loss from the building. Additionally, good solar static shading devices often block much needed daylight on cloudy winter days. These examples emphasize the lack of an integrated approach to gain the best advantage of green energies and to minimize energy costs in residential buildings. This study addressed issues facing the integrated approach with particular reference to the design of a small residential building in rural Beijing. The design included a new approach for interpreting a traditional Beijing court yard house in the modern Beijing rural context, while integrating multi-responding innovative green energy applications derived from first principles. This paper also presented a proposal for a village house in Hong Kong to harvest as much renewable energies as possible, primarily wind energy and solar energy, that come into contact with the building. The purpose was to work towards a renewable energy approach for buildings, namely the Bireth approach, which will benefit practically all houses by making them zero energy houses. The paper described the feasibility of integrating renewable energies in buildings to fulfill performance requirements such improving ventilation, providing warm interiors, drying clothes, or storing solar and wind energies into power batteries. The challenges facing the development of a proposed micro solar hot air turbine were also presented. 15 refs., 6

A mini review on the integration of resource recovery from wastewater into sustainability of the green building through phycoremediation

Green building implementation is an important assessment for sustainable development to establish a good quality of the environment. To develop the future green building implementation, resource recovery from the building wastewater is significantly important to consider as a part of the green building development. Discharge of urban wastewater into water bodies trigger of eutrophication in the water catchment, accordingly need further treatment to recover the nutrient before it is reused or discharged into receiving water bodies. In this regard, integration of microalgae cultivation in closed photobioreactor as building façade is critically important to be considered in the implementation of the green building. Microalgae offer multi-function as bioremediation (phycoremediation) of the wastewater, production of the biofuels, and important algal bio-products. At the same time, algae façade boost the reduction of the operating cost in forms of light, thermal energy and add the benefit into the building for energy reduction and architecture function. It promises an environmental benefit to support green building spirit through nutrient recovery and wastewater reuse for algae cultivation and to enhance the aesthetic of the building façade.

Highlights: • This study evaluates the building energy efficiency rating (BEER) certification. • Prediction model was developed for cost saving potentials by the BEER certification. • Prediction model was developed using LCC analysis, ROV, and Monte Carlo simulation. • Cost saving potential was predicted to be 2.78–3.77% of the construction cost. • Cost saving potential can be used for estimating the investment value of BEER. - Abstract: Building energy efficiency rating (BEER) certification is an energy performance certificates (EPCs) in South Korea. It is critical to examine the cost saving potentials of the BEER-certification in advance. This study aimed to develop a prediction model for the cost saving potentials in implementing the BEER-certification, in which the cost saving potentials included the energy cost savings of the BEER-certification and the relevant CO_2 emissions reduction as well as the additional construction cost for the BEER-certification. The prediction model was developed by using data mining, life cycle cost analysis, real option valuation, and Monte Carlo simulation. The database were established with 437 multi-family housing complexes (MFHCs), including 116 BEER-certified MFHCs and 321 non-certified MFHCs. The case study was conducted to validate the developed prediction model using 321 non-certified MFHCs, which considered 20-year life cycle. As a result, compared to the additional construction cost, the average cost saving potentials of the 1st-BEER-certified MFHCs in Groups 1, 2, and 3 were predicted to be 3.77%, 2.78%, and 2.87%, respectively. The cost saving potentials can be used as a guideline for the additional construction cost of the BEER-certification in the early design phase.

Building has a big impact on the environmental developments. There are three general motives in building, namely the economy, society, and environment. Total completed building construction in Indonesia increased by 116% during 2009 to 2011. It made the energy consumption increased by 11% within the last three years. In fact, 70% of energy consumption is used for electricity needs on commercial buildings which leads to an increase of greenhouse gas emissions by 25%. Green Building cycle costs is known as highly building upfront cost in Indonesia. The purpose of optimization in this research improves building performance with some of green concept alternatives. Research methodology is mixed method of qualitative and quantitative approaches through questionnaire surveys and case study. Assessing the successful of optimization functions in the existing green building is based on the operational and maintenance phase with the Life Cycle Assessment Method. Choosing optimization results were based on the largest efficiency of building life cycle and the most effective cost to refund.

Exploring Socio-Technical Features of Green Interior Design of Residential Buildings: Indicators, Interdependence and Embeddedness

Directory of Open Access Journals (Sweden)

Yan Ning

2016-12-01

Full Text Available This research aims to develop indicators for assessing green interior design of new residential buildings in China, grounded in the socio-technical systems approach. The research was carried out through a critical literature review and two focus group studies. The results show that the boundaries of green interior design were identified with respect to three dimensions, namely performance, methodology and stakeholders. The socio-technical systems approach argues for the recognition of the interdependence between the systems elements and the feature of embeddedness. The interdependence of the systems elements exists within each of these three dimensions and across them. It is also found that the socio-technical systems of green interior design are embedded in the social, regulatory and geographic context. Taking interior design of residential buildings as the empirical setting, this study contributes to the literature of green building assessment by presenting a socio-technical systems approach.

To address the worsening problems of global warming and the urban heat island effect, ecological cities and building environment greening are being promoted in population-dense urban areas domestically and abroad. For example, the Japanese Ministry of Land, Infrastructure, Transport, and Tourism announced the CASBEE-HI (Heat Island) assessment system in 2008 as a response to worsening urban warming and urban heat island effects. The Ministry implemented ''Building Space Greening Plans'' in Tokyo, Osaka, and other cities, enforcing by law the effective reduction of urban temperatures and improving urban living environments and alleviating the threat of urban ecological disasters. Therefore, this study integrates Taiwan domestic and foreign building space greening design, derived greening benefits, implementation promotion methods, and greening design policies as measurement constructs to examine the mutual influence between different constructs and to analyze the degree of influence on the urban real estate market. From the result, demonstrating that building space environment greening design does bring about positive benefits. In addition, the greening benefit was shown to have a positive impact on the urban real estate market. At the same time, greening promotion implementation method and urban policy standard both had a positive impact on the urban real estate market, demonstrating that government promotion of building environment greening design through urban design policy means is acceptable to the public.

A regulatory adjustment process for the determination of the optimal percentage requirement in an electricity market with Tradable Green Certificates

International Nuclear Information System (INIS)

Currier, Kevin M.

2013-01-01

A system of Tradable Green Certificates (TGCs) is a market-based subsidy scheme designed to promote electricity generation from renewable energy sources such as wind power. Under a TGC system, the principal policy instrument is the “percentage requirement,” which stipulates the percentage of total electricity production (“green” plus “black”) that must be obtained from renewable sources. In this paper, we propose a regulatory adjustment process that a regulator can employ to determine the socially optimal percentage requirement, explicitly accounting for environmental damages resulting from black electricity generation. - Highlights: • A Tradable Green Certificate (TGC) system promotes energy production from renewable sources. • We consider an electricity oligopoly operated under a TGC system. • Welfare analysis must account for damages from “black” electricity production. • We characterize the welfare maximizing (optimal) “percentage requirement.” • We present a regulatory adjustment process that computes the optimal percentage requirement iteratively

Full Text Available Green residential buildings (GRBs are one of the effective practices of energy saving and emission reduction in the construction industry. However, many real estate developers in China are less willing to develop GRBs, because of the factors affecting green residential building development (GRBD. In order to promote the sustainable development of GRBs in China, this paper, based on the perspective of real estate developers, identifies the influential and critical factors affecting GRBD, using the method of social network analysis (SNA. Firstly, 14 factors affecting GRBD are determined from 64 preliminary factors of three main elements, and the framework is established. Secondly, the relationships between the 14 factors are analyzed by SNA. Finally, four critical factors for GRBD, which are on the local economy development level, development strategy and innovation orientation, developer’s acknowledgement and positioning for GRBD, and experience and ability for GRBD, are identified by the social network centrality test. The findings illustrate the key issues that affect the development of GRBs, and provide references for policy making by the government and strategy formulation by real estate developers.

2017-09-01

Full Text Available Among the main environmental impacts of the operation of residential buildings are those due to greenhouse gases generation as a result of electric consumption of air conditioning systems. The use of vegetation systems in residential buildings represents an alternative to reduce this energy consumption. Green vegetation systems barriers are often used as protection against winds, but recently they are also being used as acoustic dampers. This work explores their use as thermal insulation systems for buildings. Specifically, we report the behavior of an Arundo donax green barrier as a bioclimatic element. The results are analyzed based on indoor and outdoor temperature measurement in prototype buildings, in function of the green barrier presence. Additionally Arundo donax transpiration under extreme environmental conditions was determined.

2016-01-01

Full Text Available Forward from the sustainability agenda of Brundtland in 1987 and the increasing demand for energy efficient buildings, the building industry has taken steps in meeting the challenge of reducing its environmental impact. Initiatives such as ‘green’ or ‘sustainable’ design have been at the forefront of architecture, while green assessment tools have been used to predict the energy performance of building during its operational phase. However, there is still a significant hap between predicted or simulated energy measurements compared to actual operational energy consumption, or is more commonly referred as the ‘performance gap’. This paper tries to bridge this gap by comparing measured operational energy consumption of a Green Building Index (GBI certified office building in Kuala Lumpur, with its predicted energy rating qualification.

Deregulation of the energy industry in the USA may be a force favouring the environment but for the consumer it is something of a nightmare since there are so many options with respect to both price, service and environmental awareness. However, there is now a marked tendency for companies wishing to be seen as 'green' to favour environmentally aware suppliers. Indeed, some suppliers holding formal qualifications in 'greenness' believe they are justified in charging a premium for their energy. The question is asked 'what is green?' and the authors discuss the answers at some length: the hydro industry fares well in such a discussion. The authors (from Scientific Certification Systems) believe that certification provides a rational explanation of prices and why charging a premium may be justifiable.(UK)

2012-12-01

Full Text Available The authors analyze the problem of implementation of principles of "green construction" in the Russian Federation. Despite the availability of the appropriate legislation in the field of environmental safety of construction, there are no legal, social, or economic incentives that may boost development of "green" technologies. Until recently, fundamentals of the state policy in the field of environmental protection of real estate development have not succeeded in motivating market players to implement advanced green technologies. However, recently, the government has begun motivating the construction industry towards the use of "green" technologies. The first activity is aimed at improving the legislation and updating the international voluntary certification according to BREAM and LEED standards. The result is the acceptance of the National Green Building Standard for real estate valuation that will open up new opportunities and prospects to the participants of the construction market. However, at the initial phase of implementation of "Fundamentals of the State Policy in the Field of Environmental Development of the Russian Federation", government authorities should provide their support to proponents of green buildings, including financial inflows.

The development of green building has been growing in both design and quality. The development of green building was limited by the issue of expensive investment. Actually, green building can reduce the energy usage inside the building especially in utilization of cooling system. External load plays major role in reducing the usage of cooling system. External load is affected by type of wall sheathing, glass and roof. The proper selection of wall, type of glass and roof material are very important to reduce external load. Hence, the optimization of energy efficiency and conservation in green building design is required. Since this optimization consist of integer and non-linear equations, this problem falls into Mixed-Integer-Non-Linear-Programming (MINLP) that required global optimization technique such as stochastic optimization algorithms. In this paper the optimized variables i.e. type of glass and roof were chosen using Duelist, Killer-Whale and Rain-Water Algorithms to obtain the optimum energy and considering the minimal investment. The optimization results exhibited the single glass Planibel-G with the 3.2 mm thickness and glass wool insulation provided maximum ROI of 36.8486%, EUI reduction of 54 kWh/m2·year, CO2 emission reduction of 486.8971 tons/year and reduce investment of 4,078,905,465 IDR.

Certification of power generation from sewage gas

Ronchetti, C.

2004-01-01

This article discusses the certification of power generated from sewage gas in packaged co-generation units in Switzerland. Since 2003, such electricity can be sold as 'green power' to consumers, who pay an additional charge for this ecologically generated power. Since the eco-balance of this electricity generated in wastewater treatment plant is considered as being excellent, the prestigious 'Naturemade Star' label has been awarded to it. This label sets most stringent requirements. The Canius wastewater treatment plant in the 'Lenzerheide' in eastern Switzerland is taken as an example to illustrate the procedure that has to be gone through to receive certification. This certification is carried out by independent auditors and guarantees that the 'green' electricity offered by the utility meets the high ecological criteria set by the label

2015-03-01

Full Text Available Delivering green building (GB projects involve some activities that are atypical in comparison with conventional buildings. Such new activities are characterized by uncertainty, and they incur hidden costs that have not been expected nor are they readily appreciated among the stakeholders. This paper develops a typology and chronology to examine the new activities that are associated with transaction costs (TCs in the real estate development process (REDP of green building. Through in-depth interviews with representatives from the major developers in Hong Kong who have experiences in GB practice, this study aims to unearth TCs involved at the critical stages of the REDP. Apart from reconfirming the early project planning stage as the most critical in the consideration of TCs, the study results also identified “extra legal liability risk of the GB product” as the major concern for any GB developer in Hong Kong. The key additional activities that bring significant TCs in developing GB are identified and compared to their traditional counterparts. In turn, project managers not only have to pursue overall cost management whilst winning more business, but they also have to pay particular attention to sustainability in order to minimize hidden societal costs. The study also provides a reference for governments and professionals that will aid in forming policy as well as advance the practice of the GB market by optimizing the societal costs.

Overcoming barriers to high performance seismic design using lessons learned from the green building industry

Science.gov (United States)

Glezil, Dorothy

NEHRP's Provisions today currently governing conventional seismic resistant design. These provisions, though they ensure the life-safety of building occupants, extensive damage and economic losses may still occur in the structures. This minimum performance can be enhanced using the Performance-Based Earthquake Engineering methodology and passive control systems like base isolation and energy dissipation systems. Even though these technologies and the PBEE methodology are effective reducing economic losses and fatalities during earthquakes, getting them implemented into seismic resistant design has been challenging. One of the many barriers to their implementation has been their upfront costs. The green building community has faced some of the same challenges that the high performance seismic design community currently faces. The goal of this thesis is to draw on the success of the green building industry to provide recommendations that may be used overcome the barriers that high performance seismic design (HPSD) is currently facing.

City of Austin: Green habitat learning project. A green builder model home project

The purpose of the Year 14 UCETF project was to design and construct a residential structure that could serve as a demonstration facility, training site, and testing and monitoring laboratory for issues related to the implementation of sustainable building practices and materials. The Model Home Project builds on the previous and existing efforts, partially funded by the UCETF, of the City of Austin Green Builder Program to incorporate sustainable building practices into mainstream building activities. The Green Builder Program uses the term {open_quotes}green{close_quotes} as a synonym for sustainability. In the research and analysis that was completed for our earlier reports in Years 12 and 13, we characterized specific elements that we associate with sustainability and, thus, green building. In general, we refer to a modified life cycle assessment to ascertain if {open_quotes}green{close_quotes} building options reflect similar positive cyclical patterns found in nature (i.e. recyclability, recycled content, renewable resources, etc.). We additionally consider economic, human health and synergistic ecological impacts associated with our building choices and characterize the best choices as {open_quotes}green.{close_quotes} Our ultimate goal is to identify and use those {open_quotes}green{close_quotes} materials and processes that provide well for us now and do not compromise similar benefits for future generations. The original partnership developed for this project shifted during the year from a project stressing advanced (many prototypical) {open_quotes}green{close_quotes} building materials and techniques in a research and demonstration context, to off-the-shelf but underutilized {open_quotes}green{close_quotes} materials in the practical social context of using {open_quotes}green{close_quotes} technologies for low income housing. That project, discussed in this report, is called the Green Habitat Learning Project.

This paper presents a study in a Norwegian perspective of the political proposal for a common mandatory electricity certificate market between Norway and Sweden. The proposal was withdrawn in February 2006. The study examines whether Prime Minister Jens Stoltenberg's second government assessed green certificates as the cause of an unpopular hike in electricity prices, a hypothesis that found some support in this work. Next, it examines the role of the government bureaucracy. A hypothesis is set forth that the government decision followed from standard operational procedures in the bureaucracy. Importantly, the Ministry of Finance and the Ministry of Petroleum and Energy, the most significant bureaucratic agents in our case, made their recommendations based on economic principles, which had become a standard operating procedure for them in Norwegian energy and environmental policies.

Greening government procurement in developing countries: building capacity in China.

Science.gov (United States)

Geng, Yong; Doberstein, Brent

2008-09-01

With increasing environmental issues and depleting resources, the effective application of green government procurement (GGP) is urgently needed and potentially can have greater impacts in the developing world rather than in the developed world. Such an approach can help promote the general goal of sustainable development and address environmental issues through purchasing and facilitating the use of environmentally friendly services and products. This paper addresses this issue by employing a case study on China. We first trace the development of the GGP concept, its spread to Asian countries, and a number of approaches used to expand GGP adoption. We then review current practices in China on GGP, and analyze and identify some of the current barriers and problems in promoting green procurement in the Chinese governmental sector. We finally seek to identify possible appropriate capacity-building solutions, in order to facilitate the application of GGP in China.

A lignite-geothermal hybrid power and hydrogen production plant for green cities and sustainable buildings

Energy Technology Data Exchange (ETDEWEB)

Kilkis, B. [Baskent University, Ankara (Turkey). Dept. of Mechanical Engineering

2011-02-15

Turkey is rich in both geothermal energy and lignite reserves, which in many cases, are co-located. This condition makes it feasible to utilize both lignite and geothermal energy in a hybrid form for combined power heat, and cold generation, which may lead to optimally energy and exergy efficient, environmentally benign, and economically sound applications. This paper presents a novel concept of hybrid lignite-geothermal plant for a district energy system and hydrogen production facility in Aydin with special emphasis on high performance, green buildings and green districts. In this concept, lignite is first introduced to a partially fluidized-bed gasifier and then to a fluidized-bed gas cleaning unit, which produces synthetic gas and finally hydrogen. The by-products, namely char and ash are used in a fluidized-bed combustor to produce power. Waste heat from all these steps are utilized in a district heating system along with heat received from geothermal production wells after power is generated there. H{sub 2}S gas obtained from the separator system is coupled with hydrogen production process at the lignite plant. Absorption cooling systems and thermal storage tanks complement the hybrid system for the tri-generation district energy system. On the demand side, the new, green OSTIM OSB administration building in Ankara is exemplified for greener, low-exergy buildings that will compound the environmental benefits.

Methodology for forecasting in the Swedish–Norwegian market for el-certificates

International Nuclear Information System (INIS)

Wolfgang, Ove; Jaehnert, Stefan; Mo, Birger

2015-01-01

In this paper we describe a novel methodology for forecasting in the Swedish–Norwegian el-certificate market, which is a variant of a tradable green certificate scheme. For the forecasting, the el-certificate market is integrated in the electricity-market model EMPS, which has weekly to hourly time-step length, whereas the planning horizon can be several years. Strategies for the certificate inventory are calculated by stochastic dynamic programming, whereas penalty-rates for non-compliance during the annual settlement of certificates are determined endogenously. In the paper the methodology is described, and we show the performance of the model under different cases that can occur in the el-certificate market. The general results correspond to theoretical findings in previous studies for tradable green certificate markets, in particular that price-scenarios spread out in such a way that the unconditional expected value of certificates is relatively stable throughout the planning period. In addition the presented methodologies allows to assess the actual dynamics of the certificate price due to climatic uncertainty. Finally, special cases are indentified where the certificate price becomes excessively high respectively zero, due the design-specific dynamics of the penalty rate. - Highlights: • A method for forecasting in the Swedish–Norwegian el-certificate market is proposed. • The developed model integrates the el-certificate and the power market. • Banking of certificates and the endogenously calculated penalty rate are included. • The certificate value is calculated using Stochastic-Dynamic-Programming. • Price dynamics due to climatic weather uncertainties are assessed and illustrated

Green Roofs and Green Walls for Biodiversity Conservation: A Contribution to Urban Connectivity?

Directory of Open Access Journals (Sweden)

Flavie Mayrand

2018-03-01

Full Text Available Green roofs and walls have recently emerged as conservation tools, and they offer promising additional opportunities to enhance biodiversity in cities. However, their ecological conditions remain poorly considered when planning wildlife corridors. To discuss the role of vegetated buildings in landscape connectivity, we reviewed the ecological and technical specificities of green walls and green roofs in light of the key factors concerning urban wildlife (patch size, quality, abundance, and isolation. Green roofs and walls show limited patch sizes, distinct habitat quality at the building scale, and limited redundancy of patch quality within the landscape. We also highlight that the abundance of roof and wall patches is often low. Future research is needed to establish if walls can be vertical corridors for wildlife, thereby reducing the isolation of green roofs. We argue that creating 3D ecological connectivity within the city requires substantial modifications of the design and maintenance of existing green building systems. We suggest that research is needed to integrate the biotic and abiotic characteristics of green buildings to make them more closely resemble those of open green spaces.

Tradable certificates for renewable electricity and energy savings

International Nuclear Information System (INIS)

Bertoldi, Paolo; Huld, Thomas

2006-01-01

Tradable green certificates (TGCs) schemes have been developed and tested in several European countries to foster market-driven penetration of renewables. These certificates guarantee that a specific volume of electricity is generated from renewable-energy source (RES). More recently certificates (tradable white certificates (TWCs)) for the electricity saved by demand-side energy-efficiency measures (EEMs) have been introduced in some European countries. Recent advances in information and communication technology have opened up new possibilities for improving energy efficiency and increasing utilization of RESs. Use of technological resources such as the Internet and smart metering can permit real-time issuing and trading of TGCs. These technologies could also permit issuing of TWC. This paper reviews current renewable TGC and TWCs schemes in Europe and describes the possibilities for combining them in an Internet-based system. In the proposed combined tradable certificate scheme, both RESs and demand-side EEMs could bid in real time through the Internet to meet a specific obligation. The energy savings from the demand-side measures would be equivalent to the same amount of green electricity production. The paper describes the needed common targets and obligations, the certificate trading rules and the possible monitoring protocol. In particular, the paper focuses on the TWCs verification issues, including the assessment of the baseline, as these poses additional problems for TWCs compared to TGCs. (author)

Energy Performance Certificate of building and confidence interval in assessment: An Italian case study

International Nuclear Information System (INIS)

Tronchin, Lamberto; Fabbri, Kristian

2012-01-01

The Directive 2002/91/CE introduced the Energy Performance Certificate (EPC), an energy policy tool. The aim of the EPC is to inform building buyers about the energy performance and energy costs of buildings. The EPCs represent a specific energy policy tool to orient the building sector and real-estate markets toward higher energy efficiency buildings. The effectiveness of the EPC depends on two factors: •The accuracy of energy performance evaluation made by independent experts. •The capability of the energy classification and of the scale of energy performance to control the energy index fluctuations. In this paper, the results of a case study located in Italy are shown. In this example, 162 independent technicians on energy performance of building evaluation have studied the same building. The results reveal which part of confidence intervals is dependent on software misunderstanding and that the energy classification ranges are able to tolerate the fluctuation of energy indices. The example was chosen in accordance with the legislation of the Emilia-Romagna Region on Energy Efficiency of Buildings. Following these results, some thermo-economic evaluation related to building and energy labelling are illustrated, as the EPC, which is an energy policy tool for the real-estate market and building sector to find a way to build or retrofit an energy efficiency building. - Highlights: ► Evaluation of the accuracy of energy performance of buildings in relation with the knowledge of independent experts. ► Round robin test based on 162 case studies on the confidence intervals expressed by independent experts. ► Statistical considerations between the confidence intervals expressed by independent experts and energy simulation software. ► Relation between “proper class” in energy classification of buildings and confidence intervals of independent experts.

Defining and certifying green power

International Nuclear Information System (INIS)

1998-02-01

Studies have shown that as electric utilities restructure from monopolistic utilities to competitive open access retailers, there is an increasing demand by individual and institutional customers for green power. In the United States, 17 electricity suppliers have offered customers the opportunity to buy energy generated from renewable sources such as photovoltaic panels, wind turbines and biomass. Twenty other utilities are conducting market research in preparation for offering a similar program. It was suggested that in order to help the customers make their choice based on accurate information, generating facilities should be obligated to provide credible information about the environmental performance of electricity supply through standardized environmental profile labels. A list of agreed upon environmental indicators and performance levels must be established so that the 'environmental friendliness' of different generating facilities can be measured. One of the problems in tackling this issue is that there is disagreement about what constitutes green power. Opinions range from wind and solar generation being the only two forms of green power, to including even natural gas and nuclear energy (i.e. under the right conditions). The two programs that are used for the certification of green power in Canada and the United States are Canada's Environmental Choice Program and California's Green-e Renewable Electricity Branding Program. This report describes the two programs and summarizes the results of interviews conducted on the definition and certification of green power. 15 refs

Towards green buildings: Glass as a building element-the use and misuse in the gulf region

Energy Technology Data Exchange (ETDEWEB)

Aboulnaga, Mohsen M. [College of Design and Applied Arts, Dubai University College, Dubai P.O. Box 14143 (United Arab Emirates)

2006-04-15

The recent economic growth in the Gulf region notably in Dubai, United Arab Emirates (UAE) has led to a colossal number of buildings that has been constructed in the past 5 years. In the last decade, a total glazed building's facades became the icon of Dubai. This large area of glazing in each facade needs protection against overheating and sun glare in summer. According to leader in energy and environmental design (LEED) glass selection becomes a main element in this equation to contribute towards achieving a green building. The aim of this paper is to investigate the problems associated with misuse of glass, as a building element in UAE particularly in Dubai. Inadequate design with ill-selected glass/glazing type may lead not only to poor daylighting in building interiors but also contribute significantly to fatigue, insomnia, seasonal affective disorder (SAD) and above all increase CO{sub 2} emission. The purpose of the study is to specify the required improvements to permit natural, 'free' daylight to filter through the building facade into interior space, especially with the right type of glass. This paper examines the status of buildings in Dubai in terms of glass type, visible light transmittance, reflection (out/in) and relative heat gain. A quantitative analysis is conducted to assess the impact of glass on the building users' performance in terms of daylight environment. A recent built high-rise office building was selected in the investigation to asses whether selected glass provide the recommended daylight factor (DF) and daylight level (DL) according to IES standards. The results revealed that most the glass/glazing was misused in 70% of buildings in intermediate and low performance groups. The DF and DD in the selected office building were unexpectedly tremendous and found far beyond the recommended level due to the use of spectrally selective glazing (clear on both sides). [Author].

Intelligent Facades for High Performance Green Buildings. Final Technical Report

Dyson, Anna [Rensselaer Polytechnic Inst., Troy, NY (United States)

2017-03-01

Intelligent Facades for High Performance Green Buildings: Previous research and development of intelligent facades systems has been limited in their contribution towards national goals for achieving on-site net zero buildings, because this R&D has failed to couple the many qualitative requirements of building envelopes such as the provision of daylighting, access to exterior views, satisfying aesthetic and cultural characteristics, with the quantitative metrics of energy harvesting, storage and redistribution. To achieve energy self-sufficiency from on-site solar resources, building envelopes can and must address this gamut of concerns simultaneously. With this project, we have undertaken a high-performance building- integrated combined-heat and power concentrating photovoltaic system with high temperature thermal capture, storage and transport towards multiple applications (BICPV/T). The critical contribution we are offering with the Integrated Concentrating Solar Façade (ICSF) is conceived to improve daylighting quality for improved health of occupants and mitigate solar heat gain while maximally capturing and transferring on- site solar energy. The ICSF accomplishes this multi-functionality by intercepting only the direct-normal component of solar energy (which is responsible for elevated cooling loads) thereby transforming a previously problematic source of energy into a high- quality resource that can be applied to building demands such as heating, cooling, dehumidification, domestic hot water, and possible further augmentation of electrical generation through organic Rankine cycles. With the ICSF technology, our team is addressing the global challenge in transitioning commercial and residential building stock towards on-site clean energy self-sufficiency, by fully integrating innovative environmental control systems strategies within an intelligent and responsively dynamic building envelope. The advantage of being able to use the entire solar spectrum for

A Comparative Analysis of Policy Instruments Promoting Green Electricity under Uncertainty

International Nuclear Information System (INIS)

Carlen, Bjoern

2006-07-01

The paper presented here studies, in a more systematic way than previous literature, the implications uncertainty regarding i.a. future production costs of green as well as conventional electricity has on the optimal choice of instrument to promote production of green electricity. The objective is to identify relevant effects the regulator need to assess before being able to make an informed choice. The instruments studied are (i) a feed-in tariff, i.e., an obligation for retailers of electricity to buy whatever quantity of green electricity that is supplied at a price determined by the regulator, (ii) a so-called environmebonus; , i.e., a fixed premium to producers of green electricity over and above the market price on electricity, (iii) an obligation for the retailers to procure a certain quantity of green electricity, and (iv) green electricity certificates, i.e., an obligation for retailers to purchase green electricity in an amount equal to a given share of their total electricity sale. It has been suggested, in the literature on instruments to promote production of green electricity, that price-based policies (e.g., fixed-in tariffs) would be superior to quantity-based policies (e.g., an obligation on retailers of electricity to procure a given amount of green electricity). The stated reason is that quantity-based policies tend to induce too much (little) green electricity whenever production costs turn out to be higher (lower) than expected. However, price-based policies, on the other hand, induces too little (much) green electricity, and, as shown here quantity-based policies can be designed in ways making them superior to a fixed feed-in tariff in the sense of yielding a smaller expected efficiency loss. It is also shown here that green electricity certificate system and systems with so-called environmental bonuses are more complicated policy instruments than so far has been recognized. If future electricity prices are highly uncertain, an environmental

We examined associations of several health outcomes with green and conventional low-income housing, where the prevalence of morbidities and environmental pollutants is elevated. We used questionnaires and a visual inspection to compare sick building syndrome (SBS) symptoms and asthma-related morbidity among residents in multifamily units in Boston, Massachusetts, between March 2012 and May 2013. Follow-up was approximately 1 year later. Adults living in green units reported 1.35 (95% confidence interval [CI] = 0.66, 2.05) fewer SBS symptoms than those living in conventional (control) homes (P green homes experienced substantially lower risk of asthma symptoms (odds ratio [OR] = 0.34; 95% CI = 0.12, 1.00), asthma attacks (OR = 0.31; 95% CI = 0.11, 0.88), hospital visits (OR = 0.24; 95% CI = 0.06, 0.88), and asthma-related school absences (OR = 0.21; 95% CI = 0.06, 0.74) than children living in conventional public housing. Participants living in green homes had improved health outcomes, which remained consistent over the study period. Green housing may provide a significant value in resource-poor settings where green construction or renovation could simultaneously reduce harmful indoor exposures, promote resident health, and reduce operational costs.

Feed in or certificates, competition or complementarity? Combining a static efficiency and a dynamic innovation perspective on the greening of the energy industry

International Nuclear Information System (INIS)

Midttun, Atle; Gautesen, Kristian

2007-01-01

European policy on the greening of the energy industry has been characterised by a debate between proponents of two apparent polar opposites, feed in tariffs and certificate markets. Different European countries have chosen both mechanisms and, as a consequence, the European Union has maintained a fairly pluralist position, abstaining from stricter harmonisation. Taking a dynamic innovation perspective on European energy industry, we argue that feed in tariffs and certificate markets should not be seen as competing alternatives, but rather as complementary regulatory instruments targeting subsequent steps in the product cycle, on the way from early technology-conceptualisation and development towards competitive positioning in mature energy markets. We see both policy instruments as necessary to achieve the extensive transformation towards sustainable development that is judged as important tools in the context of the global climate challenge

Health Co-Benefits of Green Building Design Strategies and Community Resilience to Urban Flooding: A Systematic Review of the Evidence.

Science.gov (United States)

Houghton, Adele; Castillo-Salgado, Carlos

2017-12-06

Climate change is increasingly exacerbating existing population health hazards, as well as resulting in new negative health effects. Flooding is one particularly deadly example of its amplifying and expanding effect on public health. This systematic review considered evidence linking green building strategies in the Leadership in Energy and Environmental Design ® (LEED) Rating System with the potential to reduce negative health outcomes following exposure to urban flooding events. Queries evaluated links between LEED credit requirements and risk of exposure to urban flooding, environmental determinants of health, co-benefits to public health outcomes, and co-benefits to built environment outcomes. Public health co-benefits to leveraging green building design to enhance flooding resilience included: improving the interface between humans and wildlife and reducing the risk of waterborne disease, flood-related morbidity and mortality, and psychological harm. We conclude that collaborations among the public health, climate change, civil society, and green building sectors to enhance community resilience to urban flooding could benefit population health.

Analysis of implementation of Tradable Green Certificates system in a competitive electricity market: a game theory approach

Science.gov (United States)

Ghaffari, Meysam; Hafezalkotob, Ashkan; Makui, Ahmad

2016-06-01

This paper investigates three models to implement Tradable Green Certificates (TGC) system with aid of game theory approach. In particular, the competition between thermal and renewable power plants is formulated in three models: namely cooperative, Nash and Stackelberg game models. The price of TGC is assumed to be determined by the legislative body (government) which is fixed. Numerical examples presented in this paper include sensitivity analysis of some key parameters and comparison of the results of different models. In all three game models, the parameters that influence pricing of the TGC based on the optimal amounts are obtained. The numerical examples demonstrate that in all models: there is a reverse relation between the price of electricity and the TGC price, as well as a direct relation between the price of electricity and the share of green electricity in total electricity generation. It is found that Stackelberg model is an appropriate structure to implement the TGC system. In this model, the supply of electricity and the production of green electricity are at the highest level, while the price of electricity is at the lowest levels. In addition, payoff of the thermal power plant is at the highest levels in the Nash model. Hence this model can be an applicatory structure for implementation of the TGC system in developing countries, where the number of thermal power plants is significantly greater than the number of renewable power plants.

Al-Ghamdi, Sami G; Bilec, Melissa M

2016-05-03

Adopting a green building rating system (GBRSs) that strongly considers use of renewable energy can have important environmental consequences, particularly in developing countries. In this paper, we studied on-site renewable energy and GBRSs at the system level to explore potential benefits and challenges. While we have focused on GBRSs, the findings can offer additional insight for renewable incentives across sectors. An energy model was built for 25 sites to compute the potential solar and wind power production on-site and available within the building footprint and regional climate. A life-cycle approach and cost analysis were then completed to analyze the environmental and economic impacts. Environmental impacts of renewable energy varied dramatically between sites, in some cases, the environmental benefits were limited despite the significant economic burden of those renewable systems on-site and vice versa. Our recommendation for GBRSs, and broader policies and regulations, is to require buildings with higher environmental impacts to achieve higher levels of energy performance and on-site renewable energy utilization, instead of fixed percentages.

Full Text Available Research objective is to conceive, design and experiment a strategy at wide city scale to contribute facing the global ecological and energy crises of the Planet. This should be done through structural cut-down of fossil fuel consumption for settlements, i.e. by adopting the lowest cost energy: the not-consumed one! According to the Green Building Practices there are goals that can be achieved mainly through building passivation connected to: application of state-of-the-art sustainable technologies; alternative energy sources; diffusion of zero-mile decentralized solar energy production; fostering-up of solar feeding for summer air-conditioning, i.e. one of the most demanding energy consumers of the world. Owners, investors, contractors, occupants, tenants ask for more information and better quantification of energy saving magnitude in Green Buildings, as well as further appraisal of pay-back period i.e the length of time required for the return or re-payment of the additional larger initial investment. Research tries to conceive a methodology to assess in physical and monetary terms the energy saving and to define in financial terms the initial investment pay-back period at a reasonable rate. Proposed methodology has been tested in a first Case Study set-up at urban level and performed on a urban blocks of a Mediterranean medium size town including real world prototype yard, i.e. chantier, integrating passivation with the adoption of key frontier technologies such as sun chiller and solar cooling.

Ozone reactions that occur on material surfaces can lead to elevated concentrations of oxidized products in the occupied space of buildings. However, there is little information on the impact of materials at full scale, especially for green building materials. Experiments were completed in a 68 m3 climate-controlled test chamber with three certified green building materials that can cover large areas in buildings: (1) recycled carpet, (2) perlite-based ceiling tile and (3) low-VOC paint and primer on recycled drywall. Ozone deposition velocity and primary and secondary emission rates of C1 to C10 saturated carbonyls were determined for two chamber mixing conditions and three values of relative humidity. A direct comparison was made between ozone deposition velocities and carbonyl yields observed for the same materials analyzed in small (10 L) chambers. Total primary carbonyl emission rates from carpet, ceiling tile and painted drywall ranged from 27 to 120 μg m-2 h-1, 13 to 40 μg m-2 h-1, 3.9 to 42 μg m-2 h-1, respectively. Ozone deposition velocity to these three materials averaged 6.1 m h-1, 2.3 m h-1 and 0.32 m h-1, respectively. Total secondary carbonyl emissions from these materials ranged from 70 to 276 μg m-2 h-1, 0 to 12 μg m-2 h-1, and 0 to 30 μg m-2 h-1, respectively. Carbonyl emissions were determined with a transient approximation, and were found to be in general agreement with those found in the literature. These results suggest that care should be taken when selecting green building materials due to potentially large differences in primary and secondary emissions.

This paper deals with the experimental investigation and analysis of the energy and environmental performance of a green roof system installed in a nursery school building in Athens. The investigation was implemented in two phases. During the first phase, an experimental investigation of the green roof system efficiency was presented and analysed, while in the second one the energy savings was examined through a mathematical approach by calculating both the cooling and heating load for the summer and winter period for the whole building as well as for its top floor. The energy performance evaluation showed a significant reduction of the building's cooling load during summer. This reduction varied for the whole building in the range of 6-49% and for its last floor in the range of 12-87%. Moreover, the influence of the green roof system in the building's heating load was found insignificant, and this can be regarded a great advantage of the system as any interference in the building shell for the reduction of cooling load leads usually to the increase of its heating load.

Full Text Available There are many iconic high rise buildings in Hong Kong, for example, International Commercial Centre, International Financial Centre, etc. Fire safety issue in high rise buildings has been raised by local fire professionals in terms of occupant evacuation, means of fire-fighting by fire fighters, sprinkler systems to automatically put off fires in buildings, etc. Fire risk becomes an important issue in building fire safety because it relates to life safety of building occupants where they live and work in high rise buildings in Hong Kong. The aim of this research is to identify the fire risk for different types of high rise buildings in Hong Kong and to optimise the fire prevention management for those high rise buildings with higher level of fire risk and to validate the model and also to carry out the study of the conflict between the current fire safety building code and the current trend of green building design. Survey via the 7-point scale questionnaire was conducted through 50 participants and their responses were received and analysed via the statistical tool SPSS software computer program. A number of statistical methods of testing for significantly difference in samples were adopted to carry out the analysis of the data received. When the statistical analysis was completed, the results of the data analysis were validated by two Fire Safety Experts in this area of specialisation and also by quantitative fire risk analysis.

Several solutions, ranging from increased technician duties to salary raises, automation, and increasing job satisfaction, have been presented in the literature as methods of assuaging the pharmacist shortage. Although a significant portion of pharmacy graduates from American pharmacy colleges are foreign nationals, no marketing strategies have been elucidated in the retention and recruitment of foreign nationals through labor certification. Labor certifications are generally approved by the Secretary of Labor if the following factors have been verified: 1) there are not sufficient United States workers who are able, willing, qualified, and available for employment; and 2) the employment of the foreign national will not adversely affect the wages and working conditions of U.S. workers similarly employed. When properly understood, the labor certification process is a test of the job market where foreigners, by virtue of their skills and qualifications, attain certification which subsequently leads to permanent residency (green card). The objective of this report is to elucidate the tedious yet effective method of retaining American-educated foreign nationals through labor certification.

At 5th November 2009, the REWE Group (Cologne, Federal Republic of Germany) started the first Green Building in Berlin-Rudow (Federal Republic of Germany). Thus, the REWE Group sets a standard for a sustainable construction and operation of commercial immovables. The German Sustainable Building Council (Stuttgart, Federal Republic of Germany) distinguished this pilot project with the certificate in gold. The building is operated CO{sub 2} neutrally by means of most modern heating systems, ventilation systems, lighting systems, air conditioning systems and refrigerant plants in combination with an optimum insulation. Compared with a standard building, the energy consumption is reduced by nearly 50 per cent. The practice realizations are to be used in order to define a strategy for the future rollout of the total concept or certain concept components on a long-term basis.

BREEAM [Building Research Establishment Environmental Assessment Method] BRE [Building Research Establishment] assessment method for buildings

International Nuclear Information System (INIS)

Baldwin, R.

1994-01-01

Buildings account for a large share of environmental impacts in their construction, use, and demolition. In western Europe, buildings account for ca 50% of primary energy use (hence CO 2 output), far outweighing the contribution of the transport and industrial sectors. Other impacts from building energy use include the use of chemicals such as chlorofluorocarbons for cooling. In the United Kingdom, the Building Research Establishment (BRE) has developed a certificate system for environmental labelling of buildings so that the performance of the building against a set of defined environmental criteria can be made visible to clients. This system thus rewards positive actions to improve the environmental performance of buildings and assists in marketing to an environmentally aware clientele. Issues included in assessments for awarding the certificate are addressed under three main headings: global issues and use of resources, local issues, and indoor issues. Global issues include ozone depletion and CO 2 emissions; local issues include public health and water conservation; and indoor issues include air quality and lighting. 8 refs., 1 tab

Multi-layer planting as a strategy of greening the transitional space in high-rise buildings: A review

Science.gov (United States)

Prihatmanti, Rani; Taib, Nooriati

2018-03-01

The issues regarding the rapid development in the urban have resulted in the increasing number of infrastructure built, including the high-rise buildings to accommodate the urban dwellers. Lack of greeneries due to the land limitation in the urban area has increased the surface radiation as well as the air temperature that leads to the Urban Heat Island (UHI) phenomena. Where urban land is limited, growing plants vertically could be a solution. Plants, which are widely known as one of the sustainability elements in the built environment could be integrated in building as a part of urban faming by growing edible plant species. This is also to address the food security issue in the urban as well as high-density cities. Since space is limited, the function of transitional space could be optimized for the green space. This paper explores the strategy of greening transitional space in the high-rise setting. To give a maximum impact in a limited space, multi-layer planting concept could be introduced. This concept is believed that multiple layers of plants could modify the microclimate, as well as the radiation to the building, compare to single layer plant. In addition to that, the method selected also determines the efficacy of the vertical greeneries. However, there are many other limitations related to the multi-layer planting method if installed in a transitional space that needs to be further studied. Despite its limitations, the application of vertical greeneries with multi-layer planting concept could be a promising solution for greening the limited space as well as improving the thermal comfort in the high-rise building.

Contradictions of increasing carbon mitigation pressure and electricity demand have been aggravated significantly. A heavy emphasis is placed on analyzing the carbon mitigation potential of electric energy systems via tradable green certificates (TGC). This study proposes a tradable green certificate (TGC)-fractional fuzzy stochastic robust optimization (FFSRO) model through integrating fuzzy possibilistic, two-stage stochastic and stochastic robust programming techniques into a linear fractional programming framework. The framework can address uncertainties expressed as stochastic and fuzzy sets, and effectively deal with issues of multi-objective tradeoffs between the economy and environment. The proposed model is applied to the major economic center of China, the Beijing-Tianjin-Hebei region. The generated results of proposed model indicate that a TGC mechanism is a cost-effective pathway to cope with carbon reduction and support the sustainable development pathway of electric energy systems. In detail, it can: (i) effectively promote renewable power development and reduce fossil fuel use; (ii) lead to higher CO 2 mitigation potential than non-TGC mechanism; and (iii) greatly alleviate financial pressure on the government to provide renewable energy subsidies. The TGC-FFSRO model can provide a scientific basis for making related management decisions of electric energy systems. Copyright © 2017 Elsevier B.V. All rights reserved.

Contribution of green labels in electricity retail markets to fostering renewable energy

International Nuclear Information System (INIS)

Mulder, Machiel; Zomer, Sigourney P.E.

2016-01-01

In European countries, retailers are obliged to disclose the energy source and the related environmental impacts of their portfolio over the preceding year. The electricity supplied in the Dutch retail market is presented as renewable energy for 34%, but this relatively high share is for 69% based on certificates (Guarantees of Origin) which are imported from in particular Norway. The certificates are used to sell green electricity to consumers. The premium for green electricity which is actually paid by Dutch consumers is no more than a few percentages of the retail price. The low level of this premium is related to the abundant supply of certificates at low marginal costs from Norway. This also means that the premium for green electricity is too low to give an incentive for investments in new capacity. Hence, the current labelling system for renewable electricity is mainly valuable, besides being an instrument for tracking and tracing of renewable energy, as a marketing instrument for electricity retailers. The effectiveness of Guarantees of Origin as a policy instrument to foster renewable electricity sources is weak. This effectiveness can be raised by implementing restrictions on the international trade or the issuance of new certificates. - Highlights: • In Europe, electricity retailers are obliged to disclose the energy source. • In the Netherlands, most renewable energy is based on imported certificates. • The certificates system does not result in more renewable energy. • Restrictions on international trade may improve the effectiveness.

Yamagata, Y.; Murakami, D.

2016-12-01

The "Paris Agreement" requires major carbon emitting countries to conduct massive reduction efforts during the 21st century. At the same time, new carbon financing mechanisms are emerging. Among others, Green Bonds (GBs) is rapidly developing. In this paper, we discuss about the potential use of GBs for financing city level carbon management. In order to make the application effective, there are several issues to be studied with financial and environmental researchers together. Especially at city level, it is necessary to develop new GBs assessment methods to check the comprehensive environmental implications of the GBs projects. For this purpose, we discuss about the enhancement of currently developing district level Green Building standards and certification systems (LEED-ND). We also report about our new research results regarding city scale monitoring system (CO2, energy, transport, ecosystem etc.) for the reporting. *This paper is related to a Future Earth (Global Carbon Project) project proposal. It is also linked with development regarding the Knowledge Action Networks.

Toronto green roof construction standard

International Nuclear Information System (INIS)

Aster, D.

2007-01-01

Toronto City Council adopted a green roof strategy in February 2006. This paper reviewed the by-law governing the strategy as well as the work in progress to develop minimum standards for the design and construction of green roofs in Toronto. The strategy included a series of recommendations regarding the installation of green roofs on city buildings; a pilot grant program; using the development process to encourage green roofs; and, public education and promotion. It was noted that compared to Europe, the development of standards for green roofs in North America is in its early stages. As an emerging sustainable technology, there currently are no standards incorporated into Ontario's Building Code against which Toronto can measure the design and construction of green roofs. Therefore this paper included an analysis detailing how the recommended design requirements were able to support the City's green roof policy objectives and integrate the performance criteria for green roofs previously established and supported by Toronto City Council. The key policy objectives of the City's green roof strategy were to reduce the urban heat island effect; to address stormwater management implications in terms of quality and quantity; to improve the energy budgets of individual buildings; and, to improve air quality

Eco-certification and greening the Brazilian soy and corn supply chains

VanWey, Leah K.; Richards, Peter D.

2014-03-01

Garrett et al’s recent letter (2013 Environ. Res. Lett. 8 044055) shows the trade value of Brazil’s production of non-genetically modified (GM) crops, and argues that production for this niche market laid the foundation for the expansion of a variety of non-GM and eco-certification systems. We argue that the conditions underlying the development and perpetuation of the non-GM certification systems are transient. The expansion of soy production has dampened the conditions that promoted the dominance of non-GM soy in the region. The state at the heart of the production of conventional soy, Mato Grosso, already has transitioned to almost 90% GM soy in the most recent agricultural season. The continued viability of eco-certification systems depends on strengthening institutions on the demand side, and ensuring farm-level costs on the supply side match price premiums reaching the farm level.

Full Text Available During the last ten years, the growth of apartment buildings in Surabaya has encountered the bitter experience of global warming, resource depletion, energy scarcity, and other environmental impacts. We cannot avoid them, but we can minimize the negative impacts of global warming. The green building concept is one of the methods to minimize the environmental impact. It takes into account principles of sustainable development in planning, construction, operation, and maintenance. Greenship Rating Tools is used to evaluate and calculate green achievements, prior to green building certification. The aim of this research is to represent the perceptions of contractors and consultants toward application of Greenship Rating Tools on apartment buildings in Surabaya. Based on the data obtained from a questionnaires survey carried out to 41 respondents, the mean value ranking method is used to evaluate the main factors of Greenship. These factors are Appropriate Site Development, Energy Efficiency and Conservation, Water Conservation, Material Resource and Cycle, Indoor Health and Comfort, and Building Environmental Management. In general, the results of this research show that there are a number of differences between perceptions of contractors and consultants toward application of Greenship Rating Tools on apartment buildings in Surabaya. According to the contractors’ perception, Visual Comfort is a factor that would easily to be applied, whilst consultants’ is Landscape. On the other hand, there are factors that would difficult to be applied. Based on contractors’ perceptiom is Climate Change, while consultants’ perception is Renewal Energy. In summary, Greenship Rating Tools can be applied on contractors’ and consultants’ perceptions, whilst there are some variables which can not be applied.

Promoting green design, construction, reconstruction and operation of buildings has never been more critical than now due to the ever increasing greenhouse gas emissions and rapid urbanizations that are fuelling climate change more quickly. Driven by environmental needs, Green Building Index (GBI) was founded in Malaysia to drive initiative to lead the property industry towards becoming more environment-friendly. Green roof system is one of the assessment criteria of this rating system which is under category of sustainable site planning and management. An extensive green roof was constructed in Humid Tropics Center (HTC) Kuala Lumpur as one of the components for Stormwater Management Ecohydrology (SME) in order to obtain scientific data of the system. This paper evaluates the performance of extensive green roof at Humid Tropics Center with respect to urban heat island mitigation and stormwater quantity and quality controls. Findings indicate that there was a reduction of around 1.5°C for indoor temperature of the building after installation of green roof. Simulations showed that the peak discharge was reduced up to 24% relative to impervious brown roof. The results show an increment of pH and high concentration of phosphate for the runoff generated from the green roof and the runoff water quality ranged between class I and II under INWQS.

This report published by the Swiss Federal Office of Energy (SFOE) presents the results of a study made on possible methods that could be used for the implementation of a certification system that would provide information on the energy consumption of Swiss buildings. The report examines such systems in use in Austria, Germany and Denmark. Three possible strategies on the implementation of a labelling system for Switzerland are examined. These include a legislation-based system, a private, voluntary, system and the combination of these two approaches. The strategies are examined from the political and legislation points of view.

Full Text Available Designers and clients alike are now emphasising on how to make their buildings green. Currently a lot of green councils worldwide are dealing with innovative ways to implement energy efficient new buildings. They have adopted various criteria and rating systems in an endeavour to classify buildings that contribute to environment sustainability, efficiency and users health. The aim of the paper is to present an overview of the criteria adopted by selected green building councils. This paper discusses five of the rating systems available in terms of their similarities and differences and proposes a new framework based on the project life cycle for the development of the green building criteria. Criteria during the construction phase of the building is certainly lacking such as pollution control in terms of CO2 emission, dust, and other pollutants.

Power generation from thermoelectric system-embedded Plexiglas for green building technology

KAUST Repository

Inayat, Salman Bin

2012-06-09

Thermoelectric materials embedded through or inside exterior glass windows can act as a viable source of supplemental power in geographic locations where hot weather dominates. This thermoelectricity is generated because of the thermal difference between the high temperature outside and the relatively cold temperature inside. Using physical vapor deposition process, we experimentally verify this concept by embedding bismuth telluride and antimony telluride through the 5 mm Plexiglas to demonstrate 10 nW of thermopower generation with a temperature gradient of 21 °C. Albeit tiny at this point with non-optimized design and development, this concept can be extended for relatively large-scale power generation as an additional power supply for green building technology.

A theoretical study to asses the influence of banking and borrowing under various penalty systems for tradable green certificates (TGC) is described. It was shown that at least in theory, TGC systems can be an effective and efficient means of encouraging the use of renewables. The study focused on market dynamics in situations where the obligatory demand of the market must deal with fines for non-compliance. The laboratory experiment is described in detail and flow diagrams are shown. The author claims that experiments of this type can add to the understanding of environmental and market dynamics. A list of policy implications and recommendations is given

Full Text Available There have been much interest and many efforts to control global warming and reduce greenhouse gas (GHG emissions throughout the world. Recently, the Republic of Korea has also increased its GHG reduction goal and searched for an implementation plan. In buildings, for example, there have been technology developments and deployment policies to reduce GHG emissions from a life cycle perspective, covering construction materials, building construction, use of buildings and waste disposal. In particular, Korea’s Green Standard for Energy and Environmental Design is a certification of environmentally-friendly buildings for their energy saving and reduction of environmental pollution throughout their lives. In fact, the demand and adoption of the certification are rising every year. In construction materials and buildings, as a result, an environmentally-friendly aspect has become crucial. The importance of construction material and building development technologies that can reduce environmental load by diminishing GHG emissions in buildings has emerged. Moreover, there has been a rising necessity to verify the GHG reduction effects of buildings. To assess the reduction of carbon emissions in the buildings built with low-carbon construction technologies and materials, therefore, this study estimated life cycle carbon emissions in reference buildings in which general construction materials are used and in low-carbon buildings. For this, the carbon emissions and their reduction from construction materials (especially concrete between conventional products and low-carbon materials were estimated, using Life Cycle Assessment (LCA. After estimating carbon emissions from a building life cycle perspective, their reduction in low-carbon buildings compared to the reference buildings was reviewed. The results found that compared to conventional buildings, low-carbon buildings revealed a 25% decrease in carbon emissions in terms of the reduction of Life Cycle
