Green building is the practice of increasing the efficiency with which buildings use resources — energy, water, and materials — while reducing building impacts on human health and the environment during the building's lifecycle, through better siting, design, construction, operation, maintenance, and removal.Frej, Anne B., editor. "Green Office Buildings: A Practical Guide to Development". Washington, D.C.: ULI--The Urban Land Institute, 2005. Pp 4-8]

Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

*Efficiently using energy, water, and other resources
*Protecting occupant health and improving employee productivity
*Reducing waste, pollution and environmental degradation [ [ Basic Information | Green Building |US EPA] ]

A similar concept is natural building, which is usually on a smaller scale and tends to focus on the use of natural materials that are available locally. [Hopkins, R. 2002. [ "A Natural Way of Building."] Transition Culture. Retrieved: 2007-03-30.] Other commonly used terms include sustainable design and green architecture.

The related concepts of sustainable development and sustainability are integral to green building. Effective green building can lead to 1) "reduced operating costs" by increasing productivity and using less energy and water, 2) "improved public and occupant health" due to improved indoor air quality, and 3) "reduced environmental impacts" by, for example, lessening storm water runoff and the heat island effect. Practitioners of green building often seek to achieve not only ecological but aesthetic harmony between a structure and its surrounding natural and built environment, although the appearance and style of sustainable buildings is not necessarily distinguishable from their less sustainable counterparts.

Environmental impact

Green building practices aim to reduce the environmental impact of buildings. Buildings account for a large amount of land use, energy and water consumption, and air and atmosphere alteration. In the United States, more than convert|2000000|acre|km2 of open space, wildlife habitat, and wetlands are developed each year.

As of 2006, buildings used 40 percent of the total energy consumed in both the US and European Union. [Baden, S., et al., [ "Hurdling Financial Barriers to Lower Energy Buildings: Experiences from the USA and Europe on Financial Incentives and Monetizing Building Energy Savings in Private Investment Decisions."] "Proceedings of 2006 ACEEE Summer Study on Energy Efficiency in Buildings," American Council for an Energy Efficient Economy, Washington DC, August 2006. ] [US Department of Energy. [ "Annual Energy Review 2006"] 27 June 2007. Accessed 27 April 2008.] In the US, 54 percent of that percentage was consumed by residential buildings and 46 percent by commercial buildings. [Energy Information Administration. US Department of Energy. [ "Energy Consumption by Sector."] 2007. Accessed on: 16 July 2008.] In 2002, buildings used approximately 68 percent of the total electricity consumed in the United States with 51 percent for residential use and 49 percent for commercial use. 38 percent of the total amount of carbon dioxide in the United States can be attributed to buildings, 21 percent from homes and 17.5 percent from commercial uses. Buildings account for 12.2 percent of the total amount of water consumed per day in the United States.Fact|date=July 2008

Considering these statistics, reducing the amount of natural resources buildings consume and the amount of pollution given off is seen as crucial for future sustainability, according to EPA. [Environmental Protection Agency Green Building Workgroup, Building and the Environment: A Statistical Summary, December 2004, [] Retrieved: 2008-04-29.]

The environmental impact of buildings is often underestimated, while the perceived costs of green buildings are overestimated. A recent survey by the World Business Council for Sustainable Development finds that green costs are overestimated by 300 percent, as key players in real estate and construction estimate the additional cost at 17 percent above conventional construction, more than triple the true average cost difference of about 5 percent. [World Business Council for Sustainable Development, August 2007, [ "Energy Efficiency in Buildings: Business Realities and Opportunities"] Retrieved: 2007-09-05.]

Green building practices

Green building brings together a vast array of practices and techniques to reduce and ultimately eliminate the impacts of buildings on the environment and human health. It often emphasizes taking advantage of renewable resources, e.g., using sunlight through passive solar, active solar, and photovoltaic techniques and using plants and trees through green roofs, rain gardens, and for reduction of rainwater run-off. Many other techniques, such as using packed gravel for parking lots instead of concrete or asphalt to enhance replenishment of ground water, are used as well. Effective green buildings are more than just a random collection of environmental friendly technologies, however. [Hal Levin, 1996. [ BEST SUSTAINABLE INDOOR AIR QUALITY PRACTICES IN COMMERCIAL BUILDINGS] ] They require careful, systemic attention to the full life cycle impacts of the resources embodied in the building and to the resource consumption and pollution emissions over the building's complete life cycle.

On the aesthetic side of green architecture or sustainable design is the philosophy of designing a building that is in harmony with the natural features and resources surrounding the site. There are several key steps in designing sustainable buildings: specify 'green' building materials from local sources, reduce loads, optimize systems, and generate on-site renewable energy.

Green building materials

Building materials typically considered to be 'green' include rapidly renewable plant materials like bamboo and straw, lumber from forests certified to be sustainably managed, dimension stone, recycled stone, recycled metal, and other products that are non-toxic, reusable, renewable, and/or recyclable (eg Trass, Linoleum, sheep wool, panels made from paper flakes,compressed earth block, adobe, baked earth, rammed earth, clay, vermiculite, flax linen, sisal, seagrass, cork, expanded clay grains, coconut, wood fibre plates, calcium sand stone... [Duurzaam en Gezond Bouwen en Wonen by Hugo Vanderstadt] ). Building materials should be extracted and manufactured locally to the building site to minimize the energy embedded in their transportation.

Reduced Energy Use

Green buildings often include measures to reduce energy use. To increase the efficiency of the building envelope, (the barrier between conditioned and unconditioned space), they may use high-efficiency windows and insulation in walls, ceilings, and floors. Another strategy, passive solar building design, is often implemented in low-energy homes. Designers orient windows and walls and place awnings, porches, and trees [Simpson, J.R. Energy and Buildings, Improved Estimates of tree-shade effects on residential energy use, February 2002. [] Retrieved:2008-04-30.] to shade windows and roofs during the summer while maximizing solar gain in the winter. In addition, effective window placement (daylighting) can provide more natural light and lessen the need for electric lighting during the day. Solar water heating further reduces energy loads.

Finally, onsite generation of renewable energy through solar power, wind power, hydro power, or biomass can significantly reduce the environmental impact of the building. Power generation is generally the most expensive feature to add to a building.

Reduced Waste

Green architecture also seeks to reduce waste of energy, water and materials. During the construction phase, one goal should be to reduce the amount of material going to landfills. Well-designed buildings also help reduce the amount of waste generated by the occupants as well, by providing on-site solutions such as compost bins to reduce matter going to landfills.

To reduce the impact on wells or water treatment plants, several options exist. "Greywater", wastewater from sources such as dishwashing or washing machines, can be used for subsurface irrigation, or if treated, for non-potable purposes, e.g., to flush toilets and wash cars. Rainwater collectors are used for similar purposes.

Centralized wastewater treatment systems can be costly and use a lot of energy. An alternative to this process is converting waste and wastewater into fertilizer, which avoids these costs and shows other benefits. By collecting human waste at the source and running it to a semi-centralized biogas plant with other biological waste, liquid fertilizer can be produced. This concept was demonstrated by a settlement in Lubeck Germany in the late 1990s. Practices like these provide soil with organic nutrients and create carbon sinks that remove carbon dioxide from the atmosphere, offsetting greenhouse gas emission. Producing artificial fertilizer is also more costly in energy than this process. [Lange, Jorg; Grottker, Mathias; Otterpohl, Ralf. Water Science and Technology, Sustainable Water and Waste Management In Urban Areas, June 1998. [] Retrieved:April 30, 2008.]

International frameworks and assessment tools

IPCC Fourth Assessment Report []

Climate Change 2007, the Fourth Assessment Report (AR4) of the United Nations Intergovernmental Panel on Climate Change (IPCC), is the fourth in a series of such reports. The IPCC was established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess scientific, technical and socio-economic information concerning climate change, its potential effects and options for adaptation and mitigation.

UNEP and Climate change []

UNEP works to facilitate the transition to low-carbon societies, support climate proofing efforts, improve understanding of climate change science, and raise public awareness about this global challenge.

GHG Indicator []

The GHG Indicator: UNEP Guidelines for Calculating Greenhouse Gas Emissions for Businesses and Non-Commercial Organizations

Agenda 21 []

Agenda 21 is a programme run by the United Nations (UN) related to sustainable development. It is a comprehensive blueprint of action to be taken globally, nationally and locally by organizations of the UN, governments, and major groups in every area in which humans impact on the environment. The number 21 refers to the 21st century.


FIDIC’s Project Sustainability Management Guidelines were created in order to assist project engineers and other stakeholders in setting sustainable development goals for their projects that are recognized and accepted by as being in the interests of society as a whole. The process is also intended to allow the alignment of project goals with local conditions and priorities and to assist those involved in managing projects to measure and verify their progress.

The PSM Guidelines are structured with Themes and Sub-Themes under the three main sustainability headings of Social, Environmental and Economic. For each individual Sub-Theme a core project indicator is defined along with guidance as to the relevance of that issue in the context of an individual project.

iiSBE's SBtool []

SBTool, formerly known as GBTool, is designed to assess the environmental and sustainability performance of buildings.SBTool is the software implementation of the Green Building Challenge (GBC) assessment method that has been under development since 1996 by a group of more than a dozen teams. The GBC process was launched by Natural Resources Canada, but responsibility was handed over to the International Initiative for a Sustainable Built Environment (iiSBE) in 2002.

Sustainable Building Alliance []

The SBA is a non-profit, non-partisan international network of universities, research centers and technical assessment organizations that is intended to accelerate the international adoption of Sustainable Building (SB) practices through the promotion of shared methods of building performance assessment and rating. The SBA initiative is supported by the UNESCO Chair for sustainable buildings and the UNEP sustainable building and construction initiative.

Overview of other assessment tools and frameworks


CEEQUAL, the Civil Engineering Environmental Quality and Award Scheme, is an assessment and awards scheme for improving sustainability in civil engineering and public realm projects. Its objective is to encourage the attainment of environmental excellence in civil engineering, and thus to deliver improved environmental and social performance in project specification, design and construction.

The system uses a points-scoring-based assessment, which is applicable to any civil engineering or public realm project and includes environmental and social aspects such as the use of water, energy and land, impacts on ecology, landscape, neighbours, archaeology, as well as waste minimisation and management, and community relations and amenity. Awards are made to projects in which the clients, designers and constructors have gone beyond the legal and environmental minima, to achieve distinctive environmental standards of performance.

Assessments are carried out by trained assessors who are responsible for scoping the credit issues to be addressed (in consultation with the CEEQUAL verifier). The assessor then completes the assessment and submits it to the verifier for review and approval. Once the verifier is satisfied with the assessment the CEEQUAL certificate is issued.

EN 15804 (CEN TC350)

The development of EN15804 Sustainability of construction works is currently underway with the majority of sections under development but some under approval. This standard is intended to set out a methodology for the assessment of the sustainability of materials, buildings and construction projects using the Life Cycle Assessment approach.

*Environmental product declarations - Product category rules

*Environmental product declarations - Communication formats

*Environmental product declarations - Methodology and data for generic data

*Description of the building life cycle

*Assessment of environmental performance of buildings - Calculation methods

*Integrated assessment of building performance - Part 1: General framework

*Integrated assessment of building performance - Part 2: Framework for the assessment of environmental performance

*Integrated assessment of building performance - Part 3: Framework for the assessment of social performance

*Integrated assessment of building performance - Part 4: Framework for the assessment of economic performance

The development of the standard is due to be completed by the end of 2011.

Global Reporting Initiative

The Global Reporting Initiative's aim is to make the reporting on economic, environmental, and social performance by all organizations is as routine and comparable as financial reporting.

The Sustainability Reporting Framework provides guidance for organizations to use as the basis for disclosure about their sustainability performance, and also provides stakeholders a universally- applicable, comparable framework in which to understand disclosed information.

The Reporting Framework contains the core product of the Sustainability Reporting Guidelines, as well as Protocols and Sector Supplements. The Guidelines are used as the basis for all reporting. They are the foundation upon which all other reporting guidance is based, and outline core content for reporting that is broadly relevant to all organizations regardless of size, sector, or location. The Guidelines contain principles and guidance as well as standard disclosures – including indicators – to outline a disclosure framework that organizations can voluntarily, flexibly, and incrementally, adopt.

Protocols underpin each indicator in the Guidelines and include definitions for key terms in the indicator, compilation methodologies, intended scope of the indicator, and other technical references.

Sector Supplements respond to the limits of a one-size-fits-all approach. Sector Supplements complement the use of the core Guidelines by capturing the unique set of sustainability issues faced by different sectors such as mining, automotive, banking, public agencies and others.

IPD Environment Code

The IPD Environment Code was launched in February 2008. The Code is intended as a good practice global standard for measuring the environmental performance of corporate buildings. Its aim is to accurately measure and manage the environmental impacts of corporate buildings and enable property executives to generate high quality, comparable performance information about their buildings anywhere in the world. The Code covers a wide range of building types (from offices to airports) and aims to inform and support the following;

*Creating an environmental strategy

*Inputting to real estate strategy

*Communicating a commitment to environmental improvement

*Creating performance targets

*Environmental improvement plans

*Performance assessment and measurement

*Life cycle assessments

*Acquisition and disposal of buildings

*Supplier management

*Information systems and data population

*Compliance with regulations

*Team and personal objectives

IPD estimate that it will take approximately three years to gather significant data to develop a robust set of baseline data that could be used across a typical corporate estate.

ISO 21931

ISO/TS 21931:2006, Sustainability in building construction -- Framework for methods of assessment for environmental performance of construction works -- Part 1: Buildings, is intended to provide a general framework for improving the quality and comparability of methods for assessing the environmental performance of buildings. It identifies and describes issues to be taken into account when using methods for the assessment of environmental performance for new or existing building properties in the design, construction, operation, refurbishment and deconstruction stages. It is not an assessment system in itself but is intended be used in conjunction with, and following the principles set out in, the ISO 14000 series of standards.

Regulatory instruments, R&D, financial and policy processes & examples in some countries

It is impossible to list in an exhaustive manner the existing plethora of public, private (or both) initiatives at national and international level. An existing instrument design by the OECD/IEA and UNEP gives to the public an accurate vision of the policies implemented in various countries.

A general conclusion when browsing the literature is that there is a tangible increase in the number of policies and instruments either in the process of design or currently in force.


There is a system in place in Australia called First Rate designed to increase energy efficiency of residential buildings. The Green Building Council of Australia (GBCA) has developed a green building standard known as Green Star. [ [ Green Building Council Of Australia] ]

In Adelaide, South Australia, there are at least three different projects that incorporate the principles of Green building. The Eco-City development is located in Adelaide's city centre, the Aldinga Arts Eco Village is located in Aldinga and Lochiel Park is located at Campbelltown. Guidelines for building developments in each project are outlined in the bylaws. The bylaws include various permutations of grey water reuse, reuse of stormwater, capture of rainwater, use of solar panels for electricity and hotwater, solar passive building design and community gardens and landscaping. Other developments such as Mawson Lakes and the 'Lightsview' development near Northgate, both to the north of the Adelaide CBD, also have green building requirements.

Melbourne has a rapidly growing environmental consciousness, many government subsidies and rebates are available for water tanks, water efficient products (such as shower heads) and solar hot water systems. The city is home to many examples of green buildings and sustainable development such as the CERES Environmental Park. [ [ CERES EcoHouse] ,] Another one is EcoLinc in Bacchus Marsh. Two of the most prominent examples of green commercial buildings in Australia are located in Melbourne — 60L [ [ 60L green building] ,] and Council House 2 (also known as CH2). [ [ CH2 building] ,]

In Perth, Western Australia, there are at least three different projects that incorporate the principles of Green building. The Office development located in Murray Street, West Perth being designed by Eco Design Consultant in collaboration with Troppo Architects is one of them. The other two are mixed develpment along Wellington Street, in the ctiy centre. Guidelines for building developments in each project are outlined in the bylaws and the Green Building Council Australia. The Green Star considerations include Management- Indoor Environment Quality- Energy- Transport- Water- Materials- Land Use & Ecology- Emissions- InnovationFor more information, refer to the Green Building Council Australia.

The most recent building to receive the 6 Green Star award was in Canberra, where Australian Ethical Investment Ltd [ [ Australian Ethical Investment Ltd] ] refurbished an existing office space in Trevor Pearcey House. The total cost of the renovation was $1.7 million, and produced an estimated 75% reductions in carbon dioxide emissions, 75% reduction in water usage, and used over 80% recycled materials. The architects were Collard Clarke Jackson Canberra, architectural work done by Kevin Miller, interior design by Katy Mutton. [ [ Collard Clarke Jackson Canberra] ]

In NSW, an on-line assessment system called BASIX (Building Sustainability Index) ( requires that all new residential developments to reduce water consumption by 40%, and CO2 emissions by 40% for detached dwellings and between 20 and 30% for multi unit dwellings compared to an average baseline. The online system provides designers with a mathematical model of the development that considered the interactions between the energy and water systems of the whole, drawing on climatic and normalised rainfall data for individual locations.


Canada has implemented "R-2000" guidelines for new buildings built after the year 2000. Incentives are offered to builders to meet the R-2000 standard in an effort to increase energy efficiency and promote sustainability.

A progression of the R-2000 home program is the EnerGuide for New Houses service. This service is available across Canada and is designed to allow home builders and home buyers to build homes that use significantly less energy than the average homes being built. Some Canadian provinces are considering mandatory use of the service for all new homes.

In December 2002, Canada formed the Canada Green Building Council and in July 2003 obtained an exclusive licence from the US Green Building Council to adapt the LEED rating system to Canadian circumstances. The path for LEED's entry to Canada had already been prepared by BREEAM-Canada, an environmental performance assessment standard released by the Canadian Standards Association in June 1996. The American authors of LEED-NC 1.0 had borrowed heavily from BREEAM-Canada in the outline of their rating system; and in the assignment of credits for performance criteria.

In March 2006, Canada's first green building point of service, [ Light House Sustainable Building Centre] , opened on Granville Island in the heart of Vancouver, BC. A destination for the public and professionals alike, the Light House resource centre is funded by Canadian government departments and businesses to help implement green building practices and to recognize the economic value of green building as a new regional economy.

* Beamish-Munro Hall at Queen's University features sustainable construction methods such as high fly-ash concrete, triple-glazed windows, dimmable fluorescent lights and a grid-tied photovoltaic array.
* [ Gene H. Kruger Pavilion] at Laval University uses largely non polluting, non toxic, recycled and renewable materials as well as advanced bioclimatic concepts that reduce energy consumption by 25% compared with a concrete building of the same dimensions. The structure of the building is made entirely out of wood products, thus further reducing the environmental impact of the building.

In July 2007, the French government established six working groups to address ways to redefine France's environment policy. The proposed recommendations were then put to public consultation, leading to a set of recommendations released at the end of October 2007. These recommendations will be put to the French parliament in early 2008.

The name of the process, "Le Grenelle de l'Environnement", refers to a 1968 conference when government negotiated with unions to end weeks of social unrest.

The six working groups addressed climate change, biodiversity and natural resources, health and the environment, production and consumption, democracy and governance, and competitiveness and employment.

Recommendations include:

- invest Eur 1 billion in clean energy over the next four years as part of wide-reaching environmental plan to cut emissions of greenhouse gases, including proposals for ecological taxes;20% reduction in France's energy consumption by 2020 and a boosting of the use of renewable energy, such as wind power and biofuels, by 20% by 2020;- freight be transported on new high-speed rail lines and waterways rather than highways; and- a series of green taxes including a tax on the most polluting vehicles, as well as a tax on transport trucks crossing France's borders.

Building labels

The french regulation (RT) for new construction was following an incremental logic with a regular (every five years) increase in the exigence level requested to achieve by 2020 (RT 2020) a 40% reduction of energy consumption with respect to the RT 2000. Current label are: THPE 2005=20% better than the RT2005. THPE EnR 2005= 30% better than RT2005+ Renewable energy production for the majority of heating. Within the framework of the “Grenelle de l’envronnement”, a performance acceleration is expected to meet with the following objectives for tertiary buildings:

I. Low consumption buildings (BBC) by 2010 with minimum requirements concerning the levels of renewable energy and CO2 absorption materials by 2012.

II. Passive new buildings (BEPAS) or Positive buildings (BEPOS) by 2020.

Labels for refurbishment of existing BBC buildings.

All these developments match with the european and international regulations and frameworks.


German developments that employ green building techniques include:
*The Solarsiedlung (Solar Village) in Freiburg, Germany, which features energy-plus houses.
*The Vauban development, also in Freiburg.
*Houses designed by Baufritz, incorporating passive solar design, heavily insulated walls, triple-glaze doors and windows, non-toxic paints and finishes, summer shading, heat recovery ventilation, and greywater treatment systems.

New Zealand

The New Zealand Green Building Council has been in formation since July 2005. An establishment board was formed later in 2005 and with formal organisational status granted on 1st February 2006. That month Jane Henley was appointed as the CEO and activity to gain membership of the World GBC began. In July 2006 the first full board was appointed with 12 members reflecting wide industry involvement. The several major milestones were achieved in 2006/2007; becoming a member of the World GBC, the launch of the Green Star NZ — Office Design Tool, and welcoming our member companies.

South Africa

The Green Building Council of South Africa (launched 2008) has developed a Green Star SA rating tools, based on the [ Green Building Council Of Australia] tools, to provide the property industry with an objective measurement for green buildings and to recognize and reward environmental leadership in the property industry. Each Green Star SA rating tool reflects a different market sector (eg. office, retail, multi-unit residential, etc.).

The first tool being developed is Green Star SA-Office which was published in pilot form for public comment in July 2008, with final release at the Green Building Council of South Africa Convention & Exhibition ’08 on 2-4 November 2008.

South Africa is in the process of incorporating an energy standard [ SANS 204] which aims to provide energy-saving practices as a basic standard in the South African context.

Green Building Media (launched 2007) has also played an instrumental role in green building in South Africa, through their informational portal, [] , as well as their monthly Green Building e-Journal of South Africa, which is sent to professionals within the built environment. They currently hold two annual events which focusing on sustainability; the Green Building Conference and a Retrofitting Seminar.

United Kingdom

:Main|Energy efficiency in British housing

The Association for Environment Conscious Building (AECB) has promoted sustainable building in the UK since 1989.

The UK Building Regulations set requirements for insulation levels and other aspects of sustainability in building construction.

In Wales, advice on and access to sustainable building is available from a not-for-profit organisation called Rounded Developments Enterprises [] . They run a Sustainable Building Centre in Cardiff.

One of the best known green buildings in the UK is the Media Centres' Friendly Street Building []

United States

The United States has established several sustainable design organizations and programs.

The U.S. Green Building Council (USGBC) is a non-profit trade organization that promotes sustainability in how buildings are designed, built and operated. The USGBC is best known for the development of the Leadership in Energy and Environmental Design (LEED) rating system and Greenbuild, a green building conference that promotes the green building industry. As of September 2008, USGBC has more than 17,000 member organizations from every sector of the building industry and works to promote buildings that are environmentally responsible, profitable and healthy places to live and work. To achieve this it has developed a variety of programs and services, and works closely with key industry and research organizations and federal, state and local government agencies. USGBC also offers a host of educational opportunities, including workshops and Web-based seminars to educate the public and industry professionals on different elements of the green building industry, from the basics to more technical information. Through its Green Building Certification Institute, USGBC offers industry professionals the chance to develop expertise in the field of green building and to receive accreditation as green building professionals.

The National Association of Home Builders, a trade association representing home builders, remodelers and suppliers to the industry, has created a voluntary residential green building program known as NAHBGreen ( The program includes an online scoring tool, national certification, industry education, and training for local verifiers. The online scoring tool is free to builders and to homeowners.

The Green Building Initiative is a non-profit network of building industry leaders working to mainstream building approaches that are environmentally progressive, but also practical and affordable for builders to implement. The GBI has developed a web-based rating tool called Green Globes, which is being upgraded in accordance with ANSI procedures.

The United States Environmental Protection Agency's Energy Star program rates commercial buildings for energy efficiency and provides Energy Star qualifications for new homes that meet its standards for energy efficient building design.

In 2005, Washington State became the first state in the United States to enact green building legislation. [ [ Washington State Law Mandates Green Building] , RenewableEnergyAccess, 2005-04-21. Retrieved 2007-02-10] According to the law, all major public agency facilities with a floor area exceeding 5,000 square feet (465 m²), including state funded school buildings, are required to meet or exceed LEED standards in construction or renovation. The projected benefits from this law are 20% annual savings in energy and water costs, 38% reduction in waste water production and 22% reduction in construction waste.

Charlottesville, Virginia became one of the first small towns in the United States to enact green building legislation. [ [ Albemarle examines cost, benefits of green buildings] , Charlottesville Tomorrow, 2007-04-20.
