What They Are For architects and interior designers wanting to learn about various aspects of a product's performance, using only one tool, Environmental Product Declarations (EPDs) will be useful. As International Standards Organization (ISO) Type 3 EcoLabels, EPDs must be based on a product Life Cycle Assessment (LCA), though other types of qualitative and quantitative product information may be included. Many countries in the European Union have been developing EPDs during the past decade. As of early 2007, there is an ISO Standard 14025 in place encouraging development of EPDs in: Sweden, Norway, Denmark, Finland, Germany, Italy and the Netherlands. Additionally, Japan has played a key role in advancing the understanding and use of EPDs. For products to be sold within the European Union, there is now a mandate that they must carry an ISO-compliant EPD (CEN 350) beginning in 2009. As a result, the European Union Committee on the Environment is taking a leadership role in shaping a Global Product Information System, featuring EPDs. As the data used for modeling the building's full life-cycle has to be credible, consistent and transparent, it is best drawn from ISO-compliant product LCAs. The starting point for high quality and reliable data in LCAs is Product Criteria Rules (PCRs). All performance data included in an EPD must bear the signature of a third-party organization and individual reviewer to meet the ISO Standard for EPDs. EPDs feature a broad range of product performance information presented in a visually engaging format, including: How They're Used Who's Developing EPDs The European Union is quickly catching up, with EPD programs now in place in Germany (3,650 products); the Nordic countries (1,500); Spain (1,170); The Netherlands (370); and Austria. In China and India, EPD programs are in the early stages of development. In the United States, the organization poised to play a leadership role in the development and use of EPDs is TheGreenStandard.org-formerly known as the International Design Center for the Environment (IDCE). The organization has developed The Green Standard Manufacturer's Wizard to assist manufacturing firms in creating an efficient way to collect and analyze product data to create a full LCA for use in several formats. The first tool will be a simple EcoLabel based on the product LCA results. The second is a multi-performance product profile in an EPD that meets ISO Standard 14025. While the first will provide a science-based evaluation of all environmental impacts of a product throughout its full life-cycle, the second will offer many types of product performances: environmental, mechanical, safety, etc. Both will be available in the fall of 2007. GEDnet, an international not-for-profit headquartered in Sweden, has played a key role in supporting the development and use of EPDs around the world by manufacturers in many sectors through providing certification and posting of those meeting the ISO Standard. GEDnet is leading the initiative to make EPDs a centerpiece of the emerging Global Product Information System. Development of EPDs for many products will advance the use of common language and common metrics for product design and selection, meeting the demands from the A&D community to have tools enabling them to be contributors to a sustainable world.
What They Do
The ISO has encouraged the development of EPDs as instruments to support sustainable building policies in the design and construction sectors. The primary purpose of building product EPDs is to illustrate the environmental performance of a building-as derived from its many parts and selected products.
Architects, interior designers and other building team members could make good use of EPDs in the following ways:
Japan is the leading country worldwide in the development of EPDs, having initiated a program in 1996 that is managed by the Japan Environmental Management Association for Industry (JEMAI). Called the EcoLeaf, this program of EPDs now includes more than 5,000 brand products from 47 product groups.
What They Contribute
All stakeholders involved-owners, designers, contractors, interior designers, facility managers and the individuals who work or live in these sustainably developed buildings-benefit from improved human health, higher productivity, and lower costs and impacts. In summary, EPDs encompass multiple features. They are:
