What purpose do environmental product declarations serve?
- Environmental Product Declarations (EPD) form the basis for the data for assessing buildings on an ecological level. This is currently laid down in the new European Standards project "Sustainability of buildings".
- Environmental Product Declarations are based on ISO standards and are therefore internationally aligned. They are suitable as proof of environmental claims in the public procurement arena.
- Environmental Product Declarations offer the relevant basic data on environmental properties of a product for sales and marketing purposes.
Environmental Product Declarations (EPD)
Most buildings are assigned to the building in one "system". A Type-III declaration for building products which also helps to assess the entire building, thus lent itself to being created. Resource consumption and environmental emissions are recorded throughout the entire manufacturing process. The resulting contribution to the greenhouse effect, or eutrophication or acidification of water can be quantified and assessed using Lifecycle Assessment methodology. Lifecyle Assessments also provide a systematic and standardised basis for data in order to create an ecological assessment of a building in the "modular construction system" from declarations on individual building products. In a lifecylce analysis, the entire life of the building, the building phase with possible conversions as well as demolition and disposal are taken into consideration and the contribution of the building products to energy efficiency or to other aspects of sustainable management of a building are represented.
The declaration includes statements on the use of energy and resources and to what extent a product contributes to the greenhouse effect, acidification, eutrophication, destruction of the ozone layer and smog formation. In addition, details are given about the technical properties which are required for assessing the performance of the building products in the building, like durability, heat and sound insulation or the influence on the quality of the indoor air.
The ISO-Type-III declaration is directed at many target groups in regards to these qualtitative statements about environmental performance of building products: Planners, architects, building companies, real estate companies, facility manager and of course the companies who are involved in manufacturing and serving the supply chain from raw materials to the building itself.
