Find Precasters or Suppliers that provide products, equipment and services to make precast concrete.
In the early 13th century, the king of England proclaimed the first food regulatory law, the Assize of Bread, which prohibited bakers from mixing ground peas and beans into bread dough. Ever since, it has been a cat and mouse game between the food industry and the public. People believed they had a right to know what was in their food so they could make informed decisions on what to buy and consume. Only since May 8th, 1994 have food labels meeting the strict requirements of the Food and Drug Administration been required on all packaged foods.
There was a need for a standardized label format. Otherwise, food companies would divulge nutritional information in different ways that made it difficult for the consumer to make choices.
That is what is now happening in the construction industry. Owners and specifiers are concerned more and more about using sustainable products. It is extremely difficult for them, as it was for grocery shoppers in the 1980’s, to choose the best product. It’s like comparing apples and oranges.
Along comes the environmental product declaration. EPDs as they are more widely known, report environmental impacts such as carbon footprint and others such as acidification or ozone depletion potential. EPDs list quantified life-cycle product data and are owned by the product or brand producer. In essence they are eco-labels and many believe they will be required for all building products in the future.
EPDs are defined by ISO 14025, an international standard for environmental labels and declarations, and are in wider use in other parts of the world (namely Europe) and for a variety of product categories, including structural steel and laminate flooring.
How do you get an EPD for your product? Well first you need an LCA (Life Cycle Assessment) and a PCR (Product Category Rule)
PCR’s govern how LCA’s and EPD’s are written. The PCR is developed for a broad product type such as vinyl siding, asphalt roof shingles, and precast concrete. The industry is working to create a PCR for precast concrete and from that, we can busy on our LCA’s and EPD’s.
These product ecolabel initiatives are still in their infancy, and the NPCA Sustainability Committee and NPCA staff are committed to help you navigate these unfamiliar waters and keep you ahead of emerging trends and regulations. Click Here to see an article on EPD’s, PCR’s and LCA’s.
