The use of EPD for Buildings LCAs

• Environmental Production

Declaration (EPD) : EN 15804+A1

• From Cradle to Grave

• Produced by the industry

• Available on databases, e.g. :

www.inies.com

• When comparing EPD, check for :

▪ System boundary

▪ Functional unit

▪ Technical characteristics

In conclusion

• Explore different possibilities to optimize sustainable performance of buildings

• Availability (the more there is the better it is), transparency, quality of EPDs are essential

• Organize data-exchange between manufacturers, designers, builders and applications (tools,

databases, etc.)

• Tools with BIM are actually developped to help teams at early stages of design
