Eco Design Life Cycle Stages &Typical Impacts Product Lifecycle Impact Tool Opportunities Business Benefits EDECON • Eco Design for the Construction Industry Why the Construction Industry? 26 million 50% 35% Policy Trends & Issues • Policy Measures supporting Europe 2020 • COM(2011) 21 A resource-efficient Europe • COM(2011) 571 - The Roadmap to a Resource Efficient Europe • COM/2013/0196 - Communication on Building the Single Market for Green Products • puts forward two methods to measure environmental performance throughout the lifecycle, the Product Environmental Footprint (PEF) and the Organisation Environmental Footprint (OEF) • Rec 2013/179/EU - Commission Recommendation of 9 April 2013 on the use of common methods to measure and communicate the life cycle environmental performance of products and organisations Change in emphasis from energy to resource efficiency and wider life cycle considerations Environmental legislation in C&D Sector • Regulation No 305-2011 on the Marketing of Construction Products • Directive 2001/925/EC on Eco-design of Energy Related Products • Energy Performance of Buildings Directive 2010/31/EU(Recast) • Waste Framework Directive (2008/98/EC) Why is Eco Design so Important?

Opportunities – Design For Use • Reduce energy & water requirements, consider renewable sources of energy • Reduce requirement for consumables • Maximise product lifetime - durable, reliable, easy to maintain, repair & upgrade • Reduce emissions to air, water and soil during use • Educate user on efficient operation of equipment • Consider other complementary functions • Consider providing additional services • Consider selling a service rather than a product Opportunities – Design For Use Opportunities – Design For End of 1st Life • Restrict use of substances classified as hazardous • Make it easy to dismantle to enable reuse, disassembly and recycling • Mark all materials using internationally recognised codes, especially polymers and other recyclable materials • Avoid aspects detrimental to reuse and recycling e.g. mixtures of materials • Educate user on correct disposal of equipment • Consider take-back systems (reduce raw material costs) Anglian Windows Tackles raw materials shortage by creating new carpet tiles from old Business Benefits of Eco Design Thank you
