3 Materials in Construction The issues remain the same Materials Use Buildings use 40% of global raw materials (3B tons/yr) Waste 36M tons/yr of building related construction and demolition debris is generated in the U.S. LEED (MR) has focused on choosing materials with sustainable attributes: But the focus of LEED v4 moves to Transparency (Disclosure and Optimization) in Material Reporting and Life Cycle Impacts Recycled, Reused, Reclaimed, Rapidly Renewable, Sustainably Harvested Source: Lenssen and Roodman (1995).

4 LEED V4 MR Changes In a Nutshell The benefits of recycling old tires are obvious. It saves energy. It avoids new or additional toxic manufacturing inputs. Recycling also forestalls landfilling tire waste. Tire dumps pollute groundwater and can catch fire and smolder for months or even years. But there is a flip side to this equation that has, to date, been poorly considered: tires contain a host of toxic ingredients to which people may be exposed when this material is brought into homes, schools, gyms and offices.* Old Rating Systems Reward Single Attribute Recycled New Systems take a Look at the Product over it s Lifetime *Healthy Building Network, Avoiding Contaminants in Tire-Derived Flooring, Vallette,Jim Copyright 2013, CaraGreen, Carrboro, North Carolina 4

18 Disclosure Environmental Product Declarations: An environmental product declaration (EPD) is a statement of a product s ingredients and environmental impacts across its lifecycle. In the same way that nutritional labels help consumers compare the health benefits of food items, an EPD enables them to compare the environmental impacts of products. An EPD is not another eco label. It is a statement of fact about the environmental impacts of a product. There are no ratings, claims or judgement calls to be made, as there are with eco labels: an EPD itself doesn t tell you whether a product is good or bad, green or polluting; it just provides the facts to enable better informed decisions.

21 Are the sustainable materials we use today going to meet the requirements put in place for the future. They Can. We Need to Help. Manufacturers need to work together to build the infrastructure: LEED requires information and then better choices Architects and Designers need to push manufacturers to comply Critical mass will drive adoption Copyright 2013, CaraGreen, Carrboro, North Carolina 21

22 Summary LEED Materials and Resources Credits have changed The intent is more disclosure, more transparency A side effect is more complicated documentation and understanding There is a need for education which will lead to adoption of standards and best practices Copyright 2013, CaraGreen, Carrboro, North Carolina 22
