LEEDs Objectives
Green building addresses two kinds of problems
related to materials and resources:
Waste management
Life-cycle impacts
LEED recognizes and encourages strategies that
consider materials and resources from a long-
term, life-cycle perspective.

Section Concept:
Life cycle
Life cycle assessment
Life cycle example Cradle to Cradle as opposed to Cradle toGrave;
Cradle to Cradle (C2C) is focusing on:
environmentally sensitive product design and
controlling the generation of waste.
The goal is to reuse rather than retire and dispose and it affects
facilities and equipment alike.

Assessment and Measurements
Materials and Resources
The Sustainable Forestry Initiative (SFI) label is a sign you are buying
wood and paper products from a responsible source, backed by a rigorous,
third-party certification audit.
LECTURE 3 12
Best Pract ices = RRR :
Reduce construction waste generation
Reuse existing structures
Recycle construction waste
Select non-toxic, recycled content or rapid
renewable materials
Materials and Resources
Most building materials utilize finite raw resources or resources with long
regeneration cycles.
Utilizing rapidly renewable materials that have less than ten year harvest
periods diminishes the ecological footprint of a building project.

Real life examples:Joe Serna Jr. California EPA Headquarters:
Construction materials salvaged and refurbished
Purchased recycled materials
Used certified-wood base materials FSC wood
Materials and Resources
Forest Stewardship Council (FSC) provides international leadership
system for building wood products in terms of their environmental source
and social responsible management of the world forests.
Recycled content can be:
post-consumer such as waste generated by households
pre-consumer such as material diverted from waste stream
during the manufacturing process

Innovation in design
LEED has recognized the following exemplary
performance strategies above and beyond existing
requirements:
Doubling density requirements for Sustainable Sites
credits.
Significantly reducing indoor water use beyond the 40%
requirement.
Significantly diverting construction waste beyond the
requirement of 75%. Providing more day-lighting than the 75% requirement.
