•Green Building - What and Why?
•U.S. Green Building Council
•LEED™ Certification Background
•A look at the process with the help of case studies:
Bren Hall

Sundeck Restaurant
What is Green Building?
•No set definition or rules
•General themes
•Use recycled & recyclable resources
•Use water, energy, lumber, and other resources
efficiently
•Localize resource inputs
•Eliminate toxins
•Protect & restore nature
•Improve Quality
•Conserve resources
Why Build Green?
•Decreased energy and water consumption
•Increased health and productivity of workers
•Expedited government approval processes
•Decreased waste disposal costs
•Creation of a more durable and long lasting building
•Increased sales value of the property
•Oh yeah, it is good for the environment, too

The U.S. Green Building
Council
•A non-profit 275 member consensus coalition formed in 1993
•Mission: “to accelerate the adoption of green building
practices, technologies, policies, and standards”
•Committee-Based: provides a forum for members to resolve
differences, build alliances, and forge cooperative solutions
•Member-Driven: targets issues identified by the members as
the highest priority

Leadership in Energy and Environmental Design
•Voluntary, consensus-based, market-driven rating
building rating system
•Evaluates environmental performance from a “whole
building” perspective over a building’s life cycle
•Intended to be a definitive standard for what constitutes
a green building
•Based on accepted energy and environmental principles
•Attempts to strike a balance between known effective
practices and emerging concepts
•Still in pilot and revision phase
Leadership in Energy and Environmental Design
•Eligibility: All commercial buildings, as defined by standard
building codes
•Feature-oriented system where credits are earned for
satisfying each criteria
