What is Green Building?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?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

•Creation of a more durable and long lasting building
•Increased sales value of the property
•Oh yeah, it is good for the environment, too
•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
