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

4
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

  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
