Sustainable Buildings and Green Markets

• An Engineering Perspective
• Presented by
• Haven Alford

2
Overview

• Why does it matter
• Elements of Sustainable Buildings
• Government Application (Green Market Incentives)

3
Environmental Impact of Buildings (why does it
matter?)US Commercial Buildings Facts

• 65.2 total US electricity consumption
• gt 36 total US primary energy use
• 30 total US greenhouse gas emissions
• 136 million tons of US
  construction/demolition waste (about
  2.8 lbs/person/day)
• 12 of potable water in the US
• 40 (3 billion tons annually) of raw
  materials used globally

5 Broad Areas of Application

• Sustainable Sites
• Energy and Atmosphere
• Indoor Environmental Quality
• Water Efficiency
• Materials and Resources

LEED Concept and Intent

• LEED is the standard for sustainable design
  worldwide.
• Design and construction practices that
  significantly reduce or eliminate the negative
  impact of buildings on the environment.
• LEED is a point based system that ranks the
  sustainability of a buildings design by
• Certified (26 32 points)
• Silver (33 38 points)
• Gold (39 51 points)
• Platinum ratings (52 69 points)
