1. 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
Environmental Impact of Buildings (why does it matter?) US Commercial Buildings Facts:
65.2% total US electricity consumption
> 36% total US primary energy use
30% total US greenhouse gas emissions
million tons of US construction/demolition waste (about lbs/person/day)
12% of potable water in the US
40% (3 billion tons annually) of raw materials used globally

4. 5 Broad Areas of Application
Sustainable Sites
Energy and Atmosphere
Indoor Environmental Quality
Water Efficiency
Materials and Resources

5. 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 building’s design by:
Certified (26 – 32 points)
Silver (33 – 38 points)
Gold (39 – 51 points)
Platinum ratings (52 – 69 points)

6. Why engineers (and you) should care…
Discipline:
MEP 28 points 41%
Architect/LA %
Civil %
Constructor 4 6%
Undefined 5 7%
Totals 69 points 100%
