Trends: Why buildings?
“Public opinion is the lord of the universe” – Thomas Jefferson

U.S. energy and electricity consumption U.S. total energy consumption
Buildings present the greatest opportunities for energy efficiency U.S. Green Building Council
U.S. electricity consumption
Energy and jobs from green buildings •
Greater building efficiency can meet 85% of future U.S. demand for energy through 2030
•
Potential to generate 2.5M American jobs
•
Every year American economy loses more than $130B from leaky, inefficient building
•
Green building industry to contribute $554B to the U.S. GDP from 2009-2013 Source: McGraw Hill; US Green Building Council
Government: Biggest consumer – LEEDing by example •
The federal government itself: – is the single-largest energy user – owns and operates some 500,000 buildings – announced a 28 percent greenhouse gas reduction target – owns 187 LEED-certified projects
•
Of 26,000 non-residential projects in LEED pipeline, 30 percent are government-owned (federal, state & local)

Minimal incremental cost implications • • •
•
Average incremental cost of 1%-2% of total construction cost Average payback of 2yrs Financial benefits include: – Lower energy consumption – Lower waste disposal – Lower water costs – Lower environmental and emissions costs – Lower operations and maintenance costs – Savings from increased productivity and health Major corporations have constructed green buildings – Examples: IBM, PNC Financial Services, Toyota, Ford, Interface, Haworth and Eaton

Energy & Atmosphere – Key to LEED building performance
Energy efficiency is the single largest contributor to the LEED credit points
Optimize Energy Performance – Maximum EA points
Optimizing Energy obtain maximum number of LEED credit points within Energy and Environment category and score higher rating
Optimizing energy: Key to LEED and continued high performance
Optimizing energy: From design to operation •
Starts integrated design
•
Must install systems to automate temperature and lighting
•
Anticipate renewable energy sources
•
On-going measurement and verification
•
Train building operators
•
Involve building occupants
Optimizing energy throughout the Building
