Agenda



Trends and drivers of high performance buildings



Cost implications



Components of LEED® Certification



Optimize energy consumption



Real-life case study

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
