CEE’s Nonprofit Mission
The Center for Energy and Environment (CEE) is a
nonprofit organization that promotes energy efficiency to
strengthen the economy while improving the

• We conduct research and develop programs so that:
• Businesses operate more efficiently and profitably;
• Government agencies and nonprofits spend less on facilities
and functions;
• Utilities achieve their energy-efficiency goals at least-cost; and
• Households save money and improve comfort.

What is Recommissioning?
Recommissioning is a systematic process to
improve the operation of existing buildings
so they:
• Actually meet the owner’s needs
• Use only as much energy as is necessary
• Optimize existing building systems
• Focus on large savings at low cost

• 37 different utility companies
• 3 offer study rebates
• 27 of 71 sites had one utility for electric and gas
• Means 2/3 have two utility companies
• All sites realized both electrical and gas savings
• Coordination of programs is uncommon

Summary of Most Commonly Identified
Energy Savings Measures
Note that an affected area of 412% means there
were 4.1 measures per building, on average

15. Pg. 15
Best Practices and Lessons Learned
Without a quality assurance process, we would not have known….
• Qualified providers who understand the specialty of
recommissioning are essential to identify all the
potential savings
• A good customer relationship will increase the rate of
implementation
• Programs should address all energy sources at a site
• Careful selection of buildings is necessary for a cost-
effective program; some buildings have minimal
savings opportunities.
