Energy Audits should be a standard part of building due diligence.  When you buy a car you know its fuel effiency, why not understand the same about the commercial building that you are buying?    Commercial building energy efficency can vary widely.   Two building of similar age and construction often vary as much as $1.00 per square foot per year in energy costs. 

Of course, the cost of energy is in the operating expense, so why pay $1,000 to $3,000 for an energy audit?   What you cannot see in the operating expenses is the opportunity to reduce.   Often a poorly preforming building can be brought in-line with its peer buildings for a minimal investment and these savings contribute directly to the building’s Net Operating Income.

In California there is another reason to do it:  the results of a basic energy audits will be a required disclosure item duirng leese, sale, and financing transacitons in 2010 for non-residentail buildings per AB 1103.    AB 1103 requires that non-commercial buildings are enrolled in EPA’s portfolio manager program and that the 1 to 100 rating given by EPA Portfolio Manager is given to the prespective tenant, buyer, or lender.
