A Principal from Bridgestone Associates, working for ICF International, Fairfax, VA, managed and conducted a preliminary assessment of solar pv opportunities for all US Postal Service facilities. This was part of a larger study on alternative and renewable energy options for the more than 30,000 USPS facilities. The scope of work encompassed all types and sizes of facilities, including mail processing centers, post office buildings, and other support centers. Because many of the smaller buildings are leased with utility costs included in the lease monthly payment, these were excluded from the study because (1) there would be no energy cost savings to the USPS, and (2) the term of the lease was less than the required payback period of the equipment. Even with these facilities excluded, there were many thousands of facilities analyzed throughout the USA ranging from a few hundred to many hundreds of thousands of square feet.
