ESPC IMPLEMENTATION AT THE NATIONAL ANIMAL DISEASE CENTER

摘要

The facilities at the United States Department of Agriculture, Agricultural Research Service, National Animal Disease Center (NADC), located in Ames, Iowa, support a scientific staff of approximately 230 persons conducting research on animal diseases with economic importance to the US livestock industry. Annual energy consumption has been on the order of 520,000 Btu/sqft and annual energy expenditures exceed $1.5 million. The opportunities for energy and energy cost savings are significant and the Center is participating as an initial site for the DOE SuperESPC program. Preliminary ESCO proposals have identified more than $500,000 of annual cost savings, as well as improvements that will improve the comfort for building occupants and reliability of Center infrastructures. Anticipated ECMs include lighting, incinerator stack heat recovery, VAV retrofit and HVAC controls, air pump replacement, propane-air mixing stations, as well as back-up generation equipment, and a combustion turbine for co-generation. It is anticipated a delivery order will be issued for some or all of the proposed ECMs and implementation will begin during 1999. From the perspective of a facility manager and engineer with recent experience, the paper will reflect upon the processes of identifying potential ECMs, development of project goals, working with an ESCO and contracting specialists, evaluating technical proposals and ESCO proposed ECMs, consideration of M&V approaches, developing agency management support, and working with the ESCO during construction installation. Positive and negative aspects of the process will be reported in order to help prepare facility managers to implement successful ESPC projects at Federal facilities.
