The Texas LoanSTAR program is an eight year, $98 million revolving loan program, funded by oil overcharge dollars, for energy conservation retrofits in Texas state, local government and school buildings. The program began in 1988. Public sector institutions participating in the program must repay the loans according to estimated energy savings from an energy audit. As part of this program, a statewide energy Monitoring and Analysis Program (MAP) has been established. The major objectives of the LoanSTAR MAP are to: (1) verify energy and dollar savings of the retrofits; (2) reduce energy costs by identifying operational and maintenance improvements; (3) improve retrofit selection in future rounds of the LoanSTAR program; (4) initiate a data base of energy use in institutional and commercial buildings in Texas.
DescriptionFour levels of metering systems have been developed for the energy monitoring program. These accommodate the necessary requirements with the funds available for monitoring retrofits. For sites where the retrofits in individual buildings are less than $50,000-$100,000, savings are determined from utility billing data before and after retrofits and no separate meters are installed. Such sites are called "level-zero" sites. This level requires no monitoring equipment costs.
