The Texas LoanSTAR Program - A model for funding energy efficiency retrofits Conference Paper uri icon


  • The Texas LoanSTAR Program, which began in 1988, produced over $118.5 million savings from energy conservation projects applied to state and local government buildings. One of the key features of LoanSTAR was the monitoring and verification of the savings. Nationally, LoanSTAR was served as a showcase for other states to follow. LoanSTAR M and V methods become the foundation for the USDOE's NEMVP, IPMVP and ASHRAE's Guideline 14P. However, from the success of the LoanSTAR Program, many lessons were learned which were not as highly publicized. This paper present an overview of 12 years of measured savings from the LoanSTAR Program, including the cost effectiveness of the LoanSTAR loans, trends in LoanSTAR funding, how to reduce the cost of a revolving loan program while maintaining quality control, and a discussion of the LoanSTAR emissions reductions.
