Project Description

NOVI Energy was contracted, under eight separate contracts, by the U.S. Department of Veterans Affairs (VA) to study the feasibility of implementing renewable energy Ground Source Heat Pump (GSHP) systems at the various VA campuses.

Site Assessment: NOVI completed a walk down of the selected building’s electrical and HVAC systems at each of the eight site locations to document existing system conditions. A walk down of potentially available space for installing the ground loop heat exchangers was also performed. Site physical conditions were recorded and relevant information such as distances and measurements were documented.

Technical Evaluation: Building electrical and thermal loads were reviewed. In cases where building thermal loads were not available, computer generated energy calculations were completed to estimate heating and cooling loads and associated energy consumption. Where possible, the re-use of existing infrastructure was targeted.

Economic Analysis: A number of financial parameters such as net present value, adjusted internal rate of return, life cycle cost, cash flow analysis, and savings to investment ratio, among others, were calculated. Direct funding approach with VA ownership of the GSHP system was used as input to the financial analysis.
