Energy Savings Performance Contract: Phase I & II
HSC began aggressive energy conservation efforts in 1999 when it completed a detailed energy audit for several of the buildings on campus. In 2001, a feasibility study was completed concerning the implementation of solar power on campus, but was concluded to not be a cost effective energy source at the time.
In 2001, HSC contracted with Tour Andover Controls (TAC), now Schneider Electric, to complete a two phase guaranteed energy conservation project. Phase I included:
- Lighting efficiency improvements
- Replacing two chillers
- Installing direct digital controls
- Domestic water conservation efforts
Phase I was a $3.2 million project financed through the Texas Public Finance Authority’s Master Lease Purchase Program. A measurement and verification plan was put in place along with training of university personnel. The energy and water reductions exceeded expectations and performance guarantee. According to EPA figures, the utility savings resulted in a reduction of CO2 emissions by approximately 25,425 tons, the equivalent of removing 5,085 cars from the road annually or planting 6,916 acres of trees.
In 2010, HSC began phase II of the Energy Savings Performance Contract with Schneider Electric. Phase II included:
- Motion sensor lights
- Window replacements
- Energy efficiency lighting in the buildings and parking garages
- Installing a computer power management system
- Mechanical upgrades to several building chillers
- Installation of a new water management package
Phase II was an $8.6 million guaranteed and self-funded investment. This phase was forecasted to save $835,000 annually, pay for itself in 10.3 years, and create $2.7 million in positive cash flow for the university. The environmental impact includes a reduction of over 2,400 tons of CO2 annually. The first two phases saved HSC $14.2 million in energy and operational costs.
Energy Savings Performance Contract: Phase III
In 2022, HSC implemented a 20 year Energy Savings Performance Contract to modernize the cooling demand for the university’s research labs. This project will provide us with $424,912 annual avoided costs over the next 20 years. The project includes:
- LED lighting
- Colling tower replacement
- Installation of campus chilled water piping
