Energy and Water Savings

The Federal Energy Management Program (FEMP) design analysis team used an ASHRAE 90.1 base case laboratory model to determine the energy savings that could be realized from various energy saving and sustainable technologies.  The FEMP analysis revealed that the incorporation of the several energy measures would reduce annual energy consumption by 61 percent as compared to the base case model.  The reduction translates to 380.9 million British thermal units (MMBtu) and $4,300 each year, at current energy rates.  In addition, FEMP concluded that the capital cost increase to implement the measures would equate to roughly $37,300, or just 5.3 percent of the $708,000 construction costs, which was well within the standard project contingency of 10 percent.  Therefore, no additional funding would need to be requested.  The simple payback period of the energy conservation measures is ten years.

More importantly, dramatic savings will be realized through the elimination of the “outside” freezers.  Relocating the frozen storage samples to an appropriate indoor facility reduces the site’s annual energy consumption by 1,888 MWh, or 6444 MMBtu, and yields a cost savings of $20,000 a year.  This is equivalent to the average annual electricity consumption of close to 200 homes.
