Facilities Manager | january/february 2015 | 43 entailing some level of Re-Cx implementation, then roll into the SPP. Using the energy consumption data from FY2010, these buildings comprise a total annual cost of $3.9 million. Assuming a 20 percent annual usage savings were to result from a Re-Cx process, cost savings would be around $780,000/ year. An SPP would protect the investment of Re-Cx and sustain this savings. The total estimated annual cost savings of the facilities under consideration would be in the neighborhood of $1 million, and provide a revised total annual utility cost of $4.58 million. A 5 percent annual degradation of this cost is $229,000 in the first year. This would result in the cost of the FTE having an annual payback of approximately six months.
