The Scope of Work See Appendix A called for the study of the economic feasibility of providing a cold thermal storage system at the central chiller plant serving the Fort Leonard Wood 600 Area in order to reduce electrical demand charges. In the Entry Interview, Mr. Doug Cage requested that the analysis include the potential for expansion of such a system to serve the 700 and 800 Areas as well. It was agreed that this would be done if the analysis indicated that a cold thermal storage system would be economically feasible for Area 600. Essentially, the systems are modular in nature, so that installed costs would be a multiple of the number of Areas served, not including any extraordinary costs which might be incurred as a result of special conditions which might be encountered as a result of system expansion. B. Building Data The 600 Area study area is comprised of two different build types, mess halls and barracks. The mess halls are all essentially identical with the exception that site orientation varies by building. The same is true for the barracks buildings. The following table summarizes building data. BUILDING TYPE QUANTITY FLOOR AREA EACH Barracks 10, 25,878 sq.ft. Mess Hall 4, 7,140 sq.ft. Present Energy Consumption and Demand A baseline case was calculated under the basis that the future chilled water plant for the area under analysis would be served by a centrifugal chiller. this was done because there is no existing baseline condition against which thermal storage systems may be compared. The existing chiller serves Area 600 plus a portion of Area 700. In addition, its age is such that it is reasonable to expect that it will be replaced in the near future. Assuming that replacement would be done by centrifugals is, we believe, both reasonable and proper.
