Energy Conservation Studies of Existing HVAC Systems

A recent experience at ZBA in industrial energy conservation was investigating the energy savings potential of modifications to existing air handlers and to a central chilled water plant. Major system changes and new energy saving equipment require high cost to realize savings. This type of initial study is critical to assure that projected savings can be realized. The following examples are from an electronics manufacturing facility. Over 140 air handlers serving offices, laboratories and clean room manufacturing areas were investigated. The design cooling load of the central plant for the 12 building site was approximately 20,000 tons
