DHW was produced with tankless coils in both boilers. EN-POWER GROUP s main scope consisted of: 1. Replacement of the single-stage absorption chiller with two 200-ton two-stage natural gas-fired absorption chillers. This upgrade increased the cooling plant s COP from 0.62 to Additionally, the use of the boilers for steam production was eliminated for cooling. 2. The 200-ton chillers that were installed have the capacity to be in heating mode. Each chiller-heater has a heating capacity 1,950 MBH. During the winter months, the new chiller-heaters support a new 100 HP EASCO hot water boiler. The new heaters are all equipped with fully-modulating burners. 3. The 100-HP boiler is a DHW-priority heater. The boiler was installed along with a double wall plate and frame heat exchanger, 200-gallon DHW tank, and electronic mixing valve. 4. Additional upgrades consisted of updated EMS system (Heat Timer HWR- Platinum) and a building-wide lighting upgrade. Conformance to originally proposed schedule and budget: Yes.

5 The Camelot was equipped with a ton single stage absorption chiller with a COP of The chiller used steam from two 400-HP steam boilers, which were also used for DHW production. EN-POWER GROUP s main scope consisted of: 1. Replacement of the single-stage absorption chiller with two 200-ton two-stage natural gas-fired absorption chillers. This upgrade increased the cooling plant s COP from 0.52 to Additionally, the use of the boilers for steam production was eliminated for cooling. 2. The DHW system was upgraded by installing separate indirect natural gas-fired DHW heater. The installed equipment includes two 2,500 MBH (83% efficient) water heaters, two 200-gallon storage tanks, one electronic mixing valve. 3. The 50-HP condenser pump was upgraded with a new NEMA premium efficiency pump controlled by a new 2-speed controller. The new controller is designed to operate at half-speed when only one chiller operates, significantly reducing electric costs as only one chiller operates 75% of the time.

The installed equipment includes one 3,000 MBH (83% efficient) water heater, two 119-gallon storage tanks, and one electronic mixing valve. 4. The heating controls were replaced with a Heat Timer MPC Platinum unit, which utilizes thermal and space lockouts. To institute space locktout, several in-unit temperature sensors were installed throughout both buildings. Two new zone valves were installed in order to optimize the control upgrades. 5.
