ECM DESCRIPTION Sample Clauses

ECM DESCRIPTION. Retrofit existing lighting fixtures with new energy efficient lighting fixtures, install motion sensors and implement daylight harvesting where applicable 38% Heating Season Length [Weeks] * Percent of Heating Season [%] ** Fraction of Heat to be Made‐Up [%] Heating Season Length [Hours] * Fraction of the year representing the heating season, as there are times during the year when the building is neither heated nor cooled. ** Fraction of the lighting reduction that has to be made up by the heating system; a portion of the lighting heat is released at night plus interior zones will have limited heating loads 31%

ECM DESCRIPTION. CM3 proposes to reuse the existing carbon dioxide sensor in the Return air plenum that will monitor the amount of CO2, which translates into the presence of people in that area. The CO2 sensors will modulate the outside and return air dampers to maintain a safe level of CO2 per ASHRAE standards. » Control programming for the requirements of this ECM » Commissioning of the new system. Currently two (2) condenser water pumps are running whenever the chillers are running even though most of the time only one chiller runs. There are three (3) 40 HP circulating pumps rated at 1200 GPM per pump with constant volume flow when the chillers are running. The water flows through both chillers even though only one is running. The existing butterfly valves will be automated to be both manual and automatic. These valves will close when the chillers are off and will open when the chiller is enabled to run. When one chiller is operating, only one pump will run. When two chillers are on, two pumps will run. The condenser water reset schedule will be revised to optimize savings from the chillers by resetting the condenser water temperature down during cooler months during the heating season. Both chillers will have the existing isolation valves modified with a new actuator. ▇▇▇.▇▇▇▇▇▇.▇▇▇ | 215.322.8400 | ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇. ▇▇▇▇ ▇▇▇▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇ » DDC controls will be provided for each new control valve, the condenser water reset will increase or decrease the condenser water temperature by varying the VFD speed of the cooling tower fans. » The CWS reset schedule will be modified to optimize savings. The predominant lighting technology within the district is T8, with a mix of T5 technology in some of the schools. LED lighting has been implemented on a small scale. Typical classroom – 3 Lamp T8 Linear Direct Indirect The main lobby/hallways on each floor have narrow linear wrap fixture that a good portion of the fixtures are missing lenses. Gymnasium – Has multiple different LED retrofits and existing Metal Halide, all of which are providing different light levels
