D.7.8 Metering
Monitor the actual performance of individual Fort Carson buildings through metering. In new buildings, metering verifies that sustainable design and operational goals are met or detect when the buildings are not performing as designed. Metering also helps identify opportunities for improving performance in existing buildings.
Record both electrical consumption (kWh) and electrical demand (kW) to determine building performance. Electrical demand is the time average value over a sliding 15-minute time frame. It is important to note that metering alone cannot save energy; however, regularly collecting and recording meter data and looking for unexplained changes can be a tool for assessing and identifying performance problems.
The Energy Policy Act of 2005 (known as EPAct or H.R. 6), Section 103 directs federal agencies to meter electricity use in all federal buildings by October 1, 2012, using advanced meters or metering devices that provide data at least daily. The Guidance for Electric Metering in Federal Buildings recommends metering natural gas and water use as well.
The following is recommended for Fort Carson:
-
Install submetering equipment for measuring lighting loads, HVAC system loads, and equipment loads of more than 20 kW.
-
Further subdivide the HVAC system metering to separately measure ventilation fan use and cooling plant use for large buildings with complex HVAC systems, such as laboratory buildings.
-
Install gas meters in all buildings having gas service, preferably connected to the automated meter reading system. Separately sub meter large process gas loads, if they exist.
-
Install water meters in all buildings with water service, preferably connected to the automated meter reading system. Separately sub meter large water use systems, such as a cooling tower.
