TCAAP Energy Integration Resiliency Framework <br />Energy Efficiency Strategies <br /> <br /> <br /> 67 <br />establish the SB 2030 process into the commercial development RFPs, as the SB 2030 process provides <br />an overarching framework for pursuing high commercial efficiency performance. The process for how <br />to use SB 2030 is described above. <br />4.3.4. Sub-metering <br />Commercial and multi-family building sub-metering (Policy White Paper, p. 31) is included as an <br />important consideration because it is a relatively low additional design cost when considered up front, <br />but has the potential to help maintain low energy use since tenants directly see and pay for their <br />energy use. <br />Sub-metering has been shown to save up to 21% in leased building spaces.16 The material, software, <br />and labor cost for each sub-meter point ranges from $5,000 to $7,500. Several metering companies <br />provide sub-metering services by owning, operating, and maintaining the meters. Monthly fees are <br />based on the type of service needed and the quantity of sub-meters served, but costs per sub-meter <br />range from $150 to $400. <br /> <br />Value Add for Sub-Metering <br />Item Application Level(s) Primary Use <br />Energy Procurement and billing Building Management <br />Baselining & optimizing building performance Building; System Management; Diagnostics <br />Project energy measurement & verification System; Circuit Management; Diagnostics <br />Equipment and plug-load diagnostics Tenant; Circuit; Device Management; Diagnostics; <br />Utility efficiency programs <br />Occupant awareness and behavior change Tenant; Circuit; Device <br />Management; Diagnostics; <br />Utility efficiency programs; <br />Research <br />Table 24: Value add for sub-metering17 <br /> <br /> <br />16 “Tenant Occupants of Green Office Buildings: Driving the Market for Improving Existing Building Stock” McGraw-Hill Construction and <br />CBRE.
