Energy consumption trending can then be pulled from the BMS and be used to evaluate the building’s performance. ILLUSTRATION: COURTESY PNNL Bowman also likes Credit EAc3, Advanced Energy Metering, one of the credits that replaced M&V and can earn a point for metering all energy end uses representing 10% or more of total energy use in the building. LEED LEED (Leadership in Energy and Environmental Design) is an ... Advanced Energy Metering 1 0.9% System Level Energy Monitoring V V ...

Project teams contemplating certification under the LEED v4 rating system will note that advanced metering capabilities are necessary for meeting the Building-level Energy Metering prerequisite, as well as obtaining EA credits for Advanced Energy Metering and Demand Response under the BD&C, EBOM and ID&C rating systems described earlier. ... Building level energy metering; Commissioning tie in: This can be useful in assessing performance for Cx; A couple new credits: Advanced Energy Metering: All energy end-uses that contribute 10+% of the total energy consumption must be connected to a BAS. (LEED V.4 requires 3 yrs.) Enhanced Commissioning (LEED Credit EAc3) – Now 3-4 points! The extended version of this credit is EAc3, Advanced Energy Metering worth 1 point, which requires that all meters be connected to the BMS (Building Management System) and will log data at an interval acceptable to LEED. Required 2 2 LEED 4.0_EAc4 LEED v4 also includes a new prerequisite that takes building-level energy metering one step further. If the lighting is controllable from a central point, it may be able to support participation in a demand response program (EAc4, Demand Response, 1 point) or at least enable participation (1 point). 1 1 LEED 4.0_EAc3 Advanced Energy Metering : Use advanced metering and sub-metering to report and track hourly interval electricity use data by end-use categories that exceed 10% of total annual electricity consumption and maintain said records for rolling two year periods. EAp2: Minimum Energy Performance EAp3: Building Level Energy Metering EAp4: Fundamental Refrigerant Management EAc1: Enchanced Commissioning EAc2: Optimize Energy Performance EAc3: Advanced Energy Metering EAc4: Demand Response EAc5: Renewable Energy Production EAc6: Enhanced Refrigerant Management EAc7: Green Power and Carbon Offsets Advanced lighting control systems providing metering capability can support achieving EAc3, Advanced Energy Metering (one point). The new version now requires permanent metering that records energy use at intervals of at least one hour, and preferably more frequently. Advanced energy metering prerequisite. In LEED V4, incorporating metering strategies goes even further in earning points:Building-Level Energy Metering—earn points for permanently installed meters capable of load aggregation for whole-facility energy use (electricity, gas, steam, water, BTU, etc. If the lighting is controllable from a central point, lighting may be able to support participation in a demand response program (EAc4, Demand Response, one point) or at least enable participation (one point).
