ZNE facilities are distinct from other buildings that are simply energy efficient due to three main features: ultra-low energy use, onsite renewable energy to match consumption, and a robust monitoring system to enable detailed measurement and verification activities. The County of San Diego has 4 ZNE buildings in operation and several more in process. This session will illustrate how M&V is a critical aspect of the County's ZNE initiative, by examining the following topics: the County's philosophy of submetering for ZNE, an overview of how to acquire the optimal metering system, and lessons learned from 5 years of experience soliciting, designing, constructing, and operating ZNE buildings.
