Persistent Commissioning, Persistent Value

Abstract

This case study showcases the energy savings, operational insights, and continuous economic benefits that end-use customers realize by employing persistent commissioning (PCx) tools and practices through a strategic utility program. EnerNOC and Pacific Gas and Electric Company (PG&E) collaboratively developed and deployed an energy efficiency incentive program targeting commercial real estate and high-tech office customers. The program employs a combination of monitoring based commissioning (MBCx) tools, diagnostic software, and O&M best practices which enable customers to make intelligent energy management choices and ensure persistent savings. PG&E's MBCx Program funds EnerNOC to provide both a software as a service (SaaS) platform, called EfficiencySMART, and MBCx engineering services for a full twelve months at no cost to the customer, based on installed energy savings. Thus far, the program identified over 3million kWh, 150 kW, and 200,000 therms in savings. One third of the savings is currently installed and the remainder is expected to complete within the next year.
