Air conditioning loads drive peak demand and contribute to overall electric power consumption in California. In the summer, cooling loads are highest in the middle of the day when air conditioners are the least efficient. Rejecting waste heat from an air conditioner to a swimming pool rather than...

Ongoing commissioning (OCx) is an innovative approach to managing buildings – it provides continuous improvement in the operation of building systems. OCx is a multi-step implementation process, followed by a step-by-step continuous improvement cycle. Implementing this process within...

This report summarizes the conducted research, sources and findings. One finding is that available information is indeed not sufficiently detailed and up to date to accurately quantify power management software savings potential. A larger scale study remains nevertheless questionable, for several...

According to a study by the California Energy Commission (CEC), the agricultural sector accounts for 79 percent of California’s water use, which corresponds to 4 percent (over 10 GWh annually) of the state’s electricity use (CEC, 2005). One potential strategy for reducing agricultural...

Phase One of San Diego Gas and Electric’s Digital Billboard Project “Digital Billboard Use in California: ET14SDG8011” consisted of a description of digital billboards’ technology, preliminary energy profile, and a California market characterization. The final report,...

The purpose of this project was to conduct laboratory testing on the Indirect/Direct Evaporative Cooler (IDEC) to characterize its performance across typical cooling season weather conditions in climate zones 7 and 10.  The IDEC provides cooling very efficiently using only two sets of fans and...

This project evaluates market-ready connected plug load devices for opportunities in plug load programs. Unlike previous approaches that focus only on the programmatic or technology side, the approach used in this study evaluates the intersectionality between technical capability and program...

The objective of this project was to evaluate the possibilities for Demand Response (DR) using connected ecosystems currently available in the market. Current residential demand response programs focus on the control of single communicating devices such as Direct Load Control (DLC) switch connected...

For purposes of this project, a vendor managed BMS was selected, that focuses on fast food restaurants, other quick service restaurants, and convenience stores with significant on-site refrigeration and heating, ventilation, and air conditioning (HVAC) equipment. Other controllable building systems...

This IOU Pilot/ET Project had three main goals:Demonstrate the technical feasibility of ZNE retrofits in public K-14 schools statewide through 13-18 geographically and demographically diverse projects.Disseminate lessons learned regarding the technical design process and the implementation process...
