This study was designed to help those involved with development and implementation of California’s Title 24, Part 6, Building Energy Efficiency Standards (“Title 24”) better understand real-world performance of dedicated outdoor air systems (DOAS). DOAS ventilation, which...

The purpose of this literature review is to present the current state of knowledge about the Controlled Environment Horticulture (CEH) industry and its energy and water use and to identify potential energy saving measures for consideration in future California Energy Code cycles. Gaps in knowledge...

The emerging technology assessed in this study is a packaged RTU that integrates a heat pump with an indirect-direct evaporative cooling (IDEC) system that is designed as a direct replacement for a traditional RTU. This project evaluates a Hybrid system in a field study and compares its...

This report describes the key economic costs and benefits, as well as emissions avoided, of a code change requiring zero emissions cooking equipment in new commercial food service kitchens in California. This research forecasts the costs and benefits associated with a 2022 intervening code change,...

This report describes the key economic costs and benefits, as well as emissions avoided, of a Title 24 code change requiring zero emissions cooking equipment in new residential single- and multi-family homes. This research forecasts the costs and benefits of a 2022 intervening code change, which...

This study evaluated the performance of unitary heat pump water heaters (HPWHs) operating in a shared configuration (each unit served four apartments) in an affordable all-electric multi-family project located in Davis, CA. The shared configuration allowed the HPWHs to be placed in close proximity...

The SCE’s Technology Test Centers (TTC) evaluate a variety of technologies in controlled environments that mirror real-world conditions and customer experiences. This generates comprehensive performance data and innovative test methods which are used by SCE customers, policymakers, and utility...

The aim of this sub-project is to collect data on electricity consumed by equipment in newly-constructed homes that are either required by health and safety codes or are considered necessary to make the house attractive to buyers. This aspect of residential energy use has not been studied but...

Emerging technology evaluation of refrigerated display case shelf edge guiding vanes. This technology is applicable to all users of open medium temperature refrigerated display cases. Sectors include supermarkets, and convenience stores. Any cold merchandising that utilize an open display case...

This project’s goals are to test optimization of connected thermostats and other loads via voice commands based on TOU rate peak times and customer preferences. Voice interactions related to energy (usage, estimated bills, best times to use appliances, etc.) will undergo evaluation to determine...
