The HVAC retrofit controller uses dual temperature sensors (supply air and return air) and a proprietary control algorithm with predictive analytics to improve operation of an HVAC system. This laboratory test project will explore energy efficiency potential of the HVAC retrofit controller, on a...

The Study’s goal was to investigate whether Title 24 energy code compliance requirements and energy simulation rulesets for RTU/economizer systems adequately reflected real world performance in California climate zones and make recommendations based on the investigation findings. The Study...

San Diego Gas & Electric's Emerging Technologies (ET) program performed a measurement & verification (M&V) study of Phase Change Material (PCM) for commercial customers. PCM was studied in a high school classroom setting. This high school is located in climate zone 10 with the...

Conduct AMI data analysis of individual commercial customers using the AMI Customer Segmentation (AMICS) modeling approach. The California Public Utility Commission (CPUC) recently approved Southern California Edison’s (SCE) application for a High Opportunity Programs or Projects (HOPPs) HVAC...

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 project seeks to evaluate a DIY heat pump system with a typical window AC unit. The goal is to determine for a given cooling load if this technology can provide higher efficiencies with comparable installation costs to window AC...

This study was a continuation of the Central Valley Research Homes (CVRH) project. The CVRH project converted four existing single family buildings in Stockton, California into unoccupied laboratory houses to study residential energy saving opportunities. Variable capacity heat pump (VCHP) systems...

The proposed Demand Flow project includes both hardware and software components. The intent of the project is to increase plant efficiency by automatically resetting plant flow and temperature...

This project will evaluate and demonstrate new potential for otherwise unrealized demand response capability from new-to-market variable capacity commercial HVAC systems in Southern California. Southern California Edison (SCE) and their customers will benefit from this effort by unlocking a new...

In small to medium sized offices, spaces are commonly conditioned by a single-zone HVAC unit with one thermostat in the control zone. However, a zone can consist of multiple spaces, making it difficult to meet the individual comfort needs of each space. Therefore, single-zone units in commercial...
