Laboratory test a combination pre-cooler and fan/compressor speed controller provided by a major manufacturer installed with WCEC control algorithms. Use laboratory-test data to refine algorithms and optimize controls as needed. Field test the Roof Top Unit optimization package using one RTU at a...

This study was a continuation of the Central Valley Research Homes (CVRH) project which began in 2012. The CVRH project converted four existing single family buildings in Stockton, California into unoccupied laboratory houses for the purpose of evaluating energy savings associated with improvements...

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...

The objective of the PG&E Code Readiness Program’s retrofit DOAS, VRF and Networked Lighting Controls Demonstration at the UC Davis Facilities Management, Energy Conservation Office was to develop cost, performance, and occupant satisfaction data from a field demonstration site for a...

Run various simulations using a residential building model to determine water flow rates (from a fluid cooler) and air flow rates (from a residential air hander) required to meet cooling demand for single family residential home in climate zones in SCE territory. Design a condenser replacement...

Variable refrigerant flow (VRF) systems are well suited for automated demand response (ADR) because of their high efficiency, inherently flexible design, and more sophisticated controls available from the factory, relative to traditional air conditioners. Although VRF has been used successfully for...

Evaluates a smart water heater controller for energy efficiency in a controlled lab setting.  The product is a internet connected, learning controller that installs on existing gas/electric storage water heaters that meet specific manufacturer specifications.  The manufacturer also...

A retrofit device for HVAC rooftop units that can respond to DR signals. The controller can either shut off the unit or it can limit or vary the speed of the indoor fan and...

The technology to be evaluated is an automated, smart, internet connected zone control system for residential HVAC. This first phase of a two phase project will complete lab tests to verify that the zone control system can regulate comfort while not degrading overall system efficiency, while also...

This project is a small-scale field evaluation at two hotels in SCE territory of the HVAC energy savings of a phase change material (PCM) product. The PCM will be incorporated into artwork and other interior...
