This sub-project will evaluate the demand response capability of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducked systems. Testing will focus on one to two systems from three to five manufacturers. Lab testing and field testing will...

This sub-project will explore and document advances in product development for advanced refrigerants in refrigeration systems with the goal of identifying products for laboratory evaluation and field deployment. Advanced product development engineering, primarily built on the foundations of...

Laboratory refrigeration has not been extensively studied, with the exception of ULT freezers.  The largest insight into the energy savings potential comes from the ENERGY STAR Product Specification for Laboratory Grade Refrigerators and Freezers, published in 2016.  Data from 14...

Technology Evaporatively pre-cools condenser air, coupled with outside air pre-cooling. Field Test to determine electrical energy savings, water usage, construct ability, and maintenance issues associated with...

Field evaluation of 5 hotel/motel sites retrofitting existing commercial pool pump with variable speed controls. This effort will be used in conjunction with the market characterization in phase 1 to develop a work paper to deem this measure. The measure is currently offered in programs as a custom...

A temperature-modulated panel of parabolic solar thermal collectors is used to heat hot refrigerant from the discharge line, adding heat and pressure without adding electricity. It works with VFD or multi-stage compression systems and is able to reduce system energy usage by up to...

More than 20,000 green building and design professionals attend this event. Two building developers are partnering to build a zero-net-energy concept home. In support of this project, SCE will provide technology development support, content for a display on the future of zero-net-energy, and a...

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...

In 2013, ASHRAE Standard Project Committee (SPC) 207P was formed to develop a nationally-recognized laboratory method of test for Fault Detection and Diagnostics (FDD) technologies pertaining to commercial packaged rooftop unit (RTU) air-conditioning equipment. The purpose of the standard is to...

This technology increases system visibility and improves the management of building mechanical systems through better detection of events that waste energy or adversely affect occupant comfort. Building efficiency monitoring services provide the basis of a continuous commissioning process, energy...
