To help California reach SB1383 short-lived climate pollutant goals, this project will demonstrate the energy efficiency and environmental benefits of low GWP refrigerant based systems for walk-in freezers and coolers. There are thousands of these units that keep food product at the right...

Evaluate the performance of standard and high efficiency A/C units at hot and dry conditions. The assessment involved testing pairs of 3-ton split and 5-ton RTUs. Each pair consisted of standard and high efficiency...

Bi-level and demand response (DR) capabilities will be demonstrated in corridor lighting for commercial and institutional market sectors through the use of step-dimming and/or full-dimming ballasts combined with occupancy sensors and DR controls in retrofit applications. The objective of the Smart...

A hybrid AC and DC platform that is being designed as an open architecture focused on reducing or eliminating inefficient AC to DC conversions between power sources and light sources by converting and distributing power in DC. This platform is designed to improve reliability and energy efficiency...

Evaluate performance of HVAC and refrigeration applications using advanced refrigerants. This project intends to explore and document advances in product development for advanced refrigerants in the refrigeration and HVAC...

This Field Assessment is to test the potential energy performance of homes that have crawl spaces that will be sealed and made to become part of the building envelope, hence conditioned space. This Field Assessment seeks to discover other, non-energy benefits to Conditioned Crawlspaces (CCS). The...

The Project Purpose is to identify lessons learned while retrofitting residential homes to ZNE levels. Observations in the field during the ZNE retrofit projects will form the basis of this report. The expected outcome of this project is to educate builders, trades people as well as other...

Laboratory test of an indirect evaporative pre-cooler on the outside air intake of a packaged AC unit, along with a direct evaporative pre-cooler on the AC unit's...

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...

Design and pilot of a central CO2 heat pump water heating (HPWH) system and measurement & verification (M&V) work at the proposed 117-unit, 157,000 SF Culver City Senior Housing development. The project includes primarily independent living apartments with efficiency kitchens and a large central...
