Investigate problems and assess the feasibility of proposed solutions for distribution and sales of HVAC energy efficiency products. Observe and interview key stakeholders involved, including decision-makers and facilities personnel. Develop specifications and best practices for creating a market...

This project builds on the 2016 Emerging Technologies report (https://www.etcc-ca.com/reports/field-assessment-residential-radiant-ceiling-panel-space-conditioning-systems) based on testing two types of radiant ceiling panels coupled with air-to-water heat pumps (AWHPs). Performance in the...

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...

Dispatchable pre-coolers have the potential to be used for utility load management if pre-coolers can be demonstrated to be a guaranteed demand reduction resource. Building on prior work testing evaporative pre-coolers, complete a laboratory study to determine the transient response and load...

Evaluate energy management tool for campus, impacts of commissioning, interaction with grid and available distributed energy sources, and micro-grid...

Under the auspices of PG&E’s Zero Net Energy (ZNE) Production Builder Demonstration, Blu Homes built a 1,877 square foot all electric ZNE home in Loomis, CA. This report describes the results from monitoring the occupied home for a full year.The ZNE definition used for the design was...

Project SummaryIn support of California’s strategic plan to accelerate the penetration of energy efficiency technologies, San Diego Gas & Electric’s Emerging Technology program funded a study of rooftop package unit maintenance and control retrofit technology at two fast food...

The main goal of this Project was to characterize the behavior of radiant heating and cooling systems in order to provide information for designers that would reduce both the cost and the perceived risk associated with radiant systems. The aim is to improve energy and comfort performance by...

Project SummaryThis report describes the results from field demonstration of evaporative pre-cooling technology on commercial HVAC (heating, ventilation, and air conditioning) equipment for SDG&E (San Diego Gas & Electric) at a field site in California climate zone 10. This study seeks to...

This project involves a remote evaporative condenser retrofit for connection to packaged AC units. This technology replaces the packaged AC unit's air-cooled condenser with a separate, evaporatively-cooled condenser. One condenser can serve up to two AC units. This is a continuation of project...
