The objective of this advanced water heating initiative is to overcome market barriers and challenges associated with HWPHs through the development of a coordinated, statewide effort and alignment of existing and new programs, policies and technologies. The initiative will increase the adoption of...

The purpose of this project was to conduct laboratory testing on the Indirect/Direct Evaporative Cooler (IDEC) to characterize its performance across typical cooling season weather conditions in climate zones 7 and 10.  The IDEC provides cooling very efficiently using only two sets of fans and...

Gathering of Upstream Chiller performance data to enable performance curves to support the evaluation of Non-DEER Chiller measures. This work is expected to allow an increase in program participating by facilitating evaluation and deemification of high performance equipment currently not supported...

The purpose of this project was to evaluate the impact of low refrigerant levels on the cooling and heating seasonal energy performance of variable capacity heat pump (VCHP) systems operating in California homes.Prior studies have found that incorrect refrigerant levels are common in field...

This project seeks to evaluate a new technology being developed by leading manufacturers, that employs a high-lift centrifugal vapor compression to address the large building air-source hydronic heating market. This product seeks to replace fossil fired boilers in large buildings that currently do...

This study compared the effectiveness of remote HVAC monitoring with FDD to the traditional residential quality maintenance baseline. The emerging technology is an add-on unit and works on most residential HVAC systems, tracking the performance of an HVAC system real-time through 10 sensors...
