This is the final report for boiler research performed at UL Toronto and Intertek Cortland New York laboratories in support of publication of ASHRAE Standard 155P, “Method of Testing for Rating Commercial Space Heating Boiler Systems.” Standard 155P will rate the performance of commercial boilers...

Roof mounted, radiative sky cooling panel has a specialized film that cools when outside. These panels cool with minimal electricity, all day long throughout the year without evaporating water. The panels can be integrated into any new or existing refrigeration/HVAC system as an efficiency add-on...

The objective of this project is to evaluate the performance in the laboratory of a new-to-market 120-gallon commercial Heat Pump Water Heater and its ability to provide hot water in a more efficient manner and with lower total emissions. This water heater has a COP of...

Southern California Edison (SCE) provided a Letter of Commitment in support of LBNL’s proposal for the EPIC GFO 19-301 Group 4 EPIC solicitation, intending to cost share $300,000 ($150k / $150k from ET/DR). The project will develop and demonstrate an open-source energy and load management system...

Heat recovery ventilator (HRV) technology was evaluated as part of an EPRI research project funded by the California Energy Commission, titled the “Development and Testing of the Next[1]Generation Residential Space Conditioning system for California” [CEC EPC-14-021 project]. As part of the...

The goal of this project is to assess the energy and demand savings resulting from a solar assisted direct expansion (DX) system.  A field test was conducted in a 1,600 sq. ft. single-story residential home located within SDG&E territory. In this test, an emerging technology that consists...

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 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...

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...
