Project SummaryThe goal of this study is to provide recommendations for integrating emerging technologies into energy efficiency incentive programs for existing Small and Medium Business (SMB) Packaged HVAC applications in Pacific Gas and Electric Company (“PG&E”) territory. To achieve the...

Project Summary Replacing existing and vintage gravity wall furnaces with high-efficiency models can save gas in apartments, average 35.5...

This project will leverage the efforts from ET13SCE7060 (Analysis of Next-Generation Home/Building Energy Management Systems) to conduct laboratory and field evaluations of currently available home/building area network systems. This activity will assess the systems’ effectiveness in implementing...

Project Summary This report documents a field evaluation of the Munters EPX 5000 installed at a grocery store in San Ramon, CA. The technology studied is an indirect evaporative and vapor compression hybrid dedicated outside air supply (DOAS) system. This study was performed after a lab...

The purpose of this project is to field-assess a Roof Top Units (RTU) retrofit technology that combines evaporative pre-cooling of AC unit condenser air with sensible pre-cooling of outside air. Assessment will study installation and operation issues, water consumption, peak kW reduction and kWh...

The goal of this project was to compare the capital costs of a Geothermal Central Utility Plant (CUP) to a Conventional CUP, estimate the energy cost savings, and determine the simple payback at a correctional facility development project in San Mateo County, California. This study was conducted to...

This project examines the site net energy consumption of a sample of units in the UC Davis West Village community. The primary goals were to (1) study energy consumption and production in order to determine if this West Village sample is achieving its zero net energy goals and (2) determine the...

The general basis of this technology is evaporative precooling of the ambient air prior to contact with existing air-cooled condensing coils. The idea is it lowers the entering air temperature on the outdoor unit. The compressor does not have to do as much work, which results in energy savings. The...

The objective of this project was to monitor the in-situ performance of a VRF-HR (heat recovery) system and provide performance characterization based on the data recorded.  The site is a 4-floor PG&E office building in Auburn, California which is in California Climate Zone 11.  The...

The purpose of the project to demonstrate capabilities of AutoDR enabled OCSTs in light commercial settings. This phase will field test a different vendor than phase 1, at a different fast food...
