Sacred Heart Schools completed construction of its Stevens Library for lower and middle school students in August 2012. The library is a 6,300 ft2 all-electric building. It was designed and constructed to achieve Zero Net Energy (ZNE) performance--based on total site energy), to meet the Living...

This project was a field assessment of indirect evaporative cooling for ventilation air for a mall in Fairfield, CA in which a new RTU was retrofitted with a direct evaporative pre-cooler at the condenser inlet, and a water to air heat exchanger at the ventilation air inlet. This study was...

This field study is evaluating the potential and current DR capabilities of climate-appropriate air-conditioning (AC) systems, such as evaporative cooling and variable capacity heat pump systems. Targeted DR and EE programs can help reduce high peak demand caused by increased AC use and address...

This project is a field study evaluating the potential and current DR capabilities of climate-appropriate air-conditioning (AC) systems. Targeted DR and EE programs can help reduce high peak demand caused by increased AC use and address uncertainties with respect to generation and consumption...

The goal of this project is to develop a methodology for determining the potential energy and peak-demand savings associated with sealing large buildings: commercial, hospitality, and dormitory style buildings. This includes developing models for the energy use and demand associated with leakage in...

The purpose of this project is to perform a laboratory assessment of fault detection and diagnostics technologies (onboard and in-field) on a packaged rooftop unit air...

Evaporatively cools incoming condenser air of air-cooled HVAC equipment. The purpose of this project is to test the feasibility of installing a technology on existing rooftop AC units that lowers the incoming condenser air temperature. The technology uses water evaporation to accomplish this air...

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...

Sweetwater Spectrum, a planned community of four single-story residences and a community center located in Sonoma, CA, is designed to serve adults with autism spectrum disorders. The project was initiated as one of several zero net energy demonstrations and provided the opportunity to evaluate...

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...
