Evaluate potential water sources, including stored rainwater, for use with evaporative condensers. Systematically test influential water quality parameters (calcium, magnesium, alkalinity, pH, and hardness) on the formation of scale in bench-scale evaporative condensers. Construct and test a model...

Run various simulations using a residential building model to determine water flow rates (from a fluid cooler) and air flow rates (from a residential air hander) required to meet cooling demand for single family residential home in climate zones in SCE territory. Design a condenser replacement...

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...

Develop and refine a new building energy simulation tool that will allow users to estimate the annual savings that can be achieved from certain climate appropriate solutions. Develop and validate performance of evaporative pre-cooling of condenser air and outside air with this simulation tool....

Provide an internationally recognized performance standard whereby different evaporative pre-cooling technologies can be...

This project is an aggressive multi-disciplinary, comprehensive, whole building approach to designing and constructing a net zero energy retrofit of an existing low-income multi-family complex. To the best of our knowledge this will be the first Multi-family Net Zero/ Deep Energy Reduction (DER)...

Southern California Edison (SCE) is teaming up with EPRI and a large production homebuilder to design, build and monitor a new ZNE residential community in Fontana, CA. SCE will act as the project's lead on emerging DSM technologies, battery storage integration, electrical grid optimization and...

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...

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 multiple AC units. Project is a field assessment of one condenser serving (2) air...

Retrofit to existing RTU that steps supply fan speed in response to calls for cooling or heating. Technology controls outside air in response to occupancy sensors and CO2 monitors. The purpose of this project is to review the effectiveness of the above...
