This sub-project will evaluate the demand response capability of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducked systems. Testing will focus on one to two systems from three to five manufacturers. Lab testing and field testing will...

This sub-project will explore and document advances in product development for advanced refrigerants in refrigeration systems with the goal of identifying products for laboratory evaluation and field deployment. Advanced product development engineering, primarily built on the foundations of...

Technology Evaporatively pre-cools condenser air, coupled with outside air pre-cooling. Field Test to determine electrical energy savings, water usage, construct ability, and maintenance issues associated with...

More than 20,000 green building and design professionals attend this event. Two building developers are partnering to build a zero-net-energy concept home. In support of this project, SCE will provide technology development support, content for a display on the future of zero-net-energy, and a...

The goal of this three-month field assessment was to determine the efficacy of a physical water treatment (PWT) technology for cooling towers to determine energy, water, and chemical savings potential at a Southern California Edison (SCE) customer...

Ongoing commissioning (OCx) is an innovative approach to managing buildings – it provides continuous improvement in the operation of building systems. OCx is a multi-step implementation process, followed by a step-by-step continuous improvement cycle. Implementing this process within...

Lab and field evaluation of demand defrost controls for walk-in freezers. The purpose of the project is to quantify the energy savings achievable only defrosting on an as-needed basis as opposed to a...

The purpose of this project is to evaluate efficiency/performance of residential variable capacity heat pump (VCHP) systems. These are "traditional American-style" high static ducted systems. There will be one to two systems from three to five...
