Pacific Gas and Electric Company (PG&E) implemented a Zero Net Energy (ZNE) Production Builder Demonstration that supported six builders in California in designing and monitoring a ZNE house. Each builder received technical support from start to finish to upgrade one of their existing...

This technology increases system visibility and improves the management of building mechanical systems through better detection of events that waste energy or adversely affect occupant comfort. Building efficiency monitoring services provide the basis of a continuous commissioning process, energy...

Project SummaryIn this study, we demonstrated a fast DR system architecture for DR resources participation in ancillary services using the OpenADR 2.0b. One objective was to measure if response time would be 4 sec or less, with response time defined as time to send signal, get response, and...

Project SummaryIn support of California’s strategic plan to accelerate the penetration of energy efficiency technologies, this report presents the findings of a field evaluation of a plug load monitoring and control technology in an office building. The work was executed by Alternative Energy...

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...

Project SummaryThe purpose of this study is to determine the effectiveness of passive Phase Change Materials (PCMs) in cold storage freezer applications. The PCM technology is designed to melt and freeze at a specified temperature based on the specific needs of a particular freezer. By increasing...

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...

Project SummaryThis project tests the capabilities of the Simergy version 2.1 Title 24 Module 2013-3c for nonresidential compliance with California Energy Code Title 24 Part 06 using the performance approach. Simergy was developed by Digital Alchemy. In addition, Simergy is compared to the...

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)...

A desktop study was performed to evaluate the accuracy and usefulness of an online service that infers home thermal performance characteristics from electricity consumption (from Green Button data) and weather (from the vendor’s proprietary network of stations). The service provides customers...
