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...

Project SummaryThe main objective of this project is to evaluate how well the Honda Smart Home achieves the design goals of reaching zero net energy (ZNE) performance while providing a high level of service to occupants.  The project compares modeled energy use estimates to actual energy...

Project SummaryAn ET project could help the resolve the existing impasse regarding ductless mini-splits in the market, and would need to have a field demonstration component which allows actual performance to be compared to central split system heat pumps and develops best practices for the design,...

Project SummaryDemonstrate and Assess High Performance Envelope strategies for commercial buildings and how they interact with Lighting, Daylighting and Office Equipment Loads to better T24 2013 Code compliance by...

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...

Project SummaryEvaporative cooling building technologies take advantage of the latent heat of vaporization for water to provide comfort cooling. Indirect evaporative cooling technologies achieve this without adding water vapor to the zone supply air. The technology studied here provides condenser...

Project SummaryTraditional, single speed space conditioning equipment operates in one of two states: either on or off. When single speed equipment is operating, it provides 100% heating or cooling output at a fixed efficiency based on the ambient conditions. In recent years, manufacturers...

Project SummaryThis report describes the results from field demonstration of evaporative pre-cooling technology on commercial HVAC (heating, ventilation, and air conditioning) equipment for SDG&E (San Diego Gas & Electric) at a field site in California climate zone 10. This study seeks to...

Project SummaryVariable capacity heat pumps (VCHPs) have the ability to deliver capacity below and above their nominal rated capacity by changing the speed of the compressor and modulating ancillary components like fans and expansion valves. This flexibility allows for similar component sizes...
