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...

Project SummaryThis report explores the potential role utilities may play in the emerging home energy management (HEM) marketplace and develops a roadmap to leverage, promote, and enable the use of these technologies for energy savings and grid load reduction. It takes a comprehensive view of...

Dispatchable pre-coolers have the potential to be used for utility load management if pre-coolers can be demonstrated to be a guaranteed demand reduction resource. Building on prior work testing evaporative pre-coolers, complete a laboratory study to determine the transient response and load...

This project builds on the 2016 Emerging Technologies report (https://www.etcc-ca.com/reports/field-assessment-residential-radiant-ceiling-panel-space-conditioning-systems) based on testing two types of radiant ceiling panels coupled with air-to-water heat pumps (AWHPs). Performance in the...

A temperature-modulated panel of parabolic solar thermal collectors is used to heat hot refrigerant from the discharge line, adding heat and pressure without adding electricity. It works with VFD or multi-stage compression systems and is able to reduce system energy usage by up to...

Evaluate energy management tool for campus, impacts of commissioning, interaction with grid and available distributed energy sources, and micro-grid...

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....

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...

This study demonstrated how existing constant air volume (CAV) RTUs may approximate a variable air volume (VAV) system to increase efficiency and comfort for the building’s occupants. Given that 60% of the U.S. commercial floor space is served by CAV RTUs, these dynamic air balancing systems...

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