The Western Cooling Efficiency Center (WCEC) has developed a set of criteria for test conditions, minimum energy, and water use performance for prototype cooling equipment. The WCEC has identified these conditions as indicative of western state climates. These criteria, named the Western Cooling Challenge (WCC), have been set forth as a challenge to manufacturers to improve the state-of-the-art space cooling products. The National Renewable Energy Laboratory (NREL) is to verify these criteria through laboratory testing at its heating, ventilation, and air-conditioning (HVAC) test facility in Golden, Colorado, which is uniquely suited to accurately measure the cooling performance, energy, and water use of advanced cooling systems.
This document represents the final project report for the Self-Correcting Heating, Ventilating and Air-Conditioning (HVAC) Controls Project jointly funded by Bonneville Power Administration (BPA) and the U.S. Department of Energy (DOE) Building Technologies Program (BTP). The project, initiated in October 2008, focused on exploratory initial development of self-correcting controls for selected HVAC components in air handlers.
To maximize the benefits of converting to light-emitting diode (LED) technology from the traditional high-intensity discharge (HID) technology used in most parking lot lighting, CBEA members developed a performance specificationPDF that should be applied to a specific site, rather than a specific product.
To maximize the benefits of converting traditional high-intensity discharge (HID) technology to high-efficiency alternative technologies, including LED, induction, and fluorescence, a CBEA Project Team developed parking structure lighting performance specifications that should be applied to specific sites rather than specific products.
A CBEA Project Team working to support the market introduction of high-efficiency troffers developed a specification that allowed for high-efficiency LED and fluorescent technologies, and addressed the 2'x2' category of troffer products. Version 3.0 of the Specification was released, expanding the specification to address 1'x4' and 2'x4' product configurations. Potential savings from applying the specification range from 15-45% on a one-for-one basis and up to 75% with the use of controls.
In order to seize the opportunities for improving energy performance in the United States, it is important to understand what drives American companies and building owners to adopt efficiency improvements and sustainability policies. The research in this report provides new insights on how to create high-performing buildings and how to make the right business case to seize these opportunities.
This document provides in-depth instructions and examples for creating useful information from the interval data gained from using the Energy Charting and Metrics (ECAM) tool developed by the California Energy Commission.
This guide explains the benefits and process of building commissioning thereby providing owners and other stakeholders a tool to improve building efficiency and operation. It is intended to be a resource, as well as a call to action, for building owners and facility managers who want to verify their buildings are not only operating as originally intended, but also as efficiently as possible. Commissioning of new construction and major renovations is the primary focus, although commissioning of existing buildings is also briefly discussed as well.
