This Fact Sheet provides an overview of the Better Buildings Workforce Guidelines project. The Department of Energy (DOE) and the National Institute of Building Sciences (NIBS) are working with industry stakeholders to develop voluntary national guidelines that will improve the quality and consistency of commercial building workforce training and certification programs for five key energy-related jobs.
While the availability of “big data” about building energy performance is increasing in response to market demands and public policies, the lack of standard data formats is a significant ongoing barrier to its full utilization. To overcome this barrier, the U.S. Department of Energy (DOE) and Lawrence Berkeley National Laboratory (LBNL) developed the Building Energy Data Exchange Specification (BEDES).
BEDES is designed to enable the exchange, comparison, and combination of empirical information by providing common terms and definitions for data about commercial and residential building’s physical and operational characteristics, energy use, and efficiency measures.
This paper describes the BEDES development process, scope, structure, and plans for implementation and ongoing updates.
This 6-page technical design fact sheet by ComEd, about window-to-wall ratio, explains why the quantity of exterior glazing is likely to have a greater impact on energy consumption and occupant comfort than any other decision in the design of a building.
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.
NREL has developed the novel concept of a desiccant enhanced evaporative air conditioner (DEVap) with the objective of combining the benefits of liquid desiccant and evaporative cooling technologies into an innovative “cooling core.” Liquid desiccant technologies have extraordinary dehumidification potential, but require an efficient cooling sink. Today’s advanced indirect evaporative coolers provide powerful and efficient cooling sinks, but are fundamentally limited by the moisture content in the air.
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.
