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.
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.
This guide discusses how to achieve greater energy efficiency through occupancy behavior analysis and energy auditing to create targeted and strategic behavior change.
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.
A brief introduction to Operations and Maintenance, the potential energy savings involved, and referral to the O&M Best Practices guide.
This guide provides an overview of the different energy audit options available and information on how to select an energy auditor.
Miscellaneous electrical loads (MELs) are building loads that are not related to general lighting, heating, ventilation, cooling, and water heating, and typically do not provide comfort to the building occupants. MELs in commercial buildings account for almost 5% of U.S. primary energy consumption. On an individual building level, they account for approximately 25% of the total electrical load in a minimally code-compliant commercial building, and can exceed 50% in an ultra-high efficiency building such as the National Renewable Energy Laboratory's (NREL) Research Support Facility (RSF). Minimizing these loads is a primary challenge in the design and operation of an energy-efficient building. A complex array of technologies that measure and manage MELs has emerged in the marketplace. Some fall short of manufacturer performance claims, however. NREL has been actively engaged in developing an evaluation and selection process for MELs control, and is using this process to evaluate a range of technologies for active MELs management that will cap RSF plug loads. Using a control strategy to match plug load use to users' required job functions is a huge untapped potential for energy savings.
