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.

The Smart Monitoring and Diagnostic System (SMDS) is a low-cost technology that helps building owners and managers keep rooftop air conditioner and heat pump units (RTUs) operating properly at peak efficiency. The SMDS technology has the potential to significantly benefit small commercial buildings, which predominately use RTUs for space conditioning. Through the Better Buildings Alliance, a field demonstration was conducted at four sites using two SMDS prototypes. This case study provides a summary of the field demonstration results.

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.
This guide provides an overview of the different energy audit options available and information on how to select an energy auditor.
Pacific Northwest National Laboratory (PNNL) with funding from the U.S. Department of Energy's Building Technologies Program (BTP) evaluated a number of control strategies that can be implemented in a controller, to improve the operational efficiency of the packaged air conditioning units. The two primary objectives of this research project are: 1) determine the magnitude of energy savings achievable by retrofitting existing packaged air conditioning units with advanced control strategies not ordinarily used for packaged units and 2) estimating what the installed cost of a replacement control with the desired features should be in various regions of the U.S. This document reports results of the study.
This series of fact sheets was developed by the U.S. Department of Energy’s Hospital Energy Alliance. These fact sheets help hospital and healthcare institution owners and operators use effective, energy-efficient technologies and practices to decrease energy consumption and its related costs and to address energy-related environmental issues. Each fact sheet covers a particular area of potential savings in healthcare facilities and includes one or more hospital case studies: Building Envelope Fact Sheet, Boilers Fact Sheet, Chillers Fact Sheet, CHP Fact Sheet, Existing Building Commissioning Fact Sheet, Energy Management Program Fact Sheet, Fast Paybacks Fact Sheet, Ground Source Heat Pumps Fact Sheet, HVAC Fact Sheet, Integrated Building Design Fact Sheet, Lighting Fact Sheet, Plug Loads Fact Sheet, Water Efficiency Fact Sheet.
The Walmart Supercenter in Leavenworth, Kansas, offered a test case to determine whether an LED system could meet the CBEA specification and be competitive with conventional systems when maintenance and energy costs were factored in. The LED system was compared to two systems: a 1,000-watt (W) pulse-start metal halide (PMH) and a 400-W PMH. This case study provides initial results and results after two years.
The Commercial Building Energy Alliance (CBEA) Lighting and Electrical Project Team developed a performance specification to help building owners and operators maximize the benefits of converting to solid-state lighting (SSL) technology from traditional high-intensity discharge technology. This specification provides information about both the luminaire and how the site should be lighted. It can be customized as building owners work with lighting designers, engineers, or SSL manufacturers to provide lighting solutions for different locations.
The Commercial Building Energy Alliance (CBEA( Lighting and Electrical Project Team developed this performance specification for LED refrigerated display case lighting. This is a project-level specification, as opposed to luminaire-level. As such, it provides users with the ability to evaluate system performance relative to specific project requirements. This specification can be customized as needed for each project.
The Commercial Building Energy Alliance (CBEA) Lighting and Electrical Project Team developed a High-Efficiency Troffer Lighting Specification that sets performance requirements for high-efficiency LED and fluorescent troffer products in 2x4, 2x2, and 1x4 configurations. While LEDs have a strong potential to meet this specification, the specification is technology neutral.
