The Rooftop Unit Comparison Calculator (RTUCC) compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost. This web application provides an alternative to complicated building simulation models, while offering more detail than simplified estimating tools that are commonly available. While simplified tools are typically based on full-load efficiencies and full-load equivalent operating hours, the RTUCC accounts for local climate and partial-load, as well as full-load efficiencies.

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.
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.
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.
The Commercial Building Partnership (CBP) paired selected commercial building owners and operators with representatives of DOE, national laboratories, and private sector exports to explore energy efficiency measures across general merchandise commercial buildings.
The Fire Station Efficiency Solutions Package aims to assist municipalities nationwide to reduce carbon footprints, lower utility bills, and increase resiliency by selecting improvements that will reduce energy and water use in existing buildings by at least 20%. This toolkit is a product of a collaboration between the City of Atlanta and Southface Energy Institute. Through this solutions package, municipalities and fire departments will be equipped to plan and implement individual and portfolio-level upgrades.
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 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.
