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.

Comprehensive commissioning can greatly improve the quality and energy efficiency of commercial refrigeration systems. This guide provides direction to owners and managers of commercial and industrial facilities that use refrigeration systems to help ensure that project requirements are met and that owners' expectations are achieved. This includes retail grocery, food service, refrigerated warehousing, and industrial refrigeration systems. The guide was produced as an ASHRAE special publication with funding from DOE/NREL.
This report outlines the technical protocol used to generate Department of Energy's Commercial Building Energy Asset Score for commercial buildings, explains the scoring methodology, and provides additional details regarding the Asset Scoring Tool. This report also describes alternative methods that were considered prior to developing the current approach. Finally, this report describes a few features of the program where alternative approaches are still under evaluation.
To maximize the respective benefits of open- and closed-loop systems, and minimize their limitations, the California Lighting Technology Center (CLTC) developed a dual-loop photosensor control system for skylight applications. The system features a control algorithm that monitors the open- and closed-loop photosensors and controls the electric light to provide the designed light level. It also automatically recalibrates nightly to adjust to long-term changes to the interior space. Results show the dual-loop technology delivers more consistent lighting and greater energy savings.
