![]() The Building Envelope Campaign technical team assisted Boulder Associates by calculating the fenestration values of the standard thermally broken aluminum frames used in this project, as the center-of-glass U-values for the HVIG were atypical.Īmerican Geophysical Union, Washington, D.C. The HVIG also allowed for a 13% reduction in visible light transmittance, decreasing glare on façades with higher solar radiation. ![]() In contrast to the U-value of 0.29 for low-emissivity insulated glass, the HVIG used on the project has a U-value of 0.071 on the north façade and 0.064 on the others. This building showcases emerging hybrid vacuum-insulated glass (HIVG) technology, which improves year-round energy efficiency and comfort by reducing thermal transmittance and convection at the windows. Energy-efficient design elements include masonry walls with 2 inches of continuous rigid insulation complemented by R-19 batt within the stud cavity, exceeding code requirements, and a canopy on the building’s south entrance that will accommodate a 99 kW photovoltaic array in the future. Let's take a look at the 2021 Better Buildings Building Envelope Campaign honorees (project descriptions and stats courtesy DOE's BEC program):īoulder Community Health’s West Medical Building, Lafayette, Colo.īoulder Community Health’s newest medical office building supports an eye clinic and an ambulatory surgery center for a leading Colorado retina practice. Honorable Mentions – buildings that do not meet a recognition tier but are still deserving of recognition.Role Models – buildings that meet one of the recognition tiers and also incorporate an additional advanced strategy or technology into their building envelopes, serving as role models within the industry.Retro 30 - retrofit projects that achieve 30 percent improvement.Retro 50 - retrofit projects that achieve 50 percent improvement.Novel 20 - new construction envelope projects that achieve 20 percent above a code baseline.Novel 40 - new construction envelope projects that achieve 40 percent above a code baseline.Organizations are eligible for recognition in four categories: These projects represent the inaugural class of DOE's Better Buildings Building Envelope Campaign (BEC) program, which was launched in 2020 to honor building teams for their leadership in envelope performance. Department of Energy (DOE) for their high-performance building envelope design. Boulder Community Health’s West Medical Building, with its hybrid vacuum-insulated glass installation and two inches of continuous rigid insulation, and the Lubber Run Community Center, Arlington, Va., with its "thermomass" insulated concrete walls, are among 14 projects to be recognized by the U.S.
