What is Passive House?
The Passive House design approach takes advantage of material performance characteristics to create a building structure that needs very little supplemental heating or cooling to provide year-round occupant comfort, dramatically reducing the home’s annual energy consumption. To achieve this high level of energy efficiency, Passive House designers carefully evaluate how to assemble the building envelope to achieve optimal performance in four key areas: superinsulation, air-sealing, passive heating (solar gain) and effective ventilation. Because windows play an important role in each of these four critical categories, window selection is often a major part of the Passive House design discussion.
Window manufacturers like Colorado-based Alpen High Performance Products recognize that supporting the Passive House movement requires dual focus on producing windows of superior quality and performance and making accurate, third-party verified performance data for their products readily available for use in Passive House design software.
With this in mind, this spring Alpen HPP enlisted in the Passive House US (PHIUS) Product Performance Data Certification Program and is pleased to announce they are the first North American window manufacturer to have received Heating climate zone accreditation.
The results exceeded even our own expectations built around previously certified NFRC performance values, with whole-window performances as low as U-0.128 BTU/hr*ft2*F and 0.728 W/m*K.”
Alpen HPP has been a pioneer and industry leader in manufacturing super-high performance insulated glass products since 1981, and award-winning fiberglass windows since 2008. Having developed a series of fiberglass windows around high performance building needs, Alpen HPP is quickly becoming a favorite supplier among architects and Passive House consultants who appreciate domestically-produced windows of superior quality, performance and innovation.
