Energy-efficient home with off-the-shelf products and systems
As newspaper publishers, the Allens have a deadline-driven schedule and were looking for a low-maintenance, low-carbon place of respite. Coming from a large but dark 1970s suburban home, they craved light, openness, and connection to nature. Perched on a wooded north-facing slope overlooking a canal, the site required a design that could balance competing interests for northern views with ample southern exposure for light and warmth. The lower south-facing roof is designed for photovoltaic panels, which, when installed, will supply most, if not all of the home’s annual energy needs. With a modest custom-home budget, the design team optimized the architecture for minimal waste and used off-the-shelf products and technologies in creative ways to achieve performance targets for Passive House air tightness.
Off-the-shelf products and materials were used with Passive House design and detailing strategies
Blower Door Testing was performed during construction and utilized to chase air leaks and ensure air tightness
With the slope and view facing to the north, the site is opposite of true passive design, which orients to the south
The roof was designed with a split gable to bring light from the south to the north half of the house
