Superior Performance, Lasting Efficiency
At AllenBuilt, Inc., we offer the option of building to Phius (Passive House Institute of the US) standards, known for creating some of the most energy-efficient homes in the world. Phius-certified buildings reduce energy use by up to 85%, ensuring superior performance and comfort over time. Homes built to Phius standards drastically cut energy consumption through advanced insulation and ventilation. Phius homes offer better indoor air quality, promoting a healthier environment. These homes maintain their efficiency and comfort for decades.
While Phius certification is optional, AllenBuilt ensures seamless integration when chosen, combining energy efficiency with quality craftsmanship.
