The adoption of Phius passive building standards in the United States, while demonstrating a robust upward trend, currently constitutes a small fraction of the overall construction market, which is predominantly characterized by buildings constructed to meet minimum code requirements. Phius certified buildings offer substantial advantages over typical code-built houses, most notably in their superior energy efficiency, which translates to significant reductions in operational energy consumption and associated costs. Furthermore, these high-performance buildings provide enhanced indoor air quality, increased durability, and a greater level of resilience against extreme weather events and power outages. The number of Phius certified projects and the total square footage of these projects have been steadily increasing across the US, reflecting a growing interest in and adoption of these advanced building principles. Moreover, the integration of Phius standards into the energy codes of several states and municipalities indicates a growing recognition of their value in achieving ambitious energy efficiency and sustainability goals. This report aims to provide a comprehensive, data-driven analysis of the current market penetration of Phius standards within the US construction sector, offering a comparative perspective against conventional code-compliant building practices and assessing the implications for the future of sustainable building in the nation.
