Phius is a nonprofit environmental services organization based in Chicago, Illinois, that aims to decarbonize the built environment by making high-performance passive buildings the mainstream standard. It trains and certifies professionals, maintains and updates a climate-specific passive building standard, certifies passive buildings and high-performance products, and conducts research to advance high-performance design and construction. The organization’s work targets building teams, developers, and owners seeking to reduce energy use, offering verification and certification to ensure projects meet the standard; passive building methods emphasize super-insulation, tight envelopes, efficient windows, energy recovery ventilation, and passive solar strategies, with designs able to use as little as 40% of the energy for heating and cooling compared with conventional buildings. Phius operates within the environmental services sector as a standards- and certification-focused institution devoted to decarbonization, aiming to support healthy living and planetary well-being through a locally tailored, globally applicable standard. In 2026, Phius announced an expansion of its work into Canada, signaling geographic growth.
