PHI has played a critical role in the development of the Passive House concept, a performance-based building standard that is energy efficient, comfortable and affordable at the same time. PHI retains a leading position in research on and development of construction concepts, building components, planning tools and quality assurance for especially energy efficient buildings. PHI makes its knowledge available including its research, its certification and its training programmes. PHI seeks to make the Passive House standard of building performance understood, achievable, and adopted by government, industry, professionals, and the public through research, education, advocacy, events, and building projects. PHI aims to advance energy efficiency in the built environment through stakeholder education, practitioner training, research and demonstration, network building, policy implementation, and project and product technical assistance, and by raising or developing applicable resources and tools.
To strengthen international collaboration, the International Passive House Association (iPHA), an initiative hosted by PHI, acts as global member network of Passive House stakeholders, including architects, designers, scientists, suppliers, manufacturers, contractors and property developers. With currently 23 international Affiliate Organizations, the iPHA network engages in coordinated dissemination and policy efforts to grow the Passive House Standard on the principle of thinking globally and acting locally.
