Our building stock is generally inefficient. The energy that our buildings waste makes them both key contributors to climate change and amplifiers of energy poverty. Deep retrofitting to tackle this waste and improve building performance is thus rightly at the heart of building-related policies at all governmental levels. Yet while streamlining and approaches like the Energiesprong and serial renovation have helped standardise retrofitting methods or make them otherwise more accessible, the delivery of consistently high quality deep retrofits remains a challenge. OutPHit pairs such approaches with the rigour of Passive House principles to make deep retrofits more cost-effective, faster and more reliable.
On the basis of case studies across Europe and in collaboration with a wide variety of stakeholders, outPHit is addressing the challenges hindering the execution of high quality deep retrofits while facilitating the development of high performance renovation systems, tools for decision making and quality assurance safeguards.
