Enerphit – what it is, how to undertake it, a case study

Learn about the EnerPHit standard, a Passive House standard intended for refurbishment projects. Passive House is a leading approach to creating energy efficient homes (#TDChallenge23).

EnerPHit allows for more wiggle room compared to the traditional standard to accommodate retrofitting challenges, while still achieving the superior comfort and performance Passive House buildings are known for.
