EnerPHit and EnerPHit+i Certification Criteria for Energy Retrofits with Passive House Components

Abstract

If an energy retrofit of an existing building meets Passive House criteria (for new builds), it,
too, can be certified as a Certified Passive House.
It is, however, often difficult to feasibly achieve the Passive House Standard in older
buildings for a variety of reasons. Passive House technology for relevant building
components in such buildings does, nevertheless, lead to considerable improvements with
respect to thermal comfort, structural longevity, cost-effectiveness over the building lifecycle
and energy use.
Buildings that have been retrofitted with Passive House components and, to a great extent,
with exterior wall insulation can achieve EnerPHit certification as evidence of both building
quality and fulfilment of specific energy values. The EnerPHit+i designation is applied if
more than 25 % of the opaque exterior wall surface has interior insulation.
The certification criteria for both standards are described below
