Certification Criteria for Energy Retrofits with Passive House Components

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.

How do we get there?

Holistic Energy Reduction Retrofit ≠

Weatherization

Sports car?

• Set goals for performance and design• Overlay architectural program• Make the home safe for people (code compliance)• Control temperature, air, and moisture• Add ventilation• Make the envelope air- and weather-tight• Add continuous insulation to meet the energy goals• Assess moisture transfer through shell• Implement robust climate zone-appropriate assemblies• Reduce energy demand by 2/3 and air-leakage 10X to

meet Passive House retrofit standard (EnerPHit)
