21 Passive House Institute Dr. Wolfgang Feist Rheinstraße 44/ Darmstadt Germany EnerPHit and EnerPHit +i 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.

22 How do we get there?

23 Holistic Energy Reduction Retrofit Weatherization

25 The Plan for Success 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)
