Residential retrofits

• Peer-reviewed article: "Retrofit with Passive House components"
  Ever wondered how the detailed requirements for PHI's retrofit standard "EnerPHit" were defined? The Passive House Institute (with external co-authors) published a paper in the renowned Energy Efficiency journal. It describes the outcomes of the extensive research that led to this cost-optimal building energy standard. You can learn how EnerPHit addresses thermal comfort, indoor air quality, climate protection and hygrothermal performance. The authors present five international built examples, including measured energy consumption, costs and solutions. The data confirms very low energy consumption in EnerPHit buildings (in a range of ¼ to 1/8 of the original values).
