  "Are the energy savings of the passive house standard reliable? A review of the as-built thermal and space heating performance of passive house dwellings from 1990 to 2018"
  
  The article deals in particular with the monitoring results of completely recorded settlements, which the Passive House Institute accompanied with careful research approaches. The core statement of the study is that the Passive House standard has been functioning as projected for many years and that there is no relevant 'performance gap' (gap between the expectation and the actual measured result).

  "Durability of building fabric components and ventilation systems in passive houses" – Feist et al
  
  
• The Passive House standard can be applied to the whole range of residential, commercial, and special-use buildings, whether new builds or a retrofit. Thousands of Passive Houses have already been built for diverse purposes, in a variety of climate zones using different construction methods. The very first prototype was a terrace house with four residential units. It was built in Darmstadt between 1990/1991. This building, with typical masonry outer walls, concrete floor slabs, and a wooden green roof is a high-quality example of very energy-efficient construction. All relevant energy flows through the building envelope were accurately recorded over a period of more than 25 years. This data confirms that the energy consumption over the entire period is as consistently low as planned.
  
  This article examines in detail how the construction method has affected the indoor climate, indoor air quality and the durability of all components. In-depth analyses evaluate the maintenance cycles representative for this type of building. The principal characteristics of the components and the ventilation system after 25 years of operation were determined. The results are groundbreaking for the Passive House concept: proving the construction method is not only effective in significantly reducing energy demand but above all, it is also highly durable and exceptionally low-maintenance.
