New builds / residential buildings
- Peer-reviewed article:
"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.

New builds / Non-residential buildings
- Passive House Quality, Police Administrative Building – July 2017, short version
As an overall evaluation, it can be stated that a functioning energy-efficient administrative building was realised, in which a high level of comfort has been verified. This was achieved with very low energy use on account of the extremely high quality building envelope and adapted building technology. The appropriateness of monitoring was again evident from the potential for improvement that was still available. The Passive House Standard once more has proven to be an easily implementable and practicable standard. It offers an excellent tried and tested solution for future building requirements, today.

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).

- Study – "smartwin compact – Economic optimum in the regions of Europe" – smartwin compact is a cost-effective and energy efficient window produced by the pro Passivhausfenster cooperative. The window, first place winner of the 2014 Component Award in the timber-aluminium category, comes in double, triple, and quadruple-paned varieties. This study uses the smartwin compact as the basis of an economic analysis investigating which of the three window variants makes for the most cost-effective option in each of a variety of climates. The study takes investment costs as well as energy costs over the life-cycle of the window into account.

Windows
- Windows in a step-by-step retrofit – In practice, windows and façades are rarely retrofitted at the same time, even though doing so would save costs, reduce thermal bridges and optimise solar gains. There are many reasons why retrofits are done in a step-by-step manner. Ideally, windows and façades should always be retrofitted simultaneously whenever possible. If this is not the case, the following tips can help.

The standards, EN 13829 and ISO 9972, do not provide sufficient information for the blower door measurement of such buildings. Depending on the height of the building, pressure differences occur, which are not negligible for the measurement. The requirement of the PH standard to not exceed a deviation of the pressure difference of 10% within the building envelope at any point, can no longer be met. This publication presents practical tips for the measurement of high-rises.

Planning guidelines for Passive House indoor swimming pools
- The energy demand of indoor swimming pools can be reduced significantly by consistently applying the high energy efficiency approach of the Passive House concept. This not only contributes to climate protection but also entails savings for the financial resources of a municipality. These guideline documents summarise the main research findings and provide recommendations to support the design, construction and long-term operation of highly energy efficient indoor swimming pools.

Embodied energy
- Study – "Optimum glazing in the regions of Europe considering the embodied energy" – It is evident, that the
U-value of glazing will decrease by increasing the number of panes and low-e-coatings, so the transmission losses through the glazing will decrease (just as the cooling load in cooling climates). At the same time, the
g-value decreases too, so the solar gains are decreasing as well. In addition, the embodied energy increases with the overall thickness of the used glass, inert gas and the numbers of coatings.
The task of this study was therefore to determine an overall energy balance (transmission losses, solar gains and embodied energy) over the life cycle of a glazing to carry out the best option in terms of the overall energy balance for the regions of Europe.

Hospitals
- Baseline study - implementing the Passive House concept in hospitals
Many of the 2,080 hospitals in Germany and others all over the world require retrofitting. Evaluations of consumption statistics show that hospitals are among the buildings with the highest energy consumption. To evaluate and tap the savings potential of retrofits and energy efficient new builds, the State of Hesse financed a study into the basic considerations when implementing the Passive House standard in hospitals. The study was especially timely for the construction of a new-build hospital, the Frankfurt Höchst Clinic.
Due to the demanding and consistent 24-hour use, as well as the higher temperature required in patient rooms, the Passive House Standard is particularly valuable for hospitals. The study also shows that if the energy demand is calculated using conventional methods, almost half of the future energy demand remains overlooked.
Conventionally built hospitals are often already equipped with ventilation technology. From there it is only a small step to installation of a controlled ventilation system with heat recovery in the buildings. Furthermore, the baseline study showed that despite the higher indoor temperature and the higher air change rate of the controlled ventilation system, the heating demand can be limited to 15 kilowatt hours per square metre of treated floor area per year (kWh/(m²TFAa) by using appropriate measures.
Lighting, hot water generation, a ventilation system and heating and cooling are among the highest consumers of energy in hospitals. Depending on the equipment, the sterile supply, magnetic resonance imaging equipment and computer equipment are also responsible for a high percentage of energy demand. Using existing technology, the demand for heating, lighting, ventilation, computer equipment, cooling and hot water generation can be reduced significantly.
Several processes in a hospital produce waste heat. It is undeniable that this waste heat should be used for other processes; for example, in the heating system via a heat pump. The investigation shows, however, that priority should be given to optimisation of the processes that produce waste heat.
