outPHit outcomes


The outPHit project is resulting in a number of interesting outcomes –  be they informational materials, guidelines, protocols or tools. While most will also be published on this website under the corresponding categories, this list should serve to give an overview of the most interesteing project deliverables.

Decision Making Support

  • Summer Comfort Guideline
    With warming climate conditions, the topic of resilience to overheating is becoming increasingly important. High indoor temperatures are a matter of comfort and are highly related to health. This guideline for summer comfort has been written to raise awareness and aid building designers in developing a robust strategy to ensure thermal comfort all year round. The provided design aid helps identify effective passive cooling techniques and analyse potential summer comfort risks of a project.

  • Manufacturing Energy Assessment Tool
    Contrary to popular belief that the manufacturing energy of building components plays the decisive role in the overall energy balance of a building, in reality it is often the operating energy that is crucial. The Passive House Institute has therefore investigated appropriate methods for assessing both, manufacturing and operational energy.  The tool can be used to assess and compare single materials regarding manufacturing energy and CO2, opaque assemblies as well as glazing and window frames regarding manufacturing and operational energy and CO2 and assess whole buildings regarding manufacturing and operational energy as well as CO2.

  • Fact Sheet "Climate Neutral Building Stock"
    The Passive House Institute has just released a fact sheet on how to quickly achieve a climate-neutral building stock within the framework of outPHit. The document is based on the results of a study on how best to achieve 2050 climate goals within Germany's building sector.



  • Concept note for the performance verification of energy efficient buildings
    Verification of actual building performance has the potential to be the ultimate quality assurance step in delivering highly efficient buildings. The outPHit consortium is therefore developing a verified performance certification scheme as a standard step for final approval of deep retrofits to the EnerPHit Standard. This concept note outlines the consortium’s plans.
  • Simplified monitoring approach for energy parameters
    High quality deep retrofits not only reduce energy consumption to sustainable levels but also make for even surface temperatures, heightened thermal comfort and appreciably improved indoor air quality. The approach thus describes a pre and post retrofit monitoring process for energy relevant data as well as for indoor air quality including mould and airborne fungal spores.

  • Instructions for adequate monitoring equipment for living quality assessment
    Deep retrofits offer the unique advantage to not only reduce energy consumption to sustainable levels and cover a large part of the residual demand with on-site RES but also implement a holistic improvement of the indoor environment.  The large number of projects in a wide geographical area that are investigated as demonstration projects of the outPHit project offer the unique opportunity to apply a uniform sampling and evaluation method and derive comparable results. Here a documentation of the methodology of sampling and evaluation. Because the measurement of air quality should be done simultaneously with the collection of energetic measurement data, this document refers on the simplified monitoring approach for energy paramenters whereas the measurement of the air quality is depicted in more detail.

  • Adequate Net Zero Rating Approach
    As outPHit and the EU strive for a sustainable future it is vital to pick the appropriate yardstick. Inappropriate incentives could cause lock-in effects at a later date even if they sound reasonable at first glance. This approach picks up on the claims of the most discussed concepts and how they may steer the development and thus helps project managers navigate through the different concepts of “net zero” to ensure a reliable and robust assessment of building concepts with regard to carbon emissions and the transition to renewable energy sources.

Renovation plans

  • Renovation approach documents
    Detailed descriptions of the renovation approaches employed for many of the project's case studies are for download in the information section of each case study on the outPHit website. These documents deliver insight into how various outPHit case studies are being retrofitted to meet the EnerPHit standard for renovations in line with Passive Houe principles.and provide a comprehensive overview of each building in question, its condition before the retrofit and the planned improvements in terms of air tightness, technical systems, insulation and building components.
