Stakeholder Involvement
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 interesting project deliverables.
Available outcomes
District evaluation reports from Greece, Austria, Bulgaria and Germany
This study of renovation scenarios in a Greek, Bulgarian and an Austrian district, as well as for all of Germany, shows how renovations carried out with a rigorous focus on superior energy performance can avoid lock-in effects, leading to vast energy savings and significantly lower emissions, even at consistently more comfortable indoor temperatures. The scenarios for each district were conducted with DistrictPH, an open-source, Excel-based tool developed by the Passive House Institute, capable of calculating detailed energy balances for entire districts as well as their development over time.
Political recommendations based on the German scenarios in this study: Towards a climate-compatible building stockEnergy Performance of Buildings Directive revision
The Passive House Institute (PHI) welcomes the European Union's efforts to reduce greenhouse gas emissions. PHI recognises the recent attempt to introduce more clearly defined Zero Emission Buildings and minimum performance standards in building renovation to improve the building stock of the EU Member States towards climate neutrality. However, we fear that, particularly in building retrofits, the minimum requirements for the Member States will not be sufficient to reduce the energy demand of buildings to such an extent that it can be met with renewable sources only. We recommend further specifications and more ambitious requirements, specifically in building renovation.
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 the 2050 climate goals within Germany's building sector.
Towards a climate-compatible building stock
(Updated version with analysis of the Coalition Agreement of 2021)
In this study is shown that above all, it is a matter of using upcoming measures in the building for carrying out energy retrofits at the same time ("coupling principle"), and at a consistently high quality ("if you have to do it at all, do it right"). The additional investment will then be small, and it will be compensated for by the saved energy costs – that's climate protection not only at zero cost but also with additional profit. This opportunity can be used to undertake measures in addition, which can be implemented quickly as other "low hanging fruits", which will already accommodate dependencies and energy costs in the next winter.
The study is also available in a one-pager format.
