Emulation highly recommended

The EU-funded project SINFONIA has enabled comprehensive energy retrofits to be carried out in Innsbruck in Austria and Bozen in Italy. The heating energy savings are substantial, with an average of 77 per-cent saved in the projects in Innsbruck. At the same time, the building retrofits now offer significantly greater thermal comfort. SINFONIA has thus provided proof of the enormous potential of deep retrofits for saving energy and protecting the climate. These insights will be transferred to other cities in Europe. The Passive House Institute presented 13 certificates in Inns-bruck confirming the high level of energy efficiency of the retrofitted projects. more

Passive House efficiency is a model for the future also for indoor swimming pools. This is demonstrated in a new report on the energy consumption in the "Bambados" in Germany. The running costs for this leisure pool are far below average. The concept is thus successfully providing an opportunity for financial savings, especially relevant for municipalities with limited budgets. The full report is now available online (in German). Further details were presented at the International Passive House Conference in 2016 in Darmstadt. more

Monitoring confirms energy efficiency of Passive House city district

The Passive House district of Bahnstadt in Heidelberg (Germany) has passed the test: according to a report on recent measurements, the values being strived for in relation to energy efficiency were met in full. In 2014, the average consumption of 1260 housing units with a living area of more than 75 000 m² was 14.9 kWh/(m²a). The statistically high number of projects built by different property developers and architects convincingly shows that a successful large- scale implementation of the Passive House Standard is possible. more

First multi-unit residential building certified to Passive House Plus

The combination of energy efficiency and renewables is the future-proof solution for all buildings, including multi-storey projects – this is demonstrated with a new build in Innsbruck, Austria: the apartment complex is the first of its kind to be certified as a Passive House Plus building. This concept is not just based on a theoretical annual energy balance, which is misleading in practice; instead, the actual amount of regionally and seasonally available renewable energy is taken into account. more

New designPH takes Passive House planning to a whole new level

Passive House planning has never been more convenient. The new designPH, a 3D model interface developed by the Passive House Institute, allows for graphic input of energy related design data. Details relating to the thermal building envelope and shading are entered automatically and can be optimised if necessary. The treated floor area can be gradually refined in order to simplify the design process. The results can be exported into the Passive House Planning Package (PHPP) with just a few clicks. more / order now
