Passive House residents offer insights into their buildings

Open days in November make visits to many projects around the world possible

Passive House Days Low-cost, comfortable, sustainable – that's the future-proof formula for the buildings of tomorrow. During the Passive House Days from 13 to 15 November, everyone will be able to see how this concept is already working. Several hundreds of built examples will be open for viewing. Experts will demonstrate how these buildings function, while residents will talk about their experiences. An overview of the Passive House buildings participating in individual cities and regions around the world can be found on www.passivehouse-database.org. Press Release / Register your building

Designing sustainable buildings made fun

English version of PHPP 9 to be presented in Vancouver and London

PHPP 9 The tried and tested PHPP tool for designing energy efficient buildings is available in a brand-new version. This upgrade not only allows reliable calculation of the energy demand in accordance with internationally applicable criteria, it also takes into account energy generation on or near the building. Over the past few months a German edition of the PHPP 9 has already been successfully used in practice; the English version will be presented at the NAPHN15 conference on 1 - 2 October in Vancouver and at the UK Passivhaus Conference taking place on 20 October in London.

First multi-storey building certified to Passive House Plus

Housing complex in Innsbruck combines energy efficiency and renewables

Passive House Plus building in Innsbruck Darmstadt/Innsbruck. 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: 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 so that a completely sustainable supply system becomes possible.

Component Award for ventilation in residential buildings

Cost-effective systems for broad application to be honoured

Component Award 2016 Darmstadt. Ventilation with heat recovery is absolutely essential in energy efficient construction. The application of such systems in practice often fails due to high costs, though. In order to promote low-cost approaches which can facilitate the breakthrough of this key technology in the mass market, the Passive House Institute has announced the Component Award 2016 for ventilation solutions for residential buildings. All-inclusive concepts are being sought for an existing building, which are not only highly energy efficient but also economical. The Award will be presented at the International Passive House Conference 2016 in Darmstadt. Press Release

In order to provide reliable guidance for this combination, the Passive House Institute introduces two new categories for its building certification; in addition to the established Passive House Classic, there will be the Passive House Plus and Passive House Premium classes. A new evaluation procedure which also considers energy generation by the building itself will serve as a basis for this. The exact certification criteria and calculation details according to the renewable primary energy (PER) system are available on the online resource PassipediaPress Release
