International Passive House Conference 2016 in Darmstadt

Big anniversary for the International Passive House Conference: from 22 to
23 April 2016 this central event for energy efficient construction will take place for the twentieth time running. A special focus of the programme will be on cost-effective ventilation systems. The conference takes place in Darmstadt – the city in Germany, in which the first Passive House was constructed in 1991 and where the first international experts' conference on this subject was held five years later.

First Passive House projects in Greece and Turkey now certified

With intelligent architecture, considerable energy savings are possible in every climate. The latest examples of this now stand in Greece and Turkey. Three terraced houses and an environmental education centre are the first buildings to fulfil the criteria of the Passive House Standard in these two Mediterranean countries. The specific challenges for energy efficient construction in regions with a warm climate will be presented based on these and other projects at the International Passive House Conference 2016 in Darmstadt this April. more

New Passive House office building in Frankfurt now certified

Curved façades, but a straightforward energy concept: a new office building in Frankfurt, Germany, clearly shows the potential of sustainable building design, with an architectural style that is not only elegant but also intelligent. The result is a 90 percent reduced heating demand and perceptibly increased comfort due to high indoor air quality. The building thus meets with the criteria for the Passive House Standard. Details will be discussed in April during excursions as part of the International Passive House Conference 2016. more

Designing sustainable buildings made fun: PHPP 9 now available

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 takes into account energy generation on or near the building as well. The new features also include innovative options, for example for heat recovery from shower water or for profitability calculations. The practical use of the tool is facilitated by means of automatic verification and plausibility checks. more

"Active for more comfort" - Passive House brochure as online flipbook

How does a Passive House work? Which requirements exist with regard to components, planning, design, and project implementation? What is it like to live in a Passive House, what has already been built, and why are Passive Houses such an attractive investment? In order to competently answer such questions, the International Passive House Association (iPHA) has created the informational brochure "Active for more comfort". A new edition of this brochure is now available as an online flipbook.

New study shows cost saving potential for indoor swimming pools

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 will be presented at the International Passive House Conference in 2016 in Darmstadt. more

World's largest building retrofitted to EnerPHit Standard now certified

A completely modernized university building in Innsbruck, Austria demonstrates the energy saving potential available with refurbishments. Through integrated planning, the heating demand of the building was reduced from 180 kWh/m²a to just 21 kWh/m²a. The project thus meets the criteria of the EnerPHit Standard for retrofits with Passive House components – this standard, introduced by the Passive House Institute, is specially tailored to the particularities of retrofit projects. The certificate was presented at the official reopening. more

World's first Passive House Premium now certified

One of the world's most sustainable buildings stands in Bavaria: as the first of its kind, a mixed residential and commercial project in the town of Kaufbeuren has met the criteria for a Passive House Premium certification. With a heating demand of only 8 kWh/m²a, it is uniquely energy efficient. At the same time, a 250 m² photovoltaic system on the roof produces renewable energy. The doors of this new building were open to the public on 14 and 15 November within the framework of the international Passive House Days 2015. 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

New Passive House Classes presented at conference in Vancouver

Clearly-defined criteria for combining the international Passive House Standard with renewable energy sources are now applicable: the Passive House Institute's new guidelines for building evaluation have come into effect with the introduction of a new version of the planning tool PHPP at the NAPHN15 Conference in Vancouver. Not only is certification according to the Passive House Classes Plus and Premium now possible worldwide, but the EnerPHit criteria for retrofits are also now applicable in all climates. 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 architecture book presents "Passive House Award" winners

A new book showcasing the winners and finalists of the international "Passive House Award" shows that energy efficient construction is not only profitable, it is also an enrichment for architecture. The book is available in a bound version and in digital form as an online flipbook. All of the award-winning buildings are presented with many photographs and illustrations. Technical details which are relevant for the energy balance are also explained in detail. In addition to the book, there is a poster exhibition on the Award. 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

Passive House Conference: Solutions for a sustainable energy future

The Passive House Standard enables every building owner to benefit from the energy revolution, with certified components ensuring cost-effectiveness. This basic concept was the focus of the International Passive House Conference, held from 17 to 18 April 2015 in Leipzig. Speakers from all over the world presented exemplary projects and solutions for building systems, ventilation units and windows. An exhibition provided specific examples of products currently available on the market. Conference Review

Passive House also provides answer to energy efficiency in the tropics

Whether in India, Singapore or Brazil – Passive House principles also work in tropical climates. The focus, however, changes: while heating is typically not needed in these climates, efficient cooling and dehumidification methods play an important role. A new study by the Passive House Institute gives concrete design recommendations, showing that, in the Passive House of the tropics, energy demand is also drastically reduced. The entire study is now available online on the knowledge platform Passipedia (member area). more
