"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.

Call for Papers: The International Passive House Conference 2015

Experts on energy efficient building and retrofitting can now submit their abstracts for the 19th International Passive House Conference. The deadline runs until 1 October, after which the best projects and solutions will be chosen for presentation on 17 and 18 April 2015 in Leipzig, Germany. The conference will place a special focus on cost-effectiveness and developments in high performance Passive House building components (Photo: Congress Center Leipzig).

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

Component Award proves Passive House windows profitable

The winners of the first ever Passive House Component Award have been selected - a total of eleven Passive House windows received recognition. The real winners, however, are the building owners, for the results of this international competition demonstrate that it is possible to save money with highly efficient building components. The Award was presented at the International Passive House Conference taking place from 25 to 26 April in Aachen, Germany. more

Award for Heidelberg Passive House district now visible in the cityscape

Heidelberg's Bahnstadt is the world's largest Passive House district – recently awarded the 2014 Passive House Award at the International Passive House Conference for its exemplary nature. More than one hundred projects entered to compete in a total of six categories. The Bahnstadt district was far and away the favourite in the "region" category. The official award plaque has now been affixed to a kindergarten in the district, thereby making the international recognition visible to passers-by within the cityscape itself. more / photos

Designers and architects gear up for the future of construction

With the growing importance of energy efficient construction, the need for relevant knowledge is also increasing. Designers and architects around the world are therefore equipping themselves with the necessary expertise - the number of certified Passive House experts has now reached the 4,000 mark.
In June alone, several hundreds of examinations were given in more than
30 countries, in Europe and North America as well as in South Korea and
New Zealand. more

Passive House Conference showcases solutions for energy efficiency

The building sector plays a crucial role in climate protection, with over a third of total energy consumption in industrialised countries resulting from the use of buildings. At the International Passive House Conference in Aachen/Germany experts from around the world illustrated how this consumption can be reduced by up to 90 percent. The conference sessions, that covered the whole spectrum of energy efficient construction and refurbishment, made it clear that Passive House technology also gives rise to considerable cost savings. more

Accolade for world-class architecture in Passive House Standard

Building with an eye to energy efficiency is not only cost-effective, it can also augment architectural design. This has been proven by the winners of the 2014 Passive House Award. Seven projects were recognised: an apartment block in Berlin (Germany), a New York retrofit (USA), a seminar building in Goesan (South Korea), an art museum in Ravensburg (Germany), a building complex in Espoo (Finland), a terraced house in Philadelphia (USA) and an entire Passive House district in Heidelberg (Germany). more

Passive House: also a maximum energy efficiency solution for hospitals

Hospitals are among the most energy-intensive of building types. Here too, the Passive House Standard provides a solution that results in considerable savings. In Frankfurt (Germany) an older hospital building is currently being replaced by a new build with a focus on maximum energy efficiency. The result will be the world's first Passive House hospital. Critical issues regarding the execution of this project were elaborated in a baseline study. A compilation of the overall key results of this study is now available on Passipedia. more

New Passive House categories also rate building energy gains

The efficiency of the clearly defined Passive House Standard has been proven thousandfold – to also offer a reliable means of orientation regarding the additional use of renewables, the Passive House Institute now introduces new categories. These will not only take energy demand into account, but also energy supply through, for example, solar panels. In this way, Passive House offers an attractive solution for the energy revolution while serving as the basis for the "Nearly Zero Energy Building" of the European Building Directive. more

Update available for Passive House Planning Package PHPP

A new update for the globally established tool for planning energy-efficient buildings is now available: PHPP 8.5. Among the new features is the capability of working with up to 500 entry fields for areas and windows, especially useful for larger projects. An updated list of Certified Passive House Components has also been included. Perhaps most importantly, this update ensures PHPP compatibility with the new 3D tool designPH, which makes Passive House planning more comfortable than ever. more / order now

Certificate for first Passive House supermarket in Germany

Although fresh food needs continuous refrigeration, achieving a low energy demand is still possible. This has been demonstrated by the first Passive House supermarket in Germany: In the pilot project, highly efficient equipment reduces energy consumption while a well-insulated building envelope ensures that the waste heat generated by the refrigeration system is enough to cover space heating needs. Altogether, this Passive House supermarket promises 30 % in energy savings as compared to conventional supermarkets. more

Monitoring confirms efficiency of Passive House indoor pool

The municipal swimming pool operator in the German city of Lünen ventured into unchartered terrain when it decided to build its indoor swimming pool to the Passive House Standard some years ago. This courageous step has now paid off, as the monitoring results show. The savings in terms of energy consumption, for heating as well as for electricity, are substantial. Details will be presented at the International Passive House Conference. A general article on the topic is now available on Passipedia. Press Release

Passive House Days provide insights with a holiday feeling

The doors of hundreds of Passive House buildings were opened to the public during the second weekend in November. Three hotels in the Alps were among the more than 600 buildings participating in the Passive House Days event, offering a first-hand Passive House experience with a holiday feeling. In the German Allgäu and Austrian Vorarlberg regions, visitors were able to see for themselves that the Passive House level of comfort fulfils even the highest demands of holidaymakers. more

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
