Swimming with a clear conscience

Swimming pools constructed to the highly energy efficient Passive House Standard  can help relieve the burden on municipalities significantly in the long term. This is demonstrated by two Passive House indoor swimming pools in Bamberg and Lünen (Germany), for which the Passive House Institute provided consultancy services. The Passive House Institute evaluated the pilot projects and has now published recommendations in a free handbook for planning of energy efficient pools.  The handbook is also helpful for optimised operation of already existing pools.

China commits to climate challenge

The largest Passive House residential district in the world is currently under construction in the Chinese city of Gaobeidian. Joined by other success stories such as “Bolueta” in the Spanish city of Bilbao, home of the world’s tallest Passive House high-rise building, and the first certified Passive House hospital being built in Frankfurt am Main, Germany. The 23rd International Passive House Conference will reflect this global upswing in energy efficient construction. The organisers of the 2019 Conference invite all Passive House enthusiasts to join them in China. The call for papers is now open until December.
  Press Release





High-rise Bolueta ranks first

The developers and architects had set very high goals. With the Bolueta building they wanted to set a new Passive House record and at the same time ensure the quality of the building through certification. The project participants have successfully achieved both objectives. With a height of 88 metres, Bolueta in the Spanish city of Bilbao is now the tallest Passive House building in the world. The recently issued certificate is proof of its highly energy efficient Passive House Standard construction.

Passive Houses: cooler inside during summer heat!

On hot summer days, Passive House buildings can be noticeably cooler than conventional buildings. The excellent level of thermal insulation keeps the heat out, coupled with effective strategies such as “passive night cooling” ensure comfort in the summer months. Providing proof of a pleasant indoor climate in summer is also one of the requirements for quality assurance for Passive House certification. "Numerous practical examples in different climate zones very clearly show that Passive House buildings have a pleasant and cool indoor climate during heat waves. However, professional planning is crucial for this", says Zeno Bastian of the Passive House Institute.

"There's no alternative to Passive House!"

The speakers in the packed hall in Munich were unanimously clear on one thing: that the increase in construction costs in recent years was not caused by energy efficiency; instead, other parameters were responsible. In line with the theme of the 22nd International Passive House Conference "Passive House – it's worth it!" numerous speakers drew attention to the economic feasibility and affordability of energy efficient construction and retrofitting. At the conclusion of the event, Professor Wolfgang Feist surprised the more than 1000 conference participants as he announced that the 23rd International Passive House Conference in 2019 would be held in China.
  Press Release



Next Passive House Conference in 2019 in China

The next International Passive House Conference is to be held in 2019 in China. "We are aware that this decision may be surprising to some. However, it is in China where the most construction activities are currently taking place, and this will continue to be the case in the coming decades. Each new building brings with it an additional demand for energy for heating and cooling, therefore it is extremely gratifying that China is making serious efforts to radically improve the energy efficiency of buildings. There is still a chance of meeting the climate protection objectives," explained Professor Wolfgang Feist.

 Police set example for climate protection

With the completion of the new police administrative building, the German state of Hesse has shown how energy efficient construction works. The administrative building in Baunatal in northern Hesse contributes significantly to a reduction in the energy consumption of government buildings in the province of Hesse and thus promotes climate protection. This is one of the numerous outcomes of the monitoring carried out by the Passive House Institute on behalf of the Ministry of Economic Affairs in Hesse. Other government buildings in Hesse will profit from these findings, future buildings can be designed to be even better and even more cost-efficient.  Press Release




Affordable and energy efficient!

In view of the international climate objectives, providing both affordable and energy efficient living space has become a challenging task for cities and communities. Solutions for solving this dilemma will be discussed at the 22nd International Passive House Conference which will take place on 9 and 10 March 2018 in Munich. "Passive House – it’s worth it!" is the motto of this year’s Conference, which will be introducing many low-cost projects relating to energy efficient construction to the Passive House Standard. The Call for Papers has begun. Press Release




"You just have to use your head"
