Ventilation systems strongly recommended


With the start of the cold season, attention is increasingly shifting to schools and the question of how the risk of infection with the Sars-CoV-2 virus in classrooms may be reduced. The German Environment Agency recommends frequent air replacement; in schools that do not have ventilation systems, this air exchange should be achieved by opening the windows. The German Environment Agency expressly advises against mobile air purification units as a substitute for ventilation with fresh air. These mobile appliances should only be used in addition to active ventilation. The Passive House Institute endorses this recommendation and draws attention to the advantages of a ventilation system with heat recovery.

Latest trend: healthy living spaces!


Not only is the demand for home ownership increasing, awareness relating to a healthy living environment is also growing. Those participating in the Passive House Open Days will be able to see and experience for themselves how Passive House buildings not only protect the climate but also contribute to a healthy living environment. From 6 till 8 November 2020, residents all around the globe will open their Passive House homes to the public. Many of these offers will be virtual tours, but personal visits are also possible.

Build better than required by code!


This year the final applause was shared in the chat window: the participants expressed their appreciation for the 24th International Passive House Conference, which was held as an online event for the first time on account of the COVID-19 pandemic. Over the past three weeks, more than 800 participants around the world tuned in and listened to the lectures on energy efficient construction and retrofit solutions from their own screens.  The virtual Passive House Café was open 24/7 for international networking. The conference conveyed two important messages, amongst other topics: deep energy retrofits need to be carried out on a broader scale, and construction practices must exceed the mostly inadequate code requirements for energy efficiency. The 25th International Passive House Conference will be held in autumn 2021 in the German city of Wuppertal.

For climate protection and a healthy home!


The opening was a success: for the first time, the Passive House Institute welcomed the participants of the 24th International Passive House Conference in front of their computer screens instead of in a full conference hall. Despite the time difference, viewers from around the world logged into the online conference for the opening plenary. Professor Wolfgang Feist made it clear that energy efficient buildings are an essential aspect of global climate protection. In addition, they have a positive effect on the health of the inhabitants. The climate researcher Professor Stefan Rahmstorf explained that global emissions had to be reduced quickly. Tickets for the conference will continue to be available until 8 October 2020.

Pointing the way – then and now


Construction of the first Passive House in the world started 30 years ago in Darmstadt, Germany. The building physicist Wolfgang Feist had developed the Passive House standard prior to this. In the autumn of 1990, he started putting theory into practice with the construction of the private terraced housing complex. Since then, countless buildings have been built to the climate-friendly Passive House standard around the globe. Current projects and research findings will be presented at the 24th International Passive House Conference from 20 September until 8 October 2020. The Passive House Institute presents ten reasons for attending the online conference.

Hospital a step closer to certification


The world’s first Passive House hospital, currently being built in Frankfurt, Germany, is a step closer to certification: an airtightness test for the building, which spans 78,000 square metres of gross floor area, was extremely successful. The Passive House Institute in Darmstadt has been consulting on this pilot project right from the start, including the initial planning phase. It has now been tasked with the certification of the project. A baseline study on the implementation of the Passive House standard in hospitals was carried out in advance by the Passive House Institute on behalf of the German Federal State of Hesse.

Congratulations for the 1000th certificate


Another success story from the world of energy efficient construction and renovation: the Passive House Institute has recently issued the 1000th certificate for a Passive House component. There is a great range of quality approved building components now available, and many manufacturers have recognised the potential of certified components for energy efficient buildings. Things looked completely different almost thirty years ago when the first Passive House building in the world was being constructed.

"We can still do it!"


Professor Wolfgang Feist opened with a clear message: "We can still halt the climate crisis. To do so, we need to make the right decisions now and then act upon them."  The founder of the Passive House Institute also highlighted the parallels between the COVID-19 and the climate crises. In addition, Feist explained how improved energy efficiency in buildings and a significant change in the areas of mobility and energy could limit the extent of dangerous climate change. "We cannot change the past, but we can change the future! It will be hard work, but we can still do it!"

The effort is definitely worth it!


Low operational costs for heating and electricity and a high standard of living comfort are possible at the same time: the latest session of the Research Group for cost-effective Passive Houses addressed the issue of social housing and how it can be implemented in a cost-effective and energy efficient manner. During an associated excursion, many participants visited the PassivhausSozialPlus in Darmstadt which is a nationwide model project for social housing.
