Climate objectives are realistic with energy efficient buildings

Passive House experts present tried and tested solutions at the COP21 in Paris

COP21 Paris. Whether global climate objectives are met or not largely depends on the building sector. Over a third of the total energy consumption worldwide is used to operate buildings. At the same time, tried and proven solutions with which this consumption can be reduced to about ten percent already exist. How this works will be shown by Passive House experts at the COP21 in Paris.

Mobile student dorm in Passive House Standard inaugurated

Project in Vienna could serve as a model for low-cost accommodation for refugees

Mobile Passive House Darmstadt. Adaptable housing space is scarce in many cities. Even more so when affordability is decisive.

Pioneer Award for 1970s energy efficient house in Canada

Project manager Harold Orr to be honored at International Passive House Conference

The Saskatchewan Conservation House Darmstadt. This year's Pioneer Award, which recognizes the trailblazers of energy efficient construction, will go to Canada. In particular, the Saskatchewan Conservation House will be recognized, with which many features of the modern Passive House Standard were successfully tested in 1977. Against the backdrop of the oil crisis at the time, a broad team of experts looked at possibilities to significantly reduce the consumption of heating oil. Their studies showed that it was mainly a question of thermal protection of the building envelope. Canadian mechanical engineer, Harold Orr, one of the driving forces behind this project, will receive the Pioneer Award at the International Passive House Conference 2015 in Leipzig. Press Release

Energy efficient windows for retrofits receive Component Award

Winners to be honoured on 17 April at the International Passive House Conference

Winner of Component Award 2015 Darmstadt. The winners of the second Component Award, this year for Passive House windows for energy efficient solutions in the context of retrofits, have been selected. The joint first prize went to Optiwin for their "System Connecta" and Lorber / Pro Passivhaus-fenster for their "Smartwin Compact S" window. The main challenge in this competition was that the product had to show a degree of flexibility since refurbishments are often carried out in a step-by-step manner. Therefore, ideal windows had to deliver excellent results during the transitional period as well as after the completion of all refurbishment measures. The award will be presented on 17 April at the International Passive House Conference 2015 in Leipzig. Press Release
