EU Project - PassReg (2012-2015)

Passive House Regions with Renewable Energies

Making frontrunners visible – supporting potential frontrunners. This is the motto of the PassREg project, funded within the European Commission’s Intelligent Energy Europe programme and headed by the Passive House Institute. As reflected in its name, the project supports the growth of Passive House Regions in which “energy efficiency first” through Passive House is promoted, enabling remaining energy needs to be feasibly covered with on-site or nearby Renewable Energy sources. To do this, the project looks to regions such as Hanover, Brussels and Tyrol – front runner regions already actively and successfully supporting this approach. By investigating what makes the varied models these regions employ so successful as well as by making their successes more visible, the project aims to help other aspiring regions to become front runners themselves – taking, adapting and implementing best practice examples as well as the lessons learned throughout the project to facilitate the implementation of the EU’s 2010 Energy Performance of Buildings Directive on the basis of Passive House with renewable energy sources. proKlima take an active part as participant.

EU Project - CONCERTO Act2 (2006-2012)

Action of cities to mainstream energy efficient building and renewable energy systems across Europe.

Act2 is a 7-year long energy-related project (2006-2012) supported by the European Commission. It is part of the Concerto Initiative supervised by the DG Energy and Transport within the 6th Framework Research Programme.

Hannover and Nantes, as demonstration communities, in association with Koszalin, Malmö and Newcastle collaborate to apply at a district scale integrated concepts of energy provision, combining uses of renewable energy sources, energy efficiency technologies, rational energy use and innovative energy management (Read more about act2).

proKlima takes part as a workpackage leader.

EU Project - PEP (2005-2007)

Promotion of European Passive Houses

The objektive of the PEP project was to promote the potential of European Passive House concept in Europe by development of information packages and design tools for passive houses, the organization or (inter) national workshops, symposia and conferences and the set up of international passive house website.

proKlima took an active part as participant.

EU-Project - CEPHEUS (1998-2001)

CEPHEUS has tested and proven the viability of the Passive House concept at the European level. In Germany, Sweden, Austria, Switzerland and France, a total of 221 housing units in 14 building projects have been built to Passive House standards and are now occupied. The local settlement “Lummerlund” at Hanover-Kronsberg was part of the CEPHEUS project.

Stadtwerke Hannover AG / proKlima participated as contractor.
