About E2ReBuild

The vision of E2ReBuild is to transform the retrofitting construction sector from the current craft and resource based construction towards an innovative, high-tech, energy efficient industrialised sector.

Today, the building industry in Europe is characterised mainly by on-site production, which may be inefficient with respect to cost and production time. Many hours are consumed in the construction process, where problems often are treated as unique and solved on-site. Furthermore, the sector is negatively associated with poor quality as well as an unsafe and unhealthy working environment. These problems are reasons why an industrial construction process for retrofitting is needed.

In E2Rebuild we adress these problems in order to speed up the development towards an energy efficient construction and building sector. Our aims are:

  • To investigate, promote and demonstrate cost effective and advanced energy efficient retrofit strategies that create added value for existing apartment buildings and endorse end-users to stay and build a dynamic society
  • To establish and demonstrate sustainable renovation solutions that will reduce the energy use to fulfil at least the national limit values for new buildings according to the applicable legislation based on the Energy Performance of Buildings Directives (for 2010) and to reduce the space heat use by about 75%.
  • To create a holistic industrialised process that aims to minimise technical and social disturbance for tenants and facilitates energy efficient operation and use of the buildings including encouraging energy efficient behaviour.


E2Rebuild is a collaborative project between eight European countries. Architect bureaues and construction- and housing companies as well as universities and research institutes participate in the project, which started in January 2011 and ends in June 2014.
