Nordic Built Active Roofs and Facades in Sustainable Renovation

The project has been running from 2014 to the end of 2017 and have been working with the Active House Alliance (www.activehouse.info), aiming to involve Nordic best practice producers and using the Active House Specifications in practice. Here the Finnish company ZED Consult will give a special input at the same time comparing to existing certification schemes like LEED, Bream and DGNB.


  • It is our belief that Active Roofs and Facades will be a new trend for the future and by realising testing of best practice solutions in all the 5 will lead to an improved aim to implement these solutions in practice.
  • The VTT organisation from Finland will work closely together with the large metallic roof and façade producer Ruukki in the project and it has been agreed that Ruukki will cover part of VTT’s costs in the project (with a Special focus on avoidance of cold bridges in constructions).
  • Monitoring and documentation work will be realised in a cooperation between VTT, Cenergia and the University of Iceland as the main partners, also using Active House Specifications.
  • Both innovative and best practice solutions will be full scale tested in cooperation with the housing association, KAB (DK), which will realise one of the 5 Nordic Built Challenge projects in practice and the WSP Group working with the housing company Trianon in Malmø, as basis of later implementation of sustainable renovation in Denmark and Sweden. A special focus on metallic roofs also for Denmark, where it is not used so much, but has benefits for solar panel integration. And innovative low cost glass-glass PV panels with a long service life will also be introduced in cooperation with the Danish company Gaia Solar.
  • Concepts of Active Roofs and Facades in connection to Smart Grid School Renovation will be implemented in cooperation with the city of Copenhagen and their large scale school renovation plan, which aims at renovation of all schools in connection to the Copenhagen Climate Plan, which aims at CO2 neutrality by 2025. A new approach will e.g. include combined use of solar thermal and PV as a “solar energy combined heat and power” solution, which can work in an ideal way together with the large combined heat and power (CHP) plants in e.g. Copenhagen.
  • The new decentralised heat recovery ventilation (HRV) solution developed for housing renovation by the Danish companies Øland and Ecovent will be full scale tested and documented. Innovative features that will be introduced are window integrated inlet of air, use of a new type of “automatic filter shift box” which only need to be exchanged every 10 years, and use of a new intelligent control device which allows for continuous registration of airflow and electricity use through the internet, which at the same time secures reading of the mean seasonal factor of performance (SFP) and general survey of operation.
  • As an alternative there will be a special focus on compact window integrated HRV solutions both for housing and schools. The benefit here will be much lower total costs due to the avoidance of large amounts of duct work, but the challenge include an optimised operation in correspondence with a minimum air exhaust possibility from wet rooms based on humidity sensors, and besides this handling of condensate from the used air in a way that does not create problems.
  • Norway the building renovation specialist company, Høyer Finseth, will work with full scale testing of best practice solutions and will at the same time work with the solar thermal panel producer AVENTA.
  • There will also be full scale testing of best practice solutions in Finland and Iceland.
