Active Roofs and Facades
Cenergia
Peder Vejsig Pedersen, director of Cenergia, outlines the agenda for the Nordic Built project Active Roof and Facades in Sustainable Renovation.
The Nordic Built Active Roofs and Facades project is supported by Nordic Innovation, allowing strong development of leading Nordic competences in the area of building renovation. This is achieved by creating transnational public private partnership models to support the development towards near zero-energy building solutions and associated performance documentation – which is required in the EU building directive.
The proposed co-operation with the building industry on developing models and the demonstration of Active House-based sustainable renovation will create a strong Nordic alliance.
The project runs from 2014 to 2017 and will involve companies which are represented in the Nordic countries and companies from the international Active House Alliance (www.activehouse.info).
Main features of the work plan
To work alongside the Active House Alliance, aiming to involve Nordic best practice producers and use the Active House Specifications in practice.
Here, the Finnish company ZED Consult will give a special input whilst at the same time comparing existing certification schemes like LEED, Bream and DGNB.
The VTT organisation from Finland will work closely with the large metallic roof and facade producer Ruukki in the project. There will be a special focus on avoidance of cold bridges in constructions.
Monitoring and documentation work will be realised in a co-operation 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 co-operation with the housing association KAB (DK), which will realise one of the five Nordic Built Challenge projects in practice with the winning entry by architect Adam Khan from London, and the WSP Group working with the housing company Trianon in Malmø, as the basis of later implementing sustainable renovation in Denmark and Sweden.
Concepts of Active Roofs and Facades in connection to smart grid school renovation will be implemented in co-operation with the city of Copenhagen and their large scale school renovation plan. The plan aims at renovation of all schools in connection to the Copenhagen Climate Plan, which aims at CO2 neutrality by 2025.
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 a window integrated inlet of air, use of a new type of ‘automatic filter shift box’ which only needs to be exchanged every ten years, and use of a new intelligent control device which allows for continuous registration of airflow and electricity use through the internet.
And as an alternative there will be a special focus on compact window integrated HRV solutions for both housing and schools. The benefit here will be much lower total costs due to the avoidance of large amounts of duct work.
In 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, here working with VTT, Demos and the University of Iceland.
Background of Nordic Built Active Roofs and Facades in Sustainable Renovation
Co-ordinated by the Danish energy specialist company Cenergia, the project will utilise the results of the recently finalised EU-Concerto project Green Solar Cities (www.greensolarcities.com). These results will be presented in a book by Routledge/Earthscan, available from 29 January 2015. See http://www.routledge.com/books/details/9780415731195/
The main results from Copenhagen are illustrated in the two small videos below:
