- Active Roofs and Facades in Sustainable Renovation
How do you create quality-assured standard solutions for sustainable renovation that has the ten principles from the Nordic Built Charter built into it, and at the same time lives up to the Active House specifications?
That question is what the participants of the project “Nordic Built – Active Roofs and Facades in Sustainable Renovation” will try to answer over the next three years. The project is a cooperation between Nordic partners within the field of sustainable innovation, and is funded by Nordic Innovation, EUDP, Energimyndigheten og Rannis.
Kick-off at Nordic Built Challenge winner site
The kick-off meeting took place at Ellebo, which is the case study of an EU project because of a forthcoming renovation project currently in the process of being accepted by different stakeholders. The renovation project is a result of the international Nordic Built Challenge competition which was won by the British architect Adam Khan out of a staggering 76 proposals.
The Ellebo housing unit is administrated by KAB – that is a part of the public housing sector in Denmark that actually is unique in the way it is organized. It is a common misunderstanding that the public housing in Denmark is owned by administration companies such as KAB or by the government – mostly because of the translation from Danish to English (den almene boligsektor – public housing sector).
The buildings of “den almene boligsektor” are collectively owned by the people who live in them and the decision making is made through “beboerdemokrati” (inhabitant democracy) and a yearly meeting between the inhabitants of the buildings is called “beboermøde”. The inhabitants of Ellebo has decided to go with the architectural proposal of Adam Khan. Read more about the project here and/or download the project booklet here.
The proposal consists generally of:
- Environmental improvement and energy efficiency
- Addition of attractive, modern family homes
- Overall esthetic update of buildings and green spaces
- Creating accessible units for disabled
One of the main aims of the project is to experiment with performance documentation, which currently is not being effectuated besides in Sweden. Experience from Sweden shows that performance documentation helps in creating more long-term solutions that actually delivers the promised savings on energy in sustainable building or renovation.
Besides this, the project will focus on full-scale testing, demonstration and follow-up concerning Active Roofs and Facades according to Active House specifications.
During the first day – the 19th of June - of the kick-off meeting the participants had several inputs concerning new and innovative ways of handling different functions of the building. For example, the IC-Meter that is able to measure temperature, humidity and CO2 levels in an apartment or the Ecovent installation - a decentralized ventilation system that only needs to have its filter changed every tenth year.
Exactly this combination of specialized people from different disciplines makes it possible to design an optimal solution when trying to make a standardized sustainable renovation that lives up to the Nordic Built Charter and the Active House specifications.
Afterwards the participants were invited inside the apartments of Ellebo to see the current condition of the building and to talk to the inhabitants about their perspective on the renovation project.
The second day of the kick-off meeting focused on giving inputs to the work ahead. The participants visited different sites and were presented to various innovative and architectural solutions. Some of which might well be incorporated into the design of a quality assured standard solution for sustainable renovation that has the ten principles from the Nordic Built Charter built into it, and at the same time lives up to the Active House specifications.
The project participants consist of Cenergia (DK), City of Copenhagen/Copenhagen Real Estate, KAB (DK), WSP Group (SE), VTT (FI), ZED Consulting (FI), University of Iceland (IS), AVENTA (NO), Høyer Finseth (NO), Ecovent (DK), Gate21 (DK) and FBBB (DK). The management team of the project consists of Cenergia, Gate21, KAB, WSP Group, VTT and Høyer Finseth.
