Renewable Energy Supply (RES) system in the Class1 CONCERTO-community. The RUE and REC technologies
are implement on a number of different building projects in the Municipality of Egedal both new building
projects and renovation projects. The building projects are described in detail in Deliverable 4 The
completed building projects and the Photovoltaic Systems (PV) are described in Deliverable 5 The
integrated RES supply system. Both reports can be downloaded from the Class1 website.
In this report the RUE and RES investments are first presented for each type of project the 2 new
dwellings projects, the two new institutions, the 2 energy renovated school, the 5 energy renovated
institutions and the 9 PV systems. Then the total investments are presented. In the final chapter the total
investments are held up against the total yearly economic savings and the simple payback time for the
entire project is found.
for the additional costs required to reach the Class1 energy target for new buildings which corresponded
first to the Danish Building Regulations (BR) 2008 low-energy class 1 definition and with Danish BR2010 to
the new low-energy class 2015 definition. As the actual additional costs for new buildings are very difficult /
impossible to achieve from the builders and constructors caused by the pricing structure in the building
industry. An example: The 65 new dwellings designated Passive Houses are so-called housing and even if
built as low-energy houses the contractor would (or could) not tell what the additional costs were. This also
was the case for the Kindergarten and the Centre for Elderly people. For some of the single family houses
the contractors did stipulate the additional costs, but they varied a lot from 5000 to 50.000 Euro per
house. These numbers in some cases also included the additional costs for the rainwater system that was
mandatory for all the houses in Stenloese South. The attempt to get a precise number for actual additional
costs therefore did not succeed. The additional costs presented here are therefore based on the so-called
eligible costs accepted as basis for the EU-support. Based on other experiences from low-energy building
construction this is judged as a fair assumption, maybe a bit on the low side for the single family houses,
but then on the high side for the other new buildings. The total cost and the additional energy investments
for the new buildings are presented in
