CLASS1 Site Stenløse
Stenløse - a town in Northern Zealand – is part of Egedal Municipality. Egedal has decided to strengthen the energy requirements for a new settlement to be erected. More than 400 dwellings, a kindergarten and an activity centre for elderly people will be designed and constructed with a heating energy consumption and an overall primary energy consumption better than it is required for a low energy class 1 building according to the Danish Building regulation from 2008 (BR08) which is close to low energy class 2015 in the newest Danish Building Regulation.
In the years 2007-2012 a total of 442 dwellings were planned be designed and constructed with a heating demand corresponding to the Danish low-energy standard referred to as "BR08-low-energy class 1" in a new settlement called Stenløse Syd. This means that the energy consumption will be 50% below that required by the energy regulations. 65 dwellings will be designed and constructed with a yearly heating demand of 15 kWh/m². Furthermore the Concerto community includes a kindergarten and an activity centre for elderly people.
Due to the financial crisis a significant slowdown of sales of the building plots caused the fact that the project could not be completed within the scheduled timeframe. A contin-gency plan has therefore been developed and implemented. The contingency plan increases the CONCERTO community to include the existing part of Stenloese City, where public buildings (two schools, and three kindergartens, a Support and Activity Centre for Mentally Ill and a so-called “after school-center are to be renovated to reach the Danish BR08 energy requirements for new buildings. In addition to this a large area of Solar Cells (PV) will be installed on different municipal public buildings.
As a Concerto project is to demonstrate a balanced introduction of energy saving and renewable energy supply it was important to keep both the energy conservation and renewable energy supply within the project. In the contingency plan the energy saving of – primarily – dense low-rise housing is replaced by the energy renovation of the municipal public buildings and the renewable energy supply from the biomass CHP plant is instead contributed from the total area of PV systems (514 kWp).
Demonstration that energy refurbishment of existing public buildings to the level of energy requirements for new buildings in the Danish building regulations is a viable approach. Egedal will be a frontrunner in developing an energy retrofitting strategy for the whole public building stock which will be useful to many other European local authorities.
Demonstration the viability of large scale PV installation on existing public buildings. The use of existing roofs poses a challenge with respect to considerations for the strength of the construction, the correct orientation and planned maintenance of the roofs. The experience from this work will also be useful to many European municipalities.
The buildings will be supplied by a combination of heat pumps, solar heating systems and PV systems
