Elementary school gym Körperich

The gymnasium of the elementary school in Körperich was built in 1971 as a solid construction and is one of the 25 percent worst-performing buildings in Germany in terms of energy efficiency ("worst-performing building") according to the standards of 1971. The energy-efficient refurbishment of the gymnasium is therefore a contribution by the municipality of Südeifel to the transformation of the building stock towards the goal of climate neutrality by 2045. Due to the best possible insulation of the building envelope in economic terms, the primary energy requirement will be reduced by 94% (achieving KfW Energy Efficiency Building 40). The floors will also be refurbished and underfloor heating and LowEx technology implemented. The calculated heating output of the air-to-water heat pump is 23.3 kW. The photovoltaic system (approx. 25 kWp) supplies electricity for heating and hot water and is a component of the planned electricity balancing circuit model for balancing the electricity consumption and generation of all properties in the South Eifel municipality.

The project is characterized by the following points:

• Existing pollutants are dismantled and disposed of professionally (e.g. the asbestos-containing façade cladding)
• The "serial refurbishment" (use of prefabricated façade elements away from the construction site) enables the refurbishment to be implemented in the best possible way to suit school operations.
• Reduction of the effects of climate change (summer heat insulation) and promotion of biodiversity through extensive greening of the new flat roof on the changing room wing.
• Circular construction: True to the motto "we build with what's there", as much (uncontaminated) building material from the existing building is recycled as possible. For example, the standing seam cladding of the roof of the changing room wing will later be used to clad the changing room wing. The wood from the dismantled pitched roof of the changing room wing will be used to construct the insulating façade.
• The building materials used are largely made from renewable raw materials from the region.
