The single storey building with no basement is placed at the northern edge of the plot, so that it is open to the south and the garden area is sunny all day. Due to the buildings inclination to the road in the north, a space for the covered bicycle storage area and garbage area was created . The building is reached from the Robert Blum road. There is also the bus stop for the children to get in and out of the bus. The parking spaces for staff and visitors are located in the north. The main entrance is covered by a canopy from plywood board on steel pillars. The great entrance hall serves as an access o all the rooms.This hall has a skylight and a wind screen, an open wardrobe and covered terraces that serve as light source.
The group rooms are located on the south side of the building, the movement space (an extension of the hall) on the western side. In the north of the building are all adjoining rooms. The foundation plate is executed in reinforced concrete, the load-bearing walls and ceilings are made of plywood board. The internal partition is also made of plywood board or plasterboard. Interior walls are plastered with loam rendering.
In the lounges and in the hall acoustic ceilings are implemented. The roof is planted, so that together with the new planting there is around the same amount of vegetation after the construction is finished than it was before. The walls are insulated with rock wool and covered with larch planking. The flat roof is on EPS / XPS insulation and vegetated with generous green areas. The supply and disposal is provided via a groundwater heat pump, the public electricity and water supply through the public network. The rain water is made to percolate through dells on the site.
Building Equipment: The aeration of the whole building is controlled over an air conditioning appliance and equipped with a high heat recovery. The ventilation appliance is construed to the required hygienic demand of fresh air of the individuals and equipped with a heating and cooling register. That means, it assumes partially heat capacity and allows a preconditioning of the external air in summer. Air quantity calculation: 15m3/h per child and 25m3/h per adult. The residual heating takes place over heating surfaces, to be able to control the temperature in the group rooms individually. The building is heated by a ground-water heat-pump. A well-system with wellhead and infiltration well will be built. Additional heat is provided by the indoor solar collectors at the fanlight (31 m2 collectorc, 2690 l accumulator). The collector equipment covers a bigger part of the demand of warm water for the dishwashing- and washing machine (high demand because of day-handling), it is furthermore integrated in the heating system (central accumulator). 110 m² photovoltaic-elements with a capacity of 12kWp serve as porch in the south of the building.
