This single family home in Bad Rothenfelde is based entirely on a consistently ecological concept. All of the construction materials are either re-growing sustainable options or raw materials that raise no construction biological concerns. A heat pump will eventually provide the heating energy for the entire building. However, given that at the time of construction heat pump technology still had not been tested, a wood pellet stove was used to complement the pump solution. Most of the roof provides the support surface for solar collectors, while the remaining surface has been covered with greenery. The microclimate created by this arrangement under the generously roof covered outdoor areas ensures that the temperature is comfortable inside the house year-round.

GREEN ROOF ZONE VEGETATION

In addition to the installation of solar panels, green plants just like the surface of the roof pointing north cover the southern part of the roof. Over time, nature has allowed two completely different types of vegetation to flourish on both sides of the roof, which harmonize ideally with the construction technical requirements.

On the south end of the roof, a sedum herb dry vegetation space has sprouted up, which absorbs the heat of the sun year-round. The vegetation on the north side of the roof provides a solid green cover that provides increased heat insulation throughout the year and helps reduce the heat outflow from the building.
