The brochure of the German federal Ministry for Transport, Building and Urban Development explains the definition and describes the calculation method for an efficiency house plus.
Based on intensive research and development efforts of the building and building service system industry it has been possible, since a few years back, to create energy concepts for new buildings that no longer use fossil fuels but instead to generate excess energy and feed it into the electricity grid. The balance between used and generated energy is made in an annual way. The efficiency house plus allows innovative partners from the building industry to transfer their pioneering spirit into the building practice and thus show their market leadership. The efficiency house plus is the sustainable answer of the building industry to the challenges of our current and future generations.
Apart from the explanation of the definition and the calculation method, modular concepts and key parameters for an efficiency house plus are described. Different variants to achieve the energy surplus level are applied and presented as an exemplary building. Another chapter shows already realised case studies.
The brochure is available in the German language.
