To a certain extent, this extended framework makes it possible to offset the performance of the building’s heating system against its structural thermal insulation in the overall energy equation. Independently of these, the maximum thermal transmittance values measured in must be met by all components of the building envelope. This is done using a primary energy factor in the building’s energy equation. Secondly, the energy demand is evaluated in terms of primary energy consumption by including the losses arising in the generation, transformation and transportation of the respective energy carrier. Consequently, the final energy transferred to the limits of the building is the relevant value rather than the useful energy available in the room. The merger of the German ordinances relating to heating systems and thermal insulation into one joint ordinance extended the existing reporting framework in two ways: Firstly, by integrating the aspect of the heating technology into the energy equation, the new ordinance also takes account of losses arising during the generation, distribution, storage and transfer of heat. Increasing the thickness of insulation also significantly reduces heat losses due to thermal bridging of the substructures. by using alternative materials, reducing the contact surface of the brackets on the wall and re- ducing the average number of brackets used per m². The heat losses caused by the brackets can be reduced, e.g. These heat losses are taken into account using the thermal bridge coefficient. Here, the metal brackets act like „cooling fins“ breaking through the insulation and causing additional heat loss. In the case of VCWs with metal substructures, the energy loss through the external wall can be up to 30% higher due to the thermal bridge effect of the bracket construction and depends on the number of anchor points as well as the design and material used for the substructure (aluminium substructure / normal thermal insulation requirements). This takes into account not only the primary energy consumption required to heat the building but also the transfer of heat through the external wall. The German ordinances relating to heating systems and thermal insulation require the production of a thermal insulation certificate to record a building‘s energy efficiency.
