Einfluss der Bauwerkintegrierten Photovoltaik in Fassaden bei der energetischen Bilanzierung von Gebäuden (Teil 1): Potenzial der Fassadenintegration von Photovoltaik

摘要

Influence of building�integrated photovoltaics in fa?ades for the energetic evaluation of buildings. Part 1: Potential of fa?ade integration of photovoltaics. In the framework of the realization of the Paris Agreement, the Federal Government aims for a nearly climate�eutral building stock by 2050. Apart from the prevention of energy loss, the production and consumption of energy from renewables in the close proximity to the building are immensely important. Photovoltaics (PV) offer a considerable potential by converting a part of solar power into electrical energy. The so far preferred orientation of PV on the surface of roofs does not generate enough energy to cover the primary energy demand of a building. Fa?ades offer a great capacity potential. This contribution describes the constructive, normative and energetic peculiarities of energy production at fa?ades with building�integrated PV modules and discusses these in the scope of own consumption. In Part 2, the operating behavior of building�integrated PV fa?ades will be examined in detail by applying free field measurement and recommendations will be given regarding normative considerations.
