Researchers at the University of Hanover want to optimize BIPV

Roof surfaces covered with photovoltaic systems are not sufficient to meet energy needs, especially in non-residential buildings. »However, since surface mounting on the facade is critically classified in terms of aesthetics as well as planning and installation, facade surfaces often remain unused,« explains Katharina Klemt-Albert, head of the Institute for Construction Management and Digital Building at Leibniz Universität Hannover (LUH).
Together with her team and eight partners from industry and science, she wants to optimize the life cycle of building-integrated photovoltaic systems (BIPV) in a newly launched project, from planning to installation and operation. The aim is to increase the acceptance and application of BIPV. In addition, visually appealing photovoltaic surfaces will aesthetically enhance facades.
A façade area of the Danish Expo Pavilion at the Hanover Exhibition Grounds will serve as the demonstration building. There, data is collected over the entire life cycle of a BIPV system and processed in the XLAB digital laboratory for a digital counterpart. The researchers will then simulate and analyze the practicality of BIPV systems. The results will be compiled in a practical guide, supplemented by a digital platform that maps the processes and information in the life cycle of the model.
Participants in the project include the Institute for Solar Energy Research (ISFH), the Bavarian Center for Applied Energy Research, the bifa Environmental Institute, the engineering services provider Albert, the architectural firm Lang Hugger Rampp, the BIPV system manufacturer Blue Energy Systems, and the energy management system developer nD-Enerserve. The planning office Carsten Grobe Passivhaus is providing the demonstration building on the exhibition grounds in Hanover for the research.
The German Federal Ministry for Economic Affairs and Energy is funding the joint project »BIMPV - Retrospective BIM approach for lifecycle-optimized integration of BIPV systems in the building envelope« for three years with €2.4 million ($2.9 million).
