The BIM4BIPV research project explores the possibility of implementing a consistent BIM planning flow for building-integrated photovoltaics (BIPV) in the interdisciplinary planning process. The Aim is to directly import open BIM-BIPV elements in architectural models and make them useable to determine solar energy yields, to calculate daylight exposure, for energy performance certificates and visual simulation.

 

Design and planning are interdisciplinary processes that require well-functioning data exchange via interfaces. For correct data transfer in design, visualization, daylight and PV simulation, electrical and energy system planning, profitability calculation, life cycle assessment, component and solar module production, BIPV elements must in the future be mapped as IFC objects in the sense of a uniform, open data format (OpenBIM). can be. This is not yet possible today.

The aim of the BIM4BIPV project is to research a consistent BIM planning flow for energetically optimized, building-integrated photovoltaics (BIPV), which at the same time generates solar energy, enables optimal use of daylight and provides shading. Against the background of climate change, this is becoming increasingly important for interior spaces as well as for urban open spaces and plantings.

Another goal of the project is to evaluate and generate BIM-IFC standards and innovative software solutions to make building-integrated photovoltaic building systems (BIPV) universally applicable, interactively plannable and usable.

The most important innovation of the BIM4BIPV project is its contribution to a 3-dimensional BIM building model with “active” integrated solar modules (BIPV / PV), which allows the integration of photovoltaic modules into the building envelope as early as the planning stage. This is not yet possible.

Using exemplary sample applications of BIPV in glass facades, roofing, solar roof and shading elements, it will be examined which interfaces, standards, tools and information are required to generate, plan, visualize, simulate, produce and communicate BIPV BIM elements to be able to hand over facility management and the material cycle.

The prototypes should ultimately be tested and optimized on sample plans.
