BIM4BIPV - Future aspects of building-integrated photovoltaics (BIPV) in cross-system BIM planning

Research into an end-to-end BIM planning flow for energy-optimised, building-integrated photovoltaics (BIPV) that simultaneously generates solar energy, enables optimal use of daylight and provides shading.

Short Description

Status

ongoing

Motivation

Design and planning are interdisciplinary processes that require a well-functioning data exchange via interfaces. Therefore, in the future it must also be possible to map building-integrated photovoltaic elements (BIPV) as IFC objects in the sense of a uniform, open data format (OpenBIM) in order to then be available for correct data transfer in design, visualisation, daylighting simulation, photovoltaic system simulation, electrical planning, energy system planning, economic efficiency calculation, life cycle assessment, component and solar module production. This is not possible today.

Contents and goals

The aim of the BIM4BIPV project is to research a continuous BIM planning flow for energetically optimised, building-integrated photovoltaics (BIPV) that simultaneously generates solar energy, enables optimal use of daylight and provides shading. This is becoming increasingly important against the backdrop of climate change, both for interior spaces and for urban open spaces and plantings.

Another goal of the BIM4BIPV project is the evaluation and generation of BIM-IFC standards such as BIMQ and innovative software solutions to make building-integrated photovoltaic (BIPV) building systems universally applicable, interactively plannable and usable.

Methods

Using the example of exemplary sample applications of BIPV in glass facades, roofing, solar roof and shading elements, the project will investigate which interfaces, standards, tools and information are required to generate BIPV-BIM-elements, plan them in a multidisciplinary manner, visualise them, simulate them, produce them and transfer them to facility management or the material cycle. Finally, the prototypes are to be tested and optimised on sample plans.

Expected results

The most essential 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 cross-system planning process of integrating photovoltaic modules into the building envelope. This has not been possible until now.
