Abstract

Parametric design tools are digital tools used by the architect, for the purpose of creativity. BIM platforms tend to simplify the work of designers and engineers, if their products are within standards. Within the digital construction field, creativity and information modelling are frequently in contrast. An interaction between parametric design and BIM platforms is necessary to avoid the influence of predefined parametric elements on the design concept. Parallel origami is suggested as a generative tool to produce complex shapes. This research proposes a new tool for Revit architecture software (BIM tool), based on the BIM-Parametric-Origami (BimPO) integration framework. This tool directly generates optimized alternatives of complex or non-conventional solar devices, for specific target performances of building envelopes. The BimPO script provides more possibilities for an increasing number of form generation. Results will prove BimPO’s ability to efficiently achieve numerous Origamic Solar Device (OSD) alternatives, for improved energy efficiency. Moreover, selection criteria are proposed, which could indicate optimal OSD configurations, with a balance of daylight and thermal performance (TH), based on daylight simulation.
