Description
The present paper investigated the application of the daylighting analysis features of the Insight BIM plugin, comparatively to DIVA, a plugin for a 3D Nurbs modeling software. Considering the early phases of the design process, workflows, simulation results and processing times were analyzed, focusing on the prediction of static (illuminance level) and dynamic (sDA300,50%) metrics. Simulations on both tools were performed in the context of analyzing the daylight behavior in a deep office room model, with and without light shelves. Results indicate that Insight has limitations compared to DIVA, especially concerning input data configuration flexibility. Simulation results presented significant similarity between Insight and DIVA in most cases, being the direct sun case the one in which illuminance levels differed the most. Insight presented longer processing time for the static metric and similar average time for the dynamic metric. Work findings indicate that Insight has important potential to contribute to daylighting analysis on early phases of design process, and points out to barriers to its adoption and correct use. Authors expect this paper to benefit architects, engineers and students on the comprehension of both tools.
