REAL-TIME SPATIAL DAYLIGHTING ANALYSIS FOR A 3D GEOMETRIC STRUCTURE

摘要

Various embodiments provide systems and methods enabling a user to receive feedback regarding a computer-implemented design of an architectural structure as the user is designing or otherwise modifying the computer-implemented design using a computer-aided design (CAD) software tool. The feedback (hereafter also referred to as “design feedback”) may provide the user with useful analysis information regarding the architectural structure's predicted characteristics (e.g., operational performance, resource consumption, cost, etc.) based on the current state of the computer-implemented design. In particular, daylighting analyses pertinent to the computer-implemented design of the architectural structure can be visually displayed to the user in real or near-real-time.

1. A method for real-time daylighting analysis of an architectural structure design, comprising:
receiving data specifying a geographical location for a three-dimensional architectural structure; computing a sky model for the geographical location to determine lighting contributions of a plurality of light sources for each of a plurality of permutations of dates, times and atmospheric conditions; performing daylighting analysis, in real-time or near real-time, on the three-dimensional architectural structure using values of the computed sky model, the performance of the daylighting analysis comprising computing at least one of spatial daylight autonomy and glare for the light sources on work spaces defined in the three-dimensional architectural structure by applying the values of the computed sky model to the three-dimensional architectural structure; displaying to a user a graphical representation of the at least one of spatial daylight autonomy and glare, wherein the displaying comprises rendering increasingly discretized representations of the at least one of spatial daylight autonomy and glare for the three-dimensional architectural structure.
