The growth of BIM (Building Information Modeling) software is exploding and in many architectural design and engineering firms, it is almost completely replacing CAD software for the purposes of architectural and building system design. To date, the industry standard illumination design software programs lack the ability to easily exchange information with models in the BIM environment. The reason for this is two-fold; current illumination software utilizes a complete environment approach to the calculation of illuminance which is burdened by the large size of the BIM model, and the complexity of exported geometry from BIM is beyond the needs of practical calculation of workplane or surface illuminance. With today’s illumination design software not getting the job done, there remains a need to quickly compute basic illuminance from electric and daylight sources within individual environments in a BIM model, and tabulate the results in a way consistent with the behavior of the BIM software.
ElumTools is a calculation Add-in used to predict the performance of electric lighting systems and daylight within the Autodesk® Revit® Architecture or MEP software. With ElumTools the need to utilize external software to compute illuminance from light sources placed in Revit is no longer necessary.
