Lighting Analysts ElumTools

Lighting Analysts ElumTools is the industry-leading lighting analysis add-in for Autodesk Revit, enabling designers and engineers to perform accurate, illuminance-based calculations directly inside the BIM environment. Unlike external lighting software that requires tedious import/export, ElumTools works natively with Revit families, rooms, and materials – eliminating translation errors and preserving design intent. Version 2026.5.0.3 continues Lighting Analysts’ legacy of bringing rigorous photometric science to the Revit platform, offering full support for IES/LDT photometric files, point-by-point calculations, daylight integration, and LEED/energy compliance reporting. Whether designing interior office lighting, sports field illumination, or façade accent lighting, ElumTools delivers the accuracy, efficiency, and BIM integration that modern lighting design demands.

⚡ Key Features & Capabilities

???? Native Revit Photometric Analysis

Illuminance Calculations:

  • Point-by-point illuminance (horizontal, vertical, inclined)

  • Average, maximum, minimum, uniformity (Eavg / Emin)

  • Glare (UGR, DGI, VCP) – optional modules

Calculation Methods:

  • Ray tracing (photon mapping) with inter‑reflections (walls, ceiling, floor)

  • Daylight coefficient method for dynamic skies (sun, overcast, partly cloudy)

???? Revit Family & Material Integration

Light Sources:

  • Native Revit lighting fixtures (works directly – no export)

  • IES/LDT photometric web files (drag‑drop into family)

  • Luminous flux, candela distribution, color temperature (CCT)

Materials:

  • Revit material reflectance, transmittance, color

  • Glazing (clear, tinted, frosted) for sunlight penetration

???? Daylighting & Climate Data

  • Sun position (date, time, location – project address)

  • Sky model: CIE overcast / clear / partly cloudy, Perez all‑weather

  • Daylight factor (DF) & annual daylight autonomy (DA)

???? Calculation Grids & Reporting

Grid Placement:

  • Workplane (desk, floor, counter, task)

  • User‑defined X/Y spacing, rotation, multiple rooms

Reports:

  • Illuminance contour plots (pseudocolor within Revit view)

  • Schedule: point‑by‑point values (Excel/CSV export)

  • LEED v4.1 EQc7 (lighting quality) & Energy Model integration

⚡ Energy Model Link

  • Transfer illuminance results to gbXML for energy simulation

  • Lighting Power Density (LPD) – automatic from fixture wattage

???? What’s New in Version 2026.5.0.3

  • Revit 2026 Support – Full native integration for Revit 2026 LTS
