Accurate Lighting Design Calculations at Your Fingertips

The heart of AGi32 is its unmatched calculation versatility with two powerful methods for precise photometric results. For exterior applications like parking lots or roadways, the lightning-fast direct-component engine produces point-by-point illuminance with full shadowing effects in seconds. For projects where reflected light matters, AGi32’s exclusive full radiosity engine (the only one in commercial lighting design software) computes complete light-surface interactions with sub-1% error margins. It’s able to calculate luminance levels, glare ratings, and daylight factors while automatically generating interactive light-accurate renderings. Switch between methods with a single click at any design stage, ensuring your virtual models accurately reflect real-world performance, meet strict compliance standards and reduce costly field adjustments.

Comprehensive Modeling Environment to Match Your Vision

AGi32 offers the flexibility to bring your lighting concepts to life through integrated 3D modeling tools that construct architectural spaces with ease- from simple rooms to complex geometries featuring vaults, domes and vertical extrusions. Designers can seamlessly integrate existing designs by importing 2D and 3D CAD drawings from AutoCAD (via DWG, DXF) or SketchUp (through our free LAI Data Exchange plugin) during import for accurate light interaction modeling. AGi32’s photometrically accurate rendering engine is fast enough for iterative visualization, allowing you to generate realistic color images and quickly test different lighting scenarios before fixtures are specified or installed to ensure your lighting design can be fully visualized and optimized in realistic architectural contexts

Harness the Power of Photometric Data

AGi32 empowers you with seamless access to comprehensive luminaire performance data in all global standard formats (IES, EULUMDAT, and CIBSE) that can be imported from anywhere on your network or dragged directly from manufacturer websites into your workspace. Connected to a robust photometric file network of 500+ brands pushing more than 100,000 files monthly, AGi32 gives professionals immediate access to reliable manufacturer data, reducing search time and ensuring projects use the latest and most accurate product information. The enhanced luminaire definition interface features a customizable multi-mode dialog with a powerful grid view for easy editing, automatic change submission, and streamlined management of all your lighting fixtures. This makes it faster to review extensive product libraries and adapt to your unique workflow preferences.

Generate Compelling Visuals and Detailed Reports

Deliver accurate data and professional presentations that win client approval with AGi32’s comprehensive output capabilities. Generate interactive renderings, illuminance and luminance maps, roadway optimizers, and compliance-ready reports that transform raw calculations into clear insights. Export calculations seamlessly to DWG or DXF for CAD integration. Run complete daylight studies across multiple days and hours in a single execution. Create high-resolution renderings or animated AVI movie files for dynamic presentations. The powerful AGi32 Reports function gives you complete control over professional output. Create branded master templates and populate custom layouts with calculation views, visualizations, and schedules. Finish with polished documentation via print or PDF that helps you communicate effectively with clients and meet regulatory demands while delivering projects on time and on budget.

AGi32 is the industry’s most trusted lighting design and calculation software, delivering unparalleled accuracy with its full radiosity engine and verified precision within ±2% illuminance and ±3% luminance.
