Integrated daylight modelling
with Radiance accuracy

Better Building's daylight workflow combines simplicity and technical rigour. Run daylight factor or climate-based simulations using the Radiance engine, with tools to define grids, sky models, shading, and surface reflectance. Designed for clarity and speed, users can assess performance at zone or whole-building level, adjust inputs easily, and export high-quality results for collaboration or verification.

Radiance-Powered Simulations

Utilise the open-source Radiance engine for accurate daylight factor and climate-based daylight modelling simulations.

Flexible Grid Configuration

Define working plane heights, grid sizes, and margins to tailor the simulation grid to specific project requirements.
