How to predict daylight conditions in buildings during the design phase

The importance of predicting daylight conditions prior to design realisation
The quality of natural light within a building is an important consideration for designers.
Daylight has been shown to be an important factor for the health and wellbeing of building users. Contributing to both human comfort and productivity. It also provides appropriate illumination to carry out tasks and gives people a connection with the outdoors.
Being able to predict a building’s daylight conditions at the design stage will avoid costly changes downstream and gives the confidence that the building design will:
- Meet any specifications and standards for daylight e.g. EN 17037
- Minimise the need for artificial lighting
Using the VELUX Daylight Visualizer to predict daylight conditions in buildings

VELUX Daylight Visualizer is a free professional simulation tool for the analysis of daylight conditions in buildings.
Utilising this software tool, design professionals can predict and document daylight levels and appearance of a space prior to realisation of the building design.
Daylight Visualizer can:
- Accurately simulate and quantify daylight levels in interiors
- Calculate daylight factor levels
- Evaluate requirements for daylight provisions in the new European Standard for Daylight in Buildings - EN 17037
- Create or import 3D models
- Perform luminance and illuminance simulations under different CIE (The International Commission on Illumination - the Commission Internationale de l´Eclairage) sky conditions
