[edit] 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

The VELUX Daylight Visualizer is a professional simulation tool created to empower architectural design with critical and validated daylight level analysis. Optimizing the amount of natural light that is available in a building means less electric lighting is required during the day. Daylight simulation plays an active role in supporting a commercial building’s compliance and user needs by providing critical overviews of building performance.
The VELUX Daylight Visualizer delivers project certainty when measuring and calculating critical daylight factors. Exploring complex design spaces enables you to see daylight levels in high-resolution and 3D form, giving more design clarity with enhanced knowledge of a building space, and the role daylight plays in transforming an environment
This digital tool allows you to simulate daylight scenarios with quantifiable accuracy at the concept stages of building design. Explore and accurately predict daylight levels in building projects to ensure they meet specific daylighting requirements.
