Daylight calculations are typically conducted using advanced modelling tools such as Design Builder or other simulation software. These tools evaluate factors like daylight factor, illuminance levels, and glare potential, providing precise insights to optimise natural light within building spaces.

No, daylight calculations are not mandatory for all developments. However, they are often required for planning approval in residential and commercial projects, particularly in densely built-up areas or when local authorities specify natural lighting standards. They are also valuable for projects targeting sustainability certifications.

Illuminance mapping evaluates the distribution of natural light within a space, highlighting areas with adequate, insufficient, or excessive lighting. This analysis informs design decisions, such as window placement, glazing type, and room layout, ensuring balanced and functional lighting throughout the building.

Yes, daylight factor calculations play a critical role in enhancing occupant wellbeing. Adequate natural light has been proven to improve mood, productivity, and overall health while reducing eye strain and fatigue. Properly lit spaces also create a more pleasant and inviting indoor environment.

Seasonal variations in natural light are addressed through simulation tools that account for changing sun angles, daylight hours, and weather conditions. These models provide comprehensive data to ensure the building design performs well under varying conditions, delivering consistent daylight access year-round.
