Utilising daylight in buildings is an important technique for both reducing energy use and providing a comfortable, more natural environment for the occupants
Designing for daylight involves a number of steps
- First the site and the building form must be assessed for the availability of daylight. This is particularly important in a built up area. If access to daylight is poor then there is little point in attempting to design for daylight: glazing ratios would need to be very large and this may make controlling other environmental factors very difficult.
- If access is OK then window sizes and positions will influence the quantity and distribution of daylight, these need to be determined.
- Finally the more specific details of the interior geometry and surfaces will be influencial, these are best determined using computer aided techniques.
