The enhanced use of daylight in a
building is not simply a matter of installing larger windows, as these may
result in glare and overheating.
Instead the use of natural daylight seeks to optimise the entry and dispersal
of daylight in a building through the careful placing and sizing of windows,
the avoidance of deep plan buildings, and the use of atria, roof lights and
light décor to bring light into the hear of a building. Attention to planning, and the use of light
shelves, light guiding glazing, anidolic openings and prismatic panels to
reflect light deeper into the building, can assist further in reducing
independence on electric lighting.
These passive daylighting solutions are designed not to increase the
solar gain on the building.
