Benefits for Office Building
Well-designed sun control and shading
devices can dramatically reduce
building peak heat gain and cooling
requirements and improve the natural
lighting quality of building interiors.
Proper glare control may even reduce
the energy consumption by 5-15%. In
electric lighting design, it is beneficial
to have the right amount of light with
appropriate limits to glare. This can
reduce the number of light fittings
and lower the initial capital cost and
operational costs in the long run.
