Windows can be coated with an absorptive or reflective film
to reduce the amount of light transmitted into a
house/office. This is great for keeping your house cool in
summer, but will also keep your house cold in winter.
What is needed is a window that reflects summer sunlight
My solution is to make windows of relatively high refractive
index glass and coat the outside with an anti-reflective
layer. Light entering from high/shallow angles (summer
sunlight) will travel through the anti-reflective coating and
then be reflected (by 'total internal reflection') from the
inside face of the window. Light entering from a low angle
(winter sunlight) will go straight through without
