From May to August Direct sunlight should be allowed inside the building to warm exposed walls andfloor.

The rest of the year it is best to block out direct sunlight so that the building does not heat up when it is already warm outside.

The Summer Courtyard opens up to the east, allowing morning light to warm the space during the winter. The center itself blocks all evening light which will keep the center cool during the summer, whilealsoallowingambientlighttoinfiltratetheinterior.
