Glass placement and overhangs prevent solar gain during the summer.

Both increase overall cost, and the latter will reduce the amount of solar gain into the sunspace.

They can be used to increase direct solar gain when oriented towards the equator.

The Pennyland estate was laid out to take advantage of solar gain.

In the summer, shading devices eliminate all direct solar gain.

However, the primary need for central heating is at night and in winter when solar gain is lower.

It is heated by solar gain and internal gains from people.

This maximizes solar gain for heating and allows the entire building to be opened to the outside.

It is a low-energy building using the principle of solar gain.

These are therefore pointed towards the sun in order to minimize solar gain.
