Passive Solar Heating

By taking advantage of passive solar heating, you can cut your energy bills in the winter. The trick is to allow the sun to warm your house for you.

The sun drops towards the southern horizon in the winter, so you'll need to give it a clear view of the south side of your house. As the sun beats on the walls, it will warm the house. Having a tile, concrete, or stone floor can help store the solar energy that streams in through the windows.

But in the summer, passive solar heating can work against us here in Florida by driving up our cooling bills. Planting deciduous trees along the west side of your property will help block the hot afternoon sun from heating your house.
