Every day people buy property and build homes without regard for the natural sunlight falling on their house. They could have taken into account the site's natural light and warmth (in winter) or shade (in summer) to make their house more comfortable and energy efficient. Not doing so can raise energy bills 30% higher than they need to be. Some people, interested in solar, even install expensive PV electric panels and never determine the best location with the most annual sunlight.
With just a little foresight, and without adding any additional expenses these people could have a house with bright, light-filled rooms — a house that is comfortable and appealing in winter and cool and shaded in the summer. Using the guidelines in this kit, and just a bit more planning, you can significantly reduce the lifetime energy use of your home and increase its comfort level well beyond that of nearby conventional houses.
