Passive Solar

Passive solar is a type of energy. Passive solar is the use of sunlight for useful energy without the use of active mechanical systems such as a furnace or air conditioner/swamp-cooler. These technologies convert sunlight into usable heat for the air in your home to keep it warm during the winter months and cool during the summer months.  This includes direct and indirect solar gain for many things and to name a few there is space heating and water heating. In the picture it shows a tree for shade and protection against wind and also will help reduce water evaporation. If the roof has a hang over it also helps keep the house shaded to keep the summer sun out and the cool air in. If you have heated insulation the windows will help keep the warmth in from the winter sun and keep the house at a comfortable temperature.
