Use of solar buildings, continue to emerge, both beautiful and practical. A passive solar house, the sunny side of the wall is black, wall mounted sealed glass frame to make it with the form a channel-like space between the exterior wall. Sun to sun heat the air in the channel, the hot air rises from the top of the valve into the interior, the indoor cold air heating but also by the lower part of the air vents into the channel, this endless cycle, room temperature continuously improve. Summer, as long as the top of the valve is opened to the outside, the hot air flows to the outside to go, so houses north of the colder air constantly into the interior, and reserve outflow of hot air at room temperature followed the decline. This sun room, as long as there is good insulation materials, design reasonable, will be able to receive a cool effect. Solar water heater collector box, the principle of the structure are similar, they are mostly installed on the roof, to add to the splendor of modern architecture. Recently abroad and the development of a new type of glass tile, its main raw material is silicon. The tile itself is solar energy storage device, it is not only in the sun to produce electric current can be generated even in rainy weather, the current can be used for indoor lighting.
