Development of building exterior shading and shading effects since ancient times been an important part of the building, now a beautiful coat glass wall into the mainstream of the building, because the glass surface heat resistance, heat transmission rate, indoor thermal conditions a tremendous impact, so shade especially energy-saving effect of building exterior shading played, has become increasingly prominent. Building where shading and building climate and geographical situation closely sunshine, sunshine and diurnal temperature changes exist, make the building interior needed shade in the afternoon, and sooner or later need to accept sunlight. Building shade not only block the sun, reduce air conditioning energy consumption in summer and winter to reduce heating energy consumption, but also has the use of natural daylight saving lighting energy consumption, improve indoor thermal comfort and visual comfort, adjust the ventilation and other multiple roles. The use of shading, air-conditioning electricity savings of about 25 percent, set a good shade of buildings can be improved exterior window insulation, energy-saving building heating by about 10%.
