What is the light distance between the house and the house? How is that stipulated?
Stone dolls, 1:1.2 is not absolute, due to latitude in different parts of our country, the sunshine coefficient is different. Hangzhou, for example, is 1:1.2 here, but Shenyang is around 1:1.80~1.9. The following explanation is true. Landlord, you are mainly in what city, and then check the sunshine coefficient, and if the local sunshine coefficient can not be found, you can check the same latitude latitude of the city's sunshine coefficient as a reference. Then according to (the cornice under a layer of residential window height): Housing spacing = sunshine spacing ratio can be.
There are two main floor space: 1, sunshine spacing in the winter solstice full window sunshine hour as a standard; 2, fire spacing, in accordance with the architectural fireproof grade and different height and not one; the two meet, the general visual space, ventilation distance can meet together. According to the criteria established by the Ministry of construction, the house interior space height shall be not less than 2.40M, the distance between each building is not less than 0.70 of the building height multiplied by the coefficient, if less than this distance, it will affect between the indoor lighting and ventilation and residents life depends on what your place?
Distance between high-rise buildings, national standards, you can refer to the following calculation methodsFloor spacing =1:1.2 ratio calculation.China's national standard "People's Republic of China city residential district planning and design specification (GB50180-93)" (hereinafter referred to as "standard") provides: "big city residential Insolation Standard for 2 hours on it over, the winter solstice is more than 1 hours, the elderly residential buildings should not be less than 2 hours of sunshine in the winter solstice standard; any facilities should not be increased the adjacent residential sunshine in the original design standard to reduce the original building; urban transformation projects of new residential Insolation Standard may decrease, but it should not be less than 1 hours of sunshine on the standard." In accordance with the provisions of the state (design specifications), the winter solstice sunshine time is not less than 1 hours (the bottom of the house window) as standard. With the height of /tan spacing is outside the building to house the cornice Ping (a) during the winter solstice at noon the sun altitude angle around a-.
