Q:How about this apartment? Is it practical? Will the living room be too long for lighting?
Huxing quite wrong, do not know how to face?
Q:Southeast, southwest, which daylighting good?
Southeast well, sunshine southeast and southwest are similar, southwest Xishai sun bigger. But you have to consider that our basic spring blowing wind, Southeast for ventilation. Southwest? In winter, blow the west wind and the northwest wind a little bit more. Your window won't open.
Q:Balcony living room together, West, morning lighting will not be good?
There will be some. It should start very well at half past noon in the West
Q:Floor spacing and lighting, as well as the volume rate problems
Floor spacing: the distance between the exterior walls of the adjacent buildings. The distance between two adjacent buildings and buildings in the same district. The control of building spacing is to ensure the quality and safety of people's work and life, and to meet the requirements of the necessary sunshine hours, lighting, ventilation, sound insulation and so on.Floor space (before and after) according to the calculation of sunshine spacing, the so-called sunshine spacing: two rows around South between the buildings, while maintaining the minimum distance to ensure the rear housing in the winter solstice bottom not less than one hour full window sunshine.Calculation method of the interval: to Xiangyang housing long edge, Chaoyang to the south, at noon sun back to the basement window based on calculation.
Q:How is daylight rate calculated?
The calculation method of lighting rate mainly includes the calculation of indoor natural illumination according to the size, quantity and location of the window, or the required window area according to the daylight factor prescribed by the daylighting standard. In addition, there are glare calculations. In order to simplify the calculation, an ideal standard sky brightness distribution is usually defined as the calculation condition. Most of the countries in China and in the world use the cloudy sky brightness distribution as the standard light source for lighting calculation.There are ten kinds of lighting calculation methods published all over the world. These methods are mainly based on two different bases which are derived from photometric theory and measured data based on daylight model experiment. The forms of expression include graph method, number solution method and tool method.
Q:What inspection batch does the lighting top belong to in the construction project?
Skylight glass curtain wall skeleton do covert batch inspection
Q:What does the house mean by daylight? What's the sun's use in the house?
Lighting and ventilation are issues that must be taken into consideration when buying a house. Say "daylighting" means the time and area of the sun's light shining into the room. The length of time and area are large, which indicates the good lighting. At least ensure that the living room, the main bedroom lighting better. Bad lighting can make the room Yin, bacteria, body easy to mildew, adverse to health.
Q:Building lighting problems. North and South are 18 floors. How about the 5 floor lighting?
Our country is in the northern hemisphere, the winter solstice is the shortest time of sunshine, for example to calculate noon sunshine, a formula: L=H-dtgAL: the shadow height from the front floor; H: the height of the front building; A: the altitude of the sun at the solstice; D; floor spacing.Ma'anshan is 31.7 degrees north latitude, the winter solstice noon solar altitude is 90-23.5-31.7=34.8 degrees, three meters by layer 18 floor 54 meters high, is the winter solstice before the shadow building height of =54-45xtg34.8=22.72 meters. That is to say, the day after the winter solstice 7 floor below noon to see the sunlight.As for the left front, that is, the southeast of the 6 storey building on the East after the impact of the floor, the next can not give accurate formula. But the winter solstice day the sun rises in the southeast, the six floor certainly light. You said the 5 floor of the east of the lighting will certainly not be good.
Q:How can the concert hall be light?
Artificial lighting, no windows. If there is a window (but not), it will have a serious impact on acoustic design.
Q:Please help me to see if this large deep into the balcony will affect the living room lighting, Southeast house, as well as the overall Huxing?
The house, no matter how it was, came over to see it.. Dude, tell the truth, when the house died, if not buy, advise you to choose another... Recommend you choose a north-south transparent house, you look like this house is about 85-90 square meters of high-level.. Recommend you pick a different one.. In general, this area of the house should be North and South: South living room + bedroom, north bedroom + kitchen + restaurant, North and south bedroom, the middle of the toilet.
