The orientation of the house is determined by the longitudinal axis of the building. Generally speaking, the vertical line of the back wall of a house is sitting, and the other end of this vertical line is sitting. Sitting orientation includes sitting orientation of the house and sitting orientation of the door. The door and the house sit in the same direction, but there are also differences.
Houses facing east and west are geomantic omen. Weaknesses of houses facing west: in summer, people usually have several air conditioners in decoration, which can alleviate the suffering of western sunshine, and rooms facing east or west are easily destroyed by light.
Because in a room facing east or west, the fierce sunshine in the morning or afternoon will lead to excessive light in the bedroom, stimulate nerves, affect rest, lead to insomnia, and even make people become angular, impulsive and irritable. If the window is large, the impact will be more serious. If you have lived in a room facing east or west and it is impossible to change it for the time being, then pay attention to closing the curtains at the right time.
The disadvantages of east-west direction
The orientation of the building has an influence on the heat radiated by the sun in winter, the heat permeated by the air in summer and the ventilation and cooling. Other things being equal, the heat transfer and heat consumption of east-west slab multi-storey residential buildings are about 5% higher than that of north-south slab multi-storey residential buildings.
The energy consumption of air conditioners or the cost of shading will increase a lot. Starting from being beneficial to energy conservation, the new standard requires that the general layout and design of buildings should be beneficial to residential energy conservation.
