Glass building is a rich, extensive architectural form, which mainly refers to a large area of the use of glass building. As the glass building fashion, light and transparent, since the 20th century, 70 years, the development and application of glass construction has reached an unprecedented height. However, the widespread use of the glass curtain wall also brings many problems, such as: a large number of energy consumption, serious light pollution, a large number of carbon dioxide emissions and line of sight interference. Among these many problems, the large consumption of energy, especially in cold areas, has been a major aspect of the development of glass buildings. If the energy waste problem is not resolved, the cold area of glass building development will be very limited, and even can be said to be stagnant.
(2) summer to minimize solar radiation; (c) summer should take full advantage of natural ventilation, the winter to avoid the direct blow to the cold wind blowing; (2) summer to minimize solar radiation; (c) summer should take full advantage of natural ventilation, Attack.
(2) Plane layout: For glass buildings, from the layout of the layout to be analyzed, should be partitioned, that is, south to the main room and large space, and open a large window or use glass curtain wall, and traffic and auxiliary room arranged in the north or east To open, should open a small window or plug glass curtain wall.
(3) plane shape: for the glass building, we consider the south side is the benefit side, the other three sides as a heat loss surface, by comparing with the square plane, can draw the conclusion: glass building plane should be arranged according to the long axis , Side length to take 1: 1.5 ~ 1: 4 is appropriate
(4) Body shape: body size refers to the building and outdoor air contact with the surface area of the building volume surrounded by the ratio. The larger the coefficient, the greater the area of heat dissipation shared by the unit building space, and the more energy consumption. From an energy-saving point of view, a reasonable design should be based on the principle that the radiant heat absorbed by the south-facing glass surface should be maximized as much as possible by its outward loss of heat.
(5) Surface area coefficient (other surface area of the building and the ratio of the south area): For the glass building from the more sunshine radiation, reduce energy consumption point of view, the smaller the surface area coefficient as possible. Therefore, I from the energy-saving sense, the long axis toward the east and west of the rectangular shape of the best, followed by a square, while the long axis toward the north and south of the rectangular shape of the building energy-saving effect is the worst.
