Outer shade products for the importance of energy conservation
Release Time | 2017-03-03
Glass curtain wall is a modern high-end buildings more use of the outer envelope, is the building heat exchange, heat conduction the most active and most sensitive parts, with the development of China's glass curtain wall, last year the country has more than 1.5 million square meters, The total area of the glass curtain wall is more than 3 million square meters. Metal glass curtain wall with lightweight, non-flammable, shock, rapid construction, etc., in modern urban high-rise, fire, shock, construction safety requirements under the premise of an irresistible trend, the future will become the mainstream of high-rise building design. But the glass curtain wall is the traditional wall loss of heat loss of 5 to 6 times the curtain wall energy consumption accounts for about 40% of the entire building energy consumption, so the curtain wall of energy conservation has an extremely important position.
2) solar radiation intensity greater than 240 kcal / m;
3) sun exposure indoor depth greater than 0.5 meters;
4) sun exposure indoor time more than one hour;
Therefore, the use of shading measures is not only the glass curtain wall building energy-saving design of the necessary means, but also the standard higher glass curtain wall architectural design of the necessary means. Building shade, is an essential part of the building, in the hot summer, it can prevent the adverse effects of direct sunlight, improve the indoor thermal environment and light environment for human normal learning, work and life to provide protection, which is the most important shade function. In addition, the shade of the building is also closely related to the many aspects of the use of the building function, and the building's thermal environment (insulation, insulation, ventilation), light environment (diffuse reflection), sound environment (sound insulation) and architectural art is closely relationship. The shade of the building, according to its relative position with the building, can be divided into built-in shade and external shade.
Built-in shade, commonly used roller blinds, blinds, Roman curtains, cloth curtains and other forms; external shade, commonly used sun visor, shade louvers and other forms.
"In ensuring good indoor natural light at the same time, external shade can block 100% of the direct solar radiation, the radiation radiation, reflected radiation shielding rate can be greater than 70%, the total solar radiation blocking rate of up to 85% , Which is the effect of inner shade, small blinds that can not be achieved "(quoted from" Ultra Low Energy Building Technology and Application ", p. 111). It can be seen, outdoor shade than indoor shade in the building energy efficiency is more obvious.
"Public building energy efficiency design standards" in the proposed hot summer and warm winter, hot summer and cold winter area of the building and cold areas in the cooling load of large buildings should be set to external shade. External shade can be divided into fixed and electric.
In the architectural design requirements, when the building with the following conditions (higher standards of construction of the room, only 1 to 2 two) will use shade measures:
1) indoor temperature greater than 29 ℃;2) solar radiation intensity greater than 240 kcal / m;
3) sun exposure indoor depth greater than 0.5 meters;
4) sun exposure indoor time more than one hour;
Therefore, the use of shading measures is not only the glass curtain wall building energy-saving design of the necessary means, but also the standard higher glass curtain wall architectural design of the necessary means.
