Energy Efficiency Design Research Of Glass Curtain Wall In Building

The building energy efficiency into the world architecture zone together matter of concern. Outside surrounding protection structure hot working reformance of the architecture direct influence the building energy consumption, the glass curtain wall is one of outside surrounding protection structures which the modern architecture comparatively uses, it not only has realized outside the architecture in the surrounding protection structure the wall and windows and doors together, moreover ingeniously merges into one organic whole the architecture surrounding protection structure use function and the decoration function, causes the building to have the modern feeling and the decoration artistry. But the big area glass curtain wall while provided the good natural lighting actually to bring the heating and the refrigeration energy consumption high hidden danger, it was constructs the energy consumption a weak link. "Public building Energy efficiency on Design Standard" the issue says to the architecture zone and the building curtain wall profession, not only is the opportunity, also is challenges, "Standard" promotes the improvement existing glass curtain wall;"Standard" requests the health development energy conservation glass curtain wall;"Standard" summons the development new energy efficiency glass curtain wall. Therefore, the research glass curtain wall energy efficiency design has the vital significance to the architecture energy efficiency work development.This article introduced outside the glass curtain wall consumed energy and its energy efficiency measure, the parallel connection gathers the investigation and study the Xi'an area 28 buildings glass curtain wall design present situation material to occupy to the glass curtain wall area sets up the glass material, the glass curtain wall supporting way, in the glass curtain wall which the surface area the proportion, the glass curtain wall used uses the visor facility the situation to carry on the thorough analysis, obtainedhas carried on the glass curtain wall energy efficiency design in the Xi'an area some conclusions. In addition, the author also rested on "Civil architecture Hot working Design Standard" to the Xi'an area commonly used 6mm thick ordinary monolithic glass, the 8mm thick ordinary monolithic glass and the 6mm+9A+6mm center spatial glass, the 10mm+9A+10mm center spatial glass heat transfer coefficient has carried on the computation and the comparison. Knew the near for 10 year Xi'an area architecture glass curtain wall the whole energy efficiency level obtained has compared the earth to enhance. But must completely satisfy "Public building Energy efficiency Design Standard" and so on the cold area solely to face the limiting value request to Xi'an which the transparent curtain wall the heat transfer coefficient proposed, needs to use one kind of new energy efficiency curtain wall hot channel type glass curtain wall. And emphatically has carried on the elaboration to the hot channel type glass curtain wall, analyzed the hot channel type glass curtain wall energy efficiency design proposal, has calculated the hot channel type glass curtain wall compared to the center to be spatial glass curtain wall energy efficiency rate, let the people direct-viewing understand the glass curtain wall the energy efficiency design method and the hot channel type glass curtain wall energy efficiency superiority, for the architect, the developer when the design, selected the glass curtain wall provides the reference.
