Envelope performance

  • 0,20 W.m-2.K-1
  •  Performance-based and refined design of building envelope
    The project is an exhibition building. Compared with common public buildings, the building has high personnel density (0.3p /㎡), large heat dissipation capacity of exhibition equipment (about 60-80W /㎡), and intermittly runs .Due to the high-performance building envelope, the ultra-low energy consumption building can meet the requirements of heating comfort without providing a lot of heat in winter, which leads to the expansion of the influence of indoor heat dissipation equipment and other heat disturbance factors on the cold and hot demand.According to the characteristics of the project, the original extensive architectural design mode is changed, the designers uses the way of performance-based and refined design.
    Through the simulation of the influence of different external insulation thickness on the cooling and heating load and the economic analysis, it is found that there is no need for 250-300mm external insulation as conventional ultra-low energy consumption buildings. When the insulation thickness reaches 150 mm, the increase of the insulation thickness has less influence on reducing the building heat demand. On the contrary, it is not conducive to the building heat dissipation at night in summer and it results in the increase of cooling load in summer.
