| Large space building is a kind of special building type with obvious difference from general public buildings in energy consumption characteristics,usage pattern and indoor physical environment distribution.In particular,large space public buildings represented by traffic buildings have increased greatly in recent years.The large area of glass curtain wall is the magnificent symbol of this kind of large space public building,and also is one of the main factors leading to its high energy consumption.As an alternative form of ecological energy saving,double glass curtain wall has been widely popular in office buildings and residential buildings in recent years,and has gradually been applied in large space buildings.However,the disconnection between scheme design and energy saving design at the present stage makes this potential technology become a mere form and fails to give full play to its due effect.The lack of detailed design for the characteristics of large space makes this technology more expensive and useless.How to form the applicable use method of double curtain wall in large space building with performance orientation;How to bridge the gap between design and technology and tap the potential of energy saving design in the scheme stage from the designer’s perspective has become a key problem to be answered at the present stage.Based on this background,this paper large space buildings in cold area as the research object,on the double skin facade has a representative form of composite components in large space building integrated design method to study the potential and energy saving design,aimed at this,for example,solution phase and the possibility of energysaving design integration and the integration of technology and the design is from the huge energy saving potential.Specific research contents include the following aspects:1)based on the measured data,analyze the thermal performance of the double-layer curtain wall applied in large space,and form the standard simulation method and simulation model that can reflect the spatial distribution characteristics of physical environment;2)from the perspective of design,use the parameterized platform to study the influence law of the design parameters of double skin curtain wall on energy consumption characteristics in large space buildings;Through sensitivity analysis and performance optimization methods,a passive energy saving strategy utilization method suitable for the program stage and designer characteristics is formed.3)combined with the actual problem,high-speed in cold area waiting areas,for example,to build real air conditioning system,the use of validation of the standard simulation method,the quantitative analysis of the double curtain wall passive use method and active integration strategies in large space building HVAC actively adjust the use effect and energy saving potential,to guide the practical engineering application. |
