In this paper

a new envelope of buildings

the breathing-type glazing curtain wall with energy storage function

is put forward based on the concept of low-energy consumption buildings

and the analysis on the bottleneck related to prevent heat loss in enclosed structures of building and the weakness concerned with thermal performance of building envelopes.The structure is studied and designed. Considering the energy conservation of traditional glazing curtain wall with thermal channel

a new thermal calculation model for breathing-type glazing curtain with energy storage function is established.Combined with the calculation results of engineering examples

the characteristic parameters of the new envelop is analyzed in detail.The results show that heat transfer coefficients of the new envelop in winter and summer are within 1 W·m-2·K-1 and superior to those of traditional glazing curtain wall with thermal channel.The time of heat lag in summer and winter is triple and twice that of traditional curtain wall.In the region with heavy solar radiation intensity and small wind speed

the heat insulation and time of heat lag in summer are worse

but it is helpful to heat preservation and time of heat lag in winter.The new envelop has the characteristics of simple structure and easy operation

which may be helpful to the development of glazing curtain wall in the future.
