| The greening of the facade has great potential for building energy-saving and cooling.In this paper,through the research methods of theoretical research+experimental testing+calculation analysis,the heat and mass transfer characteristics of the facade green building under different climatic conditions,the correlation analysis between the parameters of the vegetation layer and the environmental parameters,the changing rules of the relevant parameters of the vegetation layer,and green The research on the content of phytoplasmic wall energy balance reveals the changing characteristics of the thermal process of the facade,and beneficially complements the research on the transfer of the afforestation thermal mass.The results show that there are certain differences in the correlations between vegetation parameters and environmental parameters under different climatic conditions.The attenuation of solar radiation intensity by the vegetation layer is mainly concentrated in the thickness layer of 0-30 cm,and the attenuation rate is as high as 91.8%.The optimal thickness of the vegetation that attenuates the solar radiation is 30cm;the attenuation of the vegetation layer can reach 4℃;the optimum thickness of the vegetation with the temperature attenuation as the goal is 35 cm or more;the thermal comfort of the interior of the facade of the green building The sexual parameters show the characteristics of lower temperature and higher relative humidity.In the energy dissipation process of the vegetation layer,transpiration and heat radiation and net long wave radiation heat dissipation are the main ways of energy dissipation.The sum of the two accounts for more than 80%.The sum of heat dissipation items only accounts for about 10%;the energy imbalance rate shows a trend of increasing with the sunshine intensity and decreasing the unbalance rate,but they are all lower than 15%.The conclusions of this study have improved the content of thermal mass transfer characteristics and energy balance of green building construction,and provided technical reference and data support for thepromotion and engineering application of vegetation construction in the field of ecological energy conservation. |
