Study on the effect of radiative sky cooling on energy consumption of light envelope building
With the rapid development of material science,the application of radiative sky cooling technology in daytime has gradually become a reality.In this paper,the appli-cations of radiative sky cooling technology in lightweight prefabricated house are studied using EnergyPlus software.The results show that the critical values for achieving all-day radiative sky cooling for lightweight prefabricated house are:when ε is 0.9 and 0.98,R is not less than 0.949 and 0.944,Respectively.Compared with the air-conditioning energy consumption under the conditions of ε=0.1 and R=0.5,the air-conditioning energy con-sumption under the conditions of ε=0.9 and R=0.9 can be reduced by 18.7％.The re-search results can provide important reference and guidance for the effective applications of radiative sky cooling technology in lightweight prefabricated house.
