Comprehensive Building Energy Consumption Sensitivity Analysis in Hot Summer and Cold Winter Zones
Using the EnergyPlus software,numerical simulations were carried out for buildings in the hot summer and cold winter regions of Chongqing,Wuhan,Nanjing and Shanghai.The simulations examined the impacts of nine factors on building energy consumption:orientation( BO) ,window thermal conductivity ( WinC ) , window transmittance ( WVT ) , wall thermal conductivity ( WC ) , wall solar absorption rate ( WSA) ,wall specific heat capacity ( WSH ) , roof thermal conductivity ( RC ) , roof solar absorption rate ( RSA) ,and roof specific heat capacity( RSH) .Initially,a global sensitivity analysis was conducted,simu-lating 4000 random combinations within the variable range.Findings indicated a significant influence of wall thermal conductivity,wall solar absorption,roof thermal conductivity and window thermal conductivity on building energy consumption in these cities.Following this,a local sensitivity analysis based on the four primary factors was undertaken.This involved individual optimization of each element,which showed that the energy consumption ratio could potentially be reached to 56.43％,56.83％,56.44％,and 55.47％, respectively.
