摘      要：The energy consumption of office buildings has increased sharply since the 21st century with the increasing ur-banization *** this stage,the energy consumption of office buildings in China mainly comes from air conditioning and *** paper obtains the regression equation of natural lighting illumination and radi-ant heat gain under different curtain conditions through experiments and simulations,and gives the theoretical calculation process of curtain regulation of office thermal and light environment and energy *** and Ecotect software were used to analyze the thermal and light environment and energy consumption of the *** results show that setting curtains in the room can effectively improve the indoor thermal light en-vironment,the higher the transmittance of curtains the lower the lighting energy consumption,the higher the number of high temperature hours of natural room temperature and the greater the radiant heat *** room with thick curtains has the lowest energy consumption for air conditioning in summer,followed by the room with thin curtains,and the room without curtains has the highest energy consumption for air *** room without curtains has the lowest energy consumption for artificial lighting,the room with thin curtains has the second lowest,and the room with thick curtains has the highest electricity consumption for artificial *** air conditioning energy consumption accounts for the main building energy consumption,followed by the lighting energy *** setting curtains in the office,the air conditioning energy consumption caused by the solar radiation heat entering the room through the exterior windows is smaller than the lighting energy consumption caused by artificial ***,the installation of internal shading with moderate trans-mittance and good thermal insulation performance can make the energy saving of lighting and air conditioning energy consumption reach the
