绿色办公建筑照明能耗模拟研究OA

Simulated tests were conducted based on the lighting power density(LPD)limits specified in Stan-dard for Lighting Design of Buildings(GB/T 50034-2013),General Code for Energy Efficiency and Renew-able Energy Utilization in Buildings(GB 55015-2021),and Standard for Lighting Design of Buildings(GB/T 50034-2024).The results indicate that the tar-get values stipulated in GB/T 50034-2024 can reduce lighting energy consumption by 29.60％compared to GB/T 50034-2013.The standards effectively reduce lighting energy consumption in office buildings by low-ering the LPD limits.Representative cities were se-lected from the five lighting climate zones in China,in-cluding Lhasa(Zone Ⅰ),Kunming(Zone Ⅱ),Beijing(Zone Ⅲ),Shanghai(Zone Ⅳ),and Chongqing(ZoneⅤ),and simulated tests were conducted using intelli-gent lighting systems.The results show that using intel-ligent lighting systems can reduce lighting energy con-sumption by 77％.Simulated tests were also performed by reducing the hourly occupancy rate of rooms during 9:00-12:00 and 14:00-18:00 by 5％,10％,and 20％compared to Design Standard for Energy Efficiency of Public Buildings(GB 50189-2015).The results show that a 20％reduction in the hourly occupancy rate leads to a 9.95％decrease in lighting energy consump-tion.It is recommended that green office buildings adopt intelligent lighting systems to reduce lighting en-ergy consumption.
