基于低碳要求的教室照明改造过程中照明功率密度指标初步探讨与分析——以上海市教室改造为例OA

For irregular classrooms in Shanghai,the application of lighting power density evaluation index in classroom lighting retrofit faces challenges.This paper first analyzes the measured data of Shanghai primary and secondary school and kindergarten classrooms in the past three years to explore the application of the lighting power density calculation method to the actual dimensions of different areas and classrooms,and then proposes an improved calculation method by combining the concept of room index in the national standard and verifies it using simulation.The results show that using the room index to correct the lighting power density index can more accurately reflect the actual situation of the classroom light environment for both regular and irregular classrooms.This is of practical significance for the further improvement of the evaluation standard of classroom lighting power density based on low-carbon requirements.
