Research On The Simulation Methods Of The Lighting Energy Consumption For Office Buildings

Based on the requirements and characteristics of the lighting environment in office buildings, considering the factors of natural lighting, lighting design and human behavior, the author systematically proposed a lighting energy simulation approach for office building. The main work of this paper includes the following aspects:1. Based on the observation data of the daylight climate in China, the author proposed a daylight climate model, which is applicable to the climate in China, and also typical climate data as well.2. The dynamic lighting environment and lighting energy simulation methods were carried out, and validated.3. The mathematical model of the lighting system was carried out. And quantitatively analyzed and compared among the various types of lighting control system.4. Study on the human behavior model associated with the light environment, and based on the survey results on site, a simulation approach for open-plan office was proposed.5. Integrated the lighting environment simulation with the thermal environment, a design method based on the overall energy efficiency of buildings is proposed.The daylight climate models and data presented in the paper have been applied to the revised national standard "daylighting design standard for buildings" GB 50033-2013, in order to provide a basis for daylighting design.Finally, several typical engineering applications were discussed in this paper, a quantitative analysis on the influence for lighting energy consumption was carried out, considering daylighting design, lighting design, control and human behavior factors, to clarify and correct some errors exist in the practical application of lighting and architectural studies and design, which provides important reference for optimization design.
