Research On Evaluation System Of Office Luminous Environment

Vision is the most important means to obtaining information from outside world. How to create a good and comfortable luminous environment is a crucial factor for occupants to acquire information quickly and accurately. Thanks to the growing concerns paid to luminous environment quality and proportion of labor force cost in production cost, ameliorating the luminous environment quality has become a significant measure to improve the productivity and competence of the enterprise, and yet the energy crisis and deteriorated environment also result in challenges in lighting energy conservation. So how to make tradeoff between luminous environment and energy conservation comes to be a primary issue for members of lighting profession. To make the two parameters comparable, we need to find a proper quantization method for luminous environment subjective evolution. Many research studies, with plentiful and substantial results, have been carried out on this topic at home and abroad, however these studied do not take the system as an organism system, among parameters of which exist interactive effects. The aim of this research is to make a explorative study in this field.Researches on luminous environment quality evaluation, which involves subjective and objective factors, refer to knowledge of organizational behavior, psychology and etc. The evaluated results of luminous environment are lied on subjective factors, besides physics condition. A luminous environment gives different impression to different persons. In this research we measured people's attitude to the luminous environment and environment condition with survey questionnaires and photometric instruments respectively, and concluded results by analyzing them with statistic and regression methods.The analysis results proved the hypothesis that the independent parameters and parameter compounds existed interactive effects among each other and had strong correlation with dependant parameter (luminous environment evaluation results). We also deduced a simple formula of luminous environment evaluation system, which can express the degree of influence to the evaluated result by environment parameters.
