Evaluation of suitability of university ladder classroom environment on humans
Abstract
Evaluation of the suitability of university ladder classroom environment on humans is an effective approach to improve the quality of the indoor environment and protect human health. However, there are unresolved issues regarding the suitability of university ladder classroom environment for humans. For example, the design of enclosure structure and heating ventilation and air conditioning (HVAC) system is unreasonable, and the indoor air quality does not meet the required standard. In this study, the suitability of university ladder classroom environment on humans was considered the research object. The evaluation indices of indoor environment were selected from indoor air quality, indoor thermal and humid environments, light environment, and sound environment. And the health and comfort of users were taken as the evaluation indices of users. According to the results of expert investigations and case measurements, the index weight was determined by the expert-entropy weight method, and a complete evaluation system of indices was built. There were two first-level, six second-level, and fourteen third-level indices in the evaluation system. The evaluation indices of each level with the largest weight were indoor environment (0.5940), user health (0.2530), and indoor temperature (0.1175) respectively. By comparing the actual learning effect to the evaluation results, the applicability of the evaluation system was determined. The evaluation system of the suitability of university ladder classroom environment on humans is convenient for operators to identify the weak points between humans and the environment. The evaluation system is endowed with important theoretical and practical significance to realize the green development of colleges and universities and build an environment-friendly campus.
