Research On Ieq General Assessment Model Of Classrooms In Universities

The classroom is an important place where most formal education takes place.A high level of indoor environmental quality(IEQ)is a key factor in achieving a healthy environment in the classroom.Different aspects of environmental quality will affect the quality of teaching,learning efficiency and student test results.In-depth study of its influencing factors and parameter priorities will help.In order to obtain a better balanced solution in environmental assessment and optimization decision-making.This paper is mainly aimed at the teaching space of colleges and universities,aiming to establish the cumulative influence of multiple environmental factors on the quality of indoor environment,establishes the evaluation method of indoor environment quality in classrooms in universities,and further analyzes the influencing factors of environmental quality of sub-categories and the properties of the parameter of classrooms in universities.The requirements for the quality of the indoor environment in classrooms in universities have their particularities.Different aspects of the environmental quality will affect the quality of teaching,learning efficiency and student test results.In-depth study of its influencing factors and parameter priorities will help in environmental evaluation and optimization.A better balanced solution can be obtained in decision-making.According to literature reading and research,it is found that most models in previous studies do not consider spatial type differences,and in objective measurement,there is no unified standard for temporal addition.At the same time,it is found that subjective questionnaires often cannot accurately reflect the indoor environmental quality.At the same time,in recent years,the wide application of intelligent indoor environmental monitoring equipment,and related research on the relationship between objective environmental parameters,environmental quality evaluation,and human comfort have been carried out for many years,and many relevant standards have been introduced.Therefore,this study chooses objective data-standard.The method of delineating the comparison serves as the basis for the evaluation method.This paper proposes an evaluation method for the indoor environment quality of classrooms in universities.This method combines multi-layer Fuzzy Comprehensive Evaluation(FCE)and Analytic Hierarchy Process(AHP)to construct an IEQ evaluation model for classrooms in universities.It is innovatively proposed that for different stages of use of the classroom,different evaluation qualities need to be included in the environmental quality evaluation,and establish a time-weighted method for obtaining specific index values by time-weighting objective measurement data.This method is suitable for indoor measured objective environmental data,and conducts real-time and long-term monitoring of indoor environmental data.The time addition method is used to add the instantaneous quality of the indoor environment in the time dimension,and the sub-comfort index value and the final indoor environment quality evaluation index,namely the general assessment index(GAI)are obtained through the weighted corresponding weights in the IEQ evaluation model.The practical application of the evaluation model was carried out by taking the three classrooms of the Zhongshan Institute of Sipailou Campus of Southeast University as the research object,and two consecutive periods of continuous monitoring in the winter of 2021 and the spring of 2022 were carried out on the research object,and the IEQ evaluation model was used to obtain the weighted vector of the single-day time score,the sub-comfort index value and the general assessment index,the horizontal comparison between classrooms in the same monitoring period and the longitudinal comparison of a single classroom in different monitoring periods were carried out.Further micro-viewing and analysis of the monitored objective environmental parameters are carried out to try to explain the formation law of each index value and obtain the characteristics of the objective environmental parameters of classrooms in universities.
