The Analysis And Evaluation Of Indoor Air Quality Of Civil Building

In recent years, indoor air quality serious declined because the organism synthesis material was extensively applied equipment and instrument in the room,which rendered a lot of vapor organism compound gases sprayed,so indoor air quality has become a public focus. Indeterminacy exists in the influencing factors and indoor air quality of civil building engineering itself.According to the code for indoor environmental pollution control of civil building engineering,we made a systematic study on many influence of indoor air quality and evaluation method of indoor air quality,using grey system theory,in this paper,which provide scientific warranty in order to improve indoor environment quality and establish standard of indoor environment quality.Firstly,a systematic analysis on main pollution material and pollution source of building indoor is made in this paper,we had made a test of indoor air quality of four office blocks.We analyze the influence of indoor air contaminations on inhabitants' subject evaluation to indoor air,and calculate the degree of grey incidence between indoor contamination level and dissatisfaction rate at indoor air or in symptom rate.This study reveals the relationship between this factors,and shows which we should pay more attention to in design and maintenance of indoor environment.Because of the indeterminacy,we made the determinate indoor air quality models into grey models,which areimportant tools to forecast evaluate and control indoor contamination level .At analysis establishes a grey method of assessing indoor air quality and illuminates the application of grey cluster in predigesting the evaluation parameters.In order to guarantee the indoor air quality after the civil building engineering being finished,it is necessary to made evaluate of the indoor air quality advance.Finally,this paper puts forward some concretely measures for some main contaminations.
