Indoor air quality assessment in the university library during the Covid-19 pandemic

Abstract

During the COVID-19 pandemic, it has been determined by studies that viruses suspend more in closed and unventilated areas, so the possibility of transmission increases. It has also known that insufficient and poor quality of indoor air causes health problems and their symptoms. Particularly, indoor air quality is a significant problem in libraries where students spend most of their time. Besides, Inadequate indoor air quality in libraries has known to cause learning difficulties, decrease in working efficiency and concentration disorder, as well as negative effects on library materials. In this study, the university library was evaluated in terms of indoor air quality. The measurements of temperature, relative humidity, CO₂, PM₂.₅ values, which are parameters of indoor air quality, were carried out experimentally during the midterm weeks. The measurement results were analyzed and compared with the determined indoor air quality standard values. In addition, indoor air quality was assessed with the satisfaction survey. As a result of the measured parameters and survey data, it has been determined that the CO₂ and PM₂.₅ values may cause problems for the users and the ventilation scheme should be rearranged for this.

Covid-19 pandemi sürecinde üniversite kütüphanesinde iç hava kalitesi değerlendirmesi

Öz

COVID-19 pandemi süresince virüslerin kapalı ve havalandırılmayan alanlarda havada daha fazla asılı kaldığı, dolayısıyla bulaşma olasılığının arttığı yapılan sağlık sorunlarına ve semptomlarına neden olduğu bilinmektedir. Özellikle öğrencilerin zamanlarının çoğunu geçirdikleri kütüphanelerde iç hava kalitesi önemli bir sorun teşkil etmektedir. Kütüphanelerde yetersiz iç hava kalitesinin kütüphane materyalleri üzerinde olumsuz etkilerinin yanı sıra öğrenme güçlüklerine, çalışma veriminin düşmesine ve konsantrasyon bozukluğuna neden olduğu bilinmektedir. Bu çalışmada üniversite kütüphanesi, iç hava kalitesi açısından incelenmiştir. İç hava kalitesi parametreleri olan sıcaklık, bağıl nem, CO₂, PM₂.₅ değerlerinin ölçümleri ara sınav haftalarında yapılmıştır. Ölçüm sonuçları analiz edilerek iç hava kalitesi standart değerleri ile karşılaştırılmıştır. Ayrıca iç hava kalitesi, memnuniyet anketi ile de değerlendirilmiştir. Ölçülen parametreler ve anket verileri sonucunda CO₂ ve PM₂.₅ değerlerinin kullanıcılar için sorun yaratabileceği ve bunun için havalandırma şemasının yeniden düzenlenmesi gerektiği tespit edilmiştir.
