Faculty of ArchitectureLibraries are collections of recorded information which can host cultural heritage values that must be protected against mechanical, chemical and biological degradation. To prevent degradations, libraries require stable indoor climates with minimal temperature and relative humidity fluctuations and low concentrations of indoor air pollutants. Aim of the thesis is to investigate if installing a HVAC system is effective in improving the indoor climate of a historic library as a long-term preventive conservation method on the preservation of paper-based collections. Tire Necip Paşa Library in İzmir was selected as the case building which underwent restoration and a HVAC system integration in 2015. Library’s indoor climate was investigated before 2015 which allowed the comparison of pre- and post-restoration periods. Within the scope of this thesis, library was monitored at five locations between 2019-2021. 2019-2020 monitoring results were compared to pre-restoration monitoring results in terms of degradation risks and ASHRAE Chapter 23 control classes. Pre- and post-restoration indoor climates satisfied A1 and AA control classes, respectively. While there were mechanical and chemical degradation risks before restoration, no risk was observed post-restoration. There was no biological degradation risk during either periods. Additionally air pollutants were sampled during summer and winter of 2020-2021 which showed high SO2 and NO2 concentrations. Lastly the BES model of library was prepared and calibrated to investigate if existing HVAC system will continue to provide a stable indoor climate on future. The results of 2050 and 2080 simulations showed that HVAC system will struggle to provide a stable indoor climate.Master Thesis Modelling of Indoor Climate of Historic Libraries for Preventive Conservation of Papper Based Collections(Izmir Institute of Technology, 2016) Coşkun, Turgay; Gökçen Akkurt, Gülden; Durmuş Arsan, Zeynep; Coşkun, Turgay; Gökçen Akkurt, Gülden; Durmuş Arsan, Zeynep; 02.02.

Faculty of ArchitectureLibraries were seen as an education and cultural center. Cultural properties in libraries can deteriorate chemically, mechanically and biologically because of inadequate indoor climate (temperature, relative humidity and whose fluctuations) and substrates. The aim of the thesis is to improve indoor climate of the historic libraries to preserve paper based collections by preventive conservation approach. As a case study, Necip Paşa Library was selected. The Library, which houses 1147 valuable manuscripts, was built in 1827 in Tire-İzmir-Turkey and has no heating-cooling system except entrance zone. Preventive conservation approach was performed in three phases. As the first phase, the indoor microclimate of the Library was monitored for one year. Secondly, the chemical, mechanical and biological degradation risk analyses are carried out on the manuscripts based on the measurements. According to the measurements, only the chemical degradation is observed. Lastly, the library was modelled via DesignBuilder v4.2.054, and calibrated with respect to ASHRAE Guideline 14. To minimize chemical degradation risk, natural and mechanical ventilation strategies are integrated into DesignBuilder. The natural ventilation scenario did not influence on chemical degradation risk, while the latter diminishes the chemical degradation risks for some extent. The building had two main interventions: the addition of a semi-open entrance space and the closure of this space by wooden-framed windows. To evaluate the effect of these interventions, two different models are developed via DesignBuilder. The simulations of the models did not exhibit any difference on the indoor climate comparing with the existing construction. Evaluation of the scenarios and interventions result with that the mechanical ventilation system is the most effective solution for the Library.
