Master Thesis An Experimental Investigation Into the Effects of High Thermal Mass on Building Performance(Izmir Institute of Technology, 2019) Karataş, Özgür; Başaran, Tahsin; Başaran, Tahsin; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of TechnologyThe focus on energy efficiency in buildings has contributed to the increased interest in vernacular architecture using locally available materials. Monotype architecture has spread across Anatolia during last century despite builders having centuries of knowledge of vernacular dwelling. Climatic conditions are specific to geographical locations, therefore the architectural solutions respecting climatic conditions are also specific. Local construction materials are in harmony with the surroundings because they have previously been part of the current environment. The main aim of this thesis is to investigate and simulate the effects of high thermal mass on the thermal environment of cave dwellings. The case study was undertaken in a cave dwelling carved out of a fairy chimney in Ürgüp, Cappadocia. Data loggers were placed in the dwelling to observe the annual temperature and relative humidity fluctuations. Measurements showed that the interior temperature fluctuated around 18°C in January and 20°C in July, and the relative humidity fluctuated around 70% in January and 65% in July. These measurements showed that the interior conditions were thermally comfortable as a result of the high thermal mass of the cave dwelling. DesignBuilder software was used to simulate the thermal behaviour of the cave dwelling. The thermal conductivity, specific heat and density of the main material, volcanic tuff rock, were measured and defined in DesignBuilder. After defining all the inputs and boundary conditions, the numerical results obtained from the DesignBuilder provided thermal outputs which agreed with the experimental results.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.
