    The Effect of Restoration Interventions on the Indoor Climate of Historic Buildings: Case Study of Tire Necip Paşa Library, İzmir, Turkey
    (Izmir Institute of Technology, 2022) Çağırgan, Umut; Durmuş Arsan, Zeynep; Gökçen Akkurt, Gülden
    Libraries 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.

    Conservation Aimed Evaluation of the Bath Ruin in Gülbahçe, Urla, İzmir
    (01. Izmir Institute of Technology, 2021) Çağlıyurt, Aslı; Turan, Mine
    This study takes into consideration a historic geothermal spring bath house on the coast of Gülbahçe bay in Urla, İzmir. The aim is to identify its cultural asset values and architectural conservation problems. Gülbahçe thermal spring bath house is a historic monument that has preserved its bathing function for health purpose. It is part of the geothermal spring bath group in Urla-Seferihisar region, which is famous with its geothermal sources. The modest structure has preserved its authentic characteristics such as rubbles tone masonry walls exposed without plastering and dimly lighted bathing space circumscribing a pool. Its rubble stone and cement mortar vault reflect the repair attitude of the early Republican era. The monument integrates with its natural setting in between a Mediterranean coated mount and the coast. So, the methodology includes tachometric documentation of the bath house, its visual analysis, historical research and archive research, identification of similar bath houses in Urla-Seferihisar region, comparative study with these similar bath houses, evaluation of the cultural asset values and conservation problems, and proposal for restoration of the bath house.it represents the thermal bathing tradition in the geothermal region of Urla-Seferihisar together with the other baths in Cumalı, Karakoç, Kelalan and Ilıksu. Being positioned within the campus area of İzmir Institute of Technology gives privilege to the monument in terms of its restoration possibility. It will be first scientifically restored thermal spring bath house in its region. As a result, this study carries importance in terms of understanding of the Gülbahçe geothermal spring bath house, and illuminate the way for future studies on vernacular Anatolian bath houses.

    Seismic Analysis of an Ancient Lighthouse by Meso-Scale Modeling Technique
    (01. Izmir Institute of Technology, 2020) Gözün, Safiyullah Üveys; Özdemir, İzzet; Dönmez, Cemalettin
    Modeling masonry structures has always been a difficult subject due to the lack of information about the behavior, the heterogeneity of the masonry materials and complex geometries of masonry structures. In terms of the computational costs and complexity, several methods are proposed in the literature. In this thesis, the capabilities of the meso-scale modeling technique are investigated by means of two experiments selected from the literature and the seismic response of an ancient lighthouse. Brick and mortar type structure is idealized as expanded units surrounded by zero thickness cohesive interfaces representing the mortar behavior. This means that the failure of mortar layers is considered explicitly by means of cohesive surfaces whereas the mechanical response of expanded units is described by Drucker-Prager/Cap model. This approach is used to simulate the in-plane and the outof-plane behavior of masonry walls reported in the literature. After validating the models with the experimental results, implicit-dynamic time history analyses of an ancient lighthouse are conducted by using 2 different earthquake records. The influence of mortar properties on the energy dissipation mechanisms and collapse pattern of the structure are investigated by means of a parametric study. As an attempt to identify the critical earthquake level corresponding to the initiation of sliding within the lighthouse, a set of additional analyses are conducted with scaled earthquake records.

    Image-Based Three-Dimensional Modeling of Izmir Çakaloğlu Khan
    (Izmir Institute of Technology, 2012) Palaoğlu, Ümmühan; İpekoğlu, Başak; İpekoğlu, Başak
    Three-dimensional (3-D) documentation in historic building conservation is important in terms of demonstrating the size, shape, location within the settlement, architectural elements, spatial and volumetric features of the building. Alterations, decay in materials, structural problems and damages can be monitored and updated in image-based three-dimensional models of historic buildings. The focus of this thesis is on the image-based three-dimensional modeling of Çakaloğlu Khan, one of the urban Ottoman Khans in İzmir dating from the 19th century. Çakaloğlu Khan is located in the historic Kemeraltı commercial district, to the southwest of Kızlarağası Khan close to İzmir harbor. The building distinguishes itself from other urban Ottoman Khans by its location, its middle passage plan type, its mass made up of spaces of various heights and original architectural elements. The model utilized two-dimensional documentation drawings of the building consisting of plan, elevation, sections and digital photos. Primarily, the photos were edited using the softwares Zoner Photo Studio 10, Adobe Photoshop Elements 7.0 and Inkscape, following which a solid model of the Khan was built and the photos were attached to the model surface. This model was then transferred to Google Earth, and its location on the earth was determined by entering its x, y and z coordinates. This study enabled access and sharing of the three-dimensional image of the building through satellite. The exterior mass and original architectural elements of the building were documented by using low cost digital technology in threedimensions based on images. The prepared model not only enabled to holistically perceive a building hitherto hidden among densly located buildings, but also created data to discuss numerous alternatives for its conservation decisions.

    Investigating the Efects of Nodes and Landmarks in City Plannig Practice
    (Izmir Institute of Technology, 2003) Böcekli, Burcu; Süel, Akın
    This thesis deals with the analysis of landmarks that are active elements in the formation of ordered urban spaces, in helping the creation of more qualified and identified cities and in increasing the quality of the living environment. It stresses why the landmarks are important for a city.s inhabitants and its visitors and aims to identify certain physical and social elements, which play role on the constitution of landmarks.Human beings and cities have strong interactions, relations and connections with each other. Man has some impressions and impacts from the city that he lives in or that he visited. These impressions are images that are collected from parts of cities. Visual urban elements play an important role on the formation of the impressions that he has. Social, economical and cultural facts are other active elements that effect human beings just like visual urban elements. The most important thing here is, all these experiments and impressions he has, are influenced from the urban environment and its visual elements.This study sees one of the functions of the planner as; lessening the effects of the unpleasant cities that we live in, with the positive effects of some urban elements like landmarks. Looking from this point of view, the first aim of this study is to examine the development and the usage of landmarks throughout history, the second is to define and classify landmarks and the third is to examine and discuss their use in the cities for the betterment of cities throughout history considering the planning principles.
