    Optimization of Energy Consumption and Thermal Comfort in Historic Buildings: Case Study of İzmir National Library Building, Türkiye
    (01. Izmir Institute of Technology, 2023) Özsavaşcı, Umut; Durmuş Arsan, Zeynep; Gökçen Akkurt, Gülden
    The 'library,' as a building type, is the visiting space of researchers and storage space of wisdom of past and present thinkers. Historic libraries host unique pieces of cultural heritage such as books, manuscripts, documents, maps, artifacts, paintings, sculptures, and frescos from the previous generations. The thesis aims to reduce energy consumption and improve occupants' comfort while paying attention to degradation risks of paper-based collections in the historic İzmir National Library Building, Türkiye. Thus, it examines building retrofit actions with different impact criteria and conducts the optimization tool to define the most optimal ones. First, three degradation risk assessment procedures were determined for the paper-based collections of the İzmir National Library Building. Within the scope of the thesis, the library building was monitored between 01.10.2016 - 01.10.2017. According to the results of the monitoring process, mechanical, chemical and biological degradation risk analyzes were carried out. The digital simulation model of İzmir National Library was prepared in DesignBuilder v. 7.0.0.102 software and calibrated monthly for a year via hourly air temperature data. Three retrofit optimization scenarios, i.e. neutral, low and high risk impact criteria, were defined by grouping different design variables such as glazing type, exterior door material, pitched roof floor construction, exterior wall construction, heating set point and cooling set point of HVAC system. The objective of optimization was reducing energy consumption and discomfort hours at the same time. The simulation results showed that all three retrofit actions reduced energy consumption and discomfort hours. Scenario 3 was the most successful among other scenarios, providing energy savings by 26.6% and reducing discomfort hours by 80.3%, according to the base case. Besides, there was no significant change in the degradation risk analyzes according to the base case.

    Investigation of the Indoor Microclimate of Historic Agios Voukolos (aziz Vukolos) Church in İzmir To Determine and Imporve Thermal Comfort Conditions
    (Izmir Institute of Technology, 2022) Akın Yalçın, Damla; İpekoğlu, Başak
    The conservation of the historical building by improving the thermal comfort conditions contributes to the reuse of the buildings. Besides thermal improvement, the authentic values of the historical building should be taken into consideration. The aim of this thesis is to examine the effects of indoor microclimate characteristics of historic Agios Voukolos Church on the occupants and the wall paintings of the building, and to bring improvement suggestions that consider the values of the historical church by evaluating the thermal comfort conditions. The method of the study consists of on-site examination, on-site measurements of microclimate parameters, calculations and surveys. Air temperature, relative humidity, air velocity and mean radiant temperature measurements were conducted. In order to determine thermal comfort level, Predicted Mean Vote (PMV)–Predicted Percentage Dissatisfied (PPD) method developed by Fanger (1967, 1970) was used and survey studies were carried out during activities in winter. The threshold values specified in the ISO 7730:2005 and EN 16798-1:2019 standards were taken into account. According to the calculations, it was understood that the occupants felt warm in July and August, and cold in November through March. Survey study conducted in winter also confirmed that occupants are not satisfied with thermal comfort conditions. Additionally, respective UNI 10829:1999 standard and the decree published by the Italian Ministry of Culture in 2001 were used to determine the effect of indoor microclimate on wall paintings and ornaments. As a result, secondary glazing system, nighttime ventilation and radiant heaters were suggested for thermal improvement.

    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.

    Restoration and Presentation of Byzantine Defense Structures in Cilicia
    (01. Izmir Institute of Technology, 2021) Kenar, Aylin; Turan, Mine
    The aim of this study is to evaluate current restorations and presentations of Byzantine defense structures in terms of sustaining and enhancement of the cultural heritage values and their success in solving conservation problems. So, better management of future interventions may be possible. Case study approach was undertaken: Three castle ruins in Cilicia, Turkey were focused on: Yılan and Feke castles and Kızkalesi in Korykos. The cases are located in the present-day rural areas. They are restored recently. The study consists of literature review, site survey, documentation and analysis of geographic characteristics, historic background, morphologic characteristics, construction technique and material usage and conservation activities of the case studies, identification of the cultural heritage values and conservation problems before and after interventions at the landscape, site and building scales; and discussion of the effects of the interventions on values and problems in comparison with case studies from abroad. As a result, it was determined that interventions were either unsystematic or implemented more than necessary. There is lack of a holistic approach for interventions. While some portions were intervened, others were left in-situ without any interventions. There is a tendency for reconstruction and reintegration in general. It was seen that current interventions either sustain already accumulated cultural heritage values or they have negative impact on them. Consequently, enhancement of values is not observed. Meanwhile, some of the conservation problems were ignored.

    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.
