Article Citation - WoS: 3Citation - Scopus: 4The Effect of Structural Retrofitting and Ventilation Scenarios on the Indoor Microclimate of a Historical Library: The Necip Pasa Library, Turkiye(Elsevier Ltd, 2024) Coskun,T.; Arsan,Z.D.; Akkurt,G.G.Structural retrofitting in buildings may result in changes in the indoor microclimate. Chemical, mechanical and biological deterioration can be seen in the cultural properties as a consequence of substrates and inappropriate microclimatic conditions such as high indoor temperature, relative humidity and fluctuations of them. The primary aim of the study is to evaluate the effect of the structural retrofitting, that the building underwent, on the chemical degradation risk of the library collection based on two different ventilation scenarios. One is natural ventilation which is an existing situation since the building is free-floating. The other one implementing a mechanical ventilation system into the building. To be able to compare the microclimate that affects the library collection pre- and post-retrofitting, two models are developed in DesginBuilder and simulated for both scenarios. According to the results of the post-retrofitting model, mechanical ventilation reduced the risk of chemical degradation by 38 %, while natural ventilation did not cause any effect. Natural ventilation gives a similar output in the pre-retrofitting model as in the post-retrofitting model. Mechanical ventilation in the pre-retrofitting model achieves a 33 % reduction in chemical degradation risk. Structural retrofitting only achieves a 1 % reduction in the chemical risk level for both ventilation scenarios. Thus, its effect on the indoor microclimate is insignificant. This study shows that creating simulation models effectively assesses potential risks pre-post-structural retrofitting or any retrofitting in historical buildings. Simulations reveal that mechanical ventilation is a better choice for decreasing chemical degradation risks for the library. © 2024 Elsevier LtdConference Object Citation - Scopus: 2Effect of Building Envelope and Environmental Variables on Building Energy Performance: Case of a Residential Building in Mediterranean Climate(Springer Science and Business Media Deutschland GmbH, 2023) Taşer,A.; Uçaryılmaz,S.; Arsan,Z.D.At least 30% of the World’s energy consumption and greenhouse gas emissions originate from buildings. Thus, design decisions should be well studied during the design phase of buildings following energy efficiency approaches. Environmental variables and properties of the building envelope are significant for energy efficiency. Thus, this study aims to investigate the potential of a residential building in the Mediterranean climate of İzmir, Turkey, regarding decreasing energy use and understanding the significance of architectural decisions during the design stage of buildings. Eight design scenarios were created by defining seven variables affecting energy consumption for room electricity, heating, and cooling. The first three scenarios focused on environmental-related variables, i.e., surrounding buildings, ground surface materials, and building orientation, while the last five scenarios investigated building envelope-related variables, i.e., thermal transmittance of the wall, floor and roof, glass, window frame, and door types, shading elements, and natural ventilation. Then, energy modeling and simulation are applied to test their potential for minimizing energy consumption. Research findings proposed that early architectural design decisions significantly influenced the case building’s energy performance. Thermal transmittance of the building components provided an annual energy saving of 22.4%, thus, was seen as the best-performed variable for the case building. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.
