Master Thesis Comparatic-Ve Energy Performance Assesment of Hemp-Clay as Building Block Material(01. Izmir Institute of Technology, 2022) Ergün, Betül; Durmuş Arsan, Zeynep; Akkurt, SedatBio-based and earthen building materials have recently started to be used again in seeking sustainable materials to combat climate change. Hemp-based building materials stand out as energy-efficient materials due to their favorable thermal properties, although they still have unstandardized features that vary by location. This study aims to investigate the thermal properties and energy performance of hemp-clay building blocks which are produced with local hemp and clay in the western Aegean region of Turkey for today and the future, leading up the research on hemp-based building materials in the Mediterranean region. The methodology of the research consists of laboratory experiments on material and building energy simulations via DesignBuilder software. Building block samples were produced with 27 different hemp-clay mixtures and tested using a quick thermal conductivity meter. Subsequently, the thermal performance of selected hemp-clay block was compared with conventional wall infill materials such as hollow clay brick, autoclaved aerated concrete, and lightweight pumice block via simulations of the annual energy consumption of an existing residential building in Izmir. Simulation scenarios were generated keeping wall thickness and U-value as constant for the climate of 2020, 2050, and 2080. Hemp-clay building blocks reduced the heating and cooling demands of the case building by 21% and 14%, respectively in 2020. Their energy performance outperformed the other materials' performances even if the scenario walls have the same U-value as hemp-clay walls in today's and the future's climate conditions. Consequently, the hemp-clay building blocks are apparent as a promising material to be improved in Turkey.Master Thesis 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, GüldenLibraries 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 Process-Centered Modeling Experience From Architect's Perspective: a Case Study in a Residential Building in Izmir(Izmir Institute of Technology, 2019) Gülmez Raafat, Rahşan Aytül; Durmuş Arsan, ZeynepPredicting current energy demand and future energy consumption of buildings is the challenging experience for architects. Although there are various dynamic simulation tools that enable them to calculate building energy performance, the complexity of tools poses problems to model, understand process-centered simulation studies and interpret the results. This thesis aims to present, test, verify and criticize the modeling, simulation and calibration processes of residential building from architect's perspective. One of the effective ways to overcome global warming problem is by immediate involvement of architects into energy modeling process. Therefore, the study criticizes the role of architect in process-centered modeling. Process-centered modeling is tested with existing residential building conditioned with air-source heat pump in İzmir-Turkey. Indoor and outdoor environment were monitored from July 2009 to June 2010. Digital model of the building was created by using DesignBuilder dynamic modelling tool, and calibrated for three different periods of heating, cooling and transition. The problems faced during modeling and simulation based on professional knowledge of the architect and simulation tool was exemplified. Finally, the survey was conducted to verify the role of architect tool users in modeling process. Consequently, case study exemplified how the architect conducts a processcentered modeling, and survey showed how his/her modelling experience and knowledge is essential for right management of design process. Mechanical systems modeling is still challenging issue requiring knowledge and experience for architect users..Master Thesis Retrofit Strategies for Energy Efficiency in Historic Urban Fabric: a Case Study in Basmane District, Izmir(Izmir Institute of Technology, 2018) Ulu, Meltem; Durmuş Arsan, ZeynepEnergy efficient retrofit of historic urban stock requires a methodical approach, comprehensive analysis and case-specific solutions. In large scale rehabilitation projects, the retrofit strategy should be developed on how to decide solutions for buildings providing the most energy saving in a short time. This paper presents a pilot study conducted at the neighborhood scale, consisting of 22 pre- and early-republican residential and contemporary buildings in a historic urban fabric of İzmir, Turkey. It aims to develop an integrated approach to identify case-specific energy efficient solutions for retrofit strategy of larger scale historic district. It utilizes building performance simulation (BPS) model, created through the documentation and quick field survey. All case buildings are grouped under three main categories considering their heritage value and building characteristics. Two retrofit packages and three individual operational solutions are constituted by considering five-leveled retrofit impact assessment of the CEN EN 16883:2017 Standard. Within the integrated approach, energy classes of the buildings are calculated regarding Building Energy Regulation of Turkey. Most-related two design parameters, S/V and ground floor area to conditioned volume ratio, on annual energy consumption of the buildings in current cases are identified by Pearson correlation analysis. The simulation results indicated that, three buildings including Building 8, 11 and 21 representing each group can initially be retrofitted. Building 11 has the most energy saving potential through Package 2 in its own group. For all buildings, while maximum energy saving was provided by Package 2 with 48,57%, minimum energy saving obtained from Package 1 with 19,8%.Master Thesis Adaptive Thermal Comfort Analysis of Historic Mosque: the Case Study of Salepçioğlu Mosque, Izmir, Turkey(Izmir Institute of Technology, 2016) Bughrara, Khaled S. M.; Durmuş Arsan, Zeynep; Gökçen Akkurt, GüldenMosques differ from other types of buildings by having intermittent operation schedule. Due to five prayer times per day throughout the year, mosques are fully or partially, yet periodically, occupied. Historic mosques, possessing cultural heritage value, need to be evaluated in terms of thermal comfort. The adaptive thermal comfort method presented by ASHRAE 55 is recommended to be used to analyze thermal comfort conditions of unconditioned buildings. The aim of research is to analyze thermal comfort conditions of historic mosques throughout the year, and to conduct an adaptive comfort analysis. The selected Salepçioğlu Mosque was built in 1905 in Kemeraltı, İzmir, Turkey. The objective is to improve indoor thermal comfort levels by applicable interventions with specific attention to its heritage value. First, indoor and outdoor microclimate of Salepçioğlu Mosque was monitored from October 2014 to September 2015. The physical model of mosque was created via dynamic simulation modelling tool, DesignBuilder v4.2. The model was calibrated by comparing simulated and measured indoor air temperature within hourly error ranges defined by ASHRAE Guideline 14. Whole-year thermal comfort analysis was conducted on monthly basis by using adaptive thermal comfort model. The adaptive comfort analysis of monitoring campaign shows that the Mosque does not satisfy acceptable comfort levels. Different scenarios were applied to better comfort levels. The best improvement is obtained with underfloor heating by which discomfort hours drop into 1369 hours by 31.34%, while it was 3760 hours by 86.08% in the baseline model.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, ZeynepLibraries 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.Master Thesis Rebuilding the Relationship Ignored Between Children and Natural-Built Environment Through Scool Garden Designed by Permaculture Method(Izmir Institute of Technology, 2014) Kılıç, Merve Ayten; Durmuş Arsan, ZeynepChild’s perspective is ignored when designing built environment. Areas where child can contact with nature in built environment have decreased. Natural areas in the city are necessary for child’s development. This study searches for one of the ways of rebuilding relationship between children and natural-built environment via permaculture design system, which took a major role here as a tool used for strengthening tie between nature and children. The basic objective of this thesis is to improve the relationship between children and natural-built environment through design of school garden-playground area. To introduce permaculture method into child education and to equip the child with skills for both self-production of own food and maintain lifecycle without harmful to nature are the secondary aims of thesis. A design proposal on permaculture learning-playing garden is developed and implemented in the Secondary School of Karacaoğlan District in Bornova, Izmir. The questionnaires, seminars, workshops and discussions are performed in both design and implementation phases of this garden, which can be ascribed as a new natural environment in the built one for children. The case study shows that the collaborative platform revealed between child and designer is the essential strategy to rebuild the relationship of children with built environment. Furthermore, it is observed that it is possible to rebuild the relationship between child and natural environment via the education of permaculture design system, when it is provided in appropriate time period of childhood without relying on his/her socio-cultural background, family factor, and natural-built environment that he/she has grown.Master Thesis Retrofitting Existing Mass Housing for Energy Efficincy: a Case Study in Gaziemir Emlank Bank Housing Area, Izmir, Turkey(Izmir Institute of Technology, 2008) Yıldız, Yusuf; Durmuş Arsan, ZeynepEnergy consumption in the extant residential building stock of Turkey is excessive owing to an inadequate regulative framework regarding energy-efficient retrofitting, application deficiency and failures in heating insulation detailing regulated by TS 825 Thermal Insulation in Buildings. Mechanical systems through the operation period of buildings are out of inspection and occupant profile pays attention to size rather than the quality of construction. In the framework of research concerning harmonization with the EU, the building regulations of Turkey have been adapted to the EU Directives promoting energy efficiency and reduction of energy demand in existing buildings. The Turkish Energy Efficiency Law, launched in 2007 in this framework, is the most noteworthy step. In the light of retrofitted housing examples from 11 EU countries, the thesis presents effective and case-specific retrofitting scenarios for a selected residential block in Gaziemir Emlak Bank Mass Housing Area in Izmir, Turkey. The objective is to draw attention to the enormous potential for reducing energy consumption in existing mass housing areas through implementation of energy-efficient retrofitting applications. The thesis discusses scenarios to decrease the energy demand for heating and evaluates the effects of predefined scenarios on cooling loads of selected apartment block. The building energy analysis software, Ecotect v5.50, has been used for the assessment of heating and cooling energy loads based on the current and improved conditions of the building. The thesis demonstrates that it is possible to save almost half of the annual energy consumption of the residential block in Gaziemir Emlak Bank Mass Housing Area by applying appropriate retrofitting scenarios.Master Thesis Life Cycle Environmetal Impact Assessment of a Multi-Storey Residential Building in Izmir(Izmir Institute of Technology, 2012) Aral, Duygu; Durmuş Arsan, ZeynepFor a sustainable development, it is essential to improve the building stock and sector which are majorly affiliated with the negative impacts on environment. The analysis of current situation and establish the basic problems in order to decrease the environmental impacts of buildings. Life Cycle Assessment (LCA) is a holistic and scientific method in the area of environmental impact assessment. While the LCA may be applied to individual building components or specified life cycle phases, it is also possible to assess the environmental impacts of a building from cradle to grave with an integrated approach toward whole life cycle. The purposes of this study are to evaluate the current position of the LCA method, which is a vital component of the sustainability assessment in building sector, and to make a quantitative assessment on the environmental impacts of multi-storey-mass housing which has the primary share of recent residential building stock in Turkey. One residential unit of a mass housing development in Izmir constructed at the last decade, at the edge of the expanding city boundary, was selected as the case object of this study. The life cycle of building is fundamentally examined in three phases, which are: pre-use phase, use phase and end-of-life phase. The Simapro software 7.3.3 and Ecoinvent 2.2, up-to-date database, were selected for the LCA simulation. In addition, as a local input to database, energy data for Turkey was created. As a result of this study, the environmental impacts during the life cycle of a multi-storey building residential unit have been ascertained and the life phases, building components and operational processes which have the heaviest impact on the environment have been determined.
