The urban population increases continuously since the industrial revolution, and the residential buildings have the primary responsibility for the total energy demand. There is a need for the analysis of the residential building stock for energy efficiency and sustainable planning. However, energy modeling and simulation in urban scale is expensive in computational complexity and time, due to various building geometries and occupancy types. This research proposes a method to increase the efficiency of the simulation process by reorganizing the building geometries with functional clustering and radiation analysis scaling. In order to accelerate the urban building energy modeling (UBEM) process, the building geometries are modified based on energy simulation standards, then, clustering is determined based on radiation analysis and outside boundary conditions. The candidates are selected according to the selection percentage that has been identified before the process to simulate in building energy software. Three different simulation types are compared to validate the performance of the proposed algorithm with complete model simulations in terms of the error rate of the objectives and the simulation runtime

ANALYZING THERMAL COMFORT OF TRANSITIONAL SPACES THROUGH CLIMATE-RESPONSIVE DESIGN SOLUTIONS Ulu, Ümmühan Nur; Gürsel Dino, İpek; Department of Architecture (2023-1-16) Amount of green spaces in the cities has gradually decreased and left its place to rapid construction as a result of the rapid increase in population and urbanization, causing the temperature difference between the city and the rural area to increase, resulting in the formation of Urban Heat Island (UHI) in cities. The necessity to create comfortable areas in dense cities increases the intensity of energy usage, requiring multi-layered studies to mitigate the urban heat island effect by developing climate-r...
A data-driven approach for predicting solar energy potential of buildings in urban fabric Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7) Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
AN INTEGRATED COMPUTATIONAL FRAMEWORK FOR NATURAL VENTILATION AND AIRBORNE CONTAMINANT DISPERSION ANALYSIS IN ARCHITECTURAL DESIGN Abbas, Günsu Merin; Gürsel Dino, İpek; Department of Architecture (2021-10-8) Over the last four decades, the negative impact of the building industry and the growing environmental crisis have led architects to develop sustainable design strategies for a better-performing built environment. Building performance tools, which are commonly used at the end of the design process, are not integrated into the design synthesis. Therefore, there is no integration between the performance parameters. In the literature, there are many studies focusing on the seamless integration of energy and da...
Sustainable impact evaluation of energy retrofits for school buildings in different climate regions Uluçay, Jülide Arzu; Pekeriçli, Mehmet Koray; Department of Building Science in Architecture (2019) Due to increasing importance of the concepts of energy efficiency and sustainability, retrofits for a large portion of existing buildings have become an immediate necessity. In this respect, different retrofit strategies are employed for increasing the efficiency of existing building envelopes, energy sources, electrical and mechanical systems. Among the existing building types for efficiency retrofit are the school buildings, which differ from the rest due to their special function - education. The activit...
ASSESSMENT OF TRANSPARENT LUMINESCENT SOLAR CONCENTRATORS FOR BUILDING INTEGRATED PHOTOVOLTAICS Bunoti, Timothy; Pekeriçli, Mehmet Koray; Department of Building Science in Architecture (2022-2) Despite the recorded increase in the installed capacity of solar energy resources globally, its use in urban areas is still limited and hindered due to the lack of sufficient solar real estate in cities. Irregularity of the city skyline that often results in large shaded areas and the slenderness of high-rise city buildings that limits the available rooftop area for installing conventional solar PV panels have been the main contributors to this phenomenon. Thus, there is a pressing need to devise creative m...
