The problem of depletion and rapid consumption of natural resources has forced engineers to design houses that consume less energy with more sustainable materials. However, simply minimizing energy consumption is not enough; at the same time, it is necessary to keep the indoor quality at the maximum level for a healthier environment and higher level of production. BIM based design and analysis has the potential to help achieve both targeted energy needs and visual & thermal comfort levels. Previous studies looked into increasing visual comfort while considering the energy performance of the buildings or performed simulations to keep daylight performance and energy efficiency at an optimum level. Moreover, there was also some research on optimization in the field of costs, such as life cycle cost and life cycle energy relationship or the monetary analysis of visual and thermal comfort. However, an optimization study aiming to keep the energy need low while increasing the thermal comfort and visual comfort, in other words, a study that evaluates all three criteria at the same time, has not been encountered. In this study, an analysis to support a greener and more environmentally friendly design, which reduces the building energy consumption while increasing thermal and visual comfort at the same time, has been performed by using BIM technology together with a multi-objective function to assess tradeoff between these criteria. The results of the analysis show how certain design parameters effect energy efficiency and thermal and visual comfort levels and provides a potential to support design decisions not only considering energy efficiency but also the comfort of the occupants.

A multiobjective approach to energy environment planning problem Arikan, Y; Kilic, C (1996-05-16) The energy planning problem has gained a new dimension in view of the effects of energy production and consumption on environmental decline and ecological damage. The problem was usually formulated in total cost minimization form and the environmental effects of energy activities were not taken into account. It has been well understood now that decisions concerning energy supply cannot be based on a single objective, since energy policies have multiple consequences which cannot and should not be ignored. Th...
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 Energy and Economic Comparison of Building Envelope Types in Ankara Shorbagı, Mustafa Ibrahım; Çakmaklı, Ayşem Berrin (null; 2015-05-30) One aim of sustainable design may be, “to protect important resources such as energy from depletion and the reduction of the release of poisonous gasses, such as CO2 , to the atmosphere”. For this purpose, buildings which are a major cause of energy resource wastage must be designed in such a way to avoid such energy losses. In developing countries like Turkey, where much energy is exported to satisfy her needs, necessary methods of energy reduction were required. Thus regulations such as the TS 825 (Turkis...
A Facade mapping method to understand human comfort in buildings with highly glazed facades Tüzer, Ceren.; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2019) The energy demand of societies increases continuously with related to technological improvements, population increases and daily needs. Building sector is one of the highest energy consumer sector. Office buildings are also critical type of buildings, because these types of buildings generally accommodate lots of occupant and there is high demand of energy for lighting, heating, ventilation, and air conditioning to provide indoor air quality, thermal and visual comfort. The buildings with glass curtain wall...
Parametric analysis of BIM-based building energy performance for supporting multi-objective optimization Can, Esra; Akçamete Güngör, Aslı; Department of Civil Engineering (2022-5-11) Building energy efficiency comes into prominence as buildings constitute a significant portion of world energy consumption and CO2 emissions. To achieve energy-efficient buildings, energy performance assessments should be conducted meticulously, yet it is difficult to comprehensively estimate the buildings’ energy consumption since energy performance assessments are complex multi-criteria problems that are affected by many factors such as building orientation, envelope design, climatic conditions, daylight ...
