Urban areas have become the nodal points of the energy problem. Overcoming such points, thus, is essential for responding to the urgent call for the energy transition. This problem manifests itself especially in the buildings, which are a vital element of the energy transition due to their energy-saving and generation potential. As such, the early urban design phase, where energy and environmental quality concerns are typically dealt with, is of utmost importance to reduce the energy use of buildings, increase generating their energy with renewables, and mitigate urban heat island effect. On the other hand, properly integrating energy performance and urban local climate considerations into urban design practices requires a better understanding of the effect of the design decisions. In this regard, this research focuses on the early design phase of future residential areas to better understand how urban design decisions, particularly those that are related to urban form, affect buildings' energy performance and urban heat island intensity. Thus, it aims to be a step toward integrating energy and urban local climate considerations into urban design practices to help energy transition. In this framework, this study uses a bottom-up, physics-based approach for energy modeling; and conducts evaluations through a total of 162 simulations in the Grasshopper environment via Dragonfly, Climate Studio, and Colibri. In simulations, parametrically designed hypothetical models were used. Since there are three main climate types in Turkey according to the Köppen-Geiger climate classification system, this study relies on climate data available in three cities; namely İzmir (C), Konya (B), and Van (D) as the representative of these three climate types. In conclusion, this research states that, considering the energy demands of buildings, more compact forms are advantageous in terms of heating and cooling needs. When the buildings' active solar energy production potential is examined and the balance between the buildings' energy demand and production potential is considered, less compact and less dense urban forms come to the forefront. Furthermore, research findings revealed that urban heat island (UHI) has significant effects on buildings' heating and cooling needs. When UHI was not considered, the annual heating EUI (energy use intensity) increased by 11-18 %; the annual cooling EUI decreased by 19-58 % compared to the situation in which UHI was considered.

Energy benchmarking for residential buildings
Tereci, Aysegul; Elias Özkan, Soofia Tahira; Eicker, Ursula (2013-05-01)
The impact of the urban form on the energy demand of buildings is difficult to quantify as, usually, the mutual shading of buildings in urban settings is not included in dynamic building simulations. As a result, there is not much information available on how the total primary energy demand is affected by the specific urban form.
Hydrogen Economy Model for Nearly Net-Zero Cities with Exergy Rationale and Energy-Water Nexus
Kilkis, Birol; Kılkış, Şiir (2018-05-01)
The energy base of urban settlements requires greater integration of renewable energy sources. This study presents a "hydrogen city" model with two cycles at the district and building levels. The main cycle comprises of hydrogen gas production, hydrogen storage, and a hydrogen distribution network. The electrolysis of water is based on surplus power from wind turbines and third-generation solar photovoltaic thermal panels. Hydrogen is then used in central fuel cells to meet the power demand of urban infrast...
Life Cycle Assessment with BIM Towards Sustainable Energy Policy-Making: The Case of Urban Transformation in Istanbul
Yayla, Alperen; Kayalica, Mehmet Özgür (2021-10-01)
Buildings are responsible for almost forty percent of global energy. Due to their high consumption of energy, buildings are on the front line of sustainability researches. In Turkey, six million out of twenty-two million buildings need to be demolished and rebuilt to meet seismic standards. These buildings are also far below the standards in terms of energy efficiency. Therefore, urban transformation can be thought of as a great opportunity for energy efficiency. This stud...
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...
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 ...
