Computational Investigation of Urban Heat Island Mitigation Scenarios in Educational Buildings

Yazıcıoğlu, Gülin
Recent years have witnessed rapid urbanization due to an increase in population in cities. This will lead to the replacement of natural landscapes with impervious surfaces, and the acceleration of anthropogenic activities, which will increase waste heat. As a result of this, there is a temperature difference between the city centers and their suburbs, which is commonly referred to as an Urban Heat Island (UHI). As a result of the UHI phenomenon, many negative effects are associated with it, such as increased energy consumption, discomfort both indoors and outside, as well as health problems related to it. Compared to other types of buildings, educational buildings are distinguished by their large size, high density of people, and number of unique challenges. Although several studies have been conducted on UHI effects, there has not yet been a comprehensive analysis of UHI effects on educational buildings. This thesis describes a method for generating modified weather files based on UHI for various mitigation scenarios. The six scenarios developed include Cool Pavement (CP), Cool Facade (CF), Green (GR), Cool Pavement-Green (CPGR), and Cool Facade-Green (CFGR), as well as a combination of all these scenarios using ENVI-Met. In this manner, it is possible to examine the impact of each mitigation scenario on outdoor thermal comfort, indoor overheating degrees (IOD), and heating loads. As a result, CP is the most reasonable scenario for mitigating UHI effect as well as decreasing heating loads whereas CFGR is better for decreasing indoor overheated air temperature. In addition, GR scenario performs better for achieving reduced perceived temperature in summer.


Integrated evaluation of urban regeneration projects: case study of Sulukule neighborhood in İstanbul
Hokmabad Ghoshouni, Samira; Barlas, Mehmet Adnan; Urban Design in City and Regional Planning Department (2018)
The rapid increase of population and urbanization as well as many other contextual factors has led to the urban decline phenomenon. Under rubrics such as urban transformation, the urban regeneration projects have been one of the widely and frequently utilized approaches, which perpetuated within the recent decades to cope with the phenomenon, and this includes both the developed and the developing countries. However, there always have been different arguments and criticism about the aim and the outputs of t...

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...
Experimental testing of hot mix asphalt mixture made of recycled aggregates
Rafi, Muhammad Masood; Qadir, Adnan; Siddiqui, Salman Hameed (2011-12-01)
The migration of population towards big cities generates rapid construction activities. These activities not only put pressure on natural resources but also produce construction, renovation and demolitionwaste. There is an urgent need to find out ways to handle this waste owing to growing environmental concerns. This can reduce pressure on natural resources as well. This paper presents the results of experimental studies which were carried out on hot mix asphalt mixture samples. These samples were manufactu...

The rapid pace of urbanization, coupled with inadequate measures of government policies, has led to detrimental consequences for the built environment, the economics of daily urban life, and the life quality of city dwellers. Urban Heat Islands (UHI) exacerbates resource consumption and environmental footprint and threatens human health and comfort. New design and adaptation strategies are needed for urban settlements not only to lower the energy consumption and environmental impact of the built environment...
Social housing as a solution for housing need of low-income: evaluation of housing implementations of housing development administration (TOKİ) for lower-middle income groups
Gülcan, Elifnaz; Uzun, Cemile Nil; Department of Urban Policy Planning and Local Governments (2020)
In the last century, after the industrial revolution, the migration from rural areas to urban areas has increased. Therefore, urban areas and urban poor have faced different problems. At that point regarding policies started to be established in order to meet the need of this vulnerable side of the society. The social housing policies increased after the Second World War in European countries with the raising of the welfare state trend in the world. Subsequently, after 1980 with the decrease in the state in...
