“…With the developing satellite technologies, it is possible to determine the urban heat islands with the thermal sensors on the satellite (Orhan et al 2019). Today many studies are investigating the relationship between urban land use/land cover and urban heat island (Herbei et al 2012;Patil et al 2018;Khorrami et al 2019;Kuşak and Küçükali 2019). When these studies were examined, it was observed that generally similar results were obtained.…”

Land surface temperature (LST) Urban heat island (UHI) Normalized differential vegetation index (NDVI) Bursa Today, industrialization and urbanization in large cities cause an increase in the surfaces covered with man-made objects such as concrete and asphalt. The expansion of urban areas and increase in the using materials with high heat storage properties, directly affect the Land Surface Temperature (LST), which shows an increase in the sensible temperature of the region. LST is directly connected to the natural green vegetation of the land and varies widely in large urban areas, these differences related to the temperature is defined as the 'urban heat island'. In this study, it was investigated the temporal variation of land surface temperature due to urbanization. Bursa, which is considered as a study area, has shown a rapid population increase since 1990 and a rapid increase in the number of buildings with the impact of urbanization and industrialisation. To determine the effect of this urbanization and industrialisation on land surface temperature, temporal change analysis of the surface temperature in the Bursa was observed with Landsat satellite images of 1988, 1998, 2008 and 2018. From produced maps, it was observed that the amount of green vegetation in urban areas decreased and as a consequence of this decrease, the surface temperature increased in the urban areas.

“…For the purposes of this study, the LST calculation method created by Shen and employed in the prior study (Kusak & Kucukali, 2018 ) was preferred. In this case, emissivity values of 0.9923 are approved for water areas, 0.923 are allowed for urban impermeable and bare soil regions, and 0.986 are accepted for plant areas.…”

Artificial impermeable surfaces are becoming more prevalent, especially in urban areas, as a result of shifting land use and cover, roads, roofs, etc. The modification of land surface temperature (LST) can also be accomplished through artificially impermeable surfaces. Large artificial impermeable surfaces, such as rooftops, parking lots, and other areas of use, can be found in industrial zones, shopping malls, industrial airports, and other locations. For the Anatolian side of Istanbul, 14 Landsat 8 OLI/TIRS imagery images over the years 2016–2022 were investigated. To evaluate how well the study’s images could be utilized, correlation and cosine similarity approaches were employed. A total of 12 images may be employed for research LST studies, it was discovered. We looked at closure dates during the COVID-19 epidemic to find out how human migration affected the LST. In addition, the LST value was estimated using the ordinary least squares (OLS) method employing LST and other biophysical indices. A decrease in LST values was seen as a result of the investigation. High levels of similarity and correlation were found between the images used. Results from the Google Mobility Index also provide support to the study. All of these facts provide support to Istanbul's Anatolian side experiencing lower surface temperature values, which consequently affects the city's massive structures.

“…If FB <DB, then the shading of the building exposed to the sun is formed in the neighboring garden area or the back-garden area between the neighboring buildings (Arumi-Noe, 1996; Data, 2001;(Kuşak and Küçükali, 2019)).…”

“…In Turkey, because summer days are long and the weather is too hot, shady places are desired for getting rid of the sun's overwhelming effect. In order to ensure that buildings or open-air rest areas are kept in the shade, they can be designed with buildings or recreation areas at the planning stage (Kuşak and Küçükali, 2019;Ekercin et al, 2019). Positioning the specified spaces in the maximum amount of shade is closely related to the location of the buildings, the distance between the buildings, the sun's azimuth angle and the solar zenith angle, as well as the time of the day and the sun declination angle at that time.…”

Because summer days are long, and the weather is too hot, people desire shady spaces to escape the overwhelming effect of the sun. To keep buildings and open-air environments in the shade, a suitable building location design may be created at the planning stage. Positioning of buildings and recreation areas in the maximum amount of shade is closely dependent on the location of the buildings to be built, the distance between the buildings, the time of the day and the sun angles at a particular hour. It was found necessary to carry out this study, since no study was found to be carried out regarding the positioning of buildings in the maximum amount of shade. For buildings to be built in residential areas, separate or block arrangements are applied. This study discusses a building to be built on a reconstruction island in Adana in the Eastern Mediterranean Region of Turkey. First of all, the shading effects of the buildings adjacent to the building in a parcel were examined in detail based on various positions of the façades of the building and different values of the solar azimuth. As a result of the study, the positioning of the buildings for providing the maximum shading was investigated. If the front and rear façades of the buildings were located in the west-east direction, according to the positioning of the buildings in the north-south direction, the front and rear façades would be exposed to less sunlight and more shade. In h = ± 6 sun hours, the façades of buildings in the parcels facing the north were under the influence of the sun rays coming from the side, and the rear façades of the buildings were in the shade.
