“…As an important part of urban green infrastructures, the function of urban green space is also related to the quality of the local environment and the health of the residents [1,2], and plays an important role in urban ecosystems, which can reduce greenhouse gas, regulate the urban microclimate [3], reduce energy consumption [4,5], and maintain ecological security [6,7], which are among a wide range of ecosystem services [8]. The cooling effect of urban green space is regarded as an ecosystem regulating service [9,10].…”

Abstract:The rapid changes of land covers in urban areas are one of major environmental concerns because of their environmental impacts. Such land cover changes include the transformation of green space to impervious surface, and the increase of land surface temperature (LST). The objective of this study was to examine the spatial variation of urban landscape composition and configuration, as well as their influences on LST in Suzhou City, China. Landsat-8 image was processed to extract land covers and retrieve LSTs that were used to study relationship between spatial variation of LST and land covers. The results indicated that there was a significantly negative correlation between mean LST and green space coverage along the urban-rural gradients. With every 10% increased green space coverage, the mean LST drop was about 1.41 • C. A grid-base analysis performed at various grid sizes indicated that an increase in the percentage of surface water body area has a greater cooling effect of the mean LST than a vegetation increase. The mean LST had a significantly negative correlation with both the shape and aggregation indexes of the green space patches. Our results suggest that the sustainable landscape planning of green space in a typical city with a large water area should include both the vegetation and the surface water covers. The increased percentage of vegetation and surface water covers had the greatest cooling effect on an urban thermal environment, which is one of the ecosystem services that green space provides. A dense distribution of green space patches with complex shapes should be considered in urban sustainable landscape planning for increasing ecosystem services.

“…Due to the above, it is observed that the UHI has a direct effect on the urban microclimate and the energy consumed to heat and cool buildings [18]. The magnitude of the UHI and its effect on energy consumption depends on many parameters, in particular, the excessive urban warming, the types and characteristics of the constructions under consideration, and the local microclimate [19][20][21].…”

Comparative Analysis of Two Urban Microclimates: Energy Consumption and Greenhouse Gas Emissions

et al. 2019

This paper presents a hypothetical and comparative performance of a 5 ton air conditioner (AC) operating in two zones in different urban microclimates for 25 days. One site represents a type of homogeneous planned urbanism and the other is a traditional heterogeneous zone. Air temperature data was collected and then processed using a linear regression model included in the operating manual of the AC in order to obtain their energy consumption. Results indicate that for an area with 500 homes, a traditional urban complex requires 12,350 kWh of electrical energy more than a planned zone (1.89%). This extra energy amounts up to $1180 and adds 9191 kg of CO2 to the atmosphere. The increased energy consumption has implications that increase the cost and environmental aspects of two urban microclimates, so that urbanization without planning is less friendly to the environment. In this sense, this study highlights the effects of urban microclimates on domestic electricity consumption from air conditioning. In addition, for a city with an arid desert climate, the variation in electricity consumption is associated with changes in the urban mosaic. The results found represent scientific evidence that can be used as a reference to establish public policies that could be incorporated into the local construction regulations, oriented to reduce the energy consumption associated with the use of air conditioning equipment.

“…The topic has also been studied in Thailand, e.g. using remote sensing technology from satellite imagery to assess the UHI in large cities where large changes in land utilization have occurred, including Bangkok [41][42][43][44][45], Chiang Mai [43,46], Songkhla [43] and Mahasarakram [16]. However, Nakhon Ratchasima has not been studied, despite its rapid urbanization and major changes in land utilization.…”

The relationship between land surface temperature (LST) and land use in Nakhon Ratchasima was studied using data gathered from three satellite images from Landsat-5 (30th January 1992), Landsat-8 (9 May 2016) and THEOS (17th February 2016). There were four categories of land use: built-up area, green area, bare land and water sources. The split-window concept was used to estimate the LST. In 1992, Nakhon Ratchasima city in Thailand comprised 47.76% built-up area, 37.45% green area, 13.19% bare land and 1.60% water sources. By 2016, the built-up area had increased by 23.04%, the green area had decreased by 16.66%, bare land had decreased by 6.81%, but water sources had increased by 0.43%. Moreover, in 1992 the mean LST was 25.43 C for built-up areas, 24.44 C for green areas, 24.97 C for bare land and 24.75 C for water sources. However, by 2016 the LSTs had increased for each category: 28.74 C for built-up areas (+3.31 C), 27.20 C for green areas (+2.76 C), 28.11 C for bare land (+3.14 C) and 27.72 C for water sources (+2.97 C). The findings indicated that the LSTs increased with the pace of urbanization and changes in land use. Linear regression analysis revealed that built-up land had a positive correlation with LST, where a 1% increase in built-up area increased its LST by 0.146594 C.
