“…Indian cities are concrete jungles, and with the increase in concrete volume, there has been an increase in the urban heat island effect (Anguluri and Narayanan 2017; Verma and Raghubanshi 2018;Widiastuti et al 2018). Unplanned urban development has increased the surface area which absorbs and retains heat from sunlight.…”

“…Unplanned urban development has increased the surface area which absorbs and retains heat from sunlight. This causes an increase in temperature, which in turn increases the energy cost to cool the interiors (Anguluri and Narayanan 2017; Verma and Raghubanshi 2018;Widiastuti et al 2018). Cooling the interiors increases the climatic temperature in the long term, thus causing a vicious cycle.…”

In the current Anthropocene epoch, globalization and urbanization have adversely affected our environment causing global warming. To counter the adverse effects of global warming, research is being conducted into many innovative technologies to identify viable solutions. This paper will focus on one such solution, Living walls and how the built form is enriched by the environmental and psychological benefits provided by Living walls. Buildings with Living walls have lively surroundings which enhance the urban fabric. This review paper shall elaborate on the effects of Living walls on the built environment in the urban realm and analyze how Living walls improve the urban fabric in terms of activity and behavior pattern, streetscape and building frontage.

“…LST and near-surface air temperature are thus not perfectly comparable [70,71]. Establishing a relationship between LST and near-surface air temperature is even more complicated in urban environments, where warming and cooling sources that are not detectable by satellites (e.g., anthropogenic heat sources, facade greening), and wind can strongly influence near-surface air temperature [72][73][74]. Similarly, the effects of changing material properties, such as heat capacity and heat conductivity, that strongly affect surface properties cannot be quantified, as material changes can only be estimated properly by in situ measurements.…”

Evaluating the Potential of Landsat Satellite Data to Monitor the Effectiveness of Measures to Mitigate Urban Heat Islands: A Case Study for Stuttgart (Germany)

The urban heat island (UHI) effect is a serious health risk for people living in cities and thus calls for effective mitigation strategies in urban areas. Satellite data enable monitoring of the surface urban heat island (SUHI) over large areas at high spatial resolution. Here we analysed SUHI in the city of Stuttgart (Germany) based on land surface temperature (LST) data from Landsat at 30 m resolution. The overall SUHI in Stuttgart decreased by 1.4 °C between the investigated time periods 2004–2008 and 2016–2020, while the absolute LST increased by 2.5 °C. We identified local hotspots of strong warming and cooling in Stuttgart through the change in SUHI and categorised them based on the predominant land cover change occurring at the hotspot using the Normalised Difference Vegetation Index (NDVI) from Landsat as well as visual information on land cover changes from Google Earth Pro. The establishment of green roofs, as well as albedo changes, are predominantly responsible for cooling spots, while warming spots are mostly associated with the sealing of surfaces. This highlights that vegetation has a dominant influence on SUHI development in Stuttgart. Combining satellite-based LST data with visual information thus provides an effective method to identify local warming and cooling hotspots, which allows monitoring of the success of city policies against heat stress and guides future policy.

“…As previously already mentioned, in this study, three field measurements with different leaves covered area were done on the building model, which was like a house miniature with a scale of 1:4 compared to an original building [15,19,20]. Details of the dimensions of the building model can be seen in Figure 2.…”

This project is part of research series to observe the thermal characteristic of green facade to minimize the cooling load inside building. The aim is to analyze the building thermal characteristic on the green facade installed on a building model. Various kinds of leaves covered area (experiment I: 0%, experiment II: 50%, and experiment III: 90%) were used as the main parameter. Calculation in decrement factor and time lag were also done in order to support the analysis of heat flows calculations. Data measurement showed that ambient and facade surface of green facade with the greatest leaves covered area (experiment III) had lower temperature profiles. Data calculation also showed the highest of average heat flows were found out in the bare wall model. Results for heat flow in the wall surface were 4.69 W/m2 (experiment I), 3.88 W/m2 (experiment II), and 1.61 W/m2 (experiment III). While for heat flows through indoor air space, they were 27.75 W/m2 (experiment I), −5.10 W/m2 (experiment II), and 8.99 W/m2 (experiment III). As shown from data analysis, the quantities of leaves covered area effected the cooling down on the building envelope by reducing the quantity of heat flows from exterior to interior side.
