DESIGN FOR OUTDOOR THERMAL COMFORT

Abstract

A standout amongst the most significant effects of urbanization in Indian urban areas is the change of green belts and agribusiness land into the developed zone in the fringe (Chadchan and Shankar, Int J Sustainable Built Environ 1:36–49, 2012; Pandey and Seto, J Environ Manag 148:53–66, 2015). In this way, significant issues are related with fast advancement, for example, extra framework, casual settlements, natural contamination, demolition of biological structure and poor air quality. With these physical changes there is decline in green spread and increment in developed, the land surface temperature (LST) will undoubtedly increase. Gurugram is one such example of explosive urbanization, which is accommodating thousands of migrant beyond its stretch hence transforming the natural built environment. This study will focus on the relationship of urbanization and its consequences on land use and land cover and how is it affecting the local environment and human health in terms of air quality, it will also identify the relationship between LULC, LST and air quality using ERDAS IMAGINE ARCGIS 10.3.and RAYMAN software. The present study aims to analyse the association between built-up, green cover and land surface temperature for which district-level analysis of the Normalised differential built-up index (NDBI), Normalised differential vegetation index (NDVI), and land surface temperature (LST) has been done over the urban area of Gurugram. In this and Landsat 8 (OLI/TIRS) for 2018 have been used together with Air quality Real time data. Indices like NDBI, NDVI, LULC and LST are calculated for 1998, 2010and 2018. The study showed that NDVI and LST are negatively correlated with each other as vegetation has a cooling effect on the land surface temperature whereas NDBI and LST are positively correlated with each other. The studies show a change in the distribution of vegetation cover and gradually increase in the built-up land which results in the increase in land surface temperature over last 10 years. Further, green strategies are proposed to mitigate the effect of temperature and. These green infrastructures can be in the form of a patch or network of patch.
