IMPACT OF CITY GREEN ON SURROUNDING MICROCLIMATE
CASE STUDY: WARRI - NARRINDA AREA, DHAKA
Dhaka, decades of rapid population influx has led to demands for rapid urbanization. With increase in housing across the cosmopolitan, there is a demand for urban open space across various peripheries in the city. This research documentation encompasses the heat island of a central region in Dhaka city, the Warri–Narinda Zone. Through satellite data and field survey, attention has been placed on the cooling effect of city‘s Green Areas, Temperature and Humidity measurements during the day and night time. This research was conducted in the surrounding green areas of Warri-Narinda, the Baldah Garden, The Christian Cemetery and the neighboring households, avenues, and the Primary Road with flyover, secondary roads with mutual shading of build form. The cooling effect and relative humidity was recorded across various locations and the results indicated the cooling effects of city greens are remarkable not only at vegetated areas but also the surrounding built environments. This research aimed to explore the role of the Green Area on moderating the Microclimate, and to determine the impact of City Green Area on its surrounding micro climate in context of high density; and to find out the cooling effect depending on the types of existing trees in the region. From the field survey, temperature and humidity measurements show significant fluxes in the temperature through urban neighborhood.
