Microclimatic Impacts and Human Comfort Condition of Large-Scale Urban Park in Dhaka City at Summer Time (Mid-April to Mid-July): Mirpur Botanical Garden Park as a Case Study

Urban parks are of paramount importance in ensuring the availability of green spaces and the improvement of the overall quality of life in highly populated urban areas. The complex surface structure of urban parks generates an environment with distinct microclimatic characteristics. They influence the use of outdoor spaces, particularly in scorching and arid regions. The present work aims to investigate the climatic condition and climatic factors (temperature and humidity) of the park during the peak summertime. It also intends to examine the level of comfort experienced by users in an urban park located in Dhaka city. The project comprised of measuring the climatic factors (temperature and humidity) from various locations (natural and built-up area) inside the park. The investigation also included a subjective survey with queries about the perceived level of user comfort. The current apparel of individuals and the peak visitation time of day were also recorded. GIS, SPSS, Microsoft Excel, and other tools were used to analyse the research data. Results reveal that the park has “Hot Spots,” “Cool Spots,” and a “Moderate Spots,” making garden temperature swings easier to explain. Also, the botanical garden’s lower-temperature zones have excellent human comfort ratings, indicating a pleasant and satisfying experience. The study shows how microclimatic factors affect park design and provides a roadmap for improving urban parks. Greenery and cooling may make metropolitan communities healthier and happier in the park. This research attempts to lessen urban heat island impacts through park design and improve community vitality.
