Recent building and environment have evolved to embrace green roof-top as a new standard. The otherwise inaccessible roof region is now often used as outdoor refreshment area for public enjoyment. Developers of building projects have increasingly thought of ways to weatherproof the environment, making human experience more comfortable through climatic control measures. However, climatic control remained challenging in certain open-space areas, in example where enclosure of roof area is illegal under green-roof guidelines. This research paper serves as an enabling towards microclimatic manipulations on open spaces of roof region, supported by knowledge of airflow profile. Developers would be empowered with knowledge to extend feasible climatic control measures on open areas of roof garden, which faces tight governance by governmental authority while dealing with outdoor communal area. The strategic locations of misting operations on sky rise gardens are seen to bring many tangible and visible benefits towards microclimate control in roof region. Its cooling effects have continuing benefits on improving street level air quality, mitigating urban heat island effect both on roof and street level. Beneficial outcomes complimenting national interest would be presented in the follow report.
