Good planning and design make it possible to achieve a pleasant microclimate in modern cities. Microclimate considerations play an important role in assuring the comfort of a building’s occupants as well as favourable energy performance of the building itself. Microclimate studies are essential in creating natural ventilation and help to improve quality and circulation of air around a structure. They also help to prevent the emergence of ‘heat islands’ and other unpleasant phenomena on the pedestrian level. The tools most often employed in this study are parametric study, wind tunnel testing and computational fluid dynamics (CFD). Factors such as the building’s shape and orientation, distribution of surrounding buildings, the spacing between buildings, materials used, and existing climate of the surroundings are all taken into consideration. The output of the study will include the evaluation of human comfort, thermal conditions and the year-round performance of the nearby surroundings.

Microclimate study uses various methods to deliver a strategy for designing a comfortable environment. In general, parametric study, Wind tunnel tests and computational fluid dynamics are the tools employed for this study.
Microclimate design requires all disciplines in a project to work together. Smooth relationship between disciplines and final microclimate design which address all design team concerns is the prime consideration for ESE and GWTS engineers.
The building shape, orientation, distribution of buildings, the spacing between buildings, materials used for buildings and roads construction and existing climate of the surrounding are some of the points considered in microclimate study. The output of the study will include evaluation of people comfort and performance of the surrounding in all months, the contribution of the building to the local environment and optimal design advice to achieve a sustainable microclimate.
