The design of a flat is dictated by requirements of the building regulations in respect of provisions for natural ventilation and daylighting in bathrooms and kitchens. Building Regulation states that the prescribed minimum window area should be not less than 6.25% of the floor area of the kitchen. However, this requirement may not achieve suitable cooling in the kitchen, In this paper, Computational Fluid Dynamics (CFD) code is employed to model a typical kitchen of 3.2m¥2.6m¥2.9m with 42 different dimension of window area. It is found that minimum ventilation rate for achieving reasonable cooling as well as thermal comfort in the kitchen is 7.30x10−1m3/s and minimum window area is 23.33% of the floor area of the kitchen, which is higher than the prescribed minimum window area stated in Building Regulation.
