Abstract
A comment is made on the works that should be done in a recent consultancy project on reviewing the ventilation requirements for local buildings initiated by the Building Department (BD), Government of the Hong Kong Special Administrative Region (HKSAR). It is suggested that indoor air flow should be studied carefully for developing codes related to ventilation requirements for buildings. Local air speeds, turbulence, and their effects on thermal comfort are the key factors in determining criteria for providing better ventilation. Correlation relations among the key macroscopic design parameters and thermal comfort indices should be derived. Also, it is worthwhile to consider the application of computational fluid dynamics (CFD) as this technique is more feasible and relatively cheaper than other methods. The use of CFD to study natural ventilation in a small flat is illustrated. Further, research activities on indoor air flow at the Hong Kong Polytechnic University (PolyU) are briefly reviewed. It is pointed out that local higher education institutions such as the PolyU would be in a very good position to help BD on working out appropriate codes on ventilation requirements in buildings. Results from this study will be useful not only to the HKSAR, but to other sub-tropical countries as well.
