Air Ventilation Assessment System for high density city: An experience from Hong Kong
Refereed conference paper presented and published in conference proceedings



摘要Hong Kong was hit by Severe Acute Respiratory Syndrome (SARS) in 2003. The Hong Kong Government then set up a Team Clean Committee to critically examine the city for healthy living. The Planning Department, HKSAR initiated a study titled: "Feasibility Study for Establishment of Air Ventilation Assessment System". The study eventually led to a methodology of Air Ventilation Assessment (AVA). Unlike many countries with guidelines for dealing with strong wind conditions, AVA is a guideline for weak wind conditions specifically designed to deal with congested urban conditions. The AVA basically establishes a method for project developers to objectively assess their designs. The Government of Hong Kong adopted the system, published a Technical Circular in 2006, and implemented the system with the following note: "In accordance with the Joint Housing Planning Lands Bureau (HPLB) / Environment Transport Works Bureau (ETWB) Technical Circular No. 1/06 on Air Ventilation Assessment, all major government projects falling within the categories specified in the Technical Circular are required to undertake AVA." The government also set up an AVA project register. This paper reviews the experience learnt with the completed AVA project studies. It provides an insight to guide further actions and studies that will led to version 2 of AVA.
