between the front of stalls and the common passageway, double channel and grating for the drainage system to reduce chance of blockage, drainage traps at appropriate locations, floor slope extending from the interior of stalls to the front drainage channel, etc.
(9) Ventilation-due to poor ventilation, our markets are hot and humid especially in the summer. Mr. Chung Shu-kun mentioned the importance of ventilation earlier. I think we must introduce advanced ventilation systems to replace the old and out-dated system which can only lower the temperature inside the market by 2 degrees. Our society is progressing day by day and we need to improve our market facilities. So, I support the installation of air-conditioning in our markets. The problem can be resolved by the installation of air-conditioning facilities in the markets. At present, with our (M.E.A.T.) system, our markets are generally poorly ventilated, hot and humid and do not provide a comfortable environment for the public. It is clearly inadequate for ventilation purpose, given the large number of market-goers, estimated at 12,000 per day for smaller markets (such as Aberdeen Market) and 45,000 per day for larger markets (such as Ngau Tau Kok Market).
The following factors have to be considered:--
(a) The ceiling and the headroom of the market should be at a height lower than the existing one. However, the air-conditioning plant room would take up about 10% more space than the M.E.A.T. plant room.
(b) There would be higher recurrent electricity costs in the operation of air-conditioning plant, estimated at twice the electricity costs for the M.E.A.T. system.
(c) To recoup the recurring overhead expenses incurred in electricity, maintenance and repairs, the rentals for the market stalls may have to be appropriately adjusted.
(d) There should be an air locking device screen installed at all entrances and exits of the markets.
(e) The poultry stalls will need to be separated from the main market, as the bad smell from such stalls will foul the air in the general and main market area. Moreover, the poultry may not be able to stand the daily changes in temperature, between the cold and air-conditioned environment of the day, and the hot and humid environment at night after the air-conditioner is switched off.
(g) In the over-crowded urban area, installation of air-conditioning for markets may affect the immediate neighbourhood, therefore, careful positioning of the air-conditioning plant and water scrubber system is needed to reduce nuisance to the neighbourhood.
(g) Allocation of resources for air-conditioning new and existing markets will have to be considered in relationship with the priorities in providing other Urban Council facilities.
