The Consumer Council of Hong Kong recently released a report assessing competition in the domestic water heating and cooking fuel market. In this paper, based on Walls (1995), the author provides provide an objective view of this fuel market. An alternative organisation for the gas fuel industry is suggested that would promote competition without the introduction of a regulatory commission.

Filter Performance

For the purpose of reducing occupants’ exposure to micro-particulates, air filtration has been widely used in air-conditioned buildings. This paper proposes a practical procedure to evaluate the filter performance of window-typed air-conditioners on removing micro-particulates (PM2.5). Five residential apartments fitted with air-conditioners in the bedrooms were investigated. The site investigation involved, operating an air-conditioner at two different settings of normal filtration; additional filtration scenarios were operated for comparison, as well as one off-mode measurement. During the measurement, concentrations of particulates and tracer gas were monitored simultaneously. Based on the decay profiles of PM2.5 and tracer gas, the performances of air-conditioners at normal and additional scenarios monitored in the five apartments were within the ranges of 1.7–3.0% and 11.9–23.3%, respectively. The performance of additional filters was about 7.6 times more effective than the normal filtration.
