Abstract: Electricity consumption in Singapore increases every year. There has been commendable efforts by the government to reduce the electricity consumption. These efforts are targeted at all aspects of the country. However, for the built environment, positive changes on strata-titled industrial unit will be limited even with government’s effort on sustainable buildings. Air conditioner in common area of these properties do not exist and owners have full autonomy of the interior of their units. This leads to the installation of air-conditioners in their premise because of the idea that fans are ineffective in achieving thermal comfort. Thus, this study seek to investigate and understand the effectiveness of electrical fans in achieving thermal comfort. An experiment on a randomly selected control and treatment group in a b1 industrial unit was conducted to investigate if the increase in air velocity through the employment of standing fans can help to achieve thermal comfort. Since thermal comfort can be both objective and subjective in nature, the PMV model was used by collecting data of measurable thermal comfort parameters and participants were required to answer a questionnaire. The subjective assessment found that all respondents from the treatment group were satisfied with the increase in air velocity and reported being comfortable in the unit. The objective assessment see PMV score improved when air velocity increases. This means that fans are effective in achieving thermal comfort. Future studies should look into the impact of increased air velocity on other parameters and further investigate participant’s sensation of the thermal parameters.
