Solar radiation overheats the roof and causes thermal discomfort for occupants throughout the day. Room air-conditioners are used to improve level of thermal comfort. However, air-conditioners consume high amounts of electricity. Insulation can retard heat flow due to their high thermal resistance. Yet, developers and the public are not aware of the benefits of insulation and are unprepared to implement them. The purpose of this study is to optimize thermal insulation in residential roofing system in hot-humid climate for maximum reduction in cost and CO2 emission. A questionnaire and interview were conducted to determine levels of awareness and preparedness and barriers among house owners, developers and professionals on the implementation of building insulation in Malaysia. Results reveal that the level of awareness on building insulation is generally low. The level of preparedness is high among house owners but low among developers because of the lack of appreciation towards the long-term benefits of housing insulation.
