Abstract
In this work, the Complex Fast Fourier Transform (CFFT) method is introduced to predict the roof temperature and heat gain in the tropical country of Singapore. The cost-effectiveness of cool paint and roof ventilation are evaluated through life-cycle analysis. Cool paint and roof ventilation can provide annual cooling energy savings of 33-57 USD/m2 for the top-floor residential units. The payback period of cool paint is shorter than 2 months in unventilated roof and shorter than 6 months in ventilated roof. Both cool paint and roof ventilation are very energy-efficient and cost-effective in tropical climate.
