These buildings use air conditioning units to provide comfortable
indoor temperatures and humidity levels in Thailand’s
tropical climate. However, most of them lack consideration of the
appropriate architectural design and building envelope materials
that would reduce their energy consumption. As a result, electricity
bills rise due to increased energy consumption due to higher
cooling loads. This research therefore aims to develop natural fiber
cement roof sheets with better thermal properties to reduce the
amount of heat that goes into a residential building, and also to
reduce energy consumption.
