“…The control room indoor thermal condition is such that it did not meet the thermal comfort standard set by ASHRAE Standard 55 as well as ISO 7730. The hot room condition is in agreement with investigations by other local researchers such as Imran et al (2016[b]), Ibrahim and Tinker (2005), Rajeh (1994), Nugroho (2011), Kamar et al (2012) as well as Normah, Lau and Mohd Yusoff (2012). These researchers have shown that typical Malaysian residential house including low-income house have failed to provide the minimum thermal comfort target.…”

Night air temperature in Malaysia is generally about 23°C and is a potential source of heat sink to dissipate heat gain from a building. A thermal storage tank was used to store a certain quantity of water and was passively cooled during the night using the pitched roof as a heat exchanger to chill the water to as low as 22°C. The free cooling of water was then used as a cooling medium to cool the modular radiant cooling panel during the day time when the outdoor temperature exceeds 30°C. The experiment shows that the system was able to maintain an indoor temperature of less than 28°C when the outdoor temperature peaked to nearly 34°C while providing acceptable thermal comfort with certain controlled air movement. The use of the hydronic radiant cooling panel with free night cooled water as its coolant is proven to have significant energy saving potential of up to 85% while at the same time provide an acceptable room thermal comfort which meets the international standard criteria such as the American Society of Heating, Refrigerating and AirConditioning Engineers (ASHRAE) Standard 55.

“…The control room was seen as having failed to meet the thermal comfort limits set by ASHRAE Standard 55 as well as ISO 7730. This is in agreement with investigation by other local researcher such as [28,29,30,31,32] as well as [33] that have showed that typical Malaysian residential house including low income house failed to provide the minimum thermal comfort target. Study by [34] in a similar regional condition located in Sabah Malaysia have shown from a survey that the thermal comfort temperature was at 30.2 ºC.…”

“…everal pertinent studies have shown that the indoor thermal condition of a single-storey as well as double-storey terrace houses in Malaysia usually will exceed the recommended thermal comfort range as reported in [1] and [2]. The peak temperature is somewhere between 30 to 35° C in the afternoon which is beyond the thermal comfort range of between 28 °C to 31 °C at air velocity of 0.8m/s for natural ventilation in this climate condition [3].…”

Ground Air Heat Exchanger (GAHE) may be a solution to improve thermal comfort in buildings located in Sarawak but no ground survey specifically to examine the potential of GAHE has been done. Ground temperature prediction with computer program did not provide an accurate result for this region. In this study, a few sites with different soil profile in Kuching, Sarawak were selected to determine the soil temperature up to 4 meters depth. For peat soil area with high water table, the ground mean temperature is about 28 °C after 1m depth. For sandy clay type soil which is subjected to tidal activity, the daily soil temperature fluctuates greatly with the highest maximum temperature exceeding 32°C for all depth. This behavior is not really desirable if the ground were to be used as a steady heat sink source. Red podzolic soil gave an almost flat profile between 26°C to 27°C after the depth of 1m which is more desirable as a ground heat sink source. Therefore earth tube application in the state of Sarawak should consider the type of soil profile and optimum depth of to take advantage of the cool ground to provide building cooling.
