As sustainability has become a vital element in building development, Muhammad Syukri Imran et
al., investigated the applicability of hydronic radiant cooling system charged with night cooled
water in combination with Earth Tube Heat Exchanger (ETHE) to cool down a residential building in
Malaysia. The hybrid system is found to meet the thermal comfort that building occupants desire and
improve the indoor operative temperature by using natural heat sink sources such as the night sky
and cooler ground. This allows the hybrid system to save 95% energy, as shown in a simulation. The
results of the study are further explained in this paper.
