Abstract—This research presents an investigation into the
performance of Earth Air Heat Exchanger (EAHE) in
Malaysian climate. The passive cooling technology, where the
ground is used as a heat sink to produce cooler air, it is an
emerging of area of interest in Malaysia. This system is an
important concept of sustainable design for Green House which
enhance energy saving and reducing of Green House Gases
emission. The aim of this study is to find the best ground cover
in improving the (EAHE) proficiency through thermal model
using computer simulation. The pipe which was used in thermal
model have same parameters of real case which were 3-inch
diameter and the material of pipe was PVC, the velocity of flow
air was 1 m/s, the pipe was buried in 4m depth and had 50m
length. The performance of the EAHE was simulated using
loam, clay, sand, silty clay, sandy clay loam as back fill material.
It was found that sandy soil is the best ground cover material.
Index Terms—Earth air heat exchanger, ground cover,
passive technology.
