Study of Effect of Thermal Diffusivity on Ground Temperature for Malaysian Climate

Ground has been proven that it is able to supply cooling and heating resulting in significant reduction of electricity consumption. This paper discusses potential of ground towards implementation of ground thermal storage by using ground heat exchanger (GHE) to supply passive cooling for any applica...
