The hotel building used in this study is located in the Jinshan
District, Taiwan, geographically in the area of the Tatun Volcano
distribution. The geothermal layer in this area is near the land
surface and the sea; hence, the water source of this building
is provided by a mixture of underground water and sea water.
Therefore, the geothermally assisted air-conditioned heating
system was adopted to replace the early boiler heating system.
