Time-series variation of groundwater temperature in Mongolia shows that maximum temperature is occured from end of October to the first of February(inter time) and minimum temperature is observed from end of April to the first of May(summer time). Therefore ground temperature is s a good source for space heating in winter and cooling in summer. Groundwater temperatures monitored from 3 alluvial wells in Ulaabaatar at depth between 20 and 24 m are (4.43±0.8)℃ with average of 4.21℃ but mean annual ground temperature(MAGT) at the depth of 100 m in Ulaanbaatar was about 3.5~6.0℃. Bore hole length required to extract 1 RT’s heat energy from ground in heating time and to reject 1 RT’s heat energy to ground in summer time are estimated about 130 m and 98 m respectively. But in case that thermally enhanced backfill and U tube pipe placement along the wall are used, the length can be reduced about 25%. Due to low MAGT of Ulaabaatar such as 6℃, the required length of GHX in summer cooling time is less than the one of winter heating time. Mongolia has enough available property, therefore the most cost effective option for supplying a heating energy in winter will be horizontal GHX which absorbs solar energy during summer time. It can supply 1 RT’s ground heat energy by 570 m long horizontally installed GHX.
