摘 要：The overall goal of the Ulaanbaatar School Buildings Thermo-technical Retrofitting Project was to demonstrate the heat energy savings that could be achieved through thermal insulation and heating system improvements at three school buildings. The selected buildings (School Nos. 79-1, 79-2, and 63) are located in ger districts of the Mongolian capital city Ulaanbaatar (UB), are not connected to the UB district heating system, and are heated with coal-fired heat only boilers. The buildings were determined to be structurally sound prior to the project, but they lacked adequate insulation and were in poor condition--there was frost on the insides of some classrooms during the winter months, roofs were leaking, floors lacked insulation, and there were significant cracks in exterior walls.
