During 2017, we performed a comprehensive heat supply calculation and study for the office extension building of "Achit Iht" LLC's branch factory located in Bayan-Ondur Sum, Orkhon province. To reduce heat loss, we drilled 8 boreholes a depth of 120 meters, 28.4 kW and 9.4 m. Using 2 kV ground-source heat pumps and solar collector vacuums, a combination heating system was installed.

As a result of reducing heat loss from the building and heating it with geothermal and solar energy, 116 tons of greenhouse gases will be reduced from the atmosphere and adequate oxygen will be saved for 489 adults.
