Comparative analysis of life-cycle costs of geothermal heat pumps and three conventional HVAC systems.

Author(s) : SHONDER J. A., MARTIN M. A., MCLAIN H. A., et al.

Summary

The paper shows that when capital, operating, and maintenance costs are considered for the presented application, geothermal heat pumps (GHPs) have the lowest life-cycle cost, about 15% lower than the next most attractive option. The GHPs also have the lowest source energy consumption and the lowest total pollutant emissions of any of the technologies considered. For this application, geothermal heat pumps also have a lower first cost than any of the other systems currently used for space conditioning in new schools.
