The Geo-Heat Center conducted a life-cycle cost analysis for various heating, ventilating, and airconditioning (HVAC) systems for the proposed new office building on the Winnebago Reservation in northeastern Nebraska. Three HVAC systems were considered: (1) rooftop units with gas heat and direct expansion (DX) cooling (air-cooled condensers), (2) air-source heat pumps, and (3) geothermal heat pumps (GHPs).


A geothermal district heating system has the potential to offer substantial benefits. The primary benefit is a stable energy price for a long period of time. Other benefits include the potential for a competitive price, use of a renewable, non-polluting, resource plus quiet operation. Further, the Pueblo of Jemez could achieve a measure of energy selfsufficiency and retain […]

Geothermal Feasibility Study

Previous analyses have suggested that the amount of thermal energy available for Enhanced Geothermal System (EGS) development is enormous. However, these earlier works did not use detailed geologic information – and, as a result, the methodologies employed and resulting resource estimates 2­3 were, by necessity, somewhat simplified.

There are several State and Federal incentive programs for geothermal heating and cooling systems for new and retrofit commercial buildings.  These incentives can amount to over 50% of the fully installed cost over the first five years.  Commercial incentives can appear a bit complex at first glance but their implementation is fairly straightforward once you sort it […]

How to avoid the pitfalls in sizing a Geothermal heating and cooling system for your home. The accepted method of sizing any heating or cooling system, especially when installing a geothermal heating system for your home, is to have a competent person do a heat loss for heating requirements and heat gain for cooling requirements.
