GHAMA - Assessment of the use of Ground Source Heat Pumps (GSHP) in heating and climatization of the Military Academy (Portugal): Amadora Quartering case study


This Project was focused on the investigation of existing surface installations and their ability to withstand a geothermal intervention, more precisely a building that functions as a dormitory in the Amadora Quartering of Academia Militar (Portugal), evaluating the thermal loads that can be replaced by geothermal energy. Of greater importance was the feasibility study of the most suitable scenarios, considered, for a conceptual phase of a pilot geothermal installation. The feasibility study, in addition to evaluating the most favourable methodologies, also evaluates the investment needs, the ease of operation and construction, as well as the most important economic indicators in the typical evaluation of a project, such as the net present value (NPV) , internal rate of return (IRR), and return period (PR).

Therefore, this project:

• Demonstrated the potential of the existing low-temperature geothermal resource to maximize the energy efficiency of the chosen building in its heating and cooling.

• Was used to the dimensioning of the Geothermal Heat Pump system at a conceptual stage and evaluating from an economic point of view the feasibility of applying the system, compared to the traditional technologies used.

• WAs a demonstrative reference, in the installation of the same type of technologies in other Portuguese Military installations.
