The efficient harnessing of geothermal energy for the heating and cooling of buildings requires extensive simulations to be carried out during the detailed design phase of a new building. These simulations, performed using semi-analytical models, serve to assess the thermal response of the geothermal heat exchanger during the building’s lifetime, that can easily excess 100 years. By using asymptotic expansion techniques, a new generation of theoretical models is being developed since 2011 that offer the flexibility and accuracy of the best performing models available nowadays, but at a fraction of their computational cost. These new models open the doors to yet untapped design and optimization possibilities.
