Sustainable heating, ventilation, and air conditioning systems, such as those that harness low-enthalpy geothermal energy, are needed to reduce collective energy use and mitigate the continued effects of a warming climate. Researchers use asymptotic expansion techniques to study the harmonic thermal response of vertical geothermal boreholes in such systems to sub-annual harmonic excitations.
