Description

Ben Ali and co-authors model a cooling system that pipes air underground before it enters a building, in a 2025 paper. Earth-air heat exchangers use the soil's steady temperature to trim air-conditioning loads. The team tested how pipe shape, burial depth, and wall thickness shape both cooling power and cost.

Rectangular pipes cooled best, reaching eighty-five percent efficiency and cutting air temperature by up to ten and a half degrees. Burying pipes four meters deep nearly doubled compressor savings compared with one meter. A fifteen-meter rectangular pipe buried three to four meters deep balanced savings, about thirty-eight percent, against a payback of under four years.
