Summary
A 43-day summer field campaign tested a building cooled by buried air ducts working with a collector-boosted solar chimney. In natural mode the system cooled the space with no electricity and gave more comfortable indoor conditions than fan-driven operation. A week of forced flow warmed the ground and cut cooling output, and the soil needed more than two weeks to recover.
