The story
Baseline to verified result.
Baseline
A high-occupancy training space with demanding thermal comfort requirements, benchmarked against a conventional AHU and VAV configuration.
Engineering diagnosis
Conventional air distribution would over-supply the whole volume to condition the occupied zone, carrying a fan energy penalty for comfort nobody was in a position to feel.
YITAC scope
Twelve PDC coils sized for a 91.2 kW cooling load, with one primary AHU delivering 2,000 cmh of fresh air.
Verified result
Comfort maintained across the occupied zone with a materially lower connected load than the conventional comparison — measured, not modelled.
