[1] The UFAD system takes advantage of the thermal plume and stratification phenomenon: the conditioned air is supplied directly to the occupied zone (OZ). The thermal plumes generated by the occupants and other heat sources introduce the ...
When it rains, it pours inside the apartments of a crumbling Chelsea building — forcing one resident to wear a helmet in his bathroom to prevent parts of the ceiling from hitting him.
