No. I would say almost all new builds have individually controllable heating vs cooling. Some are WSHP, some are 4 pipe, some are air-based heat pump, some may be other technologies I'm not familiar with. But 2 pipe systems with fan coil units are effectively eliminated from new residential construction.
When did two-pipe systems stop being used in new construction?
