A method and system for the distribution of water in a high rise building is provided using a minimum number of piping risers. The system has a domestic cold water riser, and a domestic hot water supply riser and a return riser. At each serviced floor, a cold water supply main extends from the domestic cold water riser and a hot water supply main extends from the domestic hot water supply riser. On each floor at which riser pressure is higher than domestic use pressures, a valve reduces the pressure of the entire cold water supply main to domestic use pressures. One or more valves at each of one or more suites on the floor reduce the pressure of the hot water to each suite, leaving the hot water supply main for the floor at full riser pressure. Coupling fan-coils with chilled water supply and the full pressure domestic hot water provides an efficient piping system for both environmental controls and domestic hot water use. Regular and periodic circulation through fan-coils avoid stagnation of the domestic hot water supply.

A temperature conditioning system for a plurality of suites of a high rise building is provided utilizing at least domestic hot water circulated through tubing fit to a radiant wall in a suite for heating the suite. A hot water heating system in communication with a supply riser and return riser provides hot water at variable pressure to each of the multiple serviced floors. Hot water is cirulated through distribution mains to radiant walls in the suites at full riser pressure, while pressure reducing valves off of the distribution mains lower the hot water pressure to domestic service pressures at plumbing fixtures. Similarly, domestic cold water can be chilled and circulated through the radiant walls for cooling. Three-way valves at the radiant wall can alternately circulate hot water or cold water under thermostatic control.
