This month’s Facility File will focus on the B2B March test for the retrofit of a 1960s, 250,000-sq-ft hospital conversion to apartments changing out the high-pressure steam boilers to hot water boiler modules. The existing system had a pressure reducing station taking the steam from high pressure to medium pressure down to low-pressure steam that served multiple steam-to-hot-water heat exchangers, which in turn served the building heating system.
The scope of this building program is to remove the antiquated high-pressure steam boilers, steam piping, condensate return piping, pressure-reducing stations, deaerator set, and condensate pump sets. The energy retrofit portion of the building program is to furnish and install a series of high-efficiency, hot water condensing boilers and remove the steam-to-hot water heat exchanger installations.
