CASE STUDIESCSUN

The four buildings, each spanning three or four floors, house 37 to 52 individual apartments for two to four students apiece. The solution specified by James Valiensi, P.E., LEED GA of P2S Engineering of Long Beach Called for each apartment building to have its own multiple-unit tankless water heater system, furnished by Noritz America. These eight units per building would furnish domestic hot water only, with a new and separate heat pump system handling the space heating.

The final rooftop assembly at each building consists of four pairs of Noritz NCC199 condensing tankless water heaters, mounted back-to-back in two rows onto a custom-made streel rack.
