1350 Broadway:
New
a) Building standard VAV air handling unit (AHU) with chilled water coil and associated low and medium pressure ductwork with VAV boxes. Constant volume control will not remain. Remove and replace all air-cooled DX units with chilled water VAV AHUs. b) Provide an energy recovery ventilator (ERV) on outdoor air and exhaust. c) Provide modulating electronic control of existing steam radiators through VAV controllers and tie into base building BMS. d) Supplemental cooling shall be provided by exhaust fans where cooling load permits. If there is a need for more cooling than an exhaust fan can provide, an air-cooled DX unit may be installed.
Renewal/Retrofit
a) Building standard VAV air handling unit (AHU) with chilled water coil and associated low and medium pressure ductwork with VAV boxes. b) Existing to remain constant volume units must be converted to single zone VAV or multi-zone VAV systems as necessary for code compliance. Constant volume control will not remain. c) Provide an energy recovery ventilator (ERV) on outdoor air and exhaust. d) Provide modulating electronic control of existing steam radiators through VAV controllers and tie into base building BMS. e) Supplemental cooling shall be provided by exhaust fans where cooling load permits. If there is a need for more cooling than an exhaust fan can provide, an air-cooled DX unit may be installed.
1359 Broadway:
New
a) Air conditioning systems shall be air-cooled VRF with condensing units located in an appropriately insulated and waterproofed MER room within the tenant area. b) Provide an energy recovery ventilator (ERV) on outdoor air and exhaust. c) Provide modulating control of existing steam radiators through the VRF fan coil controllers or independent zone controllers and tie into base building BMS. d) Supplemental cooling shall be provided by VRF units.
Renewal/Retrofit
a) Any existing to remain constant volume units must be converted to single zone VAV or multi- zone VAV systems as necessary for code compliance. Constant volume control will not remain. b) Provide an energy recovery ventilator (ERV) on outdoor air and exhaust. c) Provide modulating control of existing steam radiators through independent zone controllers and tie into base building BMS. d) Existing supplemental units may remain until the suite is converted to VRF.
