Basements:
Ventilation was achieved by 1-(37 Kw)Supply air fan and 2-(37KW) Exhaust air fan. All fans operated in smoke mode as well as in normal operation. All fans were wired in Star/Delta.
Office floors.
Each level (base building) had 2-plant
rooms with 2-Floor water cooled package

assisted with 2-return air fans. The units

drives. The zoning of the floor were
achieved by the use of VAV's fitted with electrical duct heaters. As for the tenancy work each area had a ceiling mounted water cooled package air conditioning unit complete with electrical duct heaters.
