An underfloor air conditioning system has been provided for a mixed-use development in central London. One Benjamin is a new address opposite the new Farringdon station with 43,562 square ft of office, retail, and residential space. The original air conditioning design specified four downflow units per floor, two supplying the rear zone of the building and two for the front zone. Each zone was split into two further zones; one supplying cool air towards the perimeter of the building (where it is needed more to combat solar gain), and the other providing warmer air to the central areas of the office space where there is less heat generated by the sun. |
