Fresh air supply is collected at roof level using vents in wall of plant room, The cool fresh air is supplied by mechanical ventilation via large vertical ducts adjacent to the atrium corridors. Branch ducts off the main vertical ducts supply the office areas raised floor plenums. Office occupants may adjust floor diffusers and open perimeter windows to avail of more fresh air. Double facade designed as a exhaust facade and also acts as a buffer for wind and city noise, the double facade allows staff to open perimeter windows during windy weather. Using displacement ventilation the stale exhaust air moves through permanent vents from the office areas to the plant room. Motor opening vents in curtain walling to let air out of offices in to double facade and brought back to plant room. The full height atrium has automatic opening vents to let air out. Summer Cooling: The main cooling is provided using a ground water heat exchange, via a closed loop of glycol fluid pumped through pipes embedded in the exposed concrete floors (Active Structure System). The pipes feed the heat pump, which is reversed during summer months. Atmospheric heat is absorbed from the fresh air moving over the exposed concrete soffits by the pipes and transferred into the ground water. Excess warm air in the atrium is vented out in to the atrium linked to the building management system (BMS). The air is let out by automatic opening vents at top of atrium. The outer glazed double facade has blinding's given shading from the solar gain. Winter Ventilation: The building uses a combination of mechanical supply and extract with a heat recovery ventilation unit during the winter months. Fresh supply air is collected at roof level using vents in wall of plant room. The cold fresh air is pre-heated by recovered heat from the building. The fresh air is then supplied by mechanical ventilation via large vertical ducts adjacent to the atrium corridors. Branch ducts off the main vertical ducts supply the office areas raised floor plenums. Office occupants may adjust floor diffusers and open perimeter windows to avail of more fresh air.Double facade designed as a exhaust facade and also acts as a buffer for wind and city noise, the double facade allows staff to open perimeter windows during windy weather.

Motor opening vents in curtain walling to let air out of offices in to double facade and brought back to plant room. The full height atrium has automatic opening vents to let air out. Exhaust air is expelled from the building after recovering about 60% of the ventilation heat with the HRV units. Winter Heating: The main space heating is provided using a ground water heat pump, via a closed loop of glycol fluid pumped through pipes embedded in the exposed concrete floors (Active Structure System). The pipes feed the heat pump, which exchanges heat to the embedded pipes. Additional heat is transferred to the supply fresh air moving over the heated concrete structure in the floor plenums, thus further distributing the heat to the offices. Operable windows at the top of the atrium are closed during the winter, linked to the building management system (BMS).

Summer Ventilation:
The building uses a combination of mechanical supply and natural extract during the
summer months. Fresh air supply is collected at roof level using vents in wall of plant room,
The cool fresh air is supplied by mechanical ventilation via large vertical ducts
adjacent to the atrium corridors. Branch ducts off the main vertical ducts supply the office
areas raised floor plenums. Office occupants may adjust floor diffusers and open perimeter
windows to avail of more fresh air. Double facade designed as a exhaust facade and also
acts as a buffer for wind and city noise, the double facade allows staff to open perimeter
windows during windy weather.
Using displacement ventilation the stale exhaust air moves through permanent vents from
the office areas to the plant room. Motor opening vents in curtain walling to let air out of
offices in to double facade and brought back to plant room. The full height atrium has
automatic opening vents to let air out.

The main cooling is provided using a ground water heat exchange, via a closed loop of
glycol fluid pumped through pipes embedded in the exposed concrete floors (Active
Structure System). The pipes feed the heat pump, which is reversed during summer months.
Atmospheric heat is absorbed from the fresh air moving over the exposed concrete soffits by
the pipes and transferred into the ground water.
Excess warm air in the atrium is vented out in to the atrium linked to the building
management system (BMS). The air is let out by automatic opening vents at top of atrium.
The outer glazed double facade has blinding's given shading from the solar gain.
