Occupancy - The building has been designed to an occupancy level of 1 person per 10 sq metres in the assessment of the building ventilation and cooling load requirements.
The building is designed to incorporate plant rooms within the roof areas. All plant within the building has been fully updated but the position of the plant has not changed. This allows minimum disturbance to the existing building and optimises the distribution routes and provide good access for maintenance purposes. Services distribution is by means of dedicated vertical risers. Risers are incorporated within the structural constraints of the building to ensure servicing zones are kept to a minimum.
Cooling Loads - The air conditioned systems have been designed to include the following internal heat gains: Small Power 25 w/m² Lighting 10 w/m² Occupants 10 w/m²
Small Power
15 w/m²
1.2 Flexibility
