Building Specifications - Overview

Darling Park offers a suite of sophisticated services to meet the demands of today's tenant. It is important to understand that the installation of partitioning will, as a minimum, almost certainly cause alternations to the air conditioning, fire sprinkler system, and lighting layout. Careful attention to the modification of tenancies during fit out shall ensure that the level and quality of services is not compromised. Specific reference is made to air conditioning where tenant's complaints are invariably due to poor tenancy design and/or implementation.

AIR CONDITIONING AND CONTROLS

Supply and Return Air

The air conditioning system serving a typical floor consists of branch ducts from six (6) central plant air handling units (AHUs). Three (3) AHUs serve centre zones and three (3) AHUs serve perimeter zones. Each perimeter zone AHU serves one long side and one short side of the building. All AHUs are variable air volume (VAV) systems. The master temperature sensors for the perimeter system's VAV boxes are located on the perimeter columns and the temperature sensors for the centre system's VAV boxes are left in the ceiling space with a length of sensor cable to allow the temperature sensors to be drawn down into partition walls, and occupied space, during the tenancy fit out.

SECURITY SYSTEMS

Security access is controlled throughout the common areas of Darling Park by an electronic security access system using proximity card technology. Tenants are encouraged to install a system that has compatible card technology. This means the tenancy proximity access card can also be used for property perimeter and lift access. The provision and programming of access cards and time zones to control access to the tenancy areas is the responsibility of the Project Manager and/or the tenant. The Darling Park security access system has the capability of providing individual access control of each of the two fire stairs on a floor to allow inter-floor travel.
