Thermal Performance

A high performance façade combined with an efficient system of cooling ensures that the design parameters are achieved and that comfort is maintained with efficient use of energy.

Cooling: The chilled water supply is provided by water cooled chillers and towers at roof level; chilled water is distributed from the roof to AHUs throughout the building. The main air-conditioning for the office accommodation at each floor is provided by two variable air volume (VAV) systems, each with a dedicated mixing/recirculating air handling unit (AHU) with supply air temperature control. Supply air is ducted to distribution boxes above the ceiling; return air is routed via the ceiling void plenum.

Fresh air ventilation: Fresh air ventilation is provided via four air handling units (AHUs) located at roof level. Each AHU is connected to a series of vertical ductwork risers and typically comprises of supply and return air fans, complete with attenuators and a rotary heat exchanger for heat recovery and thereby reducing the amount of active cooling required.

Electrical Services

Supplies to landlord's services (toilets, stairwells, circulation space, plant rooms, cleaners' sockets etc) are provided from distribution boards at each level.

Substations/Main LV Switchboards: An incoming 11 kV electrical supply is provided to the building from a Ring Main Unit on the Utility Network.

An HV Switchboard feeds Transformers: Distribution via LV Main Switchboards is by means of cables to tenant's distribution boards (small power, lighting and space provision for Data Systems / UPS distribution board).






Electrical Loads in Office Areas

To accommodate no more than the following loads:
Small power: 25W/sq m
Lighting: 15W/sq m (includes allowance for task lighting to supplement general office illumination levels of 400 lux in open plan areas) An allowance for fan tile units is included in the above electrical load rates.

Standby Generation

4 No. 1000 KVA generator sets provide 100% standby power. Fuel storage for approximately 7 days running time is to be provided.

Illumination Levels in Office Areas

The lighting comprises of recessed, modular fluorescent luminaries, with high frequency ballasts for the general office spaces. All office lighting is occupancy controlled by ceiling mounted movement detectors. The illumination of the offices will be in compliance with the CIBSE Code for Lighting and the system will incorporate daylight linking 400 lux average in open plan areas.

Security Systems

CCTV is provided covering all elevations on ground level, the main entrance and reception areas and the service and loading bays. Access control, intruder alarm detection systems are provided at ground floor entrances. Door frames between core areas and office areas are provided with are wire ways for tenants to install future intruder detection systems.
