Award winning building management from Cylon

The office space at One Hanover Street is approximately 70% open plan and 30% cellular and fully air conditioned under the control of a Cylon Building Energy Management System.

One Hanover street winner of both the London and National workplace categories in the British council of office awards is a prime example of how a successful building energy management system can provide award winning ambient office conditions.

Occupying an area of over 11,000 m2 (118,000ft2), the office space at One Hanover Street is approximately 70% open plan and 30% cellular and fully air conditioned under the control of a Cylon Building Energy Management System.

The building is the European headquarters of Apple Computers and also provides office and dealer space to Icelandic bank Kaupthing Singer and Friedlander.

Tenants occupying high quality office accommodation of this nature expect that a comfortable environment will be maintained at all times.

The Cylon BEMS monitors temperatures to within close tolerances.

Air conditioning to the office spaces is provided by two chillers, linked to a two-pipe fan coil system serving all of the office floors.

Tempered fresh air is provided by a rooftop air handling unit.

For most of the year, the inherent heat gains from office equipment and people mean there is no additional heating requirement.

When temperatures are particularly cold the Cylon BEMS activates electric heaters installed in fan coil units that are close to windows helping offset any heat losses.

Should further heating be required, the BEMS will switch on the gas-fired heater in the air handling unit to pre-heat ventilation air.

In order to ensure conditions are maintained and energy performance is optimised the building manager needs clear visibility of building conditions, with the ability to adjust key parameters.

Crucially, the Cylon system also makes it easy for Building Manager Otto Chacon to monitor and control the systems.

"Using the PC interface I can monitor parameters such as temperatures and on/off times and it allows me to tweak settings in some areas of the building to optimise energy consumption," he explained.

"It is also very easy and logical to use, which has enabled me to train the reception staff to use the system as well - for when I am not here," he added.
