Canary Wharf, London, UK
PROJECT OVERVIEW
Canary Wharf is planned on a grand scale, yet with meticulous attention
to detail. The offices at Canary Wharf have been built to the highest
standards, set in a landscaped estate providing a relaxing and healthy
environment for office workers and visitors. The Estate extends over
86 acres. Some of the world's leading architects and designers have
been involved in its creation. The estate comprises:
- Ten office buildings (some incorporating retail units at street level).
- Multi level indoor shopping in Cabot Place East and Cabot Place West.
- A Docklands Light Railway station.
- A conference and banqueting centre.
- 17.1 acres of landscaped open spaces.
The Cylon Unitron BMS has been installed in various buildings within
Canary Wharf, including One Canada Square, DS5 Citygroup Tower and BP1
at Churchill Place.
BP1 is the newest project with some 92,900m2 (1 million sq ft), the building
is arranged over five basement levels, ground and 33 upper floors. It
includes a health and fitness centre for the BP1 staff as well as a 365-seat
restaurant and 100,000 square feet of training facilities. Five south
facing atria are stacked vertically maximising levels of natural light
in the office areas and providing a more relaxed informal working environment.
The Cylon Unitron BMS has been installed in all 5 basements and 33
upper floors controlling plant, with local temperature control via 2,100
UCU10VAV controllers on 1 basement and 23 upper floors. The BMS is managed
by a full time team of Eton Associates Engineers. The facility has achieved
an Excellent Environmental Assessment (BREEAM) rating.
SOLUTIONS BENEFITS
For the owners the new building provides a better working environment,
improved efficiency and significant environmental performance improvements.
The Cylon Unitron BMS controls local temperature and electrical supply
management and the facility has a range of features to cut down on energy
use. Benefits include:
- Centralised management of 24 floors of commercial office space
- Highly controlled comfortable working environment suitable for this
world headquarters
- Energy saving through efficiently managed ventilation, cooling and
heating
- Intelligent load shedding providing security of supply for critical
plant in the building
- Fast system trouble shooting through centralised alarm and supervisor
control
CYLON SOLUTION
The main function of the Unitron BMS in the BP1 building is controlling
the local temperature via the 2,100 VAV controllers on site. Energy
is saved by delivering only the required amount of air into each controlled
space. When each space does not have a cooling requirement the system
automatically drops the fan speed further reducing the energy required.
Each floor of the building hosts 16 multiple time zones which allow
the flexibility of enabling every fan assisted terminal unit box to
be changed to a specific time allocation. The Cylon OSNodes provide
a high level interface with the Chillers. With 6 Chillers and 9 Cooling
Towers sequenced to achieve rotation for numerous zone applications,
if one chiller shuts down, the BMS actions another to power up and single
point failure is prevented. The Unitron BMS manages a load shed routine
throughout the whole building. In the case of power failure the system
will shut down non essential plant to match available supply. Likewise
the system constantly monitors maximum demand and will intelligently
shed load so as not to incur penalties from the utility provider.
