How Best to Exploit this Opportunity?
DC Design has moved on since our last project - Telehouse West. Customer demands now along the lines of:
• High efficiency/low PUE
• Flexible and scalable power requirements based on base design power density of 2kW/m2 up to bespoke High Density requirements.
• Flexible and scalable connectivity
Requirement for high resilience, high availability.
![Page 15: Telehouse north 2 presentation for dcw 2015 final](https://reader033.fdocuments.in/reader033/viewer/2022042817/55a7a5dd1a28ab9a198b47af/html5/thumbnails/15.jpg)

Highly developed , tested and independently verified control strategies.
Newly developed emergency water save mode reduces stored water requirement by a further 30%
Telehouse Requirements
• High rise solution required – because of plot size.
• Best in Class PUE < 1.2 (better than any CW solution and making best use of available power on site)
• Ability to serve HD requirements on all floors
• BREEAM Excellent rating
• Redundancy in components and systems
• No single points of failure
• Concurrently maintainable

TN2 – Cooling Solution
Highly developed , tested and independently verified control strategies.
Newly developed emergency water save mode reduces stored water requirement by a further 30%
Considerations:
PUE Target necessitates Outside Air based cooling solution. Direct or Indirect?
• Urban location, with lots of traffic pollution -Extent of filtration needed with Direct Air
• Need for full cooling back-up with Direct Air
• Roof allocated to ancillary plant for plant room cooling and specific High Density Cooling
Indirect does not have outside air issues and no need for back-up cooling system
Telehouse Preference for Indirect Air Cooling Solution!
![Page 17: Telehouse north 2 presentation for dcw 2015 final](https://reader033.fdocuments.in/reader033/viewer/2022042817/55a7a5dd1a28ab9a198b47af/html5/thumbnails/17.jpg)

TN2 – Project Brief
Highly developed , tested and independently verified control strategies.
Newly developed emergency water save mode reduces stored water requirement by a further 30%
The Challenge:
To develop a multi-storey, indirect air cooled data centre, providing sufficient capacity to deliver 2kW/m2 average load
To provide ancillary cooling system to deliver maximum possible High Density capacity
Best in Class PUE < 1.2
BREEAM Excellent Rating
Concurrently maintainable - Redundancy in components and systems, with no single points of failure.
Challenge to the Cundall Team was to provide the Solution!
