Established in 1989, Telehouse became Europe’s first purpose-built, neutral data centre provider by opening its famous London data centre Telehouse North. Headquartered in London, UK, Telehouse has since grown to become one of the largest, global data centre providers, operating a network of 46 data centres in 24 strategic locations in the EMEA, the Americas and the Asia-Pacific region that cover all major commercial and financial hubs, meaning that you are never too far from our premium data centres.
This presentation focuses on Telehouse North Two’s revolutionary cooling technology being installed know as adiabatic and evaporative cooling. This presentation was presented at Data Centre World 2015 by Mark Collins, Director at Excool, Andrew Dewing, Director at Telehouse and Malcolm Howe, Partner at Cundall.
INDIRECTLeverage natural cooling properties of outdoor air but keep contamination out. Outdoor air cools indoor air without direct contact.
ADIABTIC & EVAPORATIVEDecrease temperature of summer outdoor air by increasing moisture content.

• ‘Recommended’ and ‘Allowable’ refer to the environmental control envelopes recommended by ASHRAE TC 2011 Thermal Guidelines for Data Processing Environments • Based upon 1MW IT load running at an annualised average of 75%• Data Source ASHRAE weather data viewer 4.0• Supply temp 24°C, return 36°C. Supply temp allowed to rise to 27°C (recommended) and 32°C (allowable).• Aisle containment in place maintaining a 12K ΔT between supply and return.• Resilience based on N+1 and pPUE calculated with all units running.• pPUE = (Cooling input power + IT power ) ÷ IT power
Key observation – PUE of ≤ 1.15 achievable in many locations

Newly developed emergency water save mode reduces stored water requirement by a further 30%
Site Context
• Telehouse has operated at East India Dock since 1990, close to Canary Wharf and the City of London.
• Major connectivity hub for the UK
• Significant power available via our own 132kV substation and the 11kV local utility.
• Adjacent vacant site offers opportunity for further development of the Telehouse campus
Opportunity for Expansion was too Good to Miss!

Introduction to Telehouse North 2 Project
Highly developed , tested and independently verified control strategies.
Newly developed emergency water save mode reduces stored water requirement by a further 30%
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.

TN2 - High Level Requirements
Highly developed , tested and independently verified control strategies.

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!

TN2 – CFD Study of Plant Gantry
Highly developed , tested and independently verified control strategies.
Key Challenge – Operation of Evaporative cooling system:
• Localised increase in wet bulb temperature caused by rising plume of moist air.
• Risk of De-Rating IAC units serving Upper Floors.
• CFD analysis to study air movement patterns under ‘still air’ conditions.
• Optimal solution to completely segregate intake and discharge airstreams.
TN2 – Building Form
Key Challenge – Retro-Fitting of IAC Units onto External Gantry:
• At Day 1, IAC Units will only be Installed on Floors 6 and 7.
• Robust strategy needed for installation of future IAC units, as progressive floors are fitted-out.
• Optimal Solution to hoist IAC Units up inside Gantry from temporary platforms constructed at each end of the building
