Telehouse North Two Presentation 2015 - Adiabatic and Evaporative coolingTelehouse Europe
Telehouse is expanding its iconic Docklands Campus to include North Two - Europe’s most advanced data centre. Available from quarter 1, 2016, Telehouse North Two clients will be part of Europe’s leading connectivity hub with access to an unparalleled 73,400 sqm of space, with 532 carriers, ISP’s and ASP’s flowing into its Docklands campus. This presentation focuses on the industry leading implementation of our adiabatic and Evaporative cooling system.
Modelling Natural Ventilation in IES-VE: Case studies & Research OutlookDaniel Coakley
Presented at Technical Seminar: Ventilative Cooling & Overheating Risk - Cork Institute of Technology, 20th April 2016
This half day seminar for researchers, designers, engineers & architects, is organised in collaboration with IEA-EBC Annex 62 and will present state of the art in utilising ventilation for reducing cooling energy demand and addressing the risk of overheating in low energy buildings.
The presentation focuses on natural ventilation modelling features in the IES-VE Virtual Environment and case study of the application of some of these features as part of the ASHRAE LowDown ShowDown Competition 2015.
There are many opportunities to reduce energy consumption in existing commercial buildings. With some minor adjustments and changes it’s often possible to reduce energy bills by up to 15%. Further reductions can be made through capital improvements involving upgrading walls, windows, roof, HVAC equipment, lighting and domestic hot water systems. This presentation will review the process of evaluating the potential of energy saving opportunities and look at how they are typically implemented in buildings. Case studies of example projects will be presented. We will also highlight grants and incentives that are available to help offset the costs of these upgrades. And we will provide an overview on how retro-commissioning ties into LEED-EB and an explanation of the related pre-requisites and credits.

CEE and Seventhwave lead a rapid-fire discussion of innovative tech and program approaches, and the most meaningful recent research findings for utility representatives, efficiency program implementers, and both residential and commercial field experts.
In a typical building base-load analysis will identify the server room, if one is present, at the top of the list of “out of hours” consumption. In recent years server rooms have been built nearly always with mechanical cooling. In many cases we find that the cooling plant is consuming as much energy as the servers.
David Green, Head of Workshops at the University of Cambridge, will present the Department of Engineering server room journey. He has transformed one of his large server rooms by using free cooling and cold aisle warm aisle containment and learnt a lot along the way.

On Wednesday 13 November 2013, Blake Lapthorn's climate change team hosted a green breakfast seminar. Guest speaker Keeran Jugdoyal, Mechanical Engineering Manager at Faithful+Gould, talked about the lessons his company has learnt about the end use of sustainable buildings.
What cost-effective options are available for building owners interested in reducing their building’s energy use? CEE's Director of Engineering Services, Mark Hancock, P.E., will discuss rooftop unit retrofits as a scalable energy-saving approach and recommend next steps.
This is the second in a series of 'Show and Tell' webinars from the Ofgem Strategic Innovation Fund Round 1 Discovery phase, covering the Heat projects.
Consumers need better access to low-carbon heating options which remain reliable and affordable in comparison to existing solutions. For many domestic, commercial, and industrial end consumers, heat comprises a considerable proportion of their energy bills.
There are a variety of technologies which could potentially contribute to heat decarbonisation. These include heat networks, electric and hybrid heat pumps, hydrogen, biofuels and others.
As examples, you will hear from SIF projects working on developing the gas networks to adapt to hydrogen, and electricity networks exploring the use of thermal energy storage as a source of flexibility.
The Strategic Innovation Fund (SIF) is an Ofgem programme managed in partnership with Innovate UK, part of UKRI. The SIF aims to fund network innovation that will contribute to achieving Net Zero rapidly and at lowest cost to consumers, and help transform the UK into the ‘Silicon Valley’ of energy, making it the best place for high-potential businesses to grow and scale in the energy market.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

• Enhanced filtration and air
quality monitoring
• Humidity limiting control
algorithm and web interface
• Fan updates and flow
dampers
• Low levels of equipment
failure
• Hosting from other
university departments
• Fire suppression
24. 24
Initial Results – Contamination and Server Failure
• Initially limited filtration, now extensive
and multi staged.
• Some visible dust and black
particulates.
• Basic analysis showed the particulates
to consist of dust, possibly pollen
particles and diesel engine exhaust
particulates.
• There has been a small number of fan
failures on servers but this is difficult
to directly attribute to the cooling
system.
25. 25
The Results – Reliability and Maintenance
• Initially maintenance was not
comprehensively scheduled
• Location - surprising amount of
large fibres caught by insect
screen in the Spring
• 3 monthly maintenance of the
equipment is required
• Routine ‘deep’ cleaning of facility
to ISO 7
• With internal installation room
cleanliness needs to be
maintained
26. Visibility of Building Performance - Energy Dashboard

• Visibility of actual building
performance.
• Digital signage.
• Encourage individuals to ‘own’
and take responsibility.
• ‘Buy-in’ now apparent in some
equipment purchases.
• Individual racks are metered
27. Engineering’s Data Centre electrical loads
• 300 MWh electrical base load
• Pre 2010 – 35% = Server rooms
• Now 2 x Data Centres and 23% of
base load
• Purchasing vs energy performance

Summary
• Evaporative cooling has resulted in
significant energy and carbon savings
• Second Data Centre in Engineering is
now also based on this technology
• Interest from academic and commercial
sectors
• Catalyst for good practice in terms of
energy and carbon reduction
• Option for hot air exhaust use in natural
