Setting the standard
Meeting our responsibilities
As the leading operator of carrier-neutral data centres in Europe, we are committed to excellence and setting the benchmark in our environmental strategy and quality standards.
Setting the standards for environmental best practice
We adhere to stringent industry standards, and we lead the market in environmental initiatives. Organisations choosing TelecityGroup demonstrate they are selecting an operator that puts energy efficiency and environmental management at the core of its business.
EU Code of Conduct for Data Centres
We have developed and adopted the EU Code of Conduct for Data Centres to ensure our existing data centres can deliver maximum efficiency. The Code is designed to provide best practice guidelines to reduce energy usage and improve energy efficiency in data centres.
Our data centres are certified to ISO 14001
TelecityGroup has achieved certification to ISO 14001, the international standard for Environmental Management Systems. ISO 14001 is an internationally recognised accreditation for organisations that demonstrate superior environmental management.
Member of the Green Grid
We have a history of industry collaboration, international engagement and best practice sharing through our membership of the Green Grid and other industry forums.
Carbon Trust Standard
We were the first data centre operator to achieve the Carbon Trust Standard for demonstrating a significant and ongoing improvement in carbon efficiency in the UK. This recognises our commitment to reduce our impact on climate change by cutting carbon emissions.
Carbon Reduction Commitment (CRC)
The CRC Energy Efficiency performance league table ranks over 2,000 organisations in the UK that consume more than 6,000 MWh electricity per year. TelecityGroup is ranked 103rd out of 2103 companies scored across all industries (i.e. better than 94% of companies ranked).
By being the first data centre operator to subscribe to this offer, TelecityGroup shows its ongoing leadership in exploring and adopting technologies which help minimise the impact of its operations on the environment and maximise energy efficiency in the data centre. EDF’s "Equilibre+" offer certifies that the equivalent of 21% of the electricity consumed by TelecityGroup in France will be generated from renewable sources of energy and guarantees a neutral impact in terms of CO2 emissions.
FTSE4Good is an index designed to objectively measure the performance of companies that meet globally recognised corporate responsibility standards. TelecityGroup's continued membership in the FTSE4Good index acknowledges the Group's commitment to responsible business practice.
Creating highly efficient environments
As a data centre operator we recognise that our main environmental impact comes from the power we use to run our facilities.
Please wait while the video loads
In order to reduce our energy consumption and cut carbon emissions, we use innovative technologies that dramatically improve the efficiency of data centre power and cooling including:
Power Usage Effectiveness (PUE)
Energy efficiency is central to our transparent approach to power charging. Our data centres are designed to achieve industry leading PUE at full design load and we pass the benefit (and lower power costs) derived from this efficiency directly to our customers.
Carbon Usage Effectiveness (CUE)
We have committed to reporting externally on a new carbon usage effectiveness measaure, which we believe is an industry first. CUE captures a combined picture of the energy efficiency of operations and the carbon intensity of the energy used. It encourages individual data centres to both improve the efficiency of its systems and procedures and seek out low carbon sources of energy.
Free cooling systems
Many of our data centres use free cooling systems, which enable significant savings when the external ambient temperatures fall below a certain level. Temperature and humidity set points are optimised to optimised to ASHRAE guidelines to maximise free cooling periods.
Thermal energy storage systems
Our Southeast AMS5 data centre has the world’s largest installation of Aquifer Thermal Energy Storage (ATES). ATES is an innovative thermal technology which utilises the naturally stored groundwater found in Amsterdam’s unique river delta-based geography. The system works in harmony with the seasons by storing water in underground wells which is warmed by waste data centre heat in the summer and cooled by the lower external temperatures in the winter. This cold water is then pumped up in closed circuit system and used to cool the data centre in the warm summer months.
Hot and cold air segregation
Hot and cold air is contained in separate aisles to reduce the mixing of cooled air and hot exhaust air in data center aisles. This reduces energy consumption as cooling is more efficient.
Re-using waste heat
We extract waste heat in many of our data centres to heat office space. In our Condorcet facility in Paris, waste heat is used in a greenhouse that has been constructed on one side of the data centre, which is operated by the French National Institute for Agricultural research.
Efficient lighting systems
Our data centres use motion-activated light controllers that reduce energy consumption and heat load.
Best practice advice
We have invested in technology that measures air and heat streams, which we use to advise customers on the most energy-efficient configuration of their equipment.
We have won a number of awards in recognition of our environmental leadership:
Stevie International Business Awards 2011
Distinguished Honouree for Environmental Responsibility
European Business Award 2011
Country representative for the Award for Environmental and Corporate Sustainability
