Energy Efficiency Audits

Optimising energy usage in a server room or datacentre environment can lead to large savings in electricity usage and a reduction in operational costs (OPEX). At Server Room Environments are certified energy efficiency auditors can carry out a complete energy efficiency survey of your facility to identify potential areas for improvement.

Server Room Energy Consumption

Optimising energy usage in a server room or datacentre environment can lead to large savings in electricity usage and a reduction in operational costs (OPEX). At Server Room Environments are certified energy efficiency auditors can carry out a complete energy efficiency survey of your facility to identify potential areas for improvement. Please contact us for this free service and let us know a convenient time and date for your survey.

We normally start an energy efficiency survey with a desktop survey. From copies of your most recent electricity bills we can identify the amount of electricity purchased for a given time frame and the relevant cost per kWh. This allows is us to identify trends and peak usage periods. It can help if we can know the size of your building’s LV incomer but if not we can find this out from your local District Network Operator (DNO). The local DNO may also be able to provide information on power quality and outages which help in identify not just energy efficiency issues but also how to improve operational resilience for your server room or datacentre facility.

Identifying the actual kiloWatts charged for per hour (kWh) is also a good starting point as knowing these figures allows both ourselves and our clients to track the improvements we identify and implement from day one. Efficiency improvements can be substantial dependent upon the age of the installed equipment.

Survey Scope of Works

When we are asked to review a server room or datacentre for energy efficiency savings we have a predefined approach:

  • A on-site meeting and walk through to gain a full appreciated of the site and project
  • Connection of energy usage metering points and recording over a 24hour, 7day period
  • Identification of ‘low hanging fruit’ in terms of immediate steps that can be taken to improve efficiency

Our energy efficiency experts can normally identify immediate improvements. These can include properly fitting floor and ceiling tiles and cover plates onto racks. In terms of server rack cabinets, a different arrangement of the hot-cold aisles and server utilisation can also show immediate benefits. Other savings may require the replacement of out-of-date technologies including older air conditioning systems and poorly loaded, transformer-based uninterruptible power supplies. Today’s air conditioners and UPS systems are typically around 25-40% more efficiency leading to a fast capital payback on new investments.

Renewable Power

Server Room Environments can also help with renewable power. We can help to source your power from renewable energy providers and generators. We also work with specialist partners who can provide on-site renewable power generation in the form of Solar PV panel and on-shore wind farms.
