IES Consulting performed LEED energy modelling for this 30,000m2 data center in Rosersberg, Sweden.

Key Facts

  • 44% Cost Saving 44%
  • 21.6% Energy Saving
  • 6 LEED Credits
  • Area: 30,000 m2

IES Consulting performed LEED energy modelling through ASHRAE 90.1-2007 PRM App.G for this 30,000m2 purpose-built data centre in Rosersberg, near Stockholm, Sweden. The data centre was targetting LEED 2009 NC Certification with IES tasked to assist in modelling and reporting the EAp2/EAc1 pre-requisite and credit.

Overall the project achieved 6 credits. The analysis on this data centre demonstrated an improvement of 44% in cost and 21.6 % in energy for the Proposed building relative to the Baseline building. 

The key reason for the savings observed in this project are associated with the efficient use of free cooling using a wet hybrid cooler to minimise chiller demands when ambient conditions permit. The Baseline building also benefits from free cooling but through the use of an airside economiser to maximise cooling loads. Reducing the cooling demand by increasing the outdoor air has however led to an increased humidification demand. As the Proposed design only provides the minimum amount of fresh air the humidification loads are significantly lower.

The 'Global ICT Center' facility, purpose-built for Ericcson, is positioned to enable large-scale modelling of live operator networks in order to test new products and solutions via a single virtual environment, supporting Ericsson to host 5G development under one roof.
