Project:  Imagination Data Centre

Location:  Hemel Hempstead

M&E Contractor:  Derry Building Services

Completion Date:  June 2013

This new Data Centre was constructed for Imagination Technologies Ltd - a global leader in multimedia and communication technology. It houses up to 116 individual racks and a number of emulator test-beds.

The TREND Building Energy Management System (BEMS) controls all of the heating, ventilation, air conditioning and domestic services. Chillers and Computer Room Air Conditioning Units (CRACs) are integrated via Modbus networks and TREND TONN interfaces.

When external conditions allow, free-cooling is utilised, which gives a very low Power Usage Effectiveness (PUE) of 1.6. This is calculated by monitoring all of the Modbus electric meters, with live values and historic logging available to the client.
