Data Centre Cooling Review for Cardiff Metropolitan University

“The Green Consultancy was approached to carry out a review of the University's existing data centre cooling plant with a view to providing a suite of costed options to upgrade the aging equipment in place. From the outset, I found the team to be very approachable, knowledgeable and professional in their approach to the task at hand and the review and report produced was detailed, robust and received very positively by the University. A follow up report requested from them was delivered in the same timely and detailed manner and I would not hesitate to recommend The Green Consultancy to other University's and public-sector bodies.”
