Case Studies

Guy's and St Thomas' undertake major air conditioning inspection project

To meet its air conditioning obligations under the European Performance of Buildings Directive (EPBD) Guy's and St Thomas' Hospital Trust required a comprehensive inspection of its air conditioning system.

The system comprised of a variety of cooling and ventilation systems serving 30+ buildings, on two sites, and included over 200 air handling units, 400 packaged units and two BMS systems.  The cooling equipment ranged from older R22 plant to more modern 407C centrifugal and absorption chillers.

The resulting detailed recommendation report revealed scope for major efficiency savings, equipment upgrades and recommended remedial work. As well as ensuring full EPBD compliance, potential savings worth up to £3m per year were identified.

“This was a major project to undertake, requiring experts in their field and a sympathetic approach to ensure minimal disruption to the operation of the hospital.  I’m pleased to be able to say that the Energy Consultants from Green Compliance more than met the challenge.  We hope to be able to work with them when implementing the programme of energy and cost saving projects.”

BAA uses Green Compliance for Energy Performance Assessments

As part of a drive to reduce its carbon footprint, BAA asked Green Compliance to provide energy performance certificates and advice for office units at its Southampton facilities.

Attention then turned to planning and prioritising improvements for energy efficiency and we look forward to helping BAA boost its green credentials.

"Green Compliance have delivered a fantastic service. They were flexible, prompt and very professional. The surveys took place with minimal disruption to our business partners at the Airport, and the results were provided soon after. They gave excellent follow-up expert advice to the Property, Engineering and Environment Managers on how to improve energy efficiency on site. I would highly recommend their services to other commercial businesses."
