In 2014, Heathrow’s Terminal 2 Retail Fit-out Sustainability Project won the ‘Most energy efficient project of the year’ at the Environment and Energy Awards. This was for Discovery Mill’s approach and the work the Heathrow team collaboratively achieved with Heathrow’s retail business partners in reducing energy usage in T2 Retail. Predicted energy savings were assessed to be 17-24% compared to existing Terminal 5 operations, with additional direct savings for Heathrow through reduced central building plant consumption as well as reduced infrastructure costs.
