Display Energy Certificates – do they work?

April 12th, 2010

Three years in to the Display Energy Certificate (DEC) requirements for public buildings the question is ‘have they now demonstrated an effectiveness in reducing energy usage?’

The core need for DEC has to be education of the building owners and managers towards the opportunities to save energy and improve efficiency. More and more of these certificates can now be seen with data showing energy usage over the years so in terms of broad eduction they must be working, but in terms of reductions can we be sure?

Are the implications strong enough to empower building managers to act when they get the new certificate each year or do they see this as a paper exercise to complete?
