fficient Air Ltd was set the challenge of
inspecting the air conditioning system at a UK
government building to show the value of such
inspections in improving efficiency at low cost.
The building, Eland House in London, is home to the
Department of Communities and Local Government
(CLG). We found that the savings identified for the

property in effect paid for the costs of the inspection
and recommendations in a short period.
In figures, the cost of the air conditioning survey was
£3,744, and the low-cost actions taken cost £8,200.
The payback period of the actions was less than five
months, and overall savings made came to a total of
£32,642.
When we carried out the inspection, the property had
a Display Energy Certificate (which covers operational
energy efficiency) with an F rating, one grade above the
lowest grading of G. CLG was keen to test whether an
