Inspections show poor state of ac

Inspections under the Energy Performance of Buildings Directive are exposing the poor state of air conditioning systems in the UK, according to the technical director of Cibse.


Hywell Davies said much of the air conditioning equipment inspected so far had been faulty.


He added that energy assessors needed to be aware of how this could create unexpected outcomes.


Building owners were often seeing that, against expectations, energy bills increased rather than decreased after inspections, because faulty equipment had been repaired.


“This outcome shows how energy assessors have to be very careful in how they sell the benefits of an energy assessment,” said Mr Davies.


“If the inspection report identifies faulty air conditioning equipment and that is subsequently fixed, users will often see an increase in energy use and bills. Assessors need to be careful not to say that inspections will necessarily cut energy use.”


The directive places an obligation on air conditioning owners to have any of their systems with an effective-rated output of more than 12kW regularly inspected by an energy assessor.
