Having an air conditioning system inspected by an accredited air conditioning energy assessor is designed to improve efficiency, reduce energy consumption, operating costs and the carbon emissions of the system.
Why are air conditioning inspections required?
The person who controls the operation of the system, such as the building owner or manager, has statutory obligations and duties of care in the operation and maintenance of air conditioning systems. The inspections are in addition to the normal activities associated with the ownership and operation of air conditioning systems.
When are air conditioning inspections are required?
All air conditioning systems with an effective rated output of more than 12kw must be regularly inspected by an energy assessor.
The inspections must be no more than five years apart.
The regulations require the first inspection of the affected air conditioning systems to be carried out as follows:
For all systems first put into service on or after 1 January 2008, the first inspection must have taken place within five years of the date when the system was first put into service
For other air conditioning systems, where the effective rated output is more than 250kW the first inspection must have taken place by 4 January 2009
For other air conditioning systems, where the effective rated output is more than 12kW the first inspection must have taken place by 4 January 2011
What does an air conditioning inspection cover?
The inspection will examine the refrigeration and air moving equipment that are part of air conditioning systems and their controls. It will also examine any documentation that helps to understand the system, or indicates the extent to which the system has been maintained. The energy assessor is also required to estimate whether the system is suitably sized for the cooling loads in the treated spaces and to provide advice on ways in which the performance of the system might be improved.
What can I expect in the report?
The purpose of the inspection report is to ensure that the building owner or manager is provided with information regarding the efficiency of the air conditioning systems that they control, together with advice on how to improve the energy efficiency of the system, to identify opportunities to save energy and to reduce operating costs.
The air conditioning inspection report will include at least the following details:
The likely efficiency of the system and any suggestions made for improvement
Any faults identified during the inspection and suggested actions
The adequacy of equipment maintenance and any suggestions for improvement
The adequacy of the installed controls and control settings and any suggestions made for improvement.
The current size of the installed system in relation to the cooling load any suggestions for improvement.
Summary of the findings and the key recommendations
There is no legal requirement to act on the recommendations. Acting on the advice and key recommendations in the inspection report and rectifying faults or making appropriate improvements, where this is attractive and cost effective, will contribute to the efficient running of air conditioning system, which will contribute to a reduction in carbon emissions and reduce the operating costs for the building occupants.
