Public or commercial building? You need an air conditioning inspection. Air Conditioning (AC) Inspections are a legal requirement under the Energy Performance of Buildings Regulations (EPBR).

Air Conditioning (TM44) Inspections

TM44 – AC Inspections

Air Conditioning (AC) Inspections are a legal requirement under the Energy Performance of Buildings Regulations (EPBR). The aim is to improve the energy efficiency of public and commercial buildings, and ultimately reduce carbon emissions.

The inspections were introduced in 2009 and an accompanying Air Conditioning Inspection report will highlight areas where operational improvements can be made to air conditioning systems. Often the savings identified will cover the cost of the inspection.

All air conditioning systems with a combined cooling capacity greater than 12kW are required to have a valid Air Conditioning Inspection report and a certificate in place, with financial penalties present for non-compliance. Inspections for systems above 250kW have been compulsory since January 2009 and systems 12kW – 250kW since January 2011.

An inspection can only be undertaken by an accredited Energy Assessor and must be carried out at least once every five years.

Air Conditioning Inspections are often referred to as ‘TM44 Air Conditioning Inspections’ or a ‘TM44 Inspection’. CIBSE TM44 is in fact the guidance used for all Air Conditioning (AC) Inspections conducted in the UK.
