CIBSE TM44 assessment – an energy efficiency assessment of a buildings air conditioning system with a rated output of 12kW or more. BSSEC provides air conditioning inspections to CIBSE TM Air conditioning inspections are required under the Energy Performance in Buildings Directive. CIBSE TM44 is used as the guidance for air conditioning inspections in the UK, the TM44 provides guidance on conducting an air conditioning inspection to.

Low Energy Consultancy have a dedicated team of accredited air conditioning inspectors who are able to provide level 3 simple and 4 complex inspections.

The log book should reflect the lifetime of the system.

Reasons The regulations have been put in place as a means of assessing the energy performance of a building and the plant that serves it. Does your Air-Conditioning System require Refrigerant. Skip to main content. Mandatory inspections The inspection of air conditioning systems in non domestic buildings with a rated output of over 12kW became mandatory in January in England and Wales, under the Energy Performance of Buildings EPB Regulation 20 Article Air Conditioning Inspection Certificates Advice and consultancy services help meet legislative requirements on efficiency, Necessary documentation for yourto buildings installed air conditioning, maintenance and EU compliance.

The F Gas Register has to be updated after each system breakdown, service call or maintenance visit civse of whether it involves refrigerant loss or replenishment. There cannot be more than five years between each inspection, which must be carried out by an accredited energy assessor.

Heavy-Duty Truck Sytems Chapter The report also identifies whether mandatory requirements such as the F Gas Register are in place. For more information callor email us.


Development Of Quantitative Structure. The inspection is a legal requirement and is designed to improve efficiency, reduce energy consumption, operating costs and the carbon emissions of air conditioning systems. The likely efficiency of the system Any faults and suggested actions The adequacy of the equipment maintenance The adequacy of the controls and control settings The current size of the system in relation to the cooling load Summary containing key recommendations and improvements The energy assessor will suggest any improvements that could be made to your existing system to ensure it performs efficiently.

Our Inspectors This may be through improved maintenance procedures but will certainly include references to systems accessories, controls and general operation that can all be adopted to reduce power consumption and CO2 emissions.

CIBSE TM44 Inspection of Air Conditioning Systems

As the quality and frequency of system maintenance affects efficiency, the inspections represent an independent assessment of whether the maintenance being carried out is appropriate. Mechanical cooling refers to a system that contains some form of refrigerant. Documents Flashcards Grammar checker. Analysis of Thermal Cycles ME The inspection will examine the following: With the benefit of the experience gained over the past three years, and to clarify some of the questions about air conditioning system inspections that have arisen over that period, the guide has been revised.

Refrigerant Thermal Decomposition Products. This applies to multiple systems as well as single units so a site with four 4kW air conditioning units also needs to be inspected. Would you like to stay in touch with us? Refrigerants and Your Air Conditioning System. The revision has also provided the opportunity to incorporate the separate legislative requirements for Northern Ireland and Scotland in the main text of the guide, rather than as separate addenda.

These templates will also form the basis for statutory lodgement of air conditioning inspection reports, which will be required in England and Wales as from 6th April under amendments to the Energy Performance of Buildings Regulations It is primarily intended to support inspections which are carried out for compliance with the EPBD, but it is also useful to anyone who wishes to assess the energy efficiency of an air conditioning system.


These items should be signed and dated by the engineer. This should identify each system, any maintenance carried out, the nature of any repairs, any leakage checks annual for small systems, 6 months for systems containing more than 30kg of refrigerantrefrigerant losses and also any refrigerant added for each HFCF or HFC system.

Air Conditioning Inspections, CIBSE TM44 Guidance and EPBD

The issue takes into account the reporting templates produced by the Department for Communities and Local Government for the production of reports in England and Wales. A TM44 inspection report is now required when selling or letting a property, along with other energy efficiency assessments for your building.


Air conditioning is an often overused word, but in the context of the inspections encompasses all systems that either include mechanical cooling directly or are served by equipment including mechanical cooling. The energy assessor will suggest any improvements that could be made to your existing system to ensure it performs efficiently. Read details of our Privacy Policy Sign up to our Newsletter. For older systems that run on R22 refrigerants — a gas which is now banned by the EU for its harmful global warming effects — the assessor should suggest replacing the system with a modern more efficient system.
