TM44 Inspection Yorkshire – Air Conditioning Energy Assessments
NRG Focus provides professional TM44 air conditioning inspections for commercial buildings throughout Yorkshire and across the UK.
If the combined effective rated output of the air conditioning system within a building is more than 12kW, regular energy inspections are required.
These inspections must be undertaken by an accredited air conditioning energy assessor at intervals not exceeding five years.
NRG Focus works with building owners, facilities managers, landlords, businesses and organisations requiring TM44 inspections for individual commercial properties and larger multi-site estates.
Whether you need to establish if an inspection is required, replace an expired report or arrange assessments across several properties, our team can help.
What Is a TM44 Inspection?
A TM44 inspection is an energy assessment of the air conditioning systems within a building.
The inspection considers the efficiency and operation of the air conditioning equipment and its controls, helping the person responsible for the system understand its current performance and identify opportunities for improvement.
The term “TM44” comes from the Chartered Institution of Building Services Engineers (CIBSE) TM44 guidance used for the inspection of air conditioning systems.
Following the inspection, an Air Conditioning Inspection Report is produced detailing the findings and recommendations.
Does My Building Need a TM44 Inspection?
Air conditioning systems with an effective rated output of more than 12kW require inspection.
This threshold can be reached by one large system or by several individual systems within the same building that collectively form the air conditioning provision.
This means the requirement isn’t limited to large office blocks or buildings with major centralised cooling plant.
Commercial premises containing several smaller air conditioning units may also fall within the requirements.
If you are uncertain whether the air conditioning equipment within your property exceeds the relevant threshold, NRG Focus can help you establish whether an inspection is required.
How Often Is a TM44 Inspection Required?
Where an air conditioning inspection is required, it must be carried out at regular intervals not exceeding five years.
Businesses and property managers should therefore retain their previous inspection documentation and monitor the date on which another assessment will be required.
If responsibility for an air conditioning system changes and the new person responsible is not provided with an existing inspection report, there are specific requirements concerning arranging an inspection.
NRG Focus can review the information available and help establish what is required.
Who Is Responsible for Arranging the Inspection?
The legal responsibility rests with the person who has control of the operation of the air conditioning system.
Depending upon the building and contractual arrangements, this could be a:
Landlord
Tenant
Building owner
Facilities management organisation
Property management company
Business occupying the premises
For multi-let commercial buildings, responsibility will depend upon who controls the relevant air conditioning systems.
Where responsibility is unclear, the lease and arrangements for operating and maintaining the equipment may need to be considered.
What Happens During a TM44 Air Conditioning Inspection?
The assessment examines the air conditioning equipment and associated controls to consider how effectively and efficiently the system is operating.
The inspection may include consideration of:
Air conditioning equipment
System controls
Operating settings
Maintenance information
Cooling requirements
System sizing
Condition of accessible equipment
Opportunities to improve energy efficiency
Potential improvements to system operation and control
The purpose isn’t simply to produce another compliance document.
A properly conducted inspection can identify practical opportunities to reduce unnecessary energy consumption and improve the way the air conditioning system is operated.
What Do I Receive After the Inspection?
Following the assessment, an Air Conditioning Inspection Report is produced.
The report provides information about the system and recommendations that may help improve its energy performance.
Recommendations can include measures concerning:
System operation
Controls and control settings
Maintenance
Equipment efficiency
System management
Potential improvements or replacement
Reducing unnecessary air conditioning use
The recommendations themselves are advisory rather than a requirement to carry out every suggested improvement.
However, they can provide useful information for facilities managers and building owners planning future maintenance or energy-efficiency improvements.
TM44 Inspections and Reducing Energy Costs
Air conditioning can represent a significant part of the energy consumption of a commercial building.
Poor controls, inappropriate operating periods, inefficient equipment or unnecessary cooling can increase running costs considerably.
One of the benefits of a TM44 assessment is that it provides an independent examination of the system from an energy-efficiency perspective.
In some buildings, relatively straightforward operational or control changes can provide opportunities to reduce energy consumption without major capital expenditure.
For organisations managing larger estates, identifying these opportunities across several buildings can be particularly valuable.
TM44 Inspections for Commercial Buildings
NRG Focus can provide TM44 air conditioning inspections for a wide range of commercial and public buildings, including:
Office buildings
Retail premises
Business centres
Industrial properties
Warehouses with conditioned areas
Healthcare premises
Schools and education buildings
Public buildings
Hotels and leisure facilities
Multi-let commercial buildings
Large corporate premises
Buildings with complex HVAC systems
The scope of an assessment depends upon the size, configuration and complexity of the air conditioning systems installed.
TM44 Inspections for Multiple Air Conditioning Systems
A common misunderstanding is that the 12kW threshold relates only to an individual air conditioning unit.
Commercial buildings frequently contain numerous smaller systems serving different rooms, floors or areas.
The relevant effective rated output therefore needs to be considered across the air conditioning system serving the building.
This can be particularly relevant in offices, retail premises, healthcare buildings and other properties where numerous split or multi-split systems have been installed over time.
If you have several air conditioning units and are unsure whether your building requires an inspection, NRG Focus can help review the system information.
TM44 Inspections for Multi-Site Organisations
NRG Focus can also support organisations responsible for multiple commercial properties.
This may include:
Property management companies
Facilities management organisations
Commercial landlords
Retail portfolios
Healthcare organisations
Education estates
Corporate property portfolios
Public sector organisations
Where several buildings require inspection, assessments can be coordinated to help clients manage access, documentation and renewal dates efficiently.
This can also provide a clearer overview of air conditioning compliance across an estate rather than treating each property in isolation.
What Information Is Useful Before a TM44 Inspection?
Providing information about the air conditioning systems before the assessor attends can help establish the scope of the assessment.
Useful information can include:
Previous air conditioning inspection reports
Equipment schedules
Air conditioning maintenance records
Details of installed systems
Rated cooling outputs
Building plans where available
Information about system controls
Details of recent replacement or alteration works
Don’t worry if all of this information isn’t immediately available.
NRG Focus can discuss what you have and explain what will be useful for the assessment.
What Happens If I Don’t Have a Valid Air Conditioning Inspection Report?
Where a qualifying air conditioning system has not been inspected in accordance with the regulations, enforcement action can be taken.
The current fixed penalty for failing to obtain a required air conditioning inspection report is £300.
There can also be an additional penalty where a valid inspection report is not produced when requested by an enforcement authority.
For many organisations, however, compliance isn’t only about avoiding a financial penalty.
Property transactions, corporate compliance procedures, facilities management systems and environmental policies can all make maintaining appropriate inspection records important.
Is a TM44 Inspection the Same as Air Conditioning Maintenance?
No.
Routine servicing and maintenance and a TM44 energy inspection serve different purposes.
Maintenance is concerned with keeping equipment operating correctly and safely.
A TM44 inspection considers the energy performance of the air conditioning system and provides recommendations concerning its efficiency and operation.
Having a maintenance contract therefore does not automatically mean that the legal air conditioning energy inspection requirement has been satisfied.
