Air conditioning inspections are a legal requirement:

How to ensure you comply

If your building has air conditioning, you have a legal obligation to have it inspected to ensure it performs efficiently.

This mandatory requirement is contained in the revised Energy Performance of Buildings Directive (EPBD), which came into force progressively from January 2013 and is now operational across England, Wales, Scotland and Northern Ireland.

What it covers

It requires all air conditioning systems with a cooling capacity of more than 12kW to be inspected, in order to assess their efficiency.

Inspections must be carried out to TM44, a detailed guidance note produced by the Chartered Institute of Building Services. This sets out the qualifications required by authorised inspectors, the principles of approach for inspections and the detailed process for assessing the efficiency of air conditioning systems under the EPBD. It also requires inspectors to make recommendations for improving the efficiency of plant.

How it works

Information gathered from inspections must be presented in the form of official reporting templates, produced by the Department for Communities and Local Government. These are submitted as formal evidence of compliance with the law.

The type of systems

The focus is on systems that use refrigerants to produce cooling. However, some of the guidance in TM44 may also be applicable to other forms of cooling systems, such as those which use pipes or ducts built into the fabric of the building (e.g. cooled deck or ceiling slabs), or those which use aquifers or local water sources to provide cooling solutions.

What does an inspection involve?

Inspections include an evaluation of the cooling requirements of the building, the capacity of the air conditioning system, its suitability and operational efficiency. Other elements include:

Review of available documentation

Evaluation of maintenance standards, with reference to good practice

Inspection of main system components

Evaluation of controls and system set-up

Recommendations for improvements

Overview of key findings and advice

When must inspections be done?

All air conditioning systems over 12kW installed from the start of 2008 must be inspected within five years of installation, and then every five years from the date of the first inspection. Therefore, the deadline has already passed for relevant systems installed earlier than five years ago.

The benefits

An inspection ensures compliance with the law

It can deliver reductions in energy use, carbon emissions and running costs

Improved equipment performance, leading to better conditions within the building and happier occupants

How Aermec Service can help you meet your legal obligations

Our fully trained field engineers carry out TM44 inspections for some of the largest companies in the UK. They are equally experienced in medium size and small air conditioning applications.

An experienced Aermec engineer is assigned to carry out the inspection on your building or estate. Their report gives you a clear statement of how your system is operating, and provides recommendations for improving efficiency and reducing running costs. These include no-cost and low-cost options for improvements.
