TM44 Air Conditioning Inspection

What is TM44?

TM44 is a technical memorandum from the Chartered Institution of Building Services Engineers that provides guidelines for inspecting air conditioning systems in the UK, Republic of Ireland, Malta, and Gibraltar. It supports compliance with the Energy Performance of Buildings Directive, requiring regular inspections of air conditioning systems with a cooling capacity exceeding 12kW every five years.

The inspections, conducted by accredited energy assessors, evaluate system efficiency, controls, maintenance, and sizing to identify energy-saving opportunities, reduce carbon emissions, and ensure compliance.

The resulting report offers recommendations for improving efficiency and performance, helping building owners and managers meet legal obligations and optimize operational costs.
