Where an individual building benefits from the refrigeration plant of an air conditioning system under single control, the building owner or manager is responsible for obtaining an air conditioning inspection report if the rating of the local cooling plant in the building is greater than 12kW.
The buildings are not covered by the air conditioning plant under single control, unless the systems in these buildings are a permanent part of the air conditioning system.
The example below shows an air conditioning system with a cooling capacity greater than 250kW that serves four separate buildings. Although the air conditioning system serves four separate buildings the air conditioning system is a single system under single control with a cooling capacity greater than 250kW. An air conditioning inspection on a system with a cooling capacity greater than 250kW should have been carried out by 4 January 2009. A revised air conditioning inspection report would be required every 5 years from the date of the initial inspection.
Air conditioning systems in buildings 1-4 are part of a district cooling system and are controlled by the same person.
Together the total capacity controlled is > 250kW.
The first inspection must have been completed by 4 January 2009.
