Inspection and auditing of air-conditioning facilities in Europe – A new efficiency target

Share this Post:
The paper details the EPBD article 9 on the inspection of air conditioning systems and explains its scope, objectives and stakes. Indeed, too costly or too frequent inspections could create market distortions by leading building owners to prefer low capacity equipments that can be less energy-efficient. The paper focuses on the definition and the relevance of the 12-kilowatt limit and then on the type of installations included in the scope of that inspection. Then inspection and audit markets in the European Union, especially in the five biggest markets, are modelized. The model shows that the air-conditioning market will increase a lot in the future and that present stock will become obsolete very soon. Inspection and audit markets are therefore enormous. Standardisation is one way to accelerate the adoption process for this regulation. The draft CEN standard is presented and discussed.
