The IEE HARMONAC project has a number of aims:

• To understand more clearly how air conditioning systems consume energy. This was achieved through measurements and investigations of Case Studies of working airconditioning (AC) systems from across Europe – a vital first step for assessing the real energy saving opportunities available from such systems

• To assess the opportunities for energy savings that the current standards for inspection of AC systems would identify in practice, and compare these to the Case Study Energy Conservation Opportunities (ECOs) found.

• As a result of the project, to propose a series of AC inspection procedures.

• To provide new field-tested materials and tools to aid inspectors in the inspection process.

• To ensure the information is presented to the main actors in the field concerned with regulating this area. This will help produce regulation and legislation in this area that maximises the energy and cost benefits to the system owners, and hence to Europe, from the time and money invested in these inspections.
