If the documentation is not available, then an additional part of this procedure is to locate the equipment and assemble a minimum portfolio of relevant documentation.

Comments on the frequency and scope of maintenance of the air conditioning systems shall be covered in relation to national requirements and good practice, e.g. industry guidelines, This, and the dates of most recent maintenance may be referred to during the ‘physical’ inspection. Where there is clear evidence that a good practice program of maintenance is being carried out, then the inspection described in this standard may be simplified or reduced in accordance with the classification.
When checking the performance of different parts of an air-conditioning system, the measurement methods employed will assist subsequent follow-ups. To make this possible, the instructions for each measurement method shall be followed and the instruments for the measurements calibrated in accordance with the manufacturer's instructions.
Compare system sizes with likely loads. Annex F contains procedures for assessing whether refrigeration systems and air supply and extract systems are likely to be oversized. Estimate the Specific Fan Power of the air movement systems whenever relevant, from the installed fan capacities and the flow rates, noted in the commissioning records.
4.2 Pre-inspection and document collection 4.2.1 Documents 4.2.1.1 General
Prior to inspection, where possible, the design criteria, system characteristics and the operational regime shall be determined. All available original documentation relating to the building and the installed systems shall be collected and assessed. Additional documentation, if it exists, indicating any modifications or alterations to the building, the systems or the use since the original documents, shall also be obtained and assessed. Annex D provides examples of documents needed. 4.2.1.2 Design documentation Collect and identify available current relevant documents to support the inspection and the relevant subsystems and components.

The energy certificate, if available, shall be used. Correspondence between documentation and actual installed components shall be checked. Any difference shall be stated in the report.
The design documents, where available, which define the relevant design criteria, shall be checked against the actual installation and the present use. 4.2.1.3 System characteristics Working or as installed drawings shall be checked against the actual installation and use of the building.
An equipment list shall be obtained or prepared. If available, the commissioning data shall be checked against the present system. 4.2.1.4 Building and system operation and maintenance status Determine whether the air conditioning system, subsystems or components are regularly and correctly operated, and maintained by qualified and/or authorised personnel according to: • System designer’s instructions • Manufacturer’s instructions of the subsystems and components • Any legal or statutory requirements The maintenance status is an important part of the inspection. Check the maintenance records for the system and for individual items of the system, as well as the building and system log book.
4.2.2 Building and system survey Advise the user to keep and maintain any documentation determined above and any survey or calculations carried out during the initial (first) pre-inspection in a file so that they are available for subsequent inspections of the building and system(s).
4.2.3 Advice in case of outdated, incomplete or missing documentation In existing buildings the design and system documentation may be incomplete or even missing. The existing documentation may be partly outdated, due to undocumented changes in the use, loads, construction elements or building services systems during the building's lifetime.
In these cases, the lacking or outdated documentation shall be identified (the checklists given in Annexes F and G may be used whenever relevant), and the organisation or person responsible for the inspection shall provide the user advice on how to develop a plan to complete the documentation.
4.3 Methodology 4.3.1 General The inspection shall determine if the equipment operates in an appropriate environment and with acceptable efficiency and if maintenance and control checking operations are regularly carried out.
NOTE 1 Some of the checks and tests described here are obligatory in some countries, and may be done separately or in connection with the full inspection, and also more frequently than the full inspection if required. The inspection should take these into account as a part of the inspection if relevant.

Check the refrigeration equipment.
NOTE The checks would typically include the following items:
-refrigeration plant and its immediate surroundings; -compressors; -measurement records; -capability of providing cooling: operating temperatures, refrigerant charge, refrigerant leak; -insulation of refrigerant lines; -vibration and noise level; -condensing pressure; -efficiency data of the chillers. If any regulation requires periodic leak detection and repair, the documentation of the leak test shall be examined.
4.3.3 Inspection of pumps and chilled water pipe work Check the condition and operation of chilled water pipe work and its insulation. A good insulation, especially on chilled water systems where lengths of chilled water lines can be considerable, can have a significant influence on the system energy efficiency of the system. Check for signs of leakage from the pipe work. Check the pumps and valves for the distribution of water as an energy carrier.
4.3.4 Inspection of effectiveness of outdoor heat rejection
Locate and check the condition and operation of the outdoor heat rejection units.
4.3.5 Inspection of the effectiveness of heat exchange to the refrigeration system (indoor units of split and distributed systems) Check the condition and operation of heat exchangers inside those units installed within the treated spaces. 4.3.6 Inspection of air delivery systems in treated spaces NOTE 4.3.6 to 4.3.8 is applied in cases where the air-conditioning system includes distribution of cooling energy using ventilation. See also EN 15239. In the treated indoor spaces, locate and check the air delivery openings, grilles or diffusers, and locate the route by which air is extracted from the spaces. Note if there is any evidence that occupants find the air delivery arrangement unacceptable. Assess the positioning and geometry of air supply openings in relation to extract openings, and the potential to short-circuit from supply to extract.

Determine and record the frequency of filter changing or cleaning, and the time elapsed since the last change or cleaning. Assess the current state of cleanliness, damage or blockage of filters. Assess the condition of heat exchangers.
4.3.8 Inspection of air inlets to the system
Locate and check the air inlets to the system. 4.3.9 Inspection of the building system controls and control parameters Identify and provide advice of all controls, sensors and indicators which are relevant for energy performance, as appropriate, on: • location
• function • settings Locate and inspect the controls responsible for the operation of the air conditioning or comfort cooling system, the heating system controls, and their associated temperature sensors. Review documentation or other sources of information to determine the individual control zones for heating and cooling. Determine the appropriateness of zoning in relation to factors such as local levels of internal gain, orientation and exposure to solar radiation.
Determine, where applicable, the method used to set, modulate or control air flow rate in the air supply, recirculation and exhaust ducts. Provide a view of the efficiency compared to good current practice.
4.3.10 Metering
Meters may have been installed to air conditioning systems, such as energy consumption or running time meters. Regularly noting the readings of such meters can help assess the operation of the air conditioning system.
Where energy consumption has been recorded on a regular basis, an estimate shall be done from the rated input power and the consumption record, whether the equipment is running in accordance with the use of the building. If not, the inspection shall include advice to the owner to reduce the energy consumption.
Where meters are installed, but no consumption records are available, the inspection shall include advice to record meter readings on a regular basis. Where no such metering is in place, a part of the advice provided would be to install appropriate energy consumption metering at least to the more significant energy consuming air conditioning plant, and subsequently to record the consumption on a regular basis.

A report of the air conditioning inspection shall be prepared. The inspection report shall include at least the identification data of the property inspected and person and organisation in charge of the inspection, list of the relevant documents, and results of the inspection. One example of the list of the inspection report is given in Annex G.
The inspection report shall give an assessment of the total energy efficiency of the systems inspected.
5 Advice on alternative solutions and improvements
According to Article 9 of the EPBD, advice is to be provided to the users on “possible improvement or replacement of the air-conditioning system and on alternative solutions”. As the pre-inspected and collected information, as well the inspection results are different according to the system, the advice vary regarding the improvements and alternative solutions. The advice shall consider the main impacts for improvements: • Adaptation to the actual use of the building • Reduction of the cooling load • Improvement of the maintenance • Incorrect function of the system, the subsystems and components • Replacement of the system, subsystems or components NOTE 1 Alternative solutions may be necessary for such air conditioning systems which are far away from agreed reference values, like replacement of the whole system. Detailed cost effectiveness studies are outside the scope of this assessment, but a number of opportunities may be considered worthwhile recommending for further study by specialists. These should generally include alterations that could be made at relatively low cost, particularly those that might be considered when older equipment is due for replacement. This will allow the loading on cooling equipment to be reduced or would increase the opportunity to make use of available solutions alternative to mechanical cooling, for at least part of the time.
NOTE 2 Annex H describes in more detail some of these issues. The checklists presented in Annex F give also guidance on advice and recommendations.

Examples of inspection classes of air conditioning systems
The inspection class can be determined according to different criteria, such as:
- type of air conditioning system (generation and emission), - cooling capacity,
- annual running time,
- age of the installation, - use of the building (e.g. residential, office…) - location of the system (e.g. outdoor/indoor) and the building
-etc. The following table gives an example how to classify the system inspection class.
Table B.1 - Example of a classification system, with three inspection classes
Inspection class Specification Details Dim. Remarks 1 Nominal cooling capacity:
Annual running time:
Date of installation:

Features affecting the frequency and duration of inspection
The minimum contents and frequency of mandatory inspection is defined on national level, with a recommended default value of 5 years. On voluntary basis, more extensive and more frequent inspections are possible.
The inspection may be more or less frequent, depending on: type of building, energy impact of the system, type of equipment, quality of system documentation, availability of records of measurements and/or energy consumption metering, and quality of maintenance. For centralised systems for cooling and ventilation, different parts and system components may require more frequent checks, and in this case these records should be available for inspection.
After the initial inspection, the time for the next inspection may be longer or shorter depending on the results from the initial inspection and on the level of maintenance.
The inspection intervals recommended should be given on national level as tabled values and compared to the default frequency given above.
The outcome of the inspection will be to generate advice for the owner or manager to improve the system, or improve system maintenance. A part of that advice will be to recommend more frequent routine inspection and maintenance, for a good practice maintenance programme. The advice shall be integrated and balanced with other energy conservation recommendations. The time taken for the inspection obviously depends on the size and age of the system, type of building, time since latest inspection, quality of documentation and maintenance of the systems installed. In many cases the required extent of the inspection can be estimated from the quality of system documentation (including balancing and maintenance records), checking of self-inspection records and a relatively short visual check. In the best cases these, if they clearly give an impression of properly maintained systems and meeting the requirements of Article 9, the scope of inspection may be reduced. The checklist given in Annex F is suitable for a relatively "simple" inspection for a combined system. However, this inspection will not provide a complete picture of the system energy performance including the performance of controls.
