Why Are These Required?

The EU Legislation under the direction of the Energy Performance of Buildings Directive (EPBD) states that the aim of this TM44 inspection is as follows:
The primary aim of the inspection is to give building owners and operators information about the performance of their buildings and plant, and to identify opportunities to save energy and cut operating costs.


Premises To Let or For Sale

Current EPBD Legislation requires that all properties being sold or to be let must be complete with a current Energy Performance Certificate and a TM44 Air Conditioning Report.

These two documents will always be requested by the Solicitors dealing with the Transaction and form part of the Legal documentation to complete the transaction.


Systems Requiring An Air Conditioning Inspection

All installed air conditioning installations greater than 12 Kw of cooling that are used for comfort of the employees will require an inspection.

This equates normally to 2 off split system AC units being installed.

Only one TM44 air conditioning inspection is required on a single building where there are numerous AC units installed.


How Long Does a TM44 Site Survey Take?

Typically, 1 to 2 days on-site with a further day to complete the report.


What Does An Air Conditioning Inspection Cover?

The primary aim of the inspection is to identify opportunities to save energy and cut operating costs. If the recommendations of the report are implemented, the savings will improve the accounts’ bottom line figures.

1. Components of the Air Conditioning inspection being:
2. Age and Condition of the equipment.
3. General standard of maintenance and the cleanliness of the installation.
4. Controls and their set up – to determine if excess energy is being used.
5. Temperature settings and occupants’ comfort.
6. Air handling units and indoor fan coil units – condition and operation plus type of motor and drive systems.
7. Filter cleanliness and number of visits per annum
8. Duct cleanliness and air leakage
9. Cooling Towers (where installed)
10. HSE Legislation and F Gas register compliance.
11. Refrigerant Gas and Quantities and leak testing.
12. R22 equipment and its use which has been banned since January 2015.
13. Energy monitoring and energy use of the installation.
14. Electricity sub meters measuring the AC equipment usage.

On completion of the site survey and the issue of an Air conditioning report known as the CIBSE:TM44 inspection report, a list of recommendations is issued all with a view to reducing energy consumption of the total installation.

These recommendations are often quick-fix solutions with minimal costs to that of a complete update of the installation to ensure that the Energy ratings as associated with the MEES Regulations for building is complied with, especially useful where the existing installation is 12 to 15 years old.


How Often Is An AC Inspection Required?

Inspections are required whenever there is a material change in the AC installation and every 5 years on a rolling program.
