A TM44 survey is an in depth survey of the air conditioning unit(s) on site, followed by a desk based exercise where the data is processed into a detailed document of the findings and ways that the unit(s) can be optimised.

The TM44 certificate, or report, is a detailed document that is compiled after a site visit, it includes information such as:

  • Key Findings - building performance, average system energy rating, etc.
  • Executive summary - purpose of the survey, building information, business hours, maintenance, etc.
  • Tables and Calculations - assets register, equipment, comparisons, energy usage, ACE WIZARD energy calculations, etc.
  • Site photographs.
  • Ways to improve the unit in terms of carbon emissions, energy bills, etc.
