Air Conditioning Energy Assessment

Air Conditioning Reports (ACRs) revolve around a number of set criteria which will vary depending on the type and complexity of the installed system.

Air conditioning systems, as described by Communities and Local Government (CLG), typically consist of refrigeration equipment, air movement systems and controls. Under new guidelines, the existence of these systems must be recorded and all relevant documentation such as manuals, drawings, maintenance records, commissioning data and control strategies should be inspected.

A review of the system will assess if it is suitably sized for the cooling loads in the treated spaces and the overall effectiveness of the system. The report will conclude with observations and recommendations on energy-saving opportunities.

  • First inspection of all existing systems over 250kW cooling capacity must be completed by 4th January 2009
  • First inspection of all existing systems over 12 kW must be completed by 4th January 2011
  • New systems over 12kW installed after January 2008 must be inspected within 5 years of being put into service
  • Each ACR is valid for a maximum of 5 years

We carry out an extensive survey of the air-conditioning system(s) onsite and produce an advisory report which is both issued to the building owners and lodged on the Non-Domestic Energy Performance Certificate Register. Advisory reports contain:

  • Detailed inspection notes and an assessment of the overall performance of the air-conditioning system
  • Calculations to assess whether the system is adequately sized or oversized for purpose
  • Recommendations for building owners which, if implemented, improve the efficiency and reduce the energy consumption (and CO2 emissions) of the system, resulting in reduced operating costs
  • Alternative solutions to strategy, maintenance regimes and air-conditioning technologies
