Air Conditioning Inspectors: Commercial Buildings Air Conditioning Inspection

Air Conditioning Inspectors & Air Conditioning Energy Assessors will be required for Industrial, Commercial Property and Buildings as part of the EU EPBD Directive commencing 2008. Inspection of HVAC (Heating Ventilation Air Conditioning) systems will require to be inspected to ensure that the systems are operating efficiently. Energy Assessment of Commercial/Industrial Buildings will require inspection of Commercial Air Conditioning Units installed in new and existing property, find out more about the commercial EPC and how the regulations affect your business.

The scope of inspections for owners of commercial buildings is provided beow

For Packaged air conditioning systems

Inspect simple / packaged air conditioning systems, generally applied where cooling is provided in conditioned spaces using indoor units that contain refrigerant to air heat exchangers and an integral air circulation fan. These may be either integral with outdoor units that contain the refrigerant compressor, refrigerant to outdoor air heat exchanger or circulation fan, or connected to the outdoor unit by refrigerant pipework.

Such air conditioning systems would include:

Unitary packaged systems
Split packaged systems
Multi-split packaged systems
Variable refrigerant flow (VRF) systems

The scope of the inspection is to assess the efficiency and sizing of the system compared to the cooling requirements of the building. In turn, this will enable the production of a report, which advises the client on issues that affect energy efficiency and the use of installed air conditioning systems, and recommend improvements where required.

The criteria and method used in the assessment is CIBSE methodology.

The assessor needs to determine the design intent of the system installed, the type, features and location of the system installed, the size of the area served by the system, maintenance records relating to the system, and the energy consumption of the system

For more Complex / central air conditioning systems

Inspect complex / central air conditioning systems, applied to more extensive and more complex systems that are generally characterised by the use of water or air distribution systems to deliver cooling to conditioned spaces using a
variety of active (i.e. that contain air moving fans) or passive terminal devices. Generally such systems
include more complex controls that may break down the conditioned spaces into zones where different control parameters can be applied, and that could be located remotely from the equipment, or incorporated into a building management system (BMS). The inspection of systems would include:

Centralised cooled air systems
Centralised cooled water systems
Water loop / reversible heat pump systems
Additional systems i.e. where areas are served by packaged, split and multi-split packaged comfort cooling equipment, including variable refrigerant flow (VRF) equipment.

The inspection is to assess the efficiency and sizing of the system compared to the cooling requirements of the building. In turn, this will enable the production of a report, which advises clients on issues that affect energy efficiency and the use of installed air conditioning systems, and recommend improvements where required.

The assessor needs to determine the design intent of the system installed, the type, features and location of the system installed, the size of the area served by the system, maintenance records relating to the system, energy consumption of the system.

The criteria and method used in the assessment is CIBSE methodology.

The assessors report will contain where necessary, replacement of the system or parts of the system, rectification of faults, improvements (e.g. to maintenance plan, for system controls) and best practice.

The report will contain details of:

the property inspected and the inspector
details of the system inspected
details of the results of the inspection, including recommendations
the design intent of the system inspected versus its actual operating performance (takingaccount of any ways in which building usage has changed over time)
any additional advice relating to the installed system.
