ABBE Air Conditioning Energy Assessing

The Energy Performance of Buildings Directive introduces a requirement for building air conditioning systems to be inspected for energy efficiency. This requirement came into effect for large systems in January 2009 and will apply to most systems from January 2011. Only air conditioning assessors will be able to carry out these inspections.

Case Study 1

Follow the engineer as he undertakes an inspection at a cafe. He will identify some common faults, and will explain how real savings can be made by a better choice of lighting, and suggesting improvements to the condensing units.

Case Study 2

This inspection took place at an empty office building. The engineer discusses best practice and common faults. During the course of the inspection the engineer identified systems with R22 refrigerants, poor location of condensers and lack of essential documents.

Case Study 3

This inspection took place at a design studio. The engineer demonstrates how to work with the owner of the building. He also identified problems associated with the location of condensers, and issues with the control setup. Despite being a recent building conversion this the engineer was able to provide several recommendations for this building.

Case study 4

This inspection took place at a purpose built unit used as a motorbike showroom. The engineer explores damage to condensing units; build up of dirt on the filters of an indoor unit, and obstructions of the air path leading to poor performance of the condensing units.
