Abstract

Building on previous papers presented on this topic at IEECB 2004 and IEECB 2002, this paper presents further findings from an energy monitoring study of the energy and carbon performance on air conditioning systems in 32 UK office buildings over a period of three years with the aim to aid the development of improved guidance on the appropriate use of air conditioning systems, and to help identify strategies to achieve national carbon emissions reduction targets. This paper focuses on the building energy use and carbon emissions from 27 buildings in which the air conditioning systems have been monitored derived from energy billing data and monitoring and targeting (M&T) data. The results presented include analysis of the overall energy consumption and associated carbon emissions of each building studied, comparisons to the relevant UK national benchmarks, breakdown of energy use by fuel type and identification of the proportion of energy used and carbon emissions attributable to cooling purposes. The results indicate that current UK national Office energy consumption benchmarks are probably set at the correct level, and also show that the higher overall energy consumption of air conditioned buildings is NOT inherently due to the use of AC systems, but is as much to do with other building end-use. The buildings monitored with low HVAC energy consumption did not necessarily lead to energy savings at the building level.
