Abstract

The AuditAC project is producing information which will enable the energy efficiency of Air Conditioning Systems to be improved through Audits and Inspections. Part of the basic information the project will produce is guidance on the type of loads imposed on the AC systems by the building and occupancy characteristics. The driver for this is Article Nine of the European Directive on the Energy Performance of Buildings which requires “regular inspection” of all systems above 12kW rated output. Part of the inspection is also to determine if the required cooling loads can be reduced or met by alternative solutions such as solar shading devices and more effective glazing systems. Following on from 2 previous papers presented on the energy use of Air Conditioning systems at IEECB 2004 , , this paper presents an initial overview of the relative importance, amplitude and time-varying nature of the components of the heating and cooling load found in a UK Office. These components have been obtained using the modelling methodology outlined in another IEECB ’06 conference paper and are semi-empirical in nature. The load components presented are the ‘internal gains’, ‘ventilation and infiltration’, ‘fabric’ and solar components, and have been derived from the modelling of one Office from the original Welsh School of Architecture “AC Energy Use in Offices: Field Monitoring Study”. Information of this nature will be invaluable in assessing which actions might initially be the most effective in reducing the energy consumption of heating and cooling systems in UK Offices by measures such as solar shading and glazing treatments, as it shows how much of the total heating and cooling load we might expect to meet through such actions. The paper then goes on to examine the nature of the Solar Component in UK Offices. The methodology used in the two analyses will be used to inform the AuditAC study and, as a result, the guidance to be provided for countries other than the UK
