“…Although the office buildings that have achieved the lowest reported lighting electricity consumption have done so with manual electricity management [15,16], some studies show that under manual switching lighting management it was quite common for users to switch on lights even when there was adequate glarefree daylight [17]; once switched on, the lights were seldom switched off, regardless of the illumination provided by the daylight [16]. Thus there is an argument for an automated electricity management strategy which maintains efficient electricity consumption to satisfactorily meet electricity users' electricity needs and meanwhile minimizes the cost of electricity without any user intervention in office buildings.…”

a b s t r a c tIn this paper, we develop an agent-based model which integrates four important elements, i.e. organisational energy management policies/regulations, energy management technologies, electric appliances and equipment, and human behaviour, to simulate the electricity consumption in office buildings. Based on a case study, we use this model to test the effectiveness of different electricity management strategies, and solve practical office electricity consumption problems. This paper theoretically contributes to an integration of the four elements involved in the complex organisational issue of office electricity consumption, and practically contributes to an application of an agent-based approach for office building electricity consumption study.

Modern UK office buildings have a reputation of being energy profligate, largely due to the fan power require ments of commercial air conditioning. Most architects and HVAC designers only associate low-energy con sumption with natural ventilation. However, the UK elec tricity utilities have peak maximum demands in winter, and buildings need to be designed for year-round low- energy usage. Relatively few monitored studies of the total annual energy implications of natural and mechani cal ventilation strategies operating in conjunction with fabric thermal storage have been published. This paper reviews independently published performance data of low-energy buildings and the impact of the various venti lation and fabric energy storage strategies now avail able. It demonstrates that low-energy mechanical venti lation systems incorporating efficient heat recovery and effective fabric energy storage have higher year-round comfort criteria, and significantly lower prime energy consumption, than natural ventilation strategies. Sup plementary cooling and heating demands and consump tion are shown to be minimal in such buildings for tem perate maritime climates.

“…Designed in 1978, it was the first mixed-mode design to incorporate fabric energy storage using natural ventilation to cool the exposed ceiling soffit overnight. It was also the first green building to publish its annual energy consumption figures for 1981-1986 (tables 1, 2) [2].…”
