ADDING SUB-HOURLY OCCUPANCY PREDICTION, OCCUPANCY-SENSING CONTROL AND MANUAL ENVIRONMENTAL CONTROL TO ESP-r

Denis Bourgeois, Jon Hand, Iain Macdonald, Christoph Reinhart

Abstract: A wide range of events in buildings occur at subhourly frequencies. Notable examples include daylight-sensing control and manual adjustment of blinds and lights in response to sub-hourly illuminance variations. Such short-term changes can produce notable shifts in instantaneous solar and equipment loads, in turn affecting electrical energy demand. Although sub-hourly time discretization is currently available in several whole building energy simulation programs, it remains challenging to model this level of complexity as traditional hourly utilization or diversity profiles describing occupancy, lighting and equipment loads remain the basic input data model. This paper provides a background review of various models predicting occupancy, occupancy-sensing control and manual environmental control, and outlines their current addition to whole building energy simulation, in particular ESP-r. This should be taken as an outlook on current work; as such, no simulation results are presented within the scope of this paper.
