TECHNICAL FEATURE
codes could be enhanced to better incorporate occupant
behavior, ranging from simply updating schedules and
densities to mandating more advanced occupant modeling
methods. With these recommendations adopted,
buildings will have a higher chance of achieving energy
and comfort performance targets. Future work should
extend beyond occupants to consider how operator
behavior affects energy performance and the gap
between design and measured performance.
Interested readers are encouraged to refer to O'Brien,
Tahmasebi et al.,10 which provides much greater detail.
