Occupant adaptive behaviour: an effective method towards energy efficient buildings
2018
Energy efficient buildings play an important role in achieving a sustainable society.
Conventional methods achieving energy efficient buildings mainly focus on upgrading
the physical properties of the building, such as increasing their thermal insulations,
neglecting the occupants who are using the building. This study justifies the potential
contribution of a new method, i.e. selecting offices for occupants with a consideration
of their behavioural preferences and the building’s physical properties, to the
building’s energy efficiency. Dynamic building performance simulation has been
adopted for the justification, based on a case study building with a simple rectangular
shape. The occupant window behavioural model was developed from field measured
data in an office building and the up-to-date stochastic approach was used to predict
the state of windows for the simulation. Simulation results clearly reflect that 1)
building’s physical properties, such as window orientation, have impact on the
thermal performance of the building; 2) occupant behaviour can also affect the
thermal performance of the building; and 3) considering both occupant behavioural
preference and building’s physical properties can promote building’s thermal
performance, without requirement of changing occupant behaviour.
