Individual Household Behaviour Modelling as a Precursor for Energy Use Modelling

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Household behaviour plays a key role in the energy demand of residential buildings, and
its importance will increase when moving towards nearly zero energy buildings.
However, little information is available on how users interact with their homes. In building
performance simulations, user behaviour is often included through simplified and
undifferentiated user profiles. More detailed information on building occupancy and use
of appliances is required.

In this paper, a model is presented that generates individual household profiles for
residential buildings. The calculation algorithm is calibrated with an extensive Belgian
time-use and household budget dataset describing the activities and whereabouts of
household members. The first aim is to present a three state occupancy model that
produces occupancy patterns for individual household members. The second is to
present an activity model that generates household activity patterns for nine energyconsuming activities with a time resolution of 10 minutes. The central variables of the
model are occupancy, the probability to start a certain occupancy state and the activity
duration probability.

In order to provide more realistic user profiles for subgroups of the population, we have
defined and analyzed different household types. Since household energy consumption
depends largely on the presence of household members in the building, household types
are defined based on the household structure and the employment type of the adult(s).
These user profiles can be implemented in both stationary energy performance
modelling and dynamic energy balance simulations.
