Abstract: In building simulation, deterministic reference load profiles are normally used to represent domestic hot water (DHW) demand. Limited studies are found in the literature about the stochasticity of DHW consumption. As an attempt to fill this need, a stochastic end-user DHW demand model was constructed with temporal coherency with a well known occupancy generator. The tool uses aggregated data from national surveys to effectively scale occupant behaviour models built in different parts of the world to produce the output for a given configuration. This tuning procedure is necessary to account for variations of occupant behaviour between different countries. The model displayed great accuracy in predicting the building DHW demand when its outputs were compared with measurements made in a multiresidential building in Quebec City, Canada. At its current status, the tool can be used for US, Canadian and UK dwellings, but the idea could be expanded for other locations.
