The generation of domestic hot water load profiles in Swiss residential buildings through statistical predictions

Measurements show that DHW consumption is very volatile. The daily average value varies from 20 to 40 l per person (60 °C outlet temperature). The profiles underlie some trends (predominantly consumption in the morning or in the evening or spread over the day). The DHW consumption in Switzerland follows similar patterns observed in other countries, such as no significant decrease in consumption during weekends, and no strong correlation with weather conditions neither outdoor temperature nor rain.
