Measurement data on domestic hot water consumption and related energy use in hotels, nursing homes and apartment buildings in Norway

The data article describes detailed measurements of domes- tic hot water (DHW) consumption in 12 Norwegian buildings. Included in this study are 4 hotels, 4 nursing homes, and 4 apartment buildings in the greater Oslo region. Flow and temperature measurements were performed on the DHW production system in each building’s heating plant, for a du- ration of at least 6 weeks. The measurements were con- ducted with an interval of 1 s, and then averaged for 2 s before analysis in order to reduce data noise and measure- ment uncertainties. The data set includes flow rates, tem- peratures, energy for consumed hot water (CHW) and dis- tribution losses in the hot water circulation (HWC). Reuse potentials consist of analyses related to flow rates, energy use and distribution losses, e.g. in peak flow rates analysis or DHW energy flexibility simulations. The measurements were performed within the research project “Energy for domestic hot water in the Norwegian low emission Society”(Varmt- Vann2030)
