Domestic hot water usage measurement with one minute resolution for 648 apartments in Swedish multi-family buildings

https://doi.org/10.58062/zg8w-gp13
A time-series of domestic hot water usage for 648 individual apartments in eight separate multi-family buildings of different sizes and located in multiple Swedish towns. The measurements were performed in February and March of 2021. The values recorded are cumulative usage in liters with a time resolution of 1 minute. The length of the time-series is either 22 days or 25 days depending on which of the buildings in the study the apartment belongs to.

Description of the mode of collection:

The cumulative domestic hot water usage contained in this dataset was originally measured by reading the value of a single jet turbine meter at approximately 1 minute intervals (70% are <= 60s, 93% are <= 62s). The measurements were done sequentially, going around to each of the turbine meters in the same house in turn. These values originally recorded are whole liters, the re-sampling has introduced some fractional values. Measurements were performed for 22 or 25 days depending on which building the apartment is in. These time-periods overlap partially by almost 13 days, i.e. there are almost 13 days worth of samples where all apartments are measured at the same time. The raw measurement data was processed by separating the timestamped meter readings into separate streams for each apartment. The earliest timestamp, rounded to a whole minute, was used as the starting point for the resampling that was then done on every even minute until the end of the data. Resampling was done by linear interpolation to whole minutes. The length of the measurement interval in the raw data was also recorded for each sample.
