Abstract

This report describes data regarding hot water draw patterns that Lawrence Berkeley National Laboratory obtained from 10 studies. The report describes our purposes in collecting the data; the ways in which we managed, cleaned, and analyzed the data; and the results of our data analysis. We found that daily hot water use is highly variable both among residences and within the same residence. We also found that the distributions of daily hot water use are not symmetrical normal distributions. Thus we used median, not average, values to characterize typical daily hot water use. This report presents summary information that illustrates the results of our data collection and some initial analysis.
