Abstract: We investigated domestic hot water consumption in four apartment buildings (a total of 48 units) managed by the San Francisco Public Housing Authority (PHA). In each of the buildings, we monitored system performance for 4–6 months and interviewed residents about hot water usage patterns. The shape of the measured profiles of daily domestic hot water consumption is different from that of published profiles, suggesting that cost-effective retrofits in multifamily buildings should rely on hot water use profiles in these kinds of buildings rather than those in single-family dwellings. We constructed a model of household water consumption based on reported behavior and found occupant-reported water-consuming behavior to correspond well with measured data: building differences ranged from — 19% (the model underpredicts) to 12% (the model overpredicts), and the average difference was approximately 12%. These results suggest that survey information can be used for estimating hot water usage for multifamily buildings without detailed monitoring.
