Hot Water Use in Hotels, Results of ASHRAE Research Project 1544, Part 4 of 6: Comparison of Travel and Business Hotel Hot Water System Monitoring Results (RP-1544) (LB-17-012)

Information on hotel hot water use patterns has been limited until now, resulting in most hotel hot water systems being designed using extremely old hot water use data (45-80 years old) that predate the introduction of water and energy efficient fixtures and appliances. In recognition of this fact, ASHRAE funded research project 1544 “Establishing Benchmark Levels and Patterns of Commercial Hot Water Use – Hotels” to both develop a monitoring methodology that could be duplicated by others to collect hot water use data from a larger number of hotels and to obtain updated hot water use information from at least two hotels. This paper compares hot water use results collected for a “travel” hotel which had neither meeting rooms nor food service and a “business” hotel which had both.
