PURPOSE OF THE PROJECT Collect data on when water is flowing at fixtures to calculate the probability that the fixture is busy. The fixture p-values is on of the parameters to predict peak demand in buildings for pipe sizing purposes. ORGANIZATIONAL STRUCTURE: Each .csv contains colated raw data from a wireless sensor network deployed at the Marian Spencer Hall cafeteria restroom at the University of Cincinnati, Ohio. FILE NAMING CONVENTION StartDate_EndDate(MMDDYYYY)_Building_Location_FixtureType_NumberofFixtures (e.g. "08192022_12082022_MarianSpencerCafeteria_MensRestroom_Lavatory_2") METHODOLOGY/PROTOCOL DATA COLLECTION:Please refer to NIST GCR 00-XXX report onResearch on Fixture-Level Peak Probability of Use in Commercial Buildings for information on experimental set-up and the data collection procedures. DATA EXPLANATION, OMISSIONS AND ERRORS Each data file has 5 coulmns. Columns [1] EventNumber, [2] Date, [3] EventStartTime [4] EventEndTime and [5] Duration of flow (secs). Since the location is often closed for breaks and holidays, the data collected is not continuous. That means over the either sampling period, several days data are missing.
