Pitt County Jail – Flow Meter Results
Pitt County Solar Hot Water System Rendering
Good news!!! After a few hours of evaluating the raw data retrieved from the flow meter that we installed in the mechanical room of the new Pitt County Jail Annex, we have been able to determine some very important things. Over the 123 hour period that we had our ultra-sonic meter attached to the facility’s hot water line, we recorded an overall measurement of 24,700 gallons. Regular readers of my blog may recall that assessing a building’s daily consumption of hot water (usually measured in gallons per day) is the critical first step in properly designing a solar water heating system. What is especially interesting about this data is what it tells us about the hot water consumption on a ‘per person’ basis. We know that the new jail section has a steady population of approximately 200 inmates. So the average hot water usage per inmate ends up being around twenty-four gallons per day. Is this typical? It’s hard to tell without more data from other jail facilities but these numbers are in agreement with past estimates given by ASHRAE.
