Hi everybody,
I have modeled my primary school in Openstudio. And I would like to know how much is the annual water consumption of the primary school?
And also what is this value in Ashrae (I mean elementary student water consumption in the standard of Ashrae)? Thanks in advance.
Th ASHRAE Handbook - HVAC Applications has a Table "Hot-Water Demands and Use for Various Types of Buildings" (table 7 chapter 50 in 2011 edition). For elementary it lists a max hourly, max daily, and average daily (0.6, 1.5, 0.6) gallons per student. The book provides details on assumptions made in these numbers.
You could also look at the DOE Prototype primary school for the target standard you are interested in and scale to your building per area or student as a rough starting point.
@David Goldwasser, Thank you Davis for your response, I have two question: is these values for only hot water? But what about cold water?
@David Goldwasser, My second question: To look at the DOE Prototype primary school for the target standard, I can use Openstudio? I mean by Openstudio, can I notice daily water consumption of the primary school per students? Thanks in advance
@designer4 I'm not sure of a good source of cold water user (toilets, fountains, landscaping etc) for schools., but I expect there are some guides for that somewhere. As far as OpenStudio reporting hot water use per student, no, there isn't a report that does exactly that but you can look at total hot water consumption annually and you can look at area of classrooms and people per square foot as a starting point. Keep in mind all rooms are not at capacity, sometimes ever, and often not at the same time. (art and music room, computer lab won't be at capacity when classrooms are.
@David Goldwasser, Thank you David.
