I've been keeping this in my bookmarks for my next commercial kitchen to model:

The spreadsheet here has lots of collected data on typical/baseline kitchen equipment.  More on their website to read up on to see where they're coming from.

Hi;

I would suggest  AO Smith water heater and boiler  manufacturer sizing software available on line at

http://www.hotwatersizing.com/Application.aspx


I have designed and installed several projects including an office building cafeteria with gas fired
water heaters combined with a 750 gallon per day Solar thermal array. using AO Smith.  Good Stuff.

bye.

This is a screenshot from the 2010 Buildings Energy Data Book put out by the Department of Energy - it might be useful to you for an average estimate.

Overall - it's a really useful publication and its free. http://buildingsdatabook.eren.doe.gov/DataBooks.aspx

I believe ASHRAE text books have a DHW/person table for various building types. I know they have hotels, dormitories, and apartments. Need to check on a restaurant setting.

Is it an existing building? If so, another way to approach it would be to get an idea of the baseline(non-heating) natural gas usage from the utility data(pick a late spring or early fall month when school is in session), which would be made up of domestic hot water + cooking. Dhw is easier to estimate per person, and subtracting that, you could get an idea of the cooking use(I know you're not using eQuest, but you could start w an eQuest default for per person hot water use in a school) . Both cooking + dhw are probably fairly small.

I have to model a building according to Annex G of ASHRAE 90.1-2007. In that building there is a school canteen. The food is prepared with natural gas. How could I estimate the energy that is needed for the meal of one person?
