    I think that number is a rule of thumb. It really depends on temperature and dew point, clothing, etc. The warmer people get the more latent they shed.
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.

    I used 450 BTUs per person, considering that they are inactive during a wedding. 200 sensible and 250 latent.

    My factory uses a trailer mounted rental unit for one particular area every summer. they of course could have paid for a full installziton by now...but you know how budgets and bean counters can be.

    I think you typically can rent units with capacities ranging form 10-500 tons. They can be powered from electrical (probably not an option in a small church along with cost of installing the electrical) or have their own diesel generator.

    They aren't nessesarily loud, but not really quiet either.

    Being hot at a wedding isn't fun for anyone with all the formal attire. As a groom you'll be sweating a bit even if it was and outdoor wedding in Alaska in Jan.


    Now, if you have deep pockets or can get some donation together and maybe match it up ot a certain amount, it might be worth doing a permenant installaion for the church as a donation and write it off at tax time.

    For a more accurate number you could ask the guests for their height, weight, age and gender as a requiremnt for attending. It would cut down on the guest list and help the OP pay for the rental AC unit. One quick way to reduce heat gain.

    Mommas crying, daddies nervous, kids restless, friends wondering "when will this end? When's the reception?".... suits... I hate suits.
