I am working on designing an assisted living facility. I am debating whether or not the demand factors or the optional load calculation methods for multifamily dwellings apply. This unit has 59 living units. Only 17 have permanent cooking appliances. The facility has a lot of "commons" areas as well as a full kitchen facility. I understand this is not a multifamily dwelling occupancy. However, from a load perspective I don't see why the optional method would not apply to the living unit portion of the load as long as you assume each of the 59 units has an 8 KW range (per 220.84(2) Exception. It seems like massive overkill to assume all 59 of the living unit HVAC units will be sized at 100%? If you cannot use the dwelling unit portions of Art. 220 for this application, I have to assume the 17 ranges are "commercial cooking equipment" and apply the demand factors of Article 220.56. This does not seem reasonable either since these ranges are definitely not commercial cooking equipment. I appreciate anyone's opinion or experience with this type of application.
