I'm trying to estimate a service size for a samll office building. My estimate works out to 10W/SF. Previous projects are all around 10W/SF. It is for a 14,800 square foot building for which I have preliminary floor plans for a small part of it (two tenents). 12 W/SF sound right? There is an elevator which I will add on top (of the 12W/SF) along with other house loads like exterior lighting.
