The Power Law curves in NFPA 72 will give you somewhat of a correlation between heat release rates and design/density curves. SFPE published a sprinkler system design book two years ago that will help you (Designers Guide to Automatic Sprinkler Systems).
Finally, as I'm sure you remember, an office is not light hazard because you call it an office, but rather what are the quantity and/or combustibility of the contents and the rate of heat release as defined in NFPA 13. Plastic or composite furnishings, partitions, computers, etc. Are not necessarily light hazard.

The only possible answer relates to the fact that this building use is intended to accommodate OH2 commodity arrangements. Not now, but some other time. And when it does the building will not be subject to a change of use code compliance action. By the way, what is a Light Hazard fire if it were to be inserted in a fire model? Would a OH2 fire be twice the heat release rate since the sprinkler density is doubled?

The building has a separate 20,000 sqft storage warehouse in the same building but is in a completely separate area from the showroom which will be addressed accordingly. This will strictly be an entry area of the business with a SHOWROOM meaning the office products will be placed in situations like a real operating office minus all of the computers and people. The products in this room will be no higher than normal bookshelves in your own office. The following description is why I question it Occupancy type. If this were the office portion of the building then it would clearly be Light Hazard. Since the furniture is on DISPLAY and not being USED as an office then this should be Ordinary Hazard? This I do not understand. BTW, I had already laid it out and bid it for Ord Hazard Group II but wanted more input.

Maybe if they were selling angle iron out of a 10' high building, you'd have a chance for OH1. Bigbox retail, hey-class 4 25' high racks. But furniture and plastic- only in my area could you get an AHJ to sign off on LH.

Watch out for rack storage. I asked a similar regarding a jewelry store a few months back and got my you-know-what nailed to a tree.
