Design Areas for a Hotel

Design Areas for a Hotel

Design Areas for a Hotel

(OP)
I'm designing a NFPA 13 system in a 6 story hotel. Level one contains the lobby, kitchen, offices, exercise rooms, mechanical rooms, etc.. On the East end of the building will be shell coverage for future restaurants/fast food joints. Levels 2-6 will be guestrooms. I will be performing the following calcs:

1- .1 / 1500 sq. ft for Lobby Areas
2- .15 / 1500 sq. ft. For the shell coverage for future restaurants
3- .1 / 4 Most demanding adjacent residential heads on level 6
4- Standpipe #1 & #2 Calcs.

My question is, on the calculations for the lobby area would I include the heads in a mechanical room/Laundry room/Kitchen area if they fall in my remote area? Or should I not include them and calculate those rooms separately? If I do calculate those rooms separately, would I have to add additional heads from surrounding light hazard areas to satisfy the 1500 sq ft. requirement?

RE: Design Areas for a Hotel

You have to calculate the most DEMANDING 1500 sq ft, not just the most physically remote. If your kitchen, mech rooms, etc are more demanding then that is the calcs you provide. If they are in your remote area, why would you not calculate them? They are going to likely flow at a higher demand than the light hazard areas. Also, can you reduce your 1500 sq ft areas by using the QR reductions?

Most demanding is what I was referring to when I mentioned my remote area. I was just confused on whether I needed to calc. the different hazard classifications separately. I will just do one calc. there instead. Also yes, I plan on using the QR reduction with 12'-6" ceilings down to 1023.75 Sq. ft.

RE: Design Areas for a Hotel

I just calc the area that is most demanding and make sure that each head has the proper flow and density.
