We have a new one story, unrated, fully sprinklered office building(26,000 sq.ft.) being built with S-1 and F-1 occupancies attached to it. The F-1 occ.'s are wood working and metal shops(both shops are under 5,000 sq. ft. about ), there are also elect. shops ,etc. and various storage rooms. What are the thoughts on heating and cooling the F-1 occupancies, especially with exhaust and dust control systems, Section 1204.1 (exception #1) of the CBC is pretty ambiguous. And the types of combustible control that is needed for wood and metal shops. thank you
