Provost Square Powerhouse Theatre

PROJECT OVERVIEW

Provided fire and egress modeling to determine a smoke control system for a performing arts theater.

The Approach

Fire & egress modeling was utilized to determine the required exhaust capacity and makeup air to serve as smoke protected seating and stage exhaust for the performing arts theater.  A common path of travel of 50 feet (extended from the code allowed 30 feet) was desired by the design team, thus triggering the smoke protected seating requirements (2015 IBC Section 1029.8, Exception 2).  Algebraic hand calculations utilized to determine the required exhaust capacity resulted in quantities in excess of 200,000 CFM.  The completed fire and egress modeling approach resulted in 60,000 CFM, a 70% decrease from the hand calculations.  This resulted in extensive savings due to fewer, smaller exhaust fans, as well as decreased natural makeup air requirements.  Makeup air was determined from the fire modeling approach to be sufficient from doors leading from the theater seating spaces to the lobby, and from the lobby to the exterior.

Estimated Cost-Savings

It is estimated that the 70% reduction in mechanical exhaust capacity, and thus decreased natural makeup air, resulted in savings in excess of $200,000 to the owner.
