O-Town West Boardwalk High-Rise
Performed a CONTAM building airflow analysis to determine an appropriate stairwell pressurization system for the building.
We completed a Smoke Control Rational Analysis (SCRA) for the Boardwalk Office Building Project, part of the O-Town West Development in Orlando, Florida. This analysis specifically addressed the requirements regarding the stairwell pressurization systems which will be provided in accordance with Section 403.5.4 and 909 of the Florida Building Code. Through utilizing CONTAM (a zone based computational model), in lieu of algebraic hand calculations, we were able to appropriately size the pressurization fans taking into account interaction with one another, the building’s geometry, and environmental conditions.
Hand calculations and rules of thumb are appropriate in obtaining rough order-of-magnitude capacities for these systems, however often times upon acceptance and commissioning of such systems balancing and obtaining appropriate pressure differentials on all floor levels is difficult to achieve. A CONTAM approach evaluates these systems holistically, such as the inclusion of consideration to stack effect by analyzing the impact of extreme summer and winter temperatures, wind, and architectural features of the building.
Benefit to the Design Team
The utilization of the CONTAM approach in developing the Smoke Control Rational Analysis resulted in an expected supply capacity range for all stairwells within the building, which will greatly assist in acceptance and commissioning of the system.
