According to Donald G. Koch, P.E., principal, JBA Consulting Engineers, Las Vegas, the firm that provided the HVAC and smoke-management systems for the original Mandalay Bay project, as well as the expansions, makeup air velocity was a major issue.As mandated by code it can be no less than 200 ft. per min. for zones utilizing an exhaust method.He explains that since the convention center is open to the casino and the casino is open to Mandalay Place and THEhotel, wind and stack air currents have a significant effect on the air velocities between the smoke-control zones.Noting that JBA tries to simplify smoke-management systems whenever possible, Koch explains that by using exhaust or supply fans to create pressure differentials, they can avoid pressure 'sandwiches,' where the floors above and below a fire are pressurized and the fire floor itself is exhausted.
