Troubleshooting of HVAC System Air Stratification and Building Pressurization Problems. Eight built-up VAV systems with sizes between 70,000 and 84,000 CFM each were analyzed to determine the solution for air stratification in the mixed air plenums and building pressurization problems occurring during economizer operation. The building pressurization problems prevented the elevator doors from closing properly. Recommendations were made to solve the problems along with associated construction budgets (1997). Retrofit desgin was completed including and new Building Automation System and all system control and pressurization problems were solved.
