HVAC Building Pressurization Systems, by Erich Binder

Wed April 5 at 11:30a

This month’s chapter program will give us the opportunity to learn more about HVAC building pressurization systems and lessons learned.

A recent audit of 35 existing buildings have known pressurization's issues including:

• Over Pressure of buildings often to much make up air.

• Under Pressure in building due to leaks, inadequate HVAC, poor construction, on site modifications.

• Improper HVAC Economizers operation (waste heat recovery.)

• Poorly controlled, designed and or constructed relief systems.

• Commissioning and Operation issues.


Pressurization is a critical for maintaining room cleanliness in Labs, Hospitals, Processing, Manufacturing, Control, Computer, MCC, VFD & Electrical Buildings, etc.

Design margins should be incorporated in the pressurization system to allow for building envelope seal degradation.

When pressurization is required for safety or code compliance, make provisions for periodic surveillance & testing.

Critical facilities require a leak test of exterior & interior walls, partitions, doors, and windows between two adjacent areas with different pressurization levels & any building elements between two areas with different pressurization levels.

Speaker Erich Binder is an independent engineering consultant with an extensive experience in in the sustainable design of Commercial, Institutional, Industrial, & Cold Climate, Heating Ventilation & Air Conditioning (HVAC), Plumbing, Fire Suppression & Specialty Mechanical Systems engineering. Erich has also a Certified Risk Manager with over 20 years of Process Safety, Loss Prevention, Industrial Hygiene, Health & Safety Engineering and Auditing experience.


Professional Development Certificates (1 hour) will be provided after the webinar.

Reservations: RSVP no later than 4:00pm Tuesday April 4 via email to Tricia King  patricia.king@rockwellautomation.com or call 423-596-0736 (NEW NUMBER).
