Following the updated guidelines in the 2012 NFPA 204 to correctly design and maintain smoke and heat venting systems.

The 2012 NFPA 204: Standard for Smoke and Heat Venting applies to the design of venting systems for the emergency venting of products of combustion from fires in buildings. Manual and computer-modeled solution methods aid in design calculations. The equations or models provide the designer with the necessary tools to develop vent designs based on selected performance objectives related to a specific building and a specific set of circumstances.

This latest edition introduces new rules for venting systems in sprinklered buildings, including:

• The venting system design must be based on an engineering analysis
• Automatic sprinkler systems must comply with NFPA 13: Standard for the Installation of Sprinkler Systems
• New Annex material
