Airflow Networks: J1V5, TM59 and Natural Ventilation

The Airflow Network Model offers a comprehensive approach to simulating the performance of natural and forced air distribution systems within building, with a particular emphasis on multizone mixed mode or natural ventilation outcomes.

Typically, methodologies such as CIBSE TM59 or the incoming J1V5 Verification Method use airflow networks to establish overheating risk or theoretical heating and cooling loads.

On the 16th of May, Darren O'Dea (Director) provided a practical overview of Speckel's new air flow network features that enable projects to understand and model detailed natural ventilation strategies for compliance and beyond.
