Why Ventus?
Ventus is developed by a team of experienced engineers and software developers to address the specific needs of building safety engineers and airflow modeling professionals.
Ventus helps you design air handling systems to manage airflow and prevent the spread of contaminants inside of your building spaces. Simply draw Zones in the building, connect with Flow Paths, and set any weather and wind Scenarios. Use simple Air Handling Systems or draw custom duct systems.
By strategically managing airflow during emergency scenarios, the systems you design will be able to maintain tenable conditions in critical Escape Routes, including Stairwells, Shafts, Atria, and Underground Facilities. Avoid a cascade of hazards, from obscured visibility that hinders evacuation efforts, to respiratory distress and incapacitation.
Ventus leverages the power of CONTAM to provide you the insights necessary to perfect your system designs. With the streamlined user experience, visualization and communication tools, and detailed analysis available in Ventus, you can cut 30-50% off the time spent on your smoke control projects and air quality studies, freeing up valuable resources and accelerating project timelines.
