Today, we bring an interesting case from our daily work on smoke ventilation projects. We were challenged to analyze the performance of a Delta system on a roof that, in addition to the smoke ventilation equipment, will also host several solar panels.
At first glance, it might seem simple. Normally, adjacent elements do not interfere with the Delta system. But in this scenario, the solar panels act as true “wind ramps,” altering the ventilation dynamics and impacting the smoke ventilation coefficient (Aa).
We conducted a detailed analysis based on the configuration proposed by the client and quickly realized that the presence of the solar panels reduced the Aa, which could compromise the system’s effectiveness. The solution involved studying different configurations and identifying the ideal height for the wind deflector to compensate for this influence and ensure the required performance.
An essential point: this solution was duly certified under EN 12101-2:2003, guaranteeing full technical compliance and all necessary safety requirements.
This project is yet another example showing how every detail matters. Adapting technical solutions to the reality of each installation, with proven certification, is what ensures safety, efficiency, and sustainability.
