Case study: Office environment, handling the most challenging IFC files

This case study, conducted by the University of Padua, aimed to assess the performance of two CFD software solutions (ANSYS Fluent vs. VENTO AEC) in an air conditioning scenario on a typical summer day within a real departmental office. The study involved comparing temperature values calculated by both software packages against data from seven measurement points located within the office.

Moreover, the video demonstrates our outstanding post-processing technique. 

Throughout the simulation, users can track key HVAC performance indicators.

Key parameters:

> Inlet and Outlet located at the ceiling: T=20 C, 0.55 Kg/s

> Diabatic windows with assigned transmittance

> External air temperature T=33 C

The graphs in Figure 1 illustrate wall heat transfer via diabatic windows, along with mass flow rates at inlet and outlet, and the average temperature. These visuals demonstrate a seamless convergence toward a steady-state regime.

Endorsed reliability

This case study has been developed as a Master Thesis at the Department of civil, environmental and architectural engineering of the University of Padua. Within this project, a special focus was given to a performance benchmark between VENTO AEC and ANSYS Fluent.

“VENTO AEC boasts a leaner and optimized framework, efficiently catering to the needs of professionals during performance evaluations of built environments. Analyses were carried out seamlessly, within notably shorter timeframes compared to its counterpart and full consistency. VENTO AEC’s performance is fully positive due to its straightforward and clear interface, swift execution and the quality of achievable results.”
