Novus, as part of the Boundary Layer Wind Tunnel Laboratory Team, was retained by Gensler/Diller Scofidio to conduct a numerical exhaust re-entrainment assessment and an aeroacoustic design review of the new Roy and Diana Vagelos Medical Education Center.
Working closely with the Design Team, Novus provided consultations and detailed evaluations that included:
- Exhaust Re-entrainment Modelling for improving air quality; and
- Aerodynamic noise mechanisms.
Through initial on-site consultation and review of architectural and mechanical designs, we were able to highlight positive features of the design and identify exhaust sources and receptors (both on-site and off-site) that could be problematic. Flow visualization was performed in the wind tunnel to gain an understanding of expected wind flow patterns around the building accounting for local site conditions and meteorology. Numerical modelling was performed to determine expected exhaust dispersion and levels of re-entrainment and provide recommendations for exhaust stack and fresh air intake configurations.
Novus also completed a review of potential aerodynamic (wind-induced) noise generation by proposed fin features on the facade. Flow visualization was conducted using CFD models to predict velocity and pressure fluctuations along the face of the building for the proposed design options, and recommendations to reduce potential for aerodynamic noise generation at the building façade were provided.
