CFD can simulate ventilation systems for complex and large buildings and infrastructures such as tunnels and offices, demonstrating what comfortable temperatures and air speeds can be maintained, and optimizing the overall strategy.
Occupant's thermal comfort and indoor air quality are the primary objectives of HVAC design for buildings and vehicles. Using simulation results designers can assess a variety of comfort criteria by predicting indoor environment conditions (air velocity, temperature, humidity, thermal radiation, pollutant concentration).
For high-performance HVAC systems such as radiant heating and cooling, underfloor air distribution (UFAD), and natural ventilation and hybrid systems that use both natural and mechanical conditioning of a building, it is critical to understand how the air flows and the surrounding environment impacts the occupants' comfort. Computational Fluid Dynamics (CFD) simulations are the best available technique to investigate the performance of such systems.
Himalayan mountain hut
This study has been commissioned by Sara Gottardo, an architect based in Paris, for an international architectural competition. Participants were asked to submit clever and inventive proposals for a feasible and efficient Himalayan Mountain Hut to be positioned along any of the trekking trails in order to provide trekkers safe, comfortable and inviting lodgings. The core of this project is the dome. BuildWind performed simulations of the aerodynamics and heat transfer in order to assess the technical feasibility of the project. The concave interior creates a natural airflow which allows the hot and cool air to flow evenly throughout the dome with the help of return air ducts, and it reflects and concentrates interior heat, preventing strong radiant heat loss.
