Wind comfort and safety on a building terrace (France, confidential location)
Computational fluid dynamics is a powerful tool to investigate how wind affects particular areas of a building, such as terraces, balconies, passages, courtyards, in order to guarantee the appropriate level of comfort and safety. Engineers’ expertise is fundamental to identify the architectural elements which can have a significant role in the analysis of the airflow around and inside these areas. On the basis of accurate CFD results, BuildWind engineers are able to suggest innovative or convenient solutions to mitigate possible fluid dynamic issues.
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.
The project proposes concrete, feasible and sustainable solutions in terms of structure transportation and construction, energy supply, water storage and thermal insulation.
