Wind climate: Pedestrian comfort, Lawson criteria
Wind comfort is assessed using CFD simulations to quickly and accurately provide insight into the wind climate before or during a new development. We asses pedestrian comfort on criteria like Lawson’s. Areas which are unsafe or have wind nuisance can be identified and dealt with by using trees, canopies, balcony railings etc. to overcome the nuisance.
Wind loads: High rise development, Buildings, structures, ships etc.
Wind loads assessment in the built environment is essential in maintaining safety. High rise designs, moored ships, equipment/structures mounted on high rise buildings like signage or railings are often designed based on unrealistic wind speeds which can lead to both over and underestimation of wind forces. Designing the building/structures based on realistic wind loads obtained from CFD adds another layer of certainty and hence can save costs without compromising safety.
Acoustics: Indoor acoustics, urban noise, traffic/industry noise on façade
Noise pollution in urban environment is an increasing concern to the authorities. There is an increasing demand from the authorities for demonstrating that the acoustic measures applied on balconies/windows/loggias actually work in reducing noise levels. We can not only simulate urban noise and effect of the measures but also indoor acoustic using a combination of Ray-tracing and FEM.
Air Pollutant dispersion in urban environment is an area of health concern. The accurate simulation of pollutant distributions on and near buildings is critical for building design and evaluation, especially in urban environments. CFD can play a vital role predicting pollution concentrations and their dispersion, thereby could also be used to verify building design ideas to avoid pollutant concentration near residential areas.
Building regulations: NEN-8100, NEN-1991, local authorities
Regulators publish standards for wind climate and wind loads that the building developers have to conform to. We have extensive experience in this area and can also help developers in making sure they conform to the requirements.
