UrbaWind: The automatic CFD software to computethe wind in any complex urban area
Release UrbaWind 2.2 September 2014
www.meteodyn.com [email protected]
Complement to dynamic thermal simulation softwares
Pressure coefficients on walls have to be assessed to compute the air change rate of buildings in complex urban area. Tables given as examples in Energy + (C.f. AIVC tables) shouldn’t be used by designers for any cases.
UW becomes a complement to dynamic thermal simulation software such as Design Builder, Virtual Environment, Pléiade, etc…
Wind computations Pressure field on building Cp value on each openingFor every wind incidence

Improve the access to Energy +climatological database
UrbaWind 2.2 now reads any Energy + weather files (*.epw format)
Read the climatological data and export histograms and wind
Pedestrian comfort Small wind energy Natural air ventilation
CFD (wind in urban area) Climatology data Synthesis

New porosity classification for trees and edges
UrbaWind 2.2 introduces differences between trees and edges to compute the effects of vegetation on the wind pedestrian comfort
Meteodyn calibrated the various porosity models with available physical data: urban grove of trees, isolated trees, urban edges

Improved statistic tool for air change rate
UrbaWind 2.2 introduces a new module to assess the cross ventilation bycomputing the air change rate statistics of buildings
Select the time period (day, night, season, month,…) and highlight the air change rate statistics on the period (average, minimum)

New graphic tools to mergesurfaces of interest

UrbaWind 2.2 visualisation tool allows to select many surfaces of interest at the same time to make diagnostics more easily
Main surface
Secondary surfaces
Others developments
UrbaWind 2.2 introduces new features: New inlet profiles for turbulence (4 roughness classes) Pressure coefficient depends on the inlet wind profile deduced from the ground roughness Improvement of the visualisation of climatological data, of openings, of buildings (new lighting tools) New export tools for pictures and projects
