URBAWIND, A TOOL FOR WIND FRIENDLY BUILDING
GREEN BUILDING SPECIFICATION GUIDE
LEED™ (Leadership in Energy & Environmental Design) is a rating system created by the US Green Building Council
for environmental performance using a “whole building” perspective. The software UrbaWind aims to calculate
the wind effects in urban environment. Such study makes New Construction and Major Renovation as well as
Existing Buildings eligible for credits to obtain the LEED Certification. This user-friendly tool is tuned for architects
and environmental scientists.
Indoor Environmental Quality (Credits 1, 2, 3.1, 3.2 and 7.1)
Objective:
• Increase energy savings by minimizing the use of mechanical systems for air
extraction and air-conditioning
• Respect the new standard of indoor air renewal
• Characterize the air quality (IAQ) inside the buildings (hygiene and thermal comfort)
Solutions:
• Air change rate assessment
• Modeling all opening types (section, opening level, loads coefficient…)
• Meteorological Scenarios (typical year, season, time of the day…)
• Simulation of the air flow tracks inside the buildings including multi-volumes
Sustainable sites (Credits 1, 5.1, 7.1 and 7.2)
Objective:
• Contribute to create a pleasant lifestyle
• Give value to the architectural project (conception and communication)
• Validate the city planning configurations
Solutions:
• Assessment of the discomfort criteria and computation of the discomfort
frequencies
• Possibility to integrate climatologic data
• Automatic visualization in a 3D mapping
Energy and Atmosphere (Credits 2 and 6)
Objective:
• Help the production of renewable energies
• Optimize the installation of wind turbines in urban environment
• Take part to the construction of positive energy buildings
Solutions:
• Assess the wind energy potential
• Forecast of the annual energy production
• Performance of the integrated wind turbines
