 Wind Comfort

Typical projects:

  • Pedestrian level wind impacts around tall buildings
  • Wind impacts on sports' performance and spectator comfort
  • Sun and shadow effects
  • Glare impacts
  • Thermal comfort relating to the interaction of temperature, humidity, wind and the sun

RWDI identifies and solves problems related to:

  • Pedestrian level wind impacts
  • Sun and shadow effects
  • Thermal comfort

RWDI resources include:

Wind Tunnel Testing

Scale model testing in RWDI's wind tunnels records pedestrian level wind conditions in key areas and verifies the effectiveness of solutions.

Water Flume

Scale model testing in the water flume assesses wind flows through flow visualization and develops control measures such as landscaping and wind screens.

Computer Modeling

Simulates sun / shadow / glare patterns and provides input for thermal comfort studies.

Computational Fluid Dynamcis (CFD)

Various scenarios can be simulated using the CFD tool.

What RWDI can do for you:

Consultations / Design Reviews

Early in the design process, review information and provide recommendations to anticipate and avoid potential problems.

Pedestrian Comfort / Spectator Comfort Study

Evaluate and verify wind flows in key pedestrian / spectator areas and, if necessary, develop solutions using water flume and / or wind tunnel testing.

Sun and Shadow Modeling

Assess effects of new construction on comfort levels and aesthetics through computer simulation of sun and shadow patterns.

Glare Modeling

Evaluate glare from new construction on drivers in traffic, pilots or spectators at events through computer simulation of reflected sunlight.

Thermal Comfort Study

Assess pedestrian comfort or spectator comfort levels according to temperature, relative humidity, wind speed, sun and shadow, clothing levels, and activity levels.

Baseball Trajectory Study

Simulate the direction and distance a baseball travels under various external wind conditions for all types of hits using software developed by RWDI.

Expert Testimony

Specialists provide testimony at government hearings and court cases.
