 Exhaust Stack & Air Intake Solutions

Typical projects:

  • New laboratory buildings surrounded by older facilities on campuses
  • Fresh air intakes located near external contaminant sources
  • Vehicle exhaust from transportation facilities
  • Kitchen exhaust odors
  • Helicopter downwash impacts
  • Idling vehicle exhaust impacts

Contaminated exhausts can enter air intakes or impact pedestrian areas causing odor complaints and adverse health effects.

When dealing with these issues, complex wind flows around buildings must be considered.

RWDI identifies and solves problems related to:

  • Diesel generators
  • Boilers
  • Loading docks
  • Kitchens
  • Incinerators
  • Helicopters
  • Laboratory fume hoods
  • Vivaria / animal holding facilities
  • Cooling towers
  • Parking facilities
  • Local traffic
  • Isolation rooms

RWDI resources include:

Design Reviews

Specialists review drawings, inspect the site, and provide on-site feedback to the design team. RWDI identifies issues, establishes criteria, and provides solutions where appropriate.

Numerical Dispersion (Wind Wake) Assessment

When additional analysis is required, and building geometry and surroundings are less complicated, RWDI applies proprietary numerical models. The firm brings more than 20 years of experience to such projects.

Wind Tunnel Testing

Wind tunnel modeling is the most accurate tool for measuring exhaust dispersion. Physical scale models are tested in the wind tunnel when the building or the surroundings are complex and a higher level of precision is required.

Client benefits:

  • Minimize health and odor impacts
  • Strike a balance between the aesthetics and engineering design
  • Avoid costly retrofits
  • Avoid costly facility over designs
