 Air Quality (Architectural / Engineering)

Typical projects:

  • Laboratory exhaust being re-entrained into building fresh air intakes
  • Traffic exhaust impacts on building fresh air intakes
  • Kitchen odors affecting nearby living or working areas
  • Contaminated air from incinerators, cooling towers, boilers and generators impacting pedestrian areas and fresh air intakes
  • Interior pollution sources dispersing through building affecting occupants

RWDI identifies and solves problems related to:

  • Stationary and mobile exhaust dispersion
  • Dust
  • Odor
  • Accidental spills and releases

RWDI resources include:

Computer Models

Large suite of advanced computer models resolve air quality impacts close to the source or region wide.

Wind Tunnel Testing

Scale model testing in RWDI’s wind tunnels solves problems related to the impact of exhaust dispersion in complex situations

Computational Fluid Dynamics (CFD) Testing

A sophisticated computer simulation technique predicts complicated flows and particulate motion in localized areas.

Field Monitoring Equipment

Continuous monitoring systems and sampling programs quantify emissions, and determine pollution levels and the effectiveness of abatement programs.

What RWDI can do for you:

Consultations / Design Reviews

Early in the design process, information is reviewed in order to anticipate and avoid potential problems.

Exhaust Dispersion Studies

Computer modeling and/or wind tunnel testing is used to identify the extent of any air pollution impacts and to provide solutions.

Odor Assessments

Odor sources are identified, solutions developed, and odor panel assessments undertaken to determine the extent of the problem or the effectiveness of solutions.

Air Quality Measurements

Existing or background levels of contaminants are determined.

Environmental Impact Assessments

As part of the Environmental Assessment process, services are provided for air emissions, particulate, toxic gases, and odor complaints.

Risk Assessments

Risk is predicted through research and computer modeling, and recommendations are provided for preferable alternatives and evacuation planning.

Certificates of Approval / Permitting

Assistance is provided to obtain government approvals to discharge a pollutant for renovations and for new construction of emission sources.

Emission Inventories / Environmental Audits

Using GIS software, emissions are catalogued, classified according to importance, and problem sources are identified for further evaluation.

Expert Testimony

Testimony is provided by specialists at government hearings and court cases.

Air Pollution Control

Air pollution control systems are designed and procured.

Emission Testing

Source sampling is used to determine compliance with regulations and existing control efficiency.

Dust Control Studies

Fugitive dust impacts are evaluated and control methods are recommended.
