Air pollution control

Clean air starts with accurate forecasting

The Air Pollution Control Division focuses on protecting against harmful environmental impacts caused by air pollutants. This includes the preparation of emission forecasts and expert reports for regulatory approval procedures. We support the entire permitting process and provide air pollution forecasts for facilities and traffic to assess air quality and ensure compliance with legal requirements. In addition, our experts assist in preparing solvent balances and complying with the 31st BImSchV (Solvent Ordinance) to limit emissions of volatile organic compounds.

Our Consulting

For permit-compliant solutions in air pollution control

Both the determination of required chimney heights and the assessment of airborne pollutants and odors within approval or planning procedures require precise forecasting models and deep technical expertise. Müller-BBM Industry Solutions GmbH supports you with quality-assured dispersion calculations and legally sound expert reports—even under complex boundary conditions such as cold air dynamics or challenging topography.

  • Model Selection & Application
    Use of appropriate dispersion models (e.g. AUSTAL, LASAT, WinMISKAM, METRAS, PROKAS, LASPORT, KLAM_21) depending on emission source, substance properties, terrain, and meteorological conditions.
  • Consulting for Complex Conditions
    Consideration of building influences, steep terrain, cold air drainage, time-variable emissions, and special substances.
  • Chimney Height Determination
    Calculation of required discharge heights according to Section 5.5 TA Luft and VDI 3781 Part 4, ensuring unobstructed exhaust dispersion and sufficient dilution—both in standard cases and special situations such as sources with low or infrequent emissions.
  • Mesoscale Wind Field Modeling with METRAS
    Creation of wind field libraries using the METRAS mesoscale prognostic wind field model to account for dynamically induced flow patterns in steep terrain or terrain-climate-driven wind systems (e.g. cold air flows) as a basis for impact forecasts in complex terrain.
  • Microscale Wind Field Modeling
    Flow simulation using the MISKAM microscale prognostic wind field model to account for building-induced flow effects in cases where sources and receptors are strongly influenced by surrounding structures.
  • Cold Air Modeling with KLAM_21
    Simulation of nocturnal cold air drainage to assess pollutant transport into sensitive areas (e.g. residential zones, FFH sites); integration of cold air flows into LASAT for realistic forecasting of additional and total pollutant loads.
  • Evaluation According to Applicable Guidelines and Standards
    Assessment in accordance with TA Luft, 39th BImSchV, LAI guidelines, and VDI standards.
  • Application Areas:
    • Approval procedures under the Federal Immission Control Act (BImSchG)
    • Urban land-use planning
    • Building permit procedures
    • Air quality plans, urban and traffic planning

Air Pollution Forecast for Industrial Facilities

An air pollutant impact forecast for industrial facilities is an assessment of expected air pollutants and odors that may be emitted by a planned installation. These forecasts are especially important when direct measurement of air quality is not feasible—such as in the case of new facility planning or during zoning and spatial planning procedures.

We support you in communications with authorities and throughout public consultation processes. Our experts analyze the additional environmental burden caused by emissions and assess it in the context of existing background pollution.

Quality builds trust: Dispersion calculations in accordance with TA Luft, using VDI 3783 Part 13, are part of the accreditation scope of Müller-BBM Industry Solutions GmbH under DIN EN ISO/IEC 17025 in the field of environmental meteorological assessments.

Your Benefits:

  • Efficient project execution: With our support in dealing with authorities and public procedures, the approval process is accelerated and simplified—saving time and resources.
  • Early identification of issues: Forecasts help detect potential environmental impacts early, allowing for timely planning of mitigation or avoidance measures.
  • Optimized facility design: The results of the forecast can be used to optimize the design and operation of the facility, minimizing emissions and reducing environmental impact.
  • Improved public acceptance: A well-founded forecast can increase acceptance of the project among the public and authorities by creating transparency and demonstrating that environmental concerns are taken seriously.

Air Pollution Forecast in the Transport Sector

An air pollutant impact forecast for the transportation sector is an assessment of expected air pollutants that may result from traffic. These forecasts are particularly important for evaluating environmental impacts in planning processes, such as infrastructure projects in the transportation sector.

Our experts calculate traffic-related emissions and the resulting immissions. Depending on the specific question, we use methods ranging from simple screening models to complex flow and dispersion simulations. We also support the design of appropriate protective measures.

Quality builds trust: Air pollutant forecasts in the transportation sector using VDI 3783 Part 14 are part of the accreditation scope of Müller-BBM Industry Solutions GmbH under DIN EN ISO/IEC 17025 in the field of environmental meteorological assessments.

Your Benefits:

  • Optimized traffic planning: The results of the forecast can be used to optimize traffic planning, minimizing emissions and reducing environmental impact.
  • Targeted mitigation planning: The forecast enables the precise planning and implementation of protective measures, effectively reducing environmental burdens and improving the quality of life for affected residents.
  • Cost optimization: The forecast allows for accurate sizing of necessary protective measures based on actual needs, helping to avoid unnecessary expenses and optimize implementation costs.

Integrated Services in the Approval Process

Expert reports play a central role in approval procedures, as they form the basis for official decisions. Below are some specific types of expert reports commonly required in such processes:

Müller-BBM Industry Solutions can provide all these services from a single source.

Your Benefits:

  • Consistency and quality: Ensuring all reports are prepared to the same high standards, enhancing the consistency and reliability of results
  • Efficiency and time savings: Eliminating the need to coordinate between multiple experts, speeding up the process and simplifying communication
  • Cost savings: Bundling services is more efficient than commissioning reports from different providers
  • Coherent reporting: Better alignment and coordination between different expert reports
  • Single point of contact: One dedicated contact person for all questions and concerns, making collaboration easier and reducing misunderstandings

Chimney Height Calculation

Chimney height calculation is a key component of environmental protection, especially in industrial and commercial processes. It ensures that exhaust gases are properly dispersed and sufficiently diluted to minimize environmental impact.

Our experts take into account all relevant emission parameters and environmental factors to provide tailored solutions for each facility.

In particular, for installations with low emissions or infrequent operation—as well as in other special cases—the standard determination of chimney height based on VDI 3781 Part 4 and Section 5.5 of TA Luft may result in disproportionately high discharge heights. In such cases, it is possible to assess whether a lower chimney height can be justified from an environmental protection standpoint, considering the specifics of the individual case.

Müller-BBM Industry Solutions uses a wide range of state-of-the-art dispersion models and methods in addition to the standard reference implementations from the German Environment Agency (BESTAL) and common software tools based on VDI 3781 Part 4, to ensure accurate results even in complex individual cases.

Your Benefits:

  • Legal certainty: Compliance with all legal requirements and guidelines minimizes the risk of delays and legal issues.
  • Optimized planning: Our well-founded calculations enable optimal chimney design for effective emission dispersion.
  • Tailored consulting: With many years of experience, we offer customized solutions and comprehensive advice—even in challenging individual cases—to determine an appropriate discharge height for your emission sources.
