Air pollution investigation for the community centre Berliner Allee in Freiburg / Germany
Building model for air pollution analysis
Building model for air pollution analysis
DESCPRIPTION OF PROJECT
The city of Freiburg intends to build a community centre on the 'Berliner Allee'. The planned complex of buildings shall comprise supermarkets, numerous retail stores, service shops and apartments. A 6-storey car park with 750 parking lots shall hold the cars of employees, customers, visitors and residents. The additional traffic will thus lead to an increased air pollution load in the area.

On the basis of traffic surveys and forecasts, the concentration of air pollutants was determined. The concen­trations of nitrogen dioxide (NO2), benzol (C6H6), sulphur dioxide (SO2), carbon monoxide (CO) and PM10 (particles smaller than 10 microns) were estab­lished by means of the 3-dimensional dispersion model MISKAM (Microscale Flow and Dispersion Model).

Based on traffic loads, types of vehicles, driving behaviour and emission factors of the different vehicle categories, the air pollution loads in the investigation area were estimated and compared against the limit values fixed in the Federal Immission Control Ordinance (BlmSchV). The concentrations of air pollutants were displayed in contour maps.
PROJECT COMPONENTS AND
TECHNICAL DATA
  • Calculation of the concentration of air pollutants in accordance with the German Technical Instructions on Air Quality Control (TA Luft)
  • Investigation and mapping of initial immission levels
  • Application of a microscale air pollution dispersion model
  • Interpretation and evaluation of results in accordance with the Federal Immission Control Ordinance (BlmSchV)
BRIEF DESCRIPTION
Project-related studies on the development of the community centre "Berliner Allee" in Freiburg. Definition of future noise nuisance, air pollution and traffic load after the opening of the community centre and the appurtenant car park.
