Series: NILU rapport 15/2021
Prem Partners II A/S has commissioned NILU to evaluate the extent of air quality zones for the present situation concerning a possible new residential building in Bjørnheimveien 26. A Gaussian dispersion model for line sources has been applied (Hiway-2). The road E6 is in this area running over a bridge. If the elevation of E6 and the terrain around Bjørnheimveien is considered, the calculations show a significant reduction in the extend of red and yellow air quality zones at ground level. The effect of shielding existing houses from air pollution by the new building is marginal. The calculations show agreement with the current air quality map for the area when the default assumption of flat terrain is applied.
