Development and evaluation of the ADMS building effects module
The structure and algorithms which comprise the ADMS building effects module are summarised and their performance illustrated against ground-level concentration distributions for seven test cases. Overall, this reveals a mean bias up to a factor of 3, being on average a factor of 2 in the near-wake and 0.7 in the main-wake. Some issues that arose from the model development and application are then analysed. Finally, general limits on the performance of building effects models are discussed.
