摘要: Urban pollution due to roadways is perceived as a major obstacle implementing lowenergy ventilation design strategies in urban non-domestic buildings. As part of project evaluate the use computational fluid flow model an environmental tool for buildings, this paper seeks address impact from on buildings areas restricted topography and assess dominant influencing factors other requirements testing predictions. Vertical profiles carbon monoxide (CO) temperature at facade building Central London street, addition above-roof wind speed direction, were measured over period three months. The street has height-to-width (h/W) ratio 0.6 asymmetric horizontal alignment. air flows area surrounding modelled using two orthogonal directions. CO concentrations calculated steady-state field order place point measurements context field, identify persistent features data attributable structure and, by comparison with measurements, further requirements.
