The article presents the results of field studies of air quality depending on mobile sources of pollution. Studies of the carbon monoxide concentration was conducted for the climatic conditions of the South of Western Siberia. The object of the study was residential buildings. The studies were conducted under unfavorable wind speed. Processing of experimental data allowed to obtain the calculated dependences of dimensionless concentration of carbon monoxide (II) on the height of building’s facade under emissions from highways. According to the results of research a nomogram was constructed to determine the optimal air intake height of buildings located near roads of various traffic intensity. Research results and given recommendations allow considering external sources of pollution when designing ventilation of a building.

1. Введение
Распределение загрязняющих веществ по высоте зданий имеет определенный характер и исследовалось ранее [1–4]. Интерес представляют исследования содержания оксида углерода (II) в наружном воздухе в многоэтажных зданиях, находящихся под воздействием передвижных источников загрязнения атмосферного воздуха, что важно при выборе места забора воздуха при проектировании приточной вентиляции зданий [4]. В городских условиях ошибочно спроектированная приточная механическая вентиляция может привести к ухудшению качества воздушной среды в помещении [5–10]. На стадии проектирования системы вентиляции трудно прогнозировать уровень загрязнения воздуха по высоте здания.
Цель исследований — разработка расчетных зависимостей для выбора оптимального места забора приточного воздуха с учетом качества наружного воздуха по высоте зданий.
