Stack heights, air-intake locations and indoor air quality
- Cermak Peterka Petersen, Inc., Fort Collins, CO (US)
Toxic and noxious chemicals are often used in many laboratories, manufacturing plants, and other industrial facilities and these chemicals are typically vented from roof-mounted stacks. A primary consideration is to design a building and a building exhaust system such that these chemicals will not reenter the building through the fresh air intake system and thus cause an indoor air quality problem. Another design consideration is to insure that these chemicals do not cause problems at locations accessible to the public. The controllable variables affecting the concentrations at sensitive locations are the exhaust stack height, the density of the exiting gas, the ratio of exhaust velocity to wind speed, the stack location, the emission rate of a pollutant in the gas stream, the air intake locations, the shape of the building (referred to as massing), and the location of the building on the project site (referred to as siting). The uncontrollable variables include the wind speed, degree of atmospheric stratification, and the wind direction. Included in this paper is a brief description of past methods used to determine required stack heights and air intake locations, numerical and wind tunnel modeling. ods, and results from two applications of the method.
