CPP advances its reputation as an essential voice and leader in the wind engineering and environmental industries. The paper PRIME2: Development and evaluation of improved building downwash algorithms for rectangular and streamlined structures, written by CPP’s Dr. Ron Petersen and Dr. Sergio Guerra, is now published in Journal of Wind Engineering & Industrial Aerodynamics. The…
Since the mid-90s, the US EPA has recommended the AERMOD atmospheric dispersion modeling system for estimating the impact of new or existing sources of pollution on ambient air quality. But AERMOD is far from perfect, and recent CPP studies have revealed key shortcomings, documented in the August issue of the Journal of Air and Waste…
Are you trying to demonstrate modeled compliance by increasing stack heights or installing additional emission control? If so, you are probably trying to overcome the flaws in AERMOD that result in predictions that may be 2 to 8 times higher than reality. Rather than finding solutions to overcome the flaws in the model or installing…
Every hospital, power plant, lab and industrial facility built in the United States must comply with air quality regulations. This may also include compliance with the National Ambient Air Quality Standards, or NAAQS (pronounced “knacks”). The NAAQS became law with passage of the Clean Air Act of 1970 to protect outdoor air quality, and the…
