Pedestrian Comfort Study for Entrance to Building (Seattle, WA)
Computational Fluid Dynamics (CFD) modeling and wind-climate analysis were carried out to analyze the frequency of high winds at the surface surrounding a new building. In this case the primary entrance was to be located near an architectural feature that was anticipated to result in accelerated winds, causing potential difficulties for pedistrians entering the building. In addition, the building was located at the top of an exposed hillside, which would also increase the expected windspeeds. The street-level winds near the doorway and along the sidewalks were analyzed under exected high-wind conditions. The study found that the street-level windspeeds would exceed acceptable levels only under rare conditions.
 Laboratory Building Remodel Cross-over Analysis (Seattle, WA)
Provided support for the mechanical engineering design for remodeling a University laboratory/classroom building. This previously naturally-ventilated building was converted to mechanical ventilation, requiring new air handling units, cooling towers and lab hood vents. Because of the unique roof configuration, ensuring cooling tower and lab hood exhaust plumes would not reach the air intakes required a micro-climate study and computational fluid dynamics (CFD) modeling of air flows around and over the building. Working closely with the owner, mechanical engineer and architect we were able to find and implement a design that limited the risks and met other design constraints.
Wind Loading Study for a High-Rise Building (Seattle, WA)
CFD modeling was performed to provide the International Building Code-required analysis of wind loading on a new high-rise building. The highest wind-induced pressures and the distribution of pressures over the building surfaces was simulated in CFD. The results were used by the structural engineer to determine the cladding attachment systems for different portions of the building.
 Sampling System Development
Developed the High Volume Small Surface Sampler (HVS3) for the U.S. Environmental Protection Agency to measure levels of surface deposited dust and conducted several studies to validate the HVS3 in the field. An ASTM method has been adopted, establishing this as the preferred method for measuring surface dust.
