Wind Testing for Building HVAC
Time & Location 3:30PM - 4:30PM | Room 318B

Pragmatic Professional Engineers

Studying how outdoor air flows over buildings is critical for certain facilities in order to understand how exhaust disperses from the building or how a building can affect air velocity and quality at pedestrian levels. While computer modeling is an option for knowing how a building affects the environment at distances far downstream of a facility, there remains only one reliable method for knowing the effects at neighboring building openings or at air intake locations of the same building: wind tunnel testing.

This presentation will describe the basics of atmospheric boundary layer wind tunnel testing. After introducing the concepts and basic structure of these wind tunnels, the discussion will move on to what kind of information is required for an accurate model and what deliverables come out of the modeling exercises. Strategies of how to minimize costs of this testing as well as the types of facilities where it is warranted are also included to give architects and engineers enough information to introduce this service to their clients.
