VA-89-10-1 — The Estimation of Wind Pressures at Ventilation Inlets and Outlets on Buildings

Description

Two example calculations illustrate the application of information provided in Chapter 14 of the 1989 ASHRAE Fundamentals to the estimation of wind pressures at ventilation inlets and outlets on the exteriors of buildings. Wind pressures are calculated using the local estimated reference mean wind speeds at the building site and pressure coefficients selected from figures provided in Chapter 14 of the Handbook. Calculations include estimation of wind speeds at building sites located significant distances from airport weather data recording stations in a variety of terrains using the “power law” mean wind speed profile equation. Wind frequency data are used to calculate the relative probability of Occurrence of wind speed and direction events. Wind tunnel studies are recommended as the best source of wind pressure coefficients for applications where consequences of wind effects could be critical.
