Abstract
This paper describes wind-tunnel investigations of the wind velocity field over the roof of a model of the Aylesbury experimental house, and gives examples of data. The range of velocity variation was found to be much smaller than that of local pressure coefficients, with no consistent correlation between C p and V/V ref . The velocities were lower than predicted by the current British Standard code BS 5534 for slating and tiling. This is traced to flawed logic in the method of estimation used in the code. An empirical amendment to the currently used method of estimating local velocities is given. This gives a reasonably good fit to measured data in the central area of the roof.
