Abstract A question that arises in wind tunnel testing of buildings is how to take into account the changes in wind load that might occur as a result of future buildings being built nearby or existing buildings being demolished. This paper addresses this question in so far as it affects cladding loads. The implications of applying a “lower cut off” to peak suctions determined from wind tunnel tests is explored in the context of structural reliability. It is found that high overload situations caused by future buildings are largely avoided when a “lower cut-off” is applied to wind tunnel results. Also, a technique of “correcting” wind tunnel results by an amount equal to the estimated increase in load factor due to future buildings is examined. While slightly more complicated to apply, this last approach is better in providing more uniform structural reliability.
