Full-scale measurements of convective energy losses from exterior building surfaces

Abstract An experiment is described which measured the forced convective heat transfer coefficients at several positions on the facade of a 78 m high slab-type building. The coefficients are correlated with wind speeds recorded 1 m from the building's surface, 6 m above the roof and a local weather station. The effect of wind direction and facade location are discussed. Existing designvalues of forced convective coefficients are found to be of correct magnitude, even though the source of these values are physically unrelated to actual buildings.
