N1 - The ICTP Italian Labs Program supported M. S. Imbabi, while on sabbatical leave at Universita di Trieste. Natural Sciences and Engineering Research Council of Canada, through the International Collaborative Research Grant No. R0090041 facilitated the two-month stay of A. C. M. Sousa at University of Trieste. The computational work was performed at Computer Centre of the University of Trieste, and the Consiglio Nazionale delle Ricerche (Italy), CNR Grants No. 88.02502.07 and 87.01834.07, provided partial funding to the project.

N2 - A new bioclimatic building concept based on solar driven ventilation is analysed through the use of physical and numerical modelling. Measurements are conducted for a 1/12th laboratory scale model designed to replicate the full-scale prototype and its microclimate. Predictions are obtained by employing advanced Computational Fluid Dynamics (CFD) techniques, and the experimental results provide the benchmarking required in the development of the numerical model, which may offer a viable alternative to expensive and hard to set full-scale tests. The combination of laboratory and computational results gives additional physical insight into the prevailing phenomena determining the ventilation levels, and a first assessment on the feasibility of the concept. Comparison between predictions and experiments indicates a very favourable agreement.
