Multicriteria optimisation of the building arrangement with application of numerical simulation

This paper presents an example of the optimisation of two building arrangements as a function of three variables describing their alignment relative to each other and relative to North. The presented results are limited to the wind flow speeds around buildings in flat undeveloped terrain. The turbulence model K-ε has been adopted for this study. Calculations have been made with the use of simulation program FLUENT 4.3. The potential application of a multicriteria optimisation method for the selection process of the optimal arrangement of buildings which would provide required wind comfort has been investigated. Computer program CAMOS (Computer Aided Multicriterion Optimisation System) has been used for the optimisation procedure.
