(Anglais) In prospect of sustainable urban densification, a tool aiming to assess and to assist the design of compact housing blocks with a target population density was created and tested in the scope of the CoMod Project. The concept of spatial compactness is here applied, at the architectural scale, on the built environment, the non-built environment and both combined. This approach encourages typo-morphologies which save land and material resources while achieving high energy efficiency. Potential misuse of the concept is prevented by numerous objective criteria notably relative to green areas, projected shadows as well as minimal distances and surfaces to consider. However, targeting urban compactness faces a difficult conciliation between various quantitative and qualitative parameters. Numerous mathematical tools have already been applied on the problem of urban planning (using optimization methods, multi-criteria decision help, cellular automata, fractal sets, etc.). The study of compact typomorphologies with the help of game theory or local search can help solving the problems that arise when dealing with conflicting criteria. We are currently developing a prototype of software that generates urban blocks using local search algorithms and game theory methods.
