The GDF and GCF are two factors invented and designed by German Architect and Developer Florian Betzler. They demonstrate the possibilities to cool the microclimates of hot cities and let estates function as cooling units within an overheated climate for any city, starting from a small scale and ending with megacities. The GDF and GCF emphasize the potentials of plants as a generally required implementation into future city planning and individual architecture, aiming towards a clean, healthy, cool and beautiful urban habitat.
