The urban fabric plays a fundamental role in convective and radiative heat exchanges between buildings. The main parameters which influence these heat exchange mechanisms are due to climate conditions such as air temperatures/humidity, wind speed/direction and solar irradiance. These weather data are related on where our cities are located rather than on how they are built.

For the design of new buildings or buildings undergoing major renovations, the use of building performance simulation (BPS) tools is a key instrument to sizing the envelope or to select the best solution to be integrated. Nowadays, many BPS tools are available and are used by researchers and designers, each of which was independently validated, by considering different operating conditions, and rarely were directly compared in the same conditions.
