The BIM (Building Information Modeling) offers a new organizational model in the construction world.

The concept of Nearly Zero Energy Building (NZEB) was introduced in Europe in 2010 with the Energy Performance of Buildings Directive (EPBD).

The European Directive 2010/27 on “energy end-use efficiency,” transposed by Legislative Decrees 102/2014 and 141/2016, introduced the energy diagnosis as a tool to understand the energy consumption of a building or group of buildings, an industrial or commercial plant, and public or private services. It identifies and quantifies energy-saving opportunities based on a cost-benefit analysis.
