Analysis of energy buildings sustainability through different building automation system

The goal of this paper was to evaluate the energy savings achieved through the use of different building thermal automation systems through the use of software TRNSYS. As reference was considered a building site in Milan in a street canyon with the structural building elements required by current laws. The idea comes from the study of the European Standard CEN EN15232 "Energy performance of buildings - Impact of Automation, Controls and Building Management" which highlights how the inclusion in buildings (residential and tertiary) of Control Systems Automation and leads to a reduction of energy consumption. They then evaluate these reductions in function of the type of automation implemented. This evaluations are made only for heating system and for a residential building.
