Effects of different building automation systems on the energy consumption for three thermal insulation values of the building envelope

The goal of this paper was to evaluate the energy savings achieved through the use of different building thermal automation systems by means of software TRNSYS. The reference building is sited in Milan in a street canyon and it’s thermophisical caratheristics of the envelope are as current law require. 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 and Automation lead 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.
