Results refer to the set of simulations carried out including
the variables above defined. A first set of calculation was
made to evaluate the performance of the green roof under different
moisture conditions. Following the energy simulation results
are presented, considering the green roof performances under
effective rainfall. The results presented the demand for heating,
cooling and energy, the latter expressed as simple sum of
the two energy uses. The calculations refer to the net energy
demand, without considering the energy systems efficiencies, in
order to focus on the envelope behaviour. The same simulations
are presented in free floating conditions, in order to evaluate
the improvements of comfort conditions using cool and green
roofs.
