In Italy there are other examples of excellence built in the last years: the di Ravenna, certified as Energy Class A; the two stores of Viverone Est and Ovest (on the A5 highway connecting Ivrea to Santhià) both equipped with geothermal plants, a solution that cuts energy consumption by almost 30% compared to traditional stores; the Dorno and Brembo stores, where the installation of methane-fired trigeneration plants for the cogeneration of thermal and refrigeration energy resulted in reductions of 131.7 kg and 115.7 kg of CO2 emissions in 2012; the Montefeltro ovest store, near Riccione, certified as Energy Class B, whose design optimized the investment by square meter, particularly in relation to the climate control system, which concentrates 75% of the total dispersion.
