Three independent and colorful comb-shaped schools, oriented towards the sun, joined by a junction of laboratories and facilities and characterized by a long glass window through which it is possible to see the big rainbow that lights up the floor. The prefabricated construction has been realized with wood and natural materials, assembled with the “CLT” was classified as “nearly zero energy”: about 1.5 liters/m² per year of fossil fuel will be sufficient to heat and provide hot water. Innovative technology and custom installations transform the building into a laboratory where children can learn how to save energy and preserve the environment.
