Implementation After awarding of the contract, contractors translated the bid specifications into Green School project, which builds on the improvement of management procedures already established. It is proposed to initiate a transformation of school buildings through a combination of Technological Innovation and Social Innovation, to make schools more efficient and sustainable through a combination of innovative technologies, and active participation of citizens/users.

The results

Objectives, developments, replicability of the model The savings in management can improve the condition of the school buildings in terms of: Quality of space Safety Further riduction of energy consumption The savings in management can improve the condition of the school buildings in terms of: Quality of space Safety Further riduction of energy consumption The model, although obtained through an evolutionary process, lends itself to be replicated, to an extent and at a time related to the maturity of the contexts. Subjects responsible for managing school buildings in the Provinces of Treviso: 95 Municipalities, in charge of more than 400 school buildings, where similar savings to those of the Province can be obtained The model, although obtained through an evolutionary process, lends itself to be replicated, to an extent and at a time related to the maturity of the contexts.

The Province of Treviso headquartes Every time we turn up the heat, the level of CO₂ emissions increases. Because heating is often produced using fossil fuels such as coal and oil. And the production process emits CO₂. The more we can reduce our dependence on fossil fuels, the more we can reduce CO ₂ emissions m² photovoltaic panels (200kW) and 1 biofuel plant (360kW) When The Province of Treviso decided to allocate and renovate an existing building complex, it was agreed that alternative sources of energy would be utilized m² photovoltaic panels were installed on a field, which together with the biofuel plants would be used to heat and produce energy to the buildings. And to minimize heat loss, a building automation system (BAS) was installed. Cooling/heating from fossil fuels equal to that of 14 single-family houses The solution above provides enough cooling/heating and energy for the 100,000 m³ building complex, that the amount of fossil fuels actually used is no more than it takes to cool/heat 14 single-family houses. The CO₂ accounts show some impressive results: The buildings emits approximately 807 tons less CO₂ pr. year. Energy and cool/heat to 100,000 m³ of buildings using no more fossil fuels than 14 single-family houses (4,458 m³)

The Province of Treviso headquartes Fuel consumption and emissions: Consumption of wood chips: approx m³ per year Production ashes: approx. 110 m³ / year Gas equivalent: approx. 300,000 m³ Greenhouse gas CO2 equivalent: approx. 700 t / year CO2 emissions to 5000 m³ of wood chips wood: approx. 70 t / year Reduction of CO2 emissions per year: 630 tons - Automated extraction ashes Reduction of CO2 emissions per year: 177 tons - photovoltaico panels Heating and energy using RES = 807 tons/y less emission of CO2 Wood chips
