21 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)

22 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
