1. Paving the way for self – sufficient regional Energy supply based on sustainable concepts and renewable energy sources “Green Schools” In the Province of Treviso Antonio Zonta Treviso www.manergyproject.eu

2. The Province of Treviso • Inhabitants: 888.249 • Area: 2.476,68 kmq • Density. 358,65 inhab./sq.km • 17th mostpopulated province in Italy 14th mostdenselypopulated • 95 municipalities (of which 13 enclose High School buildings)

3. The buildings under management • Typology • High School buildings, 41 schools, distributed in 13 municipalities in the Province of Treviso • Office buildingsconcentrated in the new headquarters complex and in a few external offices.

6. The Integrated Global Service OBJECTIVES SOLUTIONS Reduction of operating costs and energy consumption EPC: Energy Performance Contractwith a minimum level of consumption reduction and sharing of economies (SharedSavings) INTEGRATED GLOBAL SERVICE Attention to the interaction between user and building according to a sustainable vision CP: CommunicationPlan oriented to the active involvement of users in pursuit of proper management-behaviour Improvementof the management procedures pro/cons: incentive provided by the client to achieve certain goals and values ​​of KPIsEvolution of Information System for the management of the service

7. Implementation The Green School project TECHNOLOGICAL INNOVATION SUSTAINABLE technological interventions and installations in the belief that even without significant resources available one can do much SOCIAL INNOVATION Approach to new technologies and new forms of organization in which students/teachers - not merely play a passive role, but are ready to participate actively in the evolution of the whole building and it’s facilities, also through the use of network , and all the innovations in communications, in order to make technology a tool as functional as possible to the social aswellaseconomicdevelopment After awarding of the contract, contractors translated the bid specifications into GreenSchoolproject, which builds on the improvement of management procedures already established. It is proposed to initiate a transformation of school buildings through a combination ofTechnological Innovation and Social Innovation, to make schools more efficient and sustainable through a combination of innovative technologies, and active participation of citizens/users.

9. Social innovation Spreading the culture of energy saving andsustainability Participation for the improvement of energy performance in the school buildings • GOALS: Promoting the establishment of an Energy Team in each school. Using direct communication channels already present in the 2 generation. Finding and training Energy Officer of the Campus. Through the Energy Officer of the Campus, create formation of new Energy Team in the schools. Training continues in the Energy Teams TOOLS: Economic bonuses to be distributed to schools according to participation. Competition for the distribution of bonuses Smart metering as a liaison between the user and technology. Ability to measure at any time the level of consumption and thus the efficiency of the actions and behavior New ECO web portal: a tool for communication, training and sharing dedicated to all citizens or users and to the diffusion of the project-model

10. Establishment of an Energy Team • Promoting the establishment of an Energy Team in the schools. Using direct communication channels already present in the 2 generation. • Finding and training Energy Officer of the school. Through the Energy Officer of the school, create formation of new Energy Team in the schools, coordinated by a teacher and composed by the faculty, students and staff . • Education continue in the Energy Team andthrough involvement of increasingly large segments of the school population EO 5 EO 3 EO 4 EO 6 EO 2 EO 1

11. Competition for the allocation of economic bonus to be distributed to schools

12. Smart metering, connecting element between the user and technology Users can check at any moment the effect of actions taken to save The facilities manager has a tool to rapidly assess corrective and preventive action

13. Web portal • The functions of the new portal: • Managing maintenance operations, logistics (local employment plan), technical documentation and certifications (functions already handled by the old portal) • Energy management: real-time visualization consumption (Smart Metering), management of the Middle State Energy of the Patrimony • Managing the competition and distribution of bonus/price • Presentation of projects implemented by each institution in the field of energy saving • Projects carried out by comparison with other institutions, both nationally and internationally (foreseen a section in English)

14. The results • OBTAINED: • Involvement of the users in the management of assets with a specific Communication plan; constitution of the first Energy Team • Rationalizingprocedures and reducingoperatingcosts with an economy, alreadydetermined by the institution with an lowestbid of € 840,000 / year • Starting a redevelopment technology already underway aimed at a reduction of 12% in heat consumption and 1% in electricity consumption (Qt) • EXPECTED: • Further8% reduction in energyconsumptiondue to the involvementofusers(Qs) • Increasedenvironmentalawarenessamongstudentsaboutsustainability and multiplyingeffectgivenby the project due to the educational / pedagogical contribution

15. The results

16. Objectives, developments, replicability of the model Goals for 2016 (end of contract): 20% reducedheatconsumption 20% reducedemissions Possible further goal(with economies reinvestment)20% more renewableenergysources • The savings in management can improve the condition of the school buildings in terms of: • Quality of space • Safety • Furtherriductionofenergyconsumption • The model, althoughobtainedthrough an evolutionaryprocess, lendsitself 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 schoolbuildings, wheresimilarsavings to those of the Province can be obtained

17. The schools A thoroughly examination of the buildings have let to this action plan for technological interventions to be implemented at the schools.

18. Twoexamples on interventions Technological Innovation – Pilot Project 1 & 2 Actions that are currently being implemented

19. Expectedbenefits Technological Innovation – Pilot Project 1 «the school A. Palladio» Expected benefits by optimization of the existing plant and installation of a photo-voltaic panel system Primary energy consumption Carbon dioxide CO2 Nitrogen oxides NOx Initial target Finaltarget

20. Expectedbenefits Technological Innovation – Pilot Project 2 «the school E. Fermi» Expected benefits changing from oil to methane gas plant and installing a geothermal plant Carbon dioxide CO2 Primary energy consumption Nitrogen oxides NOx Initial target Finaltarget

21. The Province of Trevisoheadquartes Energy and cool/heat to 100,000 m³ of buildings using no more fossil fuels than 14 single-family houses (4,458 m³) Every time we turn up the heat, the level of CO₂ emissionsincreases. Becauseheatingisoftenproducedusingfossilfuelssuchascoal and oil. And the production processemits CO₂. The more we can reduce ourdependence on fossilfuels, the more we can reduce CO₂emissions. 1050m² photovoltaicpanels (200kW) and 1 biofuelplant (360kW) When The Province of Treviso decided to allocate and renovate an existing building complex, itwasagreedthat alternative sources of energywould be utilized. 1050 m² photovoltaicpanelswereinstalled on a field, whichtogether with the biofuelplantswould be used to heat and produce energy to the buildings. And to minimizeheatloss, a building automationsystem (BAS) wasinstalled. Cooling/heating from fossilfuelsequal to that of 14 single-family houses The solutionaboveprovidesenoughcooling/heating and energy for the 100,000 m³ building complex, that the amount of fossilfuelsactuallyusedis no more thanittakes to cool/heat 14 single-family houses. The CO₂ accounts show some impressive results: The buildingsemitsapproximately 807 tonsless CO₂ pr. year.

22. The Province of Trevisoheadquartes Heating and energy using RES = 807 tons/y less emission of CO2 Fuel consumption and emissions: • Consumption of wood chips: approx. 5000 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 - photovoltaicopanels Wood chips
