OBJECTIVESSOLUTIONSImplementation

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.TECHNOLOGICAL INNOVATIONSUSTAINABLE technological interventions and installations in the belief that even without significant resources available one can do muchSOCIAL INNOVATIONApproach 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 its 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 as well as economic developmentThe Green School projectTechnological Innovations

Social innovation

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 TeamsEconomic bonuses to be distributed to schools according to participation. Competition for the distribution of bonusesSmart 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 behaviorNew ECO web portal: a tool for communication, training and sharing dedicated to all citizens or users and to the diffusion of the project-model

TOOLS:GOALS:Spreading the culture of energy saving and sustainabilityParticipation for the improvement of energy performance in the school buildings

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 and through involvement of increasingly large segments of the school populationCompetition for the allocation of economic bonus to be distributed to schools

Smart metering, connecting element between the user and technology

Users can check at any moment the effect of actions taken to saveThe facilities manager has a tool to rapidly assess corrective and preventive action

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 PatrimonyManaging the competition and distribution of bonus/pricePresentation of projects implemented by each institution in the field of energy savingProjects carried out by comparison with other institutions, both nationally and internationally (foreseen a section in English)

The results

EXPECTED:Further 8% reduction in energy consumption due to the involvement of users (Qs)Increased environmental awareness among students about sustainability and multiplying effect given by the project due to the educational / pedagogical contributionOBTAINED:Involvement of the users in the management of assets with a specific Communication plan; constitution of the first Energy TeamRationalizing procedures and reducing operating costs with an economy, already determined by the institution with an lowest bid of 840,000 / yearStarting a redevelopment technology already underway aimed at a reduction of 12% in heat consumption and 1% in electricity consumption (Qt)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 spaceSafetyFurther 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 obtainedGoals for 2016 (end of contract): 20% reduced heat consumption20% reduced emissionsPossible further goal(with economies reinvestment)20% more renewable energy sourcesThe schools

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

INSTITUTE Interventions for the exploitation of renewable energy sources Technological requalification interventions Interventions for the remote reading of energy carriers interventions on water consumption Construction of a solar PV system Creation of an air conditioning system to geothermal heat pump Construction of a cogeneration plant or traditional biomass Trasformation for operation with natural gas Replacement of boilers Remaking piping pipes in thermal power plant and substations Completion of the temperature control system Installation of thermostatic valves on radiators Interventions for the remote reading of consumption of solid fuel or gas Interventions for the remote reading of electricity consumption, inst. of equipment x-meterInstalling timed taps of hot and cold water terminals

Expected benefitsprimary energy savings and consequent reduction of CO emissions, as well as high energy performance (COP) can be achieved.20The Province of Treviso headquartes

Every time we turn up the heat, the level of CO emissions increases. Because heating is often produced using fossil fuels such as coal and oil. And the production process emits CO. The more we can reduce our dependence on fossil fuels, the more we can reduce CO emissions.1050 m 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. 1050 m 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 housesThe solution above provides enough cooling/heating and energy for the 100,000 m building complex, that the amount of fossil fuels actually used is no more than it takes to cool/heat 14 single-family houses. The CO accounts show some impressive results: The buildings emits approximately 807 tons less CO pr. year.Energy and cool/heat to 100,000 m of buildings using no more fossil fuels than 14 single-family houses (4,458 m)Some exampels of this una casa media italiana per 4 persone 110 m uguale a 297 m (la province in m sarebbe circa 336 case) 14 case uquale a 4.458 m consumo di metano. The photovoltaic panels reduce the emissions with 176,8 tons of CO - why does the Daikin reach 630 tons/y?? Together reduce emissions with 807 tons/y .The biofuel plant has 0 emissions of COThe metane gas emits 42,660 tons of COThe redution from fossil fuels leeds to a emissions of 134 tons of CO

Fuel consumption and emissions:

Consumption of wood chips: approx. 5000 m per year

Production ashes: approx. 110 m / year

Gas equivalent: approx. 300,000 m

Greenhouse gas CO2 equivalent: approx. 700 t / year

CO2 emissions to 5000 m 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 panelsHeating and energy using RES = 807 tons/y less emission of CO2Wood chips
