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.

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 as well as economic development

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 Teams

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

TOOLS:

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

• 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 and through involvement of increasingly large segments of the school population

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

Page 13: “ Green  Schools” In the  Province of Treviso Antonio  Zonta Treviso

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)

Page 14: “ Green  Schools” In the  Province of Treviso Antonio  Zonta Treviso

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 contribution

OBTAINED:• Involvement of the users in the management of assets with a specific Communication plan; constitution

of the first Energy Team• Rationalizing procedures and reducing operating costs with an economy, already determined by the

institution with an lowest bid 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)

The results

Page 16: “ Green  Schools” In the  Province of Treviso Antonio  Zonta Treviso

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 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

Goals for 2016 (end of contract): 20% reduced heat consumption20% reduced emissions

Possible further goal(with economies reinvestment) 20% more renewable energy sources

The schools

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

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 CO₂ emissions.

1050 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. 1050 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)

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 - photovoltaico panels

Heating and energy using RES = 807 tons/y less emission of CO2
