The present document was elaborated in the frame of the ‘MANERGY - Paving the way for
self-sufficient regional energy supply based on sustainable energy concepts and
renewable energy sources’ project, financed by the CENTRAL EUROPE programme of
the European Union.
Duration of the project: 1 May 2011 – 30 Apr 2014.
Output number: 3.3.4
The
project
The Kyoto protocol, the EU 2020 Strategy and several further commitments force the states of CE to
rationalize their energy consumption and reduce the fossil energy sources in their energy mix in favour of
renewables. MANERGY assists the CE area in achieving these goals by setting its general objective:
supporting the responsible use of the environmental potentials of CE by promoting sustainable approaches
to environment friendly energy source management, including an increase in renewable energy use and
significant reduction in energy consumption and CO2 emissions. As urban areas represent more than two
thirds of the energy consumption of the EU, the role of local authorities in energy saving is significant.
This tendency is fostered by the central governments in all countries, urging the public authorities to cut their
expenses by rationalizing their overhead costs. MANERGY partners aid local authorities to answer this
challenge and pave the way for the self-sufficient regional energy supply. Therefore the project has set the
specific objectives of elaborating innovative transnational method for local authorities to raise their energy
efficiency and increase the use of renewable sources; setting up transnational network to assist the
implementation of this process; transferring the elaborated tools for enhanced renewable energy use to
regional/local levels and support preparations of practical energy applications; providing a clear picture for
decision makers and transferring the energy concepts to regional/national policies; raising awareness on the
benefits of renewable energy supply and energy efficiency. Based on the similarities in the energy supply of
the partners, transnational cooperation offers the opportunity for direct exchange on the needs and future
aspirations related to these topics. In the CE area currently there is no such official transnational level forum
which would deal with these issues. The regions and local authorities are mostly the ones who implement
the different approaches of energy use, on the other hand they in themselves separately are not strong
stakeholders to have their voice heard in order to shape the system. By its transnational approach the
project will transfer its results to other CE cities and also support the forming EU’s energy policy. Besides,
transnational cooperation gives that chance for local authorities - which would not have otherwise the
possibility to access to a wide range of know-how - to improve their energy management by benefiting from
best practices of other CE countries. MANERGY involves institutions with the competence and capacity to
the specific objectives. The development agencies and the province have the capacity to develop and
implement local/regional policies to support the efficient public energy consumption and increased use of
renewables. The scientific and expert institutions have expertise’s in the research and evaluation of the use
of the regenerative energy sources, in these cases the implementation of the elaborated tools will be
ensured also by associated institutions. WP1 ensures the smooth cooperation and manage all project
activities; WP2 spreads the results at 3 interregional conferences, 2 EU events, 1 website, 2 brochures, 6
newsletters and several media appearances. In WP3 energy consumption of local authorities and the
renewable energy sources is mapped and supported by a digital map. Regional energy concepts will match
the demand and supply optimally, a comparative study and a transnational tool of defining energy concepts
will be worked out and ‘illustrated’ by a case study booklet. To amend the organisational structure of
implementing the concepts, WP4 analyses the requirements of setting up energy agencies that will be
compared in a transnational study. Partners also deliver business plans for the EAs. WP5 will test the
transnational tool and implement regional concepts in practice by local concepts and action plans.

Sile (river)
From Wikipedia, the free encyclopedia.
The Sile (Venetian: Sil) is a 95 km river in northern Italy. Its resurgent springs are near Vedelago (Province
of Treviso) and it flows into the Venetian lagoon at the port of Piave Vecchia. It meets its tributary the
Botteniga, or Cagnan, at Treviso.
Dante’s Cunizza da Romano prophesies the fate of Rizzardo da Camino—he was apparently murdered at a
game of chess—, locating it at this confluence:[1] e dove Sile e Cagnan s'accompagna, tal signoreggia e va
con la testa alta, che già per lui carpir si fa la ragna.
—Dante Alighieri, Paradiso, IX.49-51
(And where the Cagnan and the Sile meet, there’s one in power who goes with head held high: the net to
catch him is already made.)

The plant was built between 1957 and 1960 on the Piave River, whose total catchment area is
approximately 1474 km² wide, and feeds an important system of hydroelectric plants (see separate detailed
scheme) with a total installed power of approx. 650 MW and a total yearly production of approx. 2300 GWh.
Inside there are two production units (Francis turbines) of the total power of 30 MW, that can produce energy
for the average annual needs to approximately 50.000 households. At the end of the production cycle a
spillway over 1 km long returns the waters used by entering them directly into the stilling basin of the canal
Brentella Pederobba, from which begins a complex system derivations to a multiple use.

The electricity produced by the alternator is sent to a static machine, transformer, which raises the voltage
from 10.000 volts to 130.000 volts for transmission lines.
The transformation allows the transport of the electricity and minimize losses and costs.
The energy produced is placed on the network to 130kV power station adjacent to the station, which is
connected to the national grid through a number of two power lines.
In this station is also a stall of transformation from 130 to 20 kV which feeds the primary cabin distribution.

I.S.I.S.S “GIUSEPPE VERDI” – GREEN SCHOOLS
Introduction
The study carried out in Treviso in the framework of Manergy - WP3 activities for drafting of the Regional
Energy Concept, has shown that small investments, with a relatively short payback time, are probably the
most effective way to promote a widespread use of energy saving and renewable sources technology in
public owned buildings.
A short payback time enables to perform a relevant number of small investments in the framework of an
“energy performance” contract, or EPC, with no need of initial investments, as initial investments are paid by
the contractor, and paid back through the savings achieved in the contract duration time. In this way a large
number of buildings and consequently of users can take advantage of the technological innovation.
In the case of school buildings there are two more advantages. The first is the possibility of involving
frequent users (students, teachers, headmasters) in activating the correct use of buildings and facilities, with
a potential additional savings. The second is the educational function carried out in this way, and the
consequent multiplication effect through virtuous behaviors that students themselves will take in the future.
In this context, the Province of Treviso has developed an interesting experience in management of its
property portfolio, mainly consisting in buildings for the Higher Secondary Education. This experience aims
to achieve significant savings in two different but concurrent ways:


Through a set of technological actions, based on high efficiency heat production and on renewable
energy sources;
Through a communication plan for the active involvement of users in the correct and responsible
utilization of buildings and systems.

Context description
The Province of Treviso is an administrative entity of intermediate level between Regions and Municipalities.
It covers a territory of 2.476 sqKm with a population of 889.000 inhabitants, and is in charge of specific tasks
related to the management of the inter-municipalities territory and of the whole province territory. In
cooperation with municipalities, the Province promotes, coordinates and implements specific actions in
different sectors such as economic, productive, commercial and tourism, as well as social, cultural and
sports.
For management of its property portfolio, consisting predominantly of buildings for the Higher Secondary
Education, the Province of Treviso has adopted for years as main tool the “Global Service” outsourcing
formula. The recent award of a new contract for the five years 2011 - 2016, fits in this context.
The actual consistence of the real estate portfolio is shown in the table below:

The buildings are located in 13 different municipalities belonging to the territory of the province of Treviso.
The new experience suggests strong innovation elements, such as an emphasis on the role that the user
can actively play in the management process of public buildings, and a performance contractual formula for
energy management (EPC – Energy Performance Contract) which will improve energy efficiency through a
number of major technological investments already fixed in the contract awarding after public competitive
tendering.
The project that led to the new service has been initially identified as "third generation Global Service" or "GS
3.0" to emphasize the continuity with a Facility Management outsourcing experience started over twelve
years ago, has been recently renamed as “Green Facility Management”. The word “Green” in this context
includes not only the aims of energy efficiency, which are still present in a very large number of facility
management contracts, but includes particularly the ways through which these aims are pursued.
The objectives in this case are certainly wider than those of a simple maintenance or energy performance
contract, and are certainly higher than those emerging from the mere energy balances. We can summarize
the objectives of this project of Green Facility Management for a School Buildings portfolio in the following
five points:
1. Reduce energy consumption and environmental impact;
2. Stimulate energy production through renewable sources;
3. Operate only through small investments;
4. Create a more livable and friendly school environment;
5. Increase teaching and educational effectiveness.
The first two objectives are essential to achieve economical sustainability, exploiting all the opportunities
arising from a rationalization in the management of energy sources. The containment of investments is
another essential requirement, especially in the context of a short period contract, which does not allow
enough time to cover larger scale investments.
The next two goals allow, through the involvement of people and increasing awareness, an important
contribution in limiting energy consumption, and improve specific elements such as absenteeism,
Manergy_Study tour fact sheets
17
productivity, school performance, just to name a few. Besides, they play an important educational role in
terms of inducing awareness on energy and environmental sustainability in young people.
Technological innovation and social innovation in GFM
In GFM traditional technological tools for energy saving are combined with elements of technological and
social innovation1. Elements of innovation can be an added value in a GFM project, helping to meet the
earlier mentioned objectives with a smaller or at least a different effort than in a traditional approach.
The goal is to rethink the role of maintenance in facility management, considering the active management of
the building by people who live there and not giving up, then, the contribution that this very important part of
people can give, both in a positive and negative sense (the latter when users do not cooperate or worse they
are a source of waste and losses) for the optimal use of available resources.
ICT and Smart Metering play a basic role in this context, as they are the means through which people
involved at various levels in the building management process are made aware of the results produced by
their efforts. Users (students and teachers in the case of school buildings)are obviously considered among
them, as in the context of GFM they are actively involved in the building management process, together with
Owners and Space Managers (Local Authorities and Headmasters in the case of school buildings).
Carrying out the GFM project
Figure 1: GFM project - phases and results of technological innovation and social innovation
in figure 1the 5 steps of a typical GFM project are shown. Along each step the expected results from the two
different elements of innovation are put into evidence.
The following steps are represented:
1. Define, in which the project objectives are developed , defined a set and pursued a process of
development of your needs. In this phase should be made an effort to identify the elements that will be
measured during the service in order to structure the paths of improvement and optimization.
2. Design, in which the private partner is identified through public procurement procedure, the technical and
commercial contract is signed, the project team of client and supplier(joint committee) is appointed, and its
operational
modalities
to
manage
the
subsequent
stages
are
set
down.
3. Implementation. In this step all the transformations assumed by the customer in the phase of define and
by the supplier during the design phase are carried out.
At present the GFM Treviso project is at the beginning of the implementation phase.
1Social innovation
is about new ideas that work to address pressing unmet needs. We simply describe it as innovations
that are both social in their ends and in their means. Social innovations are new ideas (products, services and models)
that simultaneously meet social needs (more effectively that alternatives) and create new social relationships or
collaborations (Open Book of Social Innovation, Murray, Calulier-Grice and Mulgan, March 2010)
Manergy_Study tour fact sheets

The transformations include:
a. Technological improvements of existing heating systems;
b. Installation of new systems;
c. Implementation of computer systems;
d. Remote control systems and automation (smart metering);
e. Creation of a service agreement between owners and users;
f. Implementing a communication plan;
g. Training
Installation of smart metering systems at this stage is the basis for the whole process improvement and
optimization. The smart metering systems will be applied both to thermal and electrical energy consumption
measurement.
The next steps are:
4. Consolidation, necessary step in any change management process, as is indeed the GFM, arrives after
the great turbulence flow from the preceding stage where they have been triggered all the changes, with the
purpose of consolidating the processes and results. Savings achieved in previous periods and habits have
now become part of daily lifestyles, and you can measure the benefits.
5. Going, when the innovation process has been completed, and new goals can be set.
In the same fig. 1 savings achievable through the application GFM are shown, and a distinction between
different contributions of technological and social innovation is made. The two effects Qt (technological) and
Qs (social) are easily measurable, provided they are known, as defined in the Define phase. The parameters
to be measured are typically power consumption, heat, water, waste products.
How can the ongoing project and Manergy positively affect each other?
The GFM Treviso project looks to fit properly in the framework of Manergy, and both projects could positively
affect each other.
Specifically, GFM can help to demonstrate that the achievement of energy efficiency in a local community
does not necessarily require significant investment.
On the other hand, Manergy can contribute, within the communication plan of GFM to schools, to create
consumer awareness that any action taken by the single individual or by a single community of users
(school) can provide an important result towards energy self-sufficiency of a local community.

THE BORTOLOMIOL PROJECT FOR ORGANIC PRODUCTION
Altre foto
From their sense of responsibility as a leading producer of Prosecco Superiore and also fruit of a project for
the creation of sustainable agriculture, Bortolomiol is experimenting with a new approach to growing –
organic agriculture – in their own vineyards in the heart of Valdobbiadene. This is because they understand
that the land must be protected so as to be passed on to future generations in the best possible
health.
Carlo Petrini (founder of Slow Food) explains that “Our food should be good, clean and right. Full of flavor,
not damaging to the environment and not produced by over exploitation of either the farmers or the land”.
The concept of Clean is what guides the Bortolomiol winery in their organic production project situated in the
two hectares of vineyard they tend inside the Parco della Filandetta.
The history of the silk mills (filande) and wine production was closely intertwined throughout the last century.
Today the smallest silk mill in town, inside the Parco della Filandetta, has been lovingly restored and made
into a tasting room which honors the women who lived and worked so hard there.
Manergy_Study tour fact sheets

Bortolomiol is dedicated to uniting their commitment to honoring this important part of local history with a
project for sustainable agriculture which will safeguard the rural heritage of the area for the future.
Wendell Berry, an American literary figure, cultural commentator and recipient of the National Humanities
Medal, wrote that by sensitizing consumers you make them responsible and empower them to question the
food industry and think about the future of nature itself, two concepts that are closely linked. In his words
“We are all, by proxy, farmers and so we must carefully consider the kind of agriculture that we give our
proxy to”.
An understanding of this common responsibility for the land is what drives Bortolomiol in their project for
organic, sustainable and low-impact cultivation. A project which is being piloted at home but is soon to be
shared with all the growers who work with this pioneering winery.
OUR HISTORY AND PASSION
By Giuliana Bortolomiol
The family-owned agricultural company is run entirely by Guiliana Bortolomiol who looks after the vineyards
with passion and dedication. The oldest vines date back to 1950 while the most recent were planted in 1997
and 2005. Before 1997 her father Giuliano had full responsibility for looking after the vineyards.
“I started working for the company in 1997. That was the year we expanded the vineyard with the first new
planting. At that time my father and I agreed to look for new treatment products that would have a lower
impact on the environment, and this was the beginning of our work towards sustainable cultivation. Since
2001 I’ve continued this work alone, always striving to find cultivation methods that respect the vines, the
earth and the surrounding environment. This is because I’m convinced the earth provides better fruits if we
have respect for it and respect means looking after it using low-impact, fully natural products and plants. The
result is not only do we get better fruit but we also produce benefits for our own wellbeing.
In 2008 I began a program of organic cultivation based on the expertise of Giovanni Pascarella and with the
full support of Elvira and Gianfranco Zanon. After these first three years I’m really very satisfied with the
quality and more than ever convinced I made the right choice both for the vines and for our own health.
THE PRINCIPLES OF ORGANIC VINEYARD CULTIVATION
ITALIANO ENGLISH
By Giovanni Pascarella
Organic cultivation means adopting a series of ecologically sound agricultural practices which avoid harmful
side effects and reduce the use of synthetic chemical products so as to improve the health of the
environment and human wellbeing. This is a method of cultivation which not only impacts vine health by
using Bordeaux mixture as a pesticide but governs the choice of training system, pruning, soil and inter-vine
management, weed control, foliage management and everything else right up to harvest. The objective of
organic cultivation is to arrive at a global production process that optimizes production quality while
protecting the environment and improving human wellbeing.
This strict production process requires constant attention in the vineyard to monitor the natural cycle of the
vines and the development of any diseases or other problems. All of these factors are then carefully
considered before any decision to intervene is taken as this is the only way to guarantee truly organic
cultivation, or ius naturae, of the vineyard.
THE NATURAL IUS NATURAE
By Gianfranco Zanon
IUS NATURAE, our new Valdobbiadene Prosecco Superiore Brut made from organically grown grapes, is
the natural consequence of the production philosophy of the Bortolomiol family who have always been keen
to practice both sustainable and environmentally respectful winegrowing.
Here their passion for the values of nature reaches new heights. During harvest two days are set aside
purely for harvesting these grapes so as to guarantee absolute control over their quality and ripeness.
The mousse is fine and persistent and the pale straw yellow color indicates the wine has great energy. An
energy that we find both on the nose with its deep austere bouquet of fragrant fruity, flowery and mineral
notes of acacia honey and almond flower as well as in the mouth. Here the sweetness is controlled and its
zest, combined with a lovely freshness, brings a solid, vigorous and lasting flavor.

Valdobbiadene is characterized by an irregular landscape of hills, with lands entirely covered by vines. In
harmony with this context The “Cantina produttori Vald’Oca” wished to insert a new building next to the
existing factory. The idea was to construct a building with focus on the environment, creating a space to
promote the production for sale and tasting of wines products of the Vald’Oca wine production. The project
began in September 2006 and the new building was taken into use in July 2011.
The building has a surface of 3390 square meters, of which a footprint of 490 square meters of retail space
and exhibition space on two levels above ground and underground storage. On the ground floor the building
has spaces for the sale and display of products, while the first floor has a tasting room designed to
accommodate indoor and outdoor events, wine and culture, and an administrative area.
The building is provided with energy saving technologies and renewable energy sources which enable the
building to be almost energy self-sufficient: The photovoltaic membrane in amorphous silicon placed on the
roof is producing 17 kW, the geothermal system with reversible heat pump, the external insulation and the
selective glazing windows. The project is also distinguished by the participation of local workers who used
mostly recycled and certified materials.
The main façade is covered by a surface of 620 sq.m. perforated aluminum panels supported by a metallic
frame. The holes on the panels design a composition that looks like the bubbles in a prosecco glass. An
RGB illumination system is placed behind the cover: during the night the façade becomes a luminous sign
that changes color to announce special event organized by the vald’Oca company.

Novalis, Steiner
The Cooperative San Michele was founded in 1987 by a group of scholars of anthroposophy, the agricultural
company San Michele in Manzana of Conegliano (TV) is made up of about 65 hectares, cultivated with the
biodynamic method. There, vegetables, milk and eggs are produced. Besides the employees, there are
numerous seasonal workers and interns that collaborate to learn and perfect the techniques of biodynamic
farming. The elevated interest demonstrated by the pupils during frequent visits, has convinced the
managers to expand its vocation in “farming didactic”, as well as the meeting place for alumni, students and
families.
The school
The Steiner school in San Vendemiano has been designed and built, accompanied with great attention to its
architectural shapes, colors and substances of building materials, as to all the technical solutions that
contribute to the health of the building as well as the health of the users of the buildings.
Some important technical aspects.
The structural parts, except the roof, are concrete specially produced for this construction and consists
purely of marl without the addition of other inert substances and chemical compounds normally present in
commercial products.
The bricks used are also certified and microporous with wood flour.
The plasters are natural hydraulic lime and finish silicate based purely natural origin.
The roof is made of wood and the coating of zinc-titanium cover. Beams and planks have achieved a fire
resistance of 120 minutes with the impregnation of a solution to the boron salts certified, produced in
England. The insulation package is constituted by a mattress in the rock wool of basalt origin (thickness 20
cm), and a double chamber ventilation.
The insulation of the walls is constituted by an outer coat of cork (thickness 15 cm) and an inner lining of
rock wool of basalt origin (thickness 2 cm) enclosed between the septum of concrete (thickness 25 cm) and
an internal counter microporous brick (12 cm thick).
The electrical system is shielded with a paint carbon earthed for the dispersion of the electric fields.
The heating / cooling system is powered by an exchange of geothermal heat and consists of radiating bodies
placed in the walls of classrooms and other areas in the floor of the school.
