L’ objective is the transformation of the market by introducing new centrifugal pumps for increased efficiency – Energy+ pumps – for much more efficient circulation of heating than already used today. A new age of technology of pumps with the use of commutation electronics is available and allows a reduction of consumption of approximately 60% to be obtained.

The FEM with the collaboration of different partners implemented and foresaw in the medium term initiatives included in the project named “Parco dell’Energia” (ReXergy) divided in different subsets and which has the theme of sustainable energy as leitmotif. The actions and interventions programmed have the task to promote:
1) The spread of the use of sustainable energy resources (WP1);
2) Energy saving and energy efficiency of facilities and of buildings (WP2);
3) The creation of a observatory for the sustainable energy dedicated to agricultural enterprises (WP3).
The project is based on of three level of action: pointed research, to widen scientific knowledge in some sectors (anaerobic digestion; bio ethanol; cell functioning with fuel) technological transfer of innovations gauging the interventions to the specificities of local entrepreneurial situations; moments of training and spread.

The only power source of the system is the sun power and the only power transformation involved is that needed to make positioning and focusing system working. The power transferred on the object is given by a geometrical reflection of incident sunlight.
The system works according to the principle of the incident ray of light being reflected on a level surface; the sunlight is reflected from outside into the tunnel, producing then a natural beam which completely eliminates sudden changes in lighting.
A photovoltaic cells battery transform a small amount of energy provided by the sun in electricity, that drives a hydraulic power centre and an electronic device in charge of focusing and moving the reflecting surface.

L’ objective is the transformation of the market by introducing new centrifugal pumps for increased efficiency – Energy+ pumps – for much more efficient circulation of heating than already used today. A new age of technology of pumps with the use of commutation electronics is available and allows a reduction of consumption of approximately 60% to be obtained.

The intervention, as a whole, aims to adopt the European resolutions for an enviro-sustainable development, promoting the practice of a building culture aiming to protect the environment, the compatibility of the energy cycles of the eco-system and implementing the principles of the bio ecological technology.
The general target is, thus, to promote and spread bio architecture as a new environmental approach to the living problem, since it reduces the environmental impact and the energy costs of the construction sector.
The specific goal is to check the problems connected to the costs involved in application of such techniques, in the refurbished and in the new building, by analysing the results obtained from the point of view of the environmental qualities achieved. The school building, part of the EDERA project, is particularly fit for functional re-use according to the standards of bio-ecological architecture, because of it’s specific logistic position in good environmental quality area, near to the Stura stream and near some facilities, such as, the municipal sports field, some playgrounds and next to the local train station. In the area there, also, some public structures used for exhibitions (Expo Vallestura) and a distance-learning centre (Telecentro).
This school structure has always been, for the local community, an important reference point since it is a public space where students, teachers and families meet dedicated to develop the children’s knowledge and expressivity.
The re-qualification intervention has been immediately supported and shared by the residents, and seen as the possibility to regain possession of a shared public area re-evaluated by the bio-ecological renewal carried out.
With the present project, the Municipality of Rossiglione has been recognised as “excellent case” among the Liguria Local Authorities in the field of environmental management and received a special mention at the award ” Cities for sustainable construction”, aimed to the public administrations that have carried out works, rules and actions for sustainable constructions, assigned by Friuli Venezia Giulia Region during the BIO CASA event at the exposition centre in Trieste, with the sponsorship of ITACA, Institute for the Transparency, Updating and Certification of the contracts and of the Conference of the Region Governors.
ITACA, to which the project Liguria Region belongs, has developed a Protocol approved by the Conference of the Region Governors for energy and environmental certification of the buildings. It consists of a list of requirements and needs for the environmental compatibility, by means of which it has been possible to carry out checks on the entire school compound, object of the experimentation.
In the costs/benefits evaluation of the pilot project, the procedure of Life Cycle Impact Assessment has been experimentally implemented to evaluate the impacts and the avoided external costs in the building /refurbishing and in the operating phases of the school building.
