The technological innovation serving the Venetian villas and the architectural heritage: the SWindErgy wind energy production system.

The aim of this article is to introduce SWindErgy, an innovative system among the available technological systems of energy production. The following topics will be examined: the methodological approach to the development of the idea, a critical analysis of the apparatus (costs, benefits, feasibility), possible future developments and various application possibilities. The system appears as a flat and elongated stem, anchored to the ground, devoid of rotating parts, reversible and therefore removable with low environmental impact. Only with light gusts of wind, the system begins to move, converting these small oscillations into electrical energy, through permanent magnet generators. A mathematical model was developed, allowing to carry out a series of sensitivity analyses to evaluate the parameters that can most influence the functioning and efficiency of the system. The purpose was to identify possible areas of intervention to increase the overall efficiency of the system. Through this model it was also possible to make estimates of productibility in various Italian locations. The research has also examined a technical-economic evaluation about the standard production of 20 elements and realized a study of costs/benefits ratio, as well as developed a prudential estimate of the market shares and of the sales of the SWindErgy system. The project has already been proposed for the competition of the Venetian Villas Regional Institute and was born from the need to operate on contexts like the villas, subject to constraints, with conservative interventions of the property and with advanced technological integration, as a barrier and safeguard from degradation and/or environmental deterioration.
