Wooden eco–school to be built in leasing
By the end of May will start construction works of a new didactic pole of low energy consumption, designed by Avventura Urbana for the Region of Turin, Italy.
A preschool of 3000 Esq inspired by the principles of bio-construction is going to be realized in the Vinovo region (to the South of Piedmont). The particularity of this small contract that hardly exceeds three millions Euro is the application of leaseback, so called leasing “In Construendo”.
The winner enterprises of the tender assure that this is the first operation of its kind in Piedmont. The members of the winner T.A.E. are the Secap enterprise of Turin, La Foca Latvija enterprise of Latvia that is specialized in wood construction, Tecnelit Impianti of Turin. The project is under the auspices of Avventura Urbana of Turin while Ing Operleasing is the financial partner.
The group has won the tender using the preliminary project of Municipality (elaborated in collaboration with the Agency of environment of Piedmont) proposing a number of improvements that would increase energy saving performance and reduce the terms of execution. Such improvements allowed to obtain additional points according to evaluation system, where approval criteria were based on the most economically advantageous offer (up to 35 points for the economical value, up to 40 for the technical value and 25 points for the terms of execution).
The meliorative proposal, says Matteo Robiglio, Avventura Urbana's shareholder, was implied in the energy performance improvements. “We have proved that it was possible to install a heat pump powered by photovoltaic panels instead of the methane powered condensation furnace that was planned initially”.
Green covering and photovoltaic panels on the roof
Energy saving and eco-sustainability start from the roof: a light green roof (10 cm of soil) is planned above the space destined to the service area (canteen, school hall and staffrooms), while above the classrooms there will be installed photovoltaic panels integrated in the covering for 130 Esq. “We've made possible a better performance of the wooden components gaining a crucial abatement of the execution terms”, concludes Robiglio.
Wood is the key-element. The choice has been made in favour of supporting walls with entire span reticular structure with 60-80 cm pitch. Wood is not visible in the rooms, except for connecting areas, while the classroom floors are in wood with heating serpentines underneath.
Construction works will start in May and will continue for 250 working days. Total covered area of 3.050 Esq is for two thirds dedicated to the classrooms and for one third to service and common spaces (canteen, theater, gym). It will be possible to host 250 children in the building.
Energy saving performance, obtained in part by insulation materials, is more than sufficient: 19.4 kWh/Esq per year.
