The Verona City Council has installed on the roof of their buildings over 6 MW of PV. Arenzano for municipal building code requires a minimum production of 1,500 kWh for PV building unit, double if an air conditioner is. Examples of municipalities that have focused on the solar report ‘Renewable Municipalities’.
the PV can do much for the Italian municipalities, helping to cut bills and improve balance sheets. And local authorities can do a lot for the transition to clean energy, since it put solar on the roof of schools, sports arenas and other public buildings also has a strong educational value and that municipalities have a powerful tool in promoting municipal building regulations. Italian municipalities that they’ve noticed are many, as it turns out in the latest report by consulting the chapter Renewable Municipalities Legambiente.
868 are in fact – it says – municipalities that have installed solar photovoltaic panels on the roofs of their building structures, to reduce the energy costs of public buildings like schools, administrative offices, libraries, etc. At the beginning of 2015 were already 12 municipalities in more than last year, for a total installed capacity of 96.1 MW.
Municipalities with more PV on their buildings
Among the local authorities with the most installed capacity of joint structures are the City of Verona with 6.1 MW of installed power distributed among the roofs of schools and municipal swimming pools, respectively 991.78 and 209.48 kW. Another solar photovoltaic 999.08 kW was installed on the roof of the Stadio Bentegodi, as well as a 3.7-MW plant installed on the roofs of the eleven halls of the Consorzio Zai, formed by the City of Verona, Verona Province and the Chamber of Business. This facility among the largest on public roofs, consists of over 48 thousand modules which cover 37,300 square meters of the roof, on a surface of 71,440. The energy produced covering the needs of 1,240 families and corresponds to a reduction of carbon dioxide released into the atmosphere of 1,850 tons.
In second place we find the City of Cisano Bergamasco (BG) with 2.9 MW, followed in third place by the City of Bologna with 1.9 MW distributed on 27 PV systems, 21 of which with a capacity of 1.3 MW made in 2012 on the roofs of municipal schools. All interventions are also mapped to a static paper downloaded from the website of the City.
A boost to the spread of photovoltaics (solar and thermal) is fundamental that it is integration in buildings. They are 979 municipalities that have introduced within the Municipal Building Regulations required the installation of photovoltaic solar panels. The national parameters for the electrical needs of the building include the installation of renewable sources in proportion to the size of the building.
In Emilia Romagna again we have anticipated the national requirements of the Decree. 28/2011 with requirements that add even more ambitious requirement of 1 kWp per unit of additional minimum requirements to achieve in terms of installed capacity relative to the surface of the house.
There are many municipalities that evidently wish to push the spread of PV thanks to the Building Regulations. For example, in 6 municipalities will require the installation of solar photovoltaic for more than 1 kWp: Collesalvetti (LI) and Dairago (MI) 1.2 kW, in Zogno (BG) and Sulbiate (MB) 1.5 kW and Lanuvio (RM) 2 kW. Offida (AP) demand rises to 3 kWp per unit. Arenzano (GE) is a required minimum annual production of 1,500 kWh per building unit, doubled if the building is equipped with air conditioning for the summer.
Photovoltaic windows obligatory
Finally in terms of innovation is interesting what happens in the municipalities of Cesnate con Bernate (CO), Ordona (FG) and Montemurro (PZ) which is promoted the use of solar cells for the darkening of the windows in new buildings and renovations.
A limit constraints historical landscape
Finally it should be noted how in Bagno a Ripoli (FI) in October 2014 removed the limitation for the realization of solar thermal and / or photovoltaic panels on the roofs of buildings of special historic value and scenic and historic cultural. The resolution was created in order to increase the useful surfaces for photovoltaic panels and offer new possibilities for installation of systems of sustainable energy production subject to the requirements descendants from any environmental constraints, linked to respect for energy, and the Plan of address territorial (Pit) with value of the landscape plan, currently under safeguard.
