When you were looking for your perfect home in Florence, did you pay much (or any) attention to that sliding scale from “A4” to “G” that declared the energy efficiency of your future four walls? Perhaps you were more taken by the Tuscan countryside and smitten by the sunsets. I don’t blame you for favouring the view; I did too. But when you’ve lived here for a while and the money is seeping out the door in an ever-flowing current of bills, you take a second look at those long windows, which in the summer carry a welcome breeze through your citronella-scented home (those pesky mosquitoes!), but in the winter are wicked for blasting gusts of icy wind to where you’re wrapped in blankets lamenting the lack of insulation. Energy efficiency is still not a decisive element in the choices of homeowners in Italy, and it perhaps should be.
