Still a short time left has Superbonus for those who want to rebuild the house from an energy consumption point of view, but live in one bound condominium where insulation interventions are not possible. In this situation, it is sufficient to only achieve the jump of two energy classes for your own apartment, but the same deadlines apply as for the villas, so it will be possible to take advantage of the deduction of 110% until the end of the year. that the 30% of the works.
When the coat can not be made
In general, those buildings where exterior insulation is not possible are all these built before 1945, as they are among the “historic” buildings. Even when the limitation of art is not present, there are generally restrictions at the municipal level that prevent intervention in order not to change the architectural design. Therefore, the law allows individual owners to get the maximum deduction by performing only “towed” interventions, ie all those who give directly to the eco-bonus. It is a mixture of non-invasive interventions and the result is always guaranteed when there is no central heating system.

How much do you save by changing the boiler
Replacing the boiler is in fact already in itself a great advantage, especially when starting from the energy class G, which is the lowest, where there are usually time-typical houses that have not been worked on in recent years. In fact, it is not uncommon in these situations to find boilers that are at least 15 years old. It is clear in this situation that being able to have the new boiler for free, thanks to the Superbonus, the intervention is definitely advantageous. It is possible to see the savings in terms of consumption that can be achieved with these operations, by taking advantage of the test developed by Enea, 4ECasa, which allows you to detect the level of your consumption compared to that in a recent building, with the same characteristics and in the same location, but built with efficiency criteria.
Air conditioning instead of gas
In a period building, it is difficult to hypothesize that it will be possible to replace the gas system with air conditioning, as the architectural decoration must be respected and the maximum savings by switching to the heat pump are achieved when the system can be combined with solar panels. When it is not possible to replace the boiler with air conditioning, you can still count on a 50% bonus to buy the latter, which, if used well, still reduces the use of gas. You can then take advantage of this deduction to also have the mobile bonus.
New shutters and building automation
Installation of new blackout closures, on the other hand, is part of the Super Bonus, as it is an intervention that usually benefits from the eco-bonus. However, by utilizing the shutters and leaving the house in the shade during the day, you can, according to Enea data, save up to 25% on the use of electricity for cooling. Another of the interventions that help pass the class is the installation of the systems building automationbones all those that allow remote control of the implants and their programming.

How to make the calculations for Superbonus
To have the Superbonus until the end of the year, at least 30% of the total intervention must be completed by September. However, the count includes all the work that is intended to be performed, not just those for which the Superbonus is requested. So if the idea is to move forward with an overall restructuring, it is worthwhile to start all the interventions immediately.
