There is a date that, without making any noise, risks slipping into the daily lives of millions of Italians. May 2026. By that month, Italy will have to implement the European directive on green homes, a regulation that talks about buildings and energy consumption, but above all about how we live in our homes. It’s not a question for professionals: it concerns city condominiums, provincial villas, homes inherited from grandparents and those we imagine buying one day.
The deadline set by the European Union is 29 May 2026, the deadline by which all member states will have to formally implement the new Energy Performance of Buildings Directive, known as the Green Homes Directive.
The directive was born within the European path towards climate neutrality by 2050, an ambitious objective that also, and perhaps above all, passes beyond the walls of the home. Buildings consume enormous amounts of energy and have a significant impact on emissions. This is why Europe has decided to intervene precisely where change can have a concrete impact: in public and private homes and buildings.
For Italy the bill is not light. Estimates speak of around 85 billion euros by 2030 for energy redevelopment alone. But alongside the costs there are also the positive effects: a construction sector that is getting back on track, potentially lower bills, more livable cities and an economic turnaround which, according to experts, could reach 280 billion euros considering the related industries.
What “Green Homes” really are and why they concern us all
When we talk about green homes we don’t mean a “luxury” or hyper-technological home. The idea is much simpler and, at the same time, revolutionary: houses that consume less energy, heat and cool better, exploit renewable sources and offer healthier environments.
The European Union has put down on paper a figure that says it all: over half of gas consumption is linked to buildings. Reducing these consumptions means being less dependent on imports, spending less and polluting less. This is why the directive does not only look at the climate, but also at energy security and quality of life.
What will change
The directive does not impose immediate wholesale restructuring, but outlines a gradual path. Homes will have to consume less and less energy, with intermediate objectives already set for 2030 and 2035. The most inefficient buildings will be the first to have to change pace, while new buildings will have to be built with very high standards, until they reach zero emissions.
Another important piece concerns the sun. Europe is pushing for roofs to become allies of the energy transition, with increasingly widespread solar systems, especially in new buildings. It’s not just an environmental issue: producing energy where you consume it means reducing waste and costs.
The future of heating: goodbye to boilers as we know them
There is a point that affects many families closely: heating. The directive marks a clear change of direction. Incentives for fossil fuel boilers are disappearing and the horizon is clear: heat pumps, solar thermal and low-emission systems will become the norm. Not tomorrow morning, but within a few years yes.
This means that those who renovate today or in the next few years will have to start looking beyond gas, thinking about more sustainable and, over time, even more convenient solutions.
There is an aspect of the directive that often goes into the background, but which says a lot about the change in mentality underway. We are not just talking about numbers and kilowatts, but also about the quality of internal environments. Natural light, ventilation, solar shading are not aesthetic details: they affect comfort, health and even mood.
According to experts, making better use of daylight can significantly reduce lighting consumption. The external screens, then, help defend against the increasingly intense summer heat, without having to have air conditioners turned on all day. In other words, smarter and more livable homes, not just more efficient.
How much it will cost us and what we might gain from it
There is no point in beating around the bush: adapting the Italian building stock will require significant investments. Some estimates reach up to 180 billion euros in the medium term. But stopping at cost would be short-sighted. A house that consumes less is worth more, weighs less on bills and becomes more attractive on the market. At the same time, the transition can create qualified jobs and relaunch a sector we know well, that of construction, but in a finally more sustainable version.
In implementing the Green Homes Directive, the Italian government will be called upon to strengthen the Energy Performance Certificate, introducing more detailed criteria and tools such as the renovation passport, which will guide owners in the interventions to be carried out over time.
