MASE DECREE 28 OCTOBER 2025: WHAT CHANGES FROM 3 JUNE 2026 FOR APE, RENOVATIONS AND “COMMERCIAL” PROPERTIES

The world of construction has a new date to mark in red on the calendar: June 3, 2026. This is the date on which the new MASE Decree of 28 October 2025 will come into full force, which will update the rules of the game for our homes. For our studio, which has been involved in energy redevelopment and restoration for 15 years , this step is not just bureaucracy: it is a paradigm shift that will directly affect living comfort and, above all, the commercial value of real estate. We have analyzed the text for you, this is what it means concretely for your wallet and your well-being.   DOWNLOAD HERE THE NEW MINISTERIAL DECREE 28/10/2025   FROM “ENERGY CLASS” TO “REAL HEALTHINESS” The big news is the attention to the health of those who live in the house. If in the past there was a lot of focus on numbers, today we focus on physical well-being. What’s changing: The verification of the absence of risk of mold and condensation formation is strengthened, with particular attention to the so-called “thermal bridges”, i.e. those critical points such as corners and balconies where heat is dispersed. The business advantage: A house renovated according to the new criteria is not only a house that consumes less, it is a healthy home. For buyers, knowing that the property is checked against the risk of mold according to the latest standards is a determining factor in the purchase choice.   THE ELECTRIC CHARGING REVOLUTION Compared to ten years ago, when electric cars were a rarity, the new rules introduce specific obligations for sustainable mobility. What’s changing: For new buildings and major renovations, the obligation to set up the infrastructure for charging electric vehicles is triggered. This applies to both residential and non-residential buildings, with specific requirements based on the number of parking spaces. The business advantage: A condominium or villa already prepared for the electric car has a higher market positioning. It is not necessarily a question of installing the column immediately, but of preparing the ducts to avoid expensive breakage work in the future.   INSULATION AND WINDOWS AND DOORS: CONFIRMATION OF THE STANDARDS OF EXCELLENCE The new rules confirm the crucial importance of thermal insulation for saving on bills. What’s changing: The thermal transmittance limits (the ability to retain heat) for redevelopment are consolidated on high efficiency levels. For example, for exterior walls in many areas of northern Italy, the required values guarantee high energy performance. Even for windows and roofs, the requirements remain stringent to ensure maximum comfort. The business advantage: Maintaining these high standards means protecting the value of the property over time. High-performance insulation translates into low operating costs and a pleasant indoor temperature in every season.   “SMART” SYSTEMS: THE HOUSE THAT REGULATES ITSELF It is no longer enough to have an efficient boiler; The system must know how and when to work. What’s changing: The focus is on automation and intelligent control. In the event of replacement of the generator, for example, the installation of regulation systems for each room is required, to manage the temperature room by room. The business advantage: Thermal comfort becomes customizable. This technological detail is highly appreciated when selling or renting, as it guarantees the end user total control over expenses and tailor-made comfort.   Comparison Chart: Old vs New Here is a summary of the main operational differences between the previous legislation and the one that will come into force:

Scope	Ministerial Decree 26 June 2015	MASE Decree 2025
Electric mobility	Almost absent / Separate regulations.	Dedicated chapter (Chap. 6). Infrastructure and channeling obligations for residential and non-residential parking spacestag.
Thermal bridges	Calculation present but often simplified.	Strict obligation. New detailed tables and specific verification of the mold risk on thermal bridgestag.
Redevelopment	Less restrictive thermal limits.	Stricter limits. E.g. Zone E walls: limit 0.28 W/sqmK. Zone E windows: limit 1.40 W/sqmK.
Automation (BACS)	Incentivized but not always mandatory.	Mandatory (Class B) for non-residential buildings with 290kW systems >and a strong push on regulation for single rooms in the residential sector.
APE Certification	Based on 2015 standards.	More accurate. The new calculation methods will reward buildings that integrate renewables and home automationtag.
