DPE: why new construction is always one step ahead
Le ECD, or Energy Performance Diagnosis, assesses the energy consumption of a home and its impact on greenhouse gas emissions. It awards a rating ranging from A (excellent) to G (very energy-intensive).
In recent years, this ranking has become a central criterion in real estate, especially for rentals. A good DPE means more economical, more comfortable housing... and a higher market value.
Since January 1, 2025, things are getting tougher for landlords. G-rated housing is now prohibited for rentalBy 2028, it will be the turn of F-rated housing. Clearly, thermal sieves no longer have a place in the rental market. The Climate and Resilience Act is redrawing the rules of the game.
In this context, the new construction becomes an ideal solution. Why? Because it makes it easy to achieve a good energy rating. Thanks to the RE2020 regulations, new homes incorporate the latest standards in insulation, ventilation and thermal performanceThe result? A DPE often rated A or B, without any additional effort.
Opt for a construction with the correct DPE, therefore, means anticipating legal obligations while enhancing the value of your investment. In an increasingly selective market, it also means meeting the expectations of tenants, who now favor economical and sustainable housing.
The DPE creates a two-speed market : on the one hand, old housing that is difficult to make profitable without work; on the other, new houses ready to rent, well-classified, efficient.
At Maisons SIC, we design each project to meet the requirements of tomorrow. A construction with a good ECD, it’s your guarantee of peace of mind, today and for a long time.
Building means ensuring a good DPE without any work
Are you planning to build your house? Good news: it's today the easiest way to get a good DPE, without having to plan expensive work. And for good reason, new construction incorporates technical choices and materials designed for energy performance from the outset.
Thanks to the RE2020 environmental regulations, new houses must meet strict standards in terms of insulation, ventilation, heating and bioclimatic design.
These performances are preconceived from the plans and integrated throughout the construction site. No unpleasant surprises when you hand over the keys: the accommodation is immediately compliant with regulatory thresholds.
A good DPE is a home that consumes little energy, emits little CO₂, and allows reduce heating bills. It's also an asset in the event of resale or rental. Since 2025, poorly classified housing (G, soon F) has been gradually banned from rental. By building today, you avoid these future constraints.
Another advantage: no need for renovation work to improve your home's performance. You won't have to redo the insulation, change the windows, or replace an old boiler in ten years. You're starting from a healthy, sustainable base, optimized for comfort and savings.
Building also means choosing the long-term peace of mindYou are the owner of a modern, well-listed property, ready to welcome your family in the best conditions.
Contact Maisons SIC : we integrate all these requirements from the design stage of your project. Building orientation, high-performance equipment, responsible materials: we think of everything to guarantee a DPE optimal, without compromising on comfort.
6 levers to improve your DPE from the design stage
Building a house is much more than a choice of size or architectural style. It is also a unique opportunity tooptimize your energy performance from the start, without having to plan future work.
Here are 6 concrete levers to activate from the design stage to guarantee a excellent DPE.
1. Think about the location based on the sun
The orientation of the building plays a key role in thermal comfort. A well-oriented house naturally captures the sun's heat in winter and protects itself from it in summer. By positioning the living rooms to the south, We take advantage of free light and heat. Conversely, smaller openings to the north limit heat loss. It's a simple and 100% natural solution for effortlessly reducing energy consumption.
2. Insulate beyond standards
La RE2020 already sets strong demands in terms of insulation. But nothing prevents you from going further. Reinforced insulation of walls, attics, and floors helps retain heat in winter and coolness in summer.
By choosing high-performance and durable materials (wood wool, cellulose wadding, expanded polystyrene), you improve interior comfort while optimizing your DPE.
3. Provide quality ventilation
A well-insulated home must also be well-ventilated. VMC (Controlled Mechanical Ventilation) performing is essential to ensure healthy air, remove humidity and limit heat loss.
A double flow VMC even allows heat to be recovered from the outgoing air to heat the incoming air. The result: renewed air, a stable temperature and energy savings.
4. Equip with high energy performance appliances
The choice of equipment has a direct impact on the DPE. For heating, hot water or household appliances, favor devices classified A+++ or labeled renewable energy.
An air/water heat pump or a thermodynamic water heater, for example, consumes little and offers excellent performance. In construction, these choices can be integrated from the design stage, without significant additional cost.
5. Limit thermal bridges from the planning phase
Thermal bridges are areas of rupture in the building's insulation, often located at the junction between two materials. They cause heat loss and can affect energy efficiency.
From the plans, it is possible to provide suitable construction details : continuity of insulation, treatment of angles, use of thermal breaks... By acting upstream, we avoid energy weaknesses that are difficult to correct after the fact.
6. Anticipate usage with smart home automation
Home automation allows you to better control your consumption on a daily basis. Programming heating room by room, controlling roller shutters according to sunlight, monitoring consumption in real time: all these solutions promote responsible use of energy.
By integrating these devices from the design stage, we prepare the house for intelligent, comfortable and economical management.
A good DPE is not a matter of chance. It is built from the very first thoughts on the project. At Maisons SICwe We offer personalized studies to guarantee our clients high-performance, sustainable housing with no work required.
