A new house delivered in the middle of July, large south-facing windows, and the indoor temperature soaring beyond bearable levels within the first week. This scenario is becoming increasingly common in recent constructions. Choosing the equipment for a modern house is not just about ticking options off a catalog: it involves balancing real comfort, energy efficiency, and the durability of the chosen solutions.
Summer Comfort in a Modern House: The Trap of All-Glazing Without Passive Protection
Large glazed surfaces have become a hallmark of contemporary housing. They bring in natural light, visually enlarge the rooms, and enhance the property’s value upon resale. The problem arises with the first heatwaves.

The RE2020 has introduced a heat overload indicator (degree-hours, or DH) that requires considering summer comfort from the design stage. One can no longer simply add air conditioning as an afterthought: passive design takes precedence over corrective equipment. In practical terms, this means that the choice of sunshades, exterior shutters, roof overhangs, or adjustable projection blinds is an integral part of the house’s equipment, just like the heating system.
When selecting the equipment offered by iDéco Maison, it becomes clear that this logic of balancing passive and active solutions now permeates all ranges, from joinery to ventilation solutions.

Installing an air conditioner in every room is not prohibited by regulations, but it is an approach that is costly to operate and contradicts the bioclimatic logic of the RE2020. It is better to invest in well-thought-out cross-ventilation, exterior solar protections, and a ceiling fan before considering a supplementary air conditioning unit.
Heat Pump and Heating: What the Decline of Gas Changes in Equipment Choices
The new housing market is moving towards massive electrification of uses. The heat pump (PAC) is establishing itself as the reference solution for heating and the production of domestic hot water, while gas continues to decline in new construction.
This shift has direct consequences on the rest of the equipment. With an air-to-water heat pump, one sizes a low-temperature underfloor heating system that also works for passive cooling in summer. This is a structuring choice: it determines the type of flooring, ceiling height, and furniture positioning.
Concrete Criteria for Sizing Your Heat Pump
- The living area and volume of the rooms determine the necessary power. An undersized heat pump runs at full capacity and wears out prematurely.
- The actual insulation of the building is as important as the power of the device. A high-performing heat pump in a poorly insulated envelope remains an energy sink.
- The noise level of the outdoor unit deserves special attention, especially in dense areas where neighbors are close. Feedback on this point varies according to brands and installers.
It is recommended to have an independent thermal study conducted before validating the heat pump model. The builder often proposes a standard equipment that does not always match the actual profile of the housing.
Integrated Equipment and Discreet Home Automation: Choosing What Ages Well
Catalogs are filled with connected gadgets. Touch mirrors, screen refrigerators, voice assistants integrated into walls: the temptation for over-equipping with technology is strong. In practice, many of these devices become obsolete or break down before the end of the house’s ten-year warranty.
The equipment that stands the test of time shares a common point: they solve a concrete problem without relying on a proprietary software ecosystem. A connected switch on an open protocol lasts longer than a wall-mounted tablet locked to a single manufacturer’s app.
What Deserves Investment Right from Construction
Retractable outlets in the kitchen countertop, multi-level lighting, and wired network pre-wiring in each room are discreet yet structuring choices. They are not visible, do not go out of style, and facilitate daily use for years.
In contrast, concealed appliances (dishwashers hidden behind a facade panel, integrated hoods) require consideration for maintenance. An appliance that is hard to access will be poorly maintained, and thus replaced sooner.
Interior Layout and Comfort: Balancing Living Space and Storage
A modern house plan often favors open volumes. Open kitchens to living rooms, elimination of hallways, mezzanines: the result is spectacular on paper but poses acoustic and storage issues in daily life.
Before choosing furniture or partitions, it is beneficial to test the layout in real conditions. Placing tape on the floor to the exact dimensions of the rooms, simulating traffic with cardboard boxes, checking that the washing machine door does not block the passage: these simple actions prevent costly mistakes.
- Plan for at least one closed closet per living area, even in a minimalist layout. Visible clutter destroys perceived comfort.
- Glass or slatted partitions separate spaces without cutting off light, an effective compromise between open volume and intimacy.
- Acoustics should be addressed during construction, not afterward. An absorbing false ceiling in the open living area radically changes sound comfort.
The garden extends this balancing act. An outdoor space oriented northwest provides natural shade in the late afternoon during summer, reducing reliance on cooling equipment for adjoining rooms.
The choice of equipment for a modern house is less about the quantity of options checked off than about the coherence between the building, the local climate, and the actual habits of the occupants. A sober and well-thought-out home costs less to maintain than a house packed with technologies that counteract each other.
