Minergie standard in Geneva: HPE obligation, levels, costs and procedures
Minergie is a Swiss building label, run by the Minergie Association, that certifies new and renovated buildings according to their energy consumption, their comfort and their use of renewable energy.
In Geneva, the label remains voluntary, since the cantonal energy law requires new buildings to meet the high energy performance standard (HPE).
This article covers the obligation and the requirements, then the levels and their ECO supplement. It then deals with daily life, cost, certification, grants, renovation, the cantonal energy certificate for buildings (CECB) and verification.
Is the Minergie label mandatory in Geneva?
No, the Minergie label is not mandatory in Geneva: the cantonal law requires new buildings to meet the high energy performance standard (HPE), of which the label is one proof.
Article 15 of the energy law (LEn) imposes this standard on new buildings and extensions. The standard can be proven in one of four accepted ways.
- the Minergie label, with its P and A levels and its ECO supplement;
- the model energy provisions of the cantons (MoPEC 2014);
- a CECB Plus of class B/B;
- a justification at 80% of the SIA 380/1 values.
This decision tree summarises what the cantonal law requires depending on the project: the HPE standard and its four ways of proof for a new building or an extension, the heat consumption index for a renovation.
The very high energy performance standard (THPE), which is more demanding, is imposed on public buildings but not on private owners. For renovation, no label is required: the obligation concerns the heat consumption index (IDC).
What requirements does the Minergie label impose?
The Minergie label imposes six requirements.
- Minergie index: energy demand below a limit value, 38 kWh/m² of reference area for a typical new house.
- Envelope: heat demand at 90% of the MoPEC limit.
- Heat production: no fossil fuel.
- Ventilation: automatic air renewal, opening the windows is not enough.
- Summer comfort: a maximum of 100 hours of overheating.
- Embodied emissions: a mandatory limit value.
What is the difference between Minergie, Minergie-P and Minergie-A?
Minergie, Minergie-P and Minergie-A differ first in the strictness of the limit energy index: 38, 35 and 26 kWh/m² of reference area for a typical new detached house.
The table compares the three levels (2026.1 regulation).
| Level | What it aims for | Distinctive requirement | For whom |
|---|---|---|---|
| Minergie | Base of the label | Heat demand at 90% of the MoPEC limit | Standard project |
| Minergie-P | Reinforced envelope | Heat demand at 70% of the limit, measured airtightness | Minimal heating |
| Minergie-A | Energy autonomy | Annual self-production that covers the needs | Maximum autonomy |
For most new houses, Minergie is enough; -P and -A aim at minimal heating or autonomy.
What does the ECO supplement guarantee?
The ECO supplement guarantees compliance with requirements on health (air quality, materials, noise, daylight) and on construction ecology (reuse, water, biodiversity), in order to obtain a healthy and ecological building.
It is combined with one of the three levels to give Minergie-ECO, Minergie-P-ECO or Minergie-A-ECO.
What does a Minergie home change in daily life?
A Minergie home changes four aspects of daily life: ventilation, humidity, noise and summer heat.
- Ventilation: gentle ventilation renews the air and the windows can still be opened; according to the Minergie association, replace the filters up to three times a year.
- Humidity: the winter target is 30 to 40%; if the air is too dry, turn the heating down.
- Outdoor noise: rooms stay protected from noise without giving up fresh air.
- Summer heat: ventilation has only a limited effect on overheating; open the windows at night.
How much does a Minergie building cost?
A Minergie building costs between 2.8% and 6.9% more in gross investment than a building that meets the basic legal requirements, according to the Minergie association (multi-family housing with three dwellings).
Minergie certification costs, excluding VAT, CHF 1,400 up to 250 m² of energy reference area and CHF 1,900 from 251 to 1,000 m², compared with CHF 2,600 and CHF 3,400 for the same bands in Minergie-P and -A.
How do you obtain the Minergie label in Geneva?
To obtain the Minergie label in Geneva, follow four steps, from the project file to the final certificate.
- Submit the provisional application on the labels platform to Minergie Agence romande (Sion), the competent office for Geneva.
- Obtain the provisional certificate, valid for three years; the fees are due when it is issued.
- Request the final certificate on completion, attesting that the building complies with the file.
- Accept a possible on-site visit: at least 20% of certified buildings are inspected.
This timeline shows the four certification steps, from the provisional application to the on-site visits.
The regulation in force at the time of application applies to the whole procedure.
What grants are available for a Minergie building in Geneva?
Grants for a Minergie building in Geneva come under the GEnergie programme and cover 3 measures, in CHF per m² of energy reference area, depending on the use.
- HPE renovation, Minergie variant: 150 to 390.
- THPE renovation, Minergie-P variant: 190 to 470.
- New Minergie-P(-ECO) construction: 30 to 75.
The cantonal energy office (OCEN) must receive the application at least 14 days before work starts. Labelled renovations are not eligible for the individual measures M-01 to M-11 and M-13.
Can an existing building be renovated to the Minergie standard?
Yes, an existing building can be renovated to the Minergie standard, on the basis of a Minergie, Minergie-P or Minergie-A renovation certificate, with requirements less strict than those for new buildings.
For housing, the label offers 5 standard solutions that allow certification without calculation. The label is one route to energy renovation among others, alongside work carried out measure by measure.
What distinguishes Minergie from the CECB?
Minergie differs from the CECB by its nature: a construction standard label as opposed to a certificate that ranks a building's energy status from A to G.
The CECB (cantonal energy certificate for buildings) is produced by a certified expert and is valid for 10 years. In Geneva, no CECB is required by law at the time of sale, but GEnergie requires it for certain grants.
How can you check that a home is Minergie-certified?
To check that a home is Minergie-certified, consult the public list of buildings on minergie.ch, where each building carries a certificate number.
Ask the seller for the final certificate, not the provisional one. A home that meets the legal standards is not necessarily labelled.
