Bativert SA and Grange Immobilier have recently formalized a study mandate to address the challenges of bringing various properties into energy compliance, with a particular focus on villas and small buildings. We are carrying out this mission to help owners define the appropriate strategy within the given timeframe. We also work on projects involving larger buildings, according to various operational scenarios.
Bativert, a 360° renovation proposal
Are you a building authority, property manager or owner? Entrust us with your renovation, rehabilitation or conversion program in line with cantonal guidelines. We'll manage all the administrative, conceptual and technical phases on your behalf, for comprehensive or à la carte projects, from study to project management.
Owners, standardization is an obligation
In September 2022, Geneva introduced energy regulations designed to reduce the energy consumption of buildings and accelerate the move away from fossil fuels for heating. These regulations are based on the Heat Expenditure Index (HEI), which ranks buildings from A to G according to their energy efficiency in relation to their heated surface area. The HDI threshold is 125 kWh per square meter per year. Buildings exceeding this threshold must reduce their consumption: the most energy-intensive must be renovated, while others must undergo an energy audit followed by optimization measures.
Houses and small buildings are also concerned: their owners must assess their HDI and will be subject to the same requirements, from 2029 to 2034*, including the additional 3-year period voted by Geneva's Grand Council in March 2024.
Global thinking for consistent results
Don't take the risk of carrying out this work without the support of a professional. From audit to project management, as well as assistance to the project owner, our teams will draw up a sanitation program that meets your financial and operational constraints. We have over 20 years' experience in standardization, including:
- Audit and planning
- Administrative procedures and subsidies
- Renovation of buildings
- Thermal networks (natural gas, hydrothermal, geothermal, solar, biomass, waste heat from businesses).
Financing solutions are available
Fear of complexity and costs often make homeowners hesitate. Bativert simplifies the task for you: we work with you to draw up an action plan and timetable, taking into account the existing situation, your financial capacity and available subsidies. Renovation offers substantial savings in an exponentially rising energy market. You'll be a winner! To convince you, entrust us with your property's performance study, to give you a clear view of the project.

Villas and small buildings with fewer than five dwellings have an additional 3-year deadline:
- IDC greater than 222 kWh/m2.yr (800 MJ/m2.yr) until December 31, 2029,
- IDC greater than 180 kWh/m2.yr (650 MJ/m2.yr) from January 1, 2030 until December 31, 2033,
- IDC greater than 153 kWh/m2.yr (550 MJ/m2.yr) from January 1, 2034.
