Do you know exactly how much energy your home uses each year and how much it actually costs you? The Cantonal Building Energy Certificate (CECB) answers that question by clearly assessing the energy performance of homes in Switzerland. In this article, discover in simple terms what the CECB is, why it has become essential, and how it can help you improve your home over the long term while cutting your energy bills.
Definition and role of the Cantonal Building Energy Certificate (CECB)
The Cantonal Building Energy Certificate (CECB) is an official Swiss document. It assesses a building’s energy performance. In plain terms, it tells you whether your home uses a lot or a little energy.
The CECB grades buildings on a scale from A to G:
- A means excellent energy efficiency.
- G indicates very poor performance and high energy consumption.
This certificate plays several important roles:
- Informing owners about the energy state of their property.
- Encouraging renovation and better building insulation.
- Meeting cantonal regulatory requirements on ecology and sustainability.
- Supporting sale or rental by giving clear information to potential buyers or tenants.
For example, if you’re considering a real-estate investment, the CECB helps you quickly identify the works needed to improve energy security and make long-term savings. Class Orga delivers your full energy compliance project in Geneva through a fully integrated approach.
The CECB is issued after an audit or assessment carried out by a certified expert. This specialist analyses your building and hands you a detailed report with practical recommendations to improve your energy performance and reduce your impact on the climate.
What are the different types of CECB available?
The standard CECB: energy assessment of the existing building
The standard CECB is the baseline certificate. It assesses the energy performance of an existing building. This assessment measures energy consumption and highlights weak points, helping plan renovations by priority. For example, it can reveal poor insulation of walls or external joinery. It gives you a clear view of the current state of the building.
The CECB Plus: detailed report with improvement recommendations
The CECB Plus goes further. On top of the standard assessment, it delivers a detailed report with specific recommendations to improve energy efficiency. It includes:
- Concrete renovation measures
- An estimate of investment costs
- Potential energy savings
For example, it may recommend improving roof insulation or installing a more efficient heating system that relies less on fossil fuels.
The CECB New Building: certification for new constructions
The CECB New Building concerns new constructions. It confirms that your project meets current standards in ecology and sustainability. This certificate helps prove the energy quality of a new property. It also supports compliance with current regulations and strengthens the property’s value on the real-estate market.
Is the Cantonal Building Energy Certificate (CECB) mandatory in Switzerland?
Situations in which the CECB is mandatory
In Switzerland, the CECB is mandatory in specific situations. It mainly depends on cantonal regulations. For example:
- When selling a residential building in certain cantons, the CECB is required to inform the buyer about the property’s energy performance.
- To obtain public subsidies for energy renovation, the certificate is often requested as proof of improved energy efficiency.
- In certain cantons, when replacing a heating system with an installation using fossil fuels, a CECB can be required.
Cases where the CECB is optional but recommended
In other situations, the CECB isn’t mandatory but is strongly recommended:
- Before starting renovation works, carrying out a CECB makes it possible to clearly identify the building’s weak points in terms of insulation and energy consumption.
- If you’re considering a real-estate investment, the CECB helps you precisely assess the future costs linked to the property’s energy use and durability.
- To raise your property’s value, having a recent CECB is an additional asset when putting it up for sale or rent.
How is the CECB energy label calculated?
Assessing the efficiency of the building envelope
The building envelope covers walls, external joinery, roof and floors. The CECB assesses its efficiency by checking insulation and the ability to retain heat. A good envelope reduces energy losses, improves thermal performance and leads to financial savings.
For example, a building well insulated with mineral wool will get a better grade than an older building without insulation.
Measuring overall energy efficiency
The CECB measures the building’s overall energy consumption. That includes:
- Heating
- Domestic hot water
- Ventilation
- Air conditioning
- Lighting
This measurement helps determine how much energy is needed to keep the indoor environment comfortable. The less your building consumes, the better its certification.
Calculating direct CO₂ emissions
The CECB also takes into account the direct CO₂ emissions linked to the building’s energy consumption.
For example, an oil-fired boiler emits more CO₂ than a heat pump powered by renewable electricity.
This calculation assesses the building’s environmental impact and its compliance with sustainability and ecology standards.
Switzerland has set a goal of carbon neutrality by 2050. To achieve it, the Federal Council has announced the entry into force of the ordinance linked to the Climate Protection Act. Among the planned measures, financial support encourages the replacement of oil and gas heating in residential buildings to promote more sustainable solutions.
What steps should you take to obtain the Cantonal Building Energy Certificate (CECB)?
To obtain the Cantonal Building Energy Certificate (CECB), you follow a few simple steps. Here is how to proceed:
1. Find an accredited provider such as Class Orga
The first step is to contact an accredited provider able to support you with energy compliance (CECB – CECB+) such as Class Orga. We are certified to carry out the energy audit required for certification.
2. Prepare the required documents
Before the expert’s visit, prepare the following documents:
- Building plans (architect plans, technical plans)
- Recent energy consumption bills (heating, electricity)
- Information on renovation works already carried out
3. Carrying out the energy audit
The expert carries out an on-site visit to assess the energy performance of your building. They check in particular:
- The general condition of the building
- The quality of the insulation
- The heating and hot water systems
- The ventilation and external joinery
4. Issuing the certificate and energy optimisation
The expert carries out an on-site visit to assess the energy performance of your building. They check in particular:
- The general condition of the building
- The quality of the insulation
- The heating and hot water systems
- The ventilation and the windows
What costs and benefits are linked to obtaining the Cantonal Building Energy Certificate (CECB)?
Average CECB costs by building type
The cost of a Cantonal Building Energy Certificate (CECB) varies depending on several criteria. In general, the price depends on the type of building, its size and its complexity. Here is an indicative average:
- Single-family house: between 500 and 800 CHF
- Small building (up to 6 apartments): between 800 and 1,200 CHF
- Large building or commercial property: from 1,200 CHF
These costs include the energy audit, the expert’s travel and the delivery of the certification report.
Long-term economic and ecological benefits
Getting a CECB brings significant economic and ecological benefits:
- Energy savings: identifying weak points helps reduce consumption and energy bills.
- Higher property value: an energy assessment close to category A increases the value of a property on the real-estate market.
- Meeting standards: compliance with cantonal regulations on energy efficiency.
- Ecology: lower greenhouse gas emissions, a contribution to climate protection.
For example, better thermal insulation can cut heating consumption by up to 40%, a strong long-term investment.
