The CECB Certificate: What Does It Really Reveal About Your Property?

Information That Many Property Owners Are Unaware Of

You probably know the size of your property, the year it was built, or even the number of rooms it has. But do you know how energy-efficient it is?

This information is becoming increasingly important in the real estate market. It influences not only a property’s running costs, but also its comfort, attractiveness and, in some cases, its market value.

To measure this performance, there is a tool specifically designed for this purpose: the Cantonal Energy Certificate for Buildings, better known by its French acronym, CECB.

What Is the CECB?

The CECB is an official document used to assess the energy performance of a building.

Like the energy label used for household appliances, it assigns a rating from A to G.

This assessment takes into account, in particular:

The building envelope (walls, roof, windows)
Energy consumption
The heating system
Hot water production
The property’s overall energy requirements

A building rated A has excellent energy efficiency, while a building rated G generally has lower performance and higher energy consumption.

Why Is This Information Useful?

A property’s energy rating primarily provides a better understanding of its energy performance.

It provides concrete information about:

Heat loss from the building
Potential heating costs
The level of thermal comfort
Improvements that could be considered

For many property owners, this information is difficult to perceive on a daily basis. A house may seem comfortable while still having significant potential for energy efficiency improvements.

The CECB helps provide an objective assessment of this situation.

A Factor Increasingly Considered by Buyers

Energy-related concerns are playing an increasingly important role in real estate projects.

When purchasing a property, many buyers now seek to anticipate their future costs and any work that may need to be carried out.

In this context, energy performance provides additional information that helps assess a property as a whole.

It does not, of course, replace traditional criteria such as location, the quality of the finishes or the size of the plot, but it is now one of the factors regularly considered when comparing properties.

Is a Poor Rating Necessarily a Problem?

Not necessarily.

Many properties built several decades ago receive average or low ratings without necessarily losing their appeal on the market.

The purpose of the CECB is not to penalise a building, but to provide a clear overview of its energy performance.

This information allows property owners to identify improvements that could potentially be made in the medium or long term.

In some cases, targeted measures can significantly improve a property’s performance and reduce its energy consumption.

How Can You Obtain a CECB?

The certificate is issued by a certified expert who analyses the building and its technical characteristics.

The document then provides a standardised and easy-to-understand assessment of the property’s energy performance.

Is It Mandatory?

The CECB is not always mandatory: this depends on the canton and the situation (sale, renovation, replacement of the heating system, etc.).

For example, in the canton of Vaud, the CECB is mandatory when selling an existing house, but not when selling a new-build house off-plan.

Better Understanding Your Property to Make Better Decisions

The CECB is a valuable tool for understanding the energy performance of your property, but it represents only part of the information needed to assess the value and potential of a property.

Having an overall view makes it possible to identify opportunities, anticipate certain constraints and make informed decisions, whether renovating or selling.
