Environmental certifications: a benchmark for designing sustainable acoustic projects

In a construction project, environmental certifications have become essential. They guide technical choices and structure environmental objectives.

But what is an environmental certification in the building sector?
An environmental certification is a framework used to assess the performance of a building, a product, or an industrial process based on criteria such as energy, materials, and occupant comfort.

Between ISO standards, FDES, LCA, and labels such as HQE®, LEED® and BREEAM®, their role is still often misunderstood. They do not all cover the same aspects, and their impact on a project is not always clear.

Increasingly structuring environmental requirements

Today, a building project must integrate several dimensions:

  • reducing environmental impact
  • energy performance
  • indoor air quality
  • occupant comfort, particularly acoustic comfort

Certifications provide a framework to assess these criteria. However, it is still necessary to understand what they actually measure.

Three levels of certification to understand

Not all environmental certifications assess the same aspects. They can be grouped into three categories.

 

Company certifications: the production framework

ISO 14001 and ISO 50001 standards apply to industrial sites.

  • ISO 14001 governs the management of environmental impacts
  • ISO 50001 aims to improve energy performance

They ensure how products are manufactured, not their performance.

 

LCA and FDES: product impact 

Life Cycle Assessment (LCA) measures the impact of a product across its entire lifecycle:

  • raw materials
  • manufacturing
  • transport
  • use
  • end of life

This data is available in FDES, which are used in building environmental calculations.

They make it possible to compare products and integrate their impact into a project.

Building certifications: overall project performance

Frameworks such as HQE®, LEED® and BREEAM® assess a building as a whole.

They include various criteria:

  • energy
  • materials
  • comfort
  • indoor air quality

It is not the product that is certified, but the building. Materials simply contribute to the final result.

The integration of certifications into Eurocoustic solutions

Eurocoustic offers acoustic solutions with environmental data (FDES) designed to contribute to building certification criteria such as HQE®, LEED® or BREEAM®.

 

Controlled industrial processes

Production relies on certified management systems, ensuring:

  • controlled management of environmental impacts related to production (energy, resources, waste)
  • continuous improvement of practices

 

Actionable environmental data

Products come with FDES, used in Life Cycle Assessment (LCA) calculations.

They make it possible to:

  • quantify their environmental impact
  • compare them with other solutions

A contribution to the objectives of certified projects

Acoustic ceilings contribute to several criteria:

  • acoustic comfort
  • indoor air quality
  • material selection

Concrete benefits for projects

The use of products with FDES and certifications makes it possible to:

  • facilitate environmental calculations
  • verify compatibility with certification frameworks (HQE, LEED, BREEAM)
  • improve certain measured performances (acoustics, IAQ)

A practical application in commercial spaces

In a certified project, acoustic ceilings contribute to:

  • improving speech intelligibility
  • reducing reverberation
  • maintaining good indoor air quality

Certifications to support better decision-making

Environmental certifications help provide a clearer understanding of a project, provided that distinctions are made between:

  • production (ISO)
  • products (FDES, LCA)
  • the building (HQE, LEED, BREEAM)

In an acoustic project, they are mainly used to compare products and to check whether they meet the project requirements.

FAQ
Do all acoustic products have an FDES?

No, not all acoustic products necessarily have an FDES. An FDES (Environmental and Health Declaration Sheet) is a voluntary approach that provides data based on a Life Cycle Assessment (LCA).

Products that have one offer greater transparency regarding their environmental impact, which facilitates their integration into projects with environmental requirements. Conversely, the absence of an FDES can make calculations and comparisons between solutions more complex

Does a certified product guarantee a certified building?

No. A certified product or a product with environmental data alone does not guarantee the certification of a building.

Certifications such as HQE®, LEED® or BREEAM® assess the overall performance of the building (energy, materials, comfort, indoor air quality, etc.). Products contribute to these objectives, but certification depends on the entire project and the consistency of technical choices.

Do environmental certifications also measure acoustic comfort?

Yes, some environmental certifications include occupant comfort, particularly acoustic comfort, among their evaluation criteria.

However, acoustics is only one of the parameters taken into account, alongside indoor air quality, energy performance, and materials. Acoustic solutions therefore contribute to improving the building’s overall performance, without being the sole determining factor.

When should FDES data be integrated into a project?

FDES data should be integrated from the design phase of a project.

It is used in Life Cycle Assessment (LCA) calculations to evaluate the environmental impact of material choices. Integrating it early makes it possible to compare solutions, optimize environmental performance, and anticipate certification requirements.

Why do Eurocoustic solutions facilitate certified projects?

Eurocoustic solutions support certified projects by fitting into a comprehensive approach that combines environmental data and technical performance.

They notably provide Environmental Product Declarations (EPDs / FDES) that can be used in Life Cycle Assessment (LCA) calculations and contribute to key building certification criteria, such as acoustic comfort, indoor air quality, and material selection.

This combination helps simplify analyses and secure product choices within a certified project.

 
 
 
 
What is the difference between environmental certification and regulation?

Regulations establish mandatory requirements that must be met in a construction project (for example, regarding energy or safety).

Conversely, environmental certification is a voluntary process that allows for the evaluation and recognition of a project's overall performance according to a given standard.

It often goes beyond regulations by incorporating additional criteria such as comfort, environmental impact, and usability.

Are environmental certifications mandatory?

No, environmental certifications are not mandatory for most projects.

They are based on a voluntary approach, often initiated by the project owner to highlight the environmental quality and overall performance of the building.

However, they are increasingly used as a benchmark in calls for tenders and can become a significant differentiating factor.
