Sustainable Design and Construction

Sustainable construction considers the complete lifecycle of a building, from the choice of initial materials to demolition and recycling and refers to the use of environmentally preferable practices and solutions in each of the phases.

It applies to both renovation and retrofitting of existing buildings and construction of new buildings, whether residential, commercial, public or private.

It aims is to minimise the environmental footprint, and focuses on thermal and acoustic comfort, well-being, indoor air quality and safety.

Professionals in the construction sector tend to estimate the cost of constructing a green building to be 17% higher than the cost of building a conventional structure. This estimate is over three times higher than the actual figure, which is only about 5% higher. This is the conclusion of a study carried out by the W.B.C.S.D in the context of the “Energy Efficient Buildings” project.

Isover contributes actively to educating the market and developing sustainable construction practices setting up training programmes for building sector professionals to raise their awareness of energy-efficient solutions for new and renovated buildings.

The Lifecycle approach

Third-party verified Environmental Product Declarations are used to communicate the results.

We have succeeded over the years in reducing the environmental footprint of our solutions and we will continue to do so thanks to our Eco-Innovation policy.  In order to contribute to a more resource-efficient economy, we develop waste recycling solutions and increase the recycled contents of our products.

We promote the use of life cycle assessments (LCAs) in the building industry and carry out LCAs for all our products, to know and improve their environmental footprint. To give confidence in our communicated LCA results, our environmental product declarations (EPDs) are verified by an independent third party. You can recognise our commitments for Life Cycle Assessments and verified Environmental Product Declarations with the “EPD verified” pictogram.
