Acorus uses terracotta to renovate a Parisian residence

Eco-renovation at the service of energy sobriety

Lowering the energy consumption of the Cap Sud residence built in 1979 by the architectural firm Croué & Landaz, such was the ambition of this rehabilitation in the 13th arrondissement of Paris. This vast complex brings together 563 housing units and approximately 2000m² of premises. activities, all spread over three buildings ranging from R+10 to R+14. One of the most important projects managed by Acorus at the request of the co-ownership trustee Loiselet and Daigremont. The objective was to improve the thermal resistance of the building while modernizing its appearance via natural stone cladding made up of more than 99% marble.

For this the following work was carried out:

• Preparation of supports
• Wall insulation
• Cladding of stone facades
• Replacement of carpentry
• Waterproofing of balconies and loggias
• Replacement of locks
• Replacement of body guards.

After two years of work, this 7,7 million euro program is coming to an end in this residence located at 5-13 Place de Rungis, in Paris.

Terracotta: natural, ecological and sustainable

Terreal, this terracotta material, was stapled to the facade. Used for more than 5.000 years, terracotta is timeless. This ancestral construction material draws its elements from a 100% natural raw material, clay. Inert and therefore recyclable, it requires no maintenance and allows reduced maintenance for long-term cost control. Resistant to frost, shock, UV, it is also non-combustible and above all offers major energy performances: reduction of thermal bridges, exploitation of the inertia of the building, low thermal conductivity, summer comfort.

For José Dos Santos, in charge of the site: “Unalterable and standing the test of time, terracotta brings relief, strength and identity to the buildings it clads. The cladding of balconies and facades in terracotta is both durable, weather-resistant and offers the added bonus of a refined, simple and modern aesthetic. Furthermore, the comfort felt by the occupants is improved, they tell us, thanks to the elimination of cold zones. »

For Philippe Benquet, Chairman of the Acorus Group: “We are always concerned about the ecological footprint of the buildings we renovate, by offering our customers eco-responsible products and materials as much as possible. In this way, natural stone and terracotta met this need. It has exceptional energy performance, it is naturally ecological and recyclable: three advantages which are widely taken into account today. Because thanks to the energy savings they allow, the maintenance, renovation and rehabilitation solutions installed daily by our 850 technicians constitute gains in the energy consumption of homes. »
