New image and beautiful "overall" performance for this 70s office building where no heavy work had been done since its construction and which presented such discomforts that it became "unusable".
Complete recovery of the insulation of the envelope, its airtightness and thermal bridges.
Development of shared areas on the garden level for training with installation of LED luminaires running on presence and graduation of the luminosity.
Development of co-working spaces on the ground floor with specific acoustic study. Independent spaces mutualisable with the outside wooden terrace.
Release of the R + 2 shelf for tenants and / or co-owners with full accessibility of the site and independent management.

Owner approach of sustainability
1. Make buildings compliant with current regulations. O Accessibility O Fire O Asbestos 2. Bring these buildings delivered in the 1970s (45 years) to the levels of performance, comfort, ease of operation and operating costs of a new building. O Work on their envelopes and facades, heating solutions and evaluate their costs. 3. Provide working conditions consistent with the activities housed in the building (offices, call center, meeting, shop window ...): O Allow for evolutions. O Make this building attractive. O Make new digital solutions possible. 4. Examine the solutions of pooling of spaces and resources. O Flexibility of use. O Savings. 5. Making these buildings valuable to their heritage.
New image and beautiful "overall" performance for this 70s office building where no heavy work had been done since its construction and which presented such discomforts that it became "unusable". Complete recovery of the insulation of the envelope, its airtightness and thermal bridges: • Wooden tunnel walls of the existing structure for busy site intervention and encapsulation of asbestos products. Insulation distributed in these 42cm coat walls. • Exterior insulated exterior walls of minimum 20cm, removing all thermal bridges from the existing post / concrete beam structure. • Terracotta shingle finish for resistance, maintenance and the "earth" side for the Cité de l'Agriculture et des services. • Double-breaking aluminum jointed joinery Uf = 1,1 with high-performance double glazing. • Complete renovation of roof terraces with 240mm polyurethane and treatment of acroteres. Then, implementation of "comfort and health" solutions - summer heat - by double-stream ventilation with 2 plants per level and management of bioclimatic facades by solar protection: • Horizontal sunlight breezes on individual management and centralized by sun sensor to avoid summer overheating by wind sensor to wind up the blinds in case of strong wind and hourly programming to secure the building at night. • Vertical and colored vertical sunscreens create masks while animating the facades. Energy performance achieved at the level of a new building: • Factor 5 for consumption on all items, ie 289 to 56.4 kWh / m².an. • Factor 10 for heating consumption, ie 245.8 to 24.9 kWh / m².an. O Decrease by 50% of heating surfaces. Development of shared areas on the garden level for training with installation of LED luminaires running on presence and graduation of the luminosity. Development of co-working spaces on the ground floor with specific acoustic study. Independent spaces mutualisable with the outside wooden terrace. Release of the R + 2 shelf for tenants and / or co-owners with full accessibility of the site and independent management.

The oldest building material in the world, terracotta is obtained by the firing of clay. It is this natural raw material that gives it its strengths.
• Economical and lightweight
• Durable and maintenance-free
• Simple and fast rail mounting
• Simple, long-skinned cladding: up to 150 cm
In total agreement with the site "The City of Agriculture and Services"
