AR ARCHITECTES is pleased to annouce it’s participation to the “Decarbonize” 2024 trophy with the “Green Amphitheater” eco design project in Rommily-sur-Seine (10), and the energy efficient and bioclimatic renovation for the facades harmonization of the Saint-Just administrative center at Ivry-sur-Seine (94) in France.

The objective of the project “Green Amphitheater” is to reduce the impact on the environment. The infrastructure, as well as the landscaping and the operating building have been designed taking into consideration the natural slope of the plot, the climate (the course of the sun and the prevailing winds). Therefore, the operating building (178.57 m²) was designed bioclimatic and was constructed in wooden frame, insulated by wooden fiber and equiped with green roofs. A sustainable management of rainwater by the use of aquatic ponds and green ditches was also used to create a project with low impact on the environment. Treatment of polluted rainwater by the use of plants, restauration of the biodiversity on site has been achieved. Operating building’s energetic performance : Bbio (79.50 kwh/m²/year) ≤ Bbiomax : 84 kwh/m²/year (French 2012 Thermal Regulation).

The energy-efficient renovation of the Saint-Just Administrative Center aimes to improve the global energy performance of the buildings with the goal of 90 kWhef/m².year (absolute value by 2030 – 15%) in comparison to the buildings’ current energy consumption of : 146 kWhef/m².year. To achieve this goal, our solution is to propose an exterior thermal isolation by biosourced materials for the facades suffering from extreme summer heat, and those suffering from thermal loss in ther winter, to replace all the current windows and doors by double-glazed frames equiped with different heat-protection system. Our mission is also to instore an architectural harmony to all of the building’s facades in order to create a single architectural unity.
