At the Olympic Games venues, Icade experiments with the building’s future

Construction going well, no delays” confirms Florence Shahid-Nurai, director of major projects at Icade. The French real estate group, a subsidiary of Caisse des dépôts, and Olympic construction delivery company (Solideo) met with the press on June 14 to give an update on construction sites for future Olympic games in 2024. On the roof of an apartment building under construction in Sector D, due for completion in December 2023, a representative from a real estate company explains the features of the project.

In total, the company must build 12 residential buildings and one office on this site. A mixed program designed by six architects, which includes various types of housing, 645 rooms, such as social housing, an annex, as well as a student residence. Massive use of wood gives in to this pharaonic project. “Wooden facades are produced in Yvelines to limit the transport and weight of carbon. Here it is a concrete structure, but other buildings have a wooden structure.”the director explains.

However, the material will not be visible for fire safety reasons. The goal is to get at least 30% French wood and the rest European wood. “We secured timber supplies, as well as other materials, before the conflict broke out in Ukraine.‘, Florence Shahid-Nurai clarifies, answering a question from Batiactou about the current crisis of rising prices and shortages of raw materials.

Low carbon concrete in situ

Icade has installed a concrete plant in the Athletes’ Village, which spans three municipalities (Saint-Ouen-sur-Seine and L’Isle Saint-Denis) and will need to accommodate 14,500 people during the event. “We produce low carbon concrete thanks to this plant, we are the only ones who do it in the village, which reduces the CO2 emissions of concrete by 40% compared to conventional concrete.“Icade plans to install solar panels on the roofs of its building complex in the athletes’ village. However, the consumption of the generated electricity will not be reserved for the users of the facility. By the river on the Seine, a few meters from the buildings.

The peculiarity of this project is its reversibility“, – continues the spokesman. Sector D should indeed accommodate 3,000 athletes, but then it will be used by the population of Ile-de-France for living. According to Ikade, 75% of the structural elements will be preserved, in particular, elevators or even walls that Athletes rooms equipped Housing, sports, culture, workspace, concierge, local shops will gather in this 50,000 m² building complex.

Better use of waste and wastewater

An innovative building called The Cycle will also see the light of day in Saint-Ouen. Short circuit solutions for water and biowaste with wastewater treatment will be implemented. “The urine will be separated from the faeces. The former will be used in agriculture, and the excrement will be turned into compost for our green spaces.“, explains Florence Shahid-Nurai. – Gray water (from the shower or sink) will be recycled to flush toilets, washing machines and cleaning common areas.”As we want to go beyond health legislation, we are currently negotiating with the government to get permission to implement these solutions.

The ground floor of the building will be dedicated to “to neighborly life on the topic of ecological transition“And there will be an electric composter in the basement so that residents can store their organic waste.”Our idea is to prove that in France we can do things differently.“, says the head of Icade.

A space “accessible to and including all”

For Solideo Icade, as well as other customers involved in this project, they fulfill the tasks set in the environmental and social charter developed by the company. “We want this project to be part of the broader environmental approach and commitment of COP21.“explains Isabelle Vallentin, Deputy CEO of Solideo, adding that the site welcomes the presence of VSEs and SMEs.The village has been completely designed to be accessible to all, sustainable, inclusive and connected. There have been reflections on thermal comfort, islands of freshness, social diversity through various types of housing, including 2000 social as well as public spaces, so this is a welcoming place.“.

The site’s heritage design was thought out before the Olympics,”this is the reverse of what is usually done“, – notes the director. Air conditioning is prohibited on the territory to facilitate the operation of the heating and cooling network, which will cool housing and offices during periods of extreme heat.”A geothermal system will be installed and heat pumps will be used to supply each building.“, she continues. As for the roads, they are 94% recycled concrete. If an ecological corridor already exists in the area, the Solideo team says they hope to create new ones to improve the biodiversity of the city.
