Avenir Permaculture is a French regenerative landscape design company (founded 2022, Nouvelle-Aquitaine), built on its founder’s 20 years of experience designing regenerative landscapes for private owners, businesses and municipalities. Its flagship solution, LOWASIS, answers a simple paradox: while cities overheat, every roof sends rainwater straight to the sewer. LOWASIS turns this abundance into urban coolness.

A LOWASIS island is a turnkey nature-based cooling island (typically 200 to 400 m²) combining: rooftop rainwater harvesting and buried storage sized for about 75 days of drought autonomy; a four-layer planted canopy, from trees to ground cover, that shades and transpires; smart drip irrigation driven by soil-moisture sensors, so plants keep cooling during heatwaves instead of shutting down; and a small biodiversity pond. It uses zero drinking water and is designed to keep working under drought restrictions, when conventional green spaces lose their cooling power.

LOWASIS creates shaded, cooler outdoor spaces for residents, students and employees, and can help cool the surrounding buildings. Co-benefits: biodiversity, soil life, carbon storage, stormwater management and de-sealing of urban soils. Each island is co-designed and planted with its future users. Our purpose: reconnecting people with the rest of the living world.

Every component has been tested for about 20 years on our experimental site at La Courdemière (Vienne, France). Combining them into a single, instrumented island is what we are now deploying, starting with a pilot prepared with the University of Poitiers under an ERDF call on urban heat islands (current maturity: TRL 6).

In Barcelona, we are looking for municipalities, landscape contractors, water utilities and research teams to test LOWASIS in Mediterranean climates.

Cities throw away the water that could cool them. LOWASIS is an all-in-one cooling island fed exclusively by rainwater: buried storage, sensor-driven irrigation and a four-layer planted canopy that keeps transpiring during heatwaves, when unirrigated vegetation shuts down. Zero drinking water, designed to operate during droughts. Every pilot is instrumented: where the science stops, we measure cooling, carbon and biodiversity services together

Our ecological commitment is regeneration itself: every LOWASIS island leaves the site more alive than it found it. We de-seal urban soils, rebuild living soils, plant diverse multi-layer vegetation, create habitats for biodiversity and give rainwater back to the ground instead of the sewer, with zero drinking water. Users co-design and plant their island, and each pilot is scientifically monitored with the University of Poitiers. No certification yet (small company).

Founder: 20 years designing regenerative landscapes for private clients, businesses and municipalities; experimental site at La Courdemière (France). LOWASIS (launched 2025): first paid order, a private client hosting a LOWASIS island; ERDF urban heat island project with the University of Poitiers (Futuroscope campus, 250 m² pilot island, submission Oct 2026); ongoing discussions with a municipality in Vienne for a 250 m² island.

For more than 25 years, Simpliciti has been diversified its offer with ever more innovative and efficient solutions. 

We support cities and companies to monitor and optimize water networks, waste collection activities and public transportation. 

In this context, we provide solutions to 2000+ municipalities such as Lyon Métropole, Bordeaux, Brussels, Cannes, and companies (Keolis, Veolia, Paprec, Suez, Urbaser) and also UN HCR. 

In Europe, Middle East, Africa and Canada, we deliver our solutions by integrating new functionalities but also by associating local partners for more local service. 

Water management: 

SIMPLICITI and Urbasense conceive and implement innovative solutions to digitalize the operation of water networks with applications in 3 main areas.  

• Sanitation and rainwater networks: our customers are the network operators. 
• Irrigation of green spaces: our clients are the municipalities.  
• Access to drinking water: our clients are NGOs. 

These solutions generate knowledge about networks from connected sensors and business applications, with main benefits:  

1. Improve performance and operating efficiency, 

2. Preserve the resource: often water savings (50 to 70% for intelligent watering), 

3. Reduce the environmental footprint: less carbon footprint (shorter intervention routes: 40%), less waste released into the natural environment. 

Waste management: 

SIMPLICITI provides digital platform GEORED for managing waste. This solution allows: 

• Traceability of services,  
• Optimization of waste flow management, 
• Optimization of collection tours.  

Our innovation capacity combined with our expertise allows us to offer customized and avant-garde solutions for sustainable cities like CITI’ID AND Hummbox Smart Watering (2 of 1000+ solutions elected by Solar Impulse Foundation), which assures traceability of collected bins or new functionalities of waste recognition to detect dangerous or forbidden objects in real time.

Urbasense, a Simpliciti Group company, delivers smart irrigation solutions combining connected sensors, hydraulic network monitoring and agronomic expertise. By continuously measuring soil moisture, detecting leaks and remotely controlling irrigation systems, Urbasense adapts watering to the real needs of vegetation. The result: up to 54% water savings, elimination of unnecessary watering, reduced operating costs and more sustainable management of green spaces.

At mube, our mission is to contribute to urban renaturation in a responsible way, to build greener, more resilient cities that are more pleasant to live in.

mube designs autonomous, connected, water-efficient irrigation systems as well as innovative greening structures, particularly vertical ones. These solutions enable our industrial partners to create and monitor a new generation of green urban infrastructure.

The mube Smart Irrigation Controller (SIC) is a smart, autonomous and water-efficient irrigation system that can be remotely controlled. Connected directly to the city’s water network and equipped with an integrated soil moisture sensor, it optimises water use according to actual needs. Connected to the mube platform, the system can be remotely configured and provides operating data, irrigation history and activity logs, enabling smart, centralised monitoring of all installations.

Mube is committed to greener, more resilient cities through nature-based solutions. Its planted urban columns promote biodiversity and help improve urban environments, while smart irrigation systems optimize water use and reduce waste. As a member of Bpifrance’s Coq Vert community, Mube demonstrates a strong commitment to ecological transition and sustainable innovation.

Mube installed a green infrastructure column in Liverpool, integrating planting, lighting and Smart City equipment into a single asset. Its 128 plants across 15 species grew rapidly thanks to MUBE’s patented irrigation system, enhancing biodiversity, CO₂ capture and the urban environment. The project is estimated to save 4.1 tCO₂e over 40 years compared with a conventional solution.
