Sunimplant: an avant-garde hemp building

The Sunimplant project participated in the latest edition of the Solar Decathlon, which was held for the first time in Africa. The international competition, which takes place every two years, challenges teams including students to develop highly efficient and innovative buildings that run solely on solar energy. 

Sunimplant aims to be truly sustainable and therefore not only uses technology to address higher energy efficiency requirements and climate emergency demands, but also considers the health of habitats using remediation knowledge. 


A smart city has been created in Kazakhstan, called Aqkol, 100 kilometres from Nur-Sultan. Step by step, it is currently being transformed into a smart city.

Aqkol has 14 000 inhabitants. The first space vehicle complex in Kazakhstan was commissioned here in 2005. According to Alimzhan Yesetov, Director General of Tengri Lab, the digitalisation of the city started last spring.

All the city's subsystems send data to the single secure platform that powers the smart city. All data is displayed on the video wall installed at the Aqkol Situation Centre.

"Let's return the rivers to the city"

In 2019, the public initiative "Give the rivers back to the cities" united citizens around the Podborenka River, which flows through the entire length of Izhevsk. 

In an urbanised environment, the Podborenka River has become deserted due to water pollution, poor stormwater management, pollution from roads and industry, soil erosion and landfills in the valleys. Therefore, the primary objective of the project is to increase urban resource efficiency and to create new scenarios for resource use in a small river basin. 

Rebuilding Ukrainian cities with 3D virtual modelling

The Ukrainian government has selected Egis, Dassault Systèmes and B4 to mobilise their expertise and experience in 3D virtual technologies, construction and engineering to rebuild urban areas damaged by the invasion.

The two-phase project approach includes a collaborative reconstruction cost analysis and a general design exercise in the Chernihiv area and the city of Chernihiv.

Virtual twinning is at the heart of the collaborative project, which aims to optimise urban infrastructure, resources, sustainability and quality of life for residents.

The parks

Parks are the highest sustainable lifestyle in the world, providing a net-zero lifestyle for 150,000 residents. The city will produce 100% of its energy, water and food on site to become a self-sufficient destination.

The 1700 hectare smart city is planned for the eastern region of South Africa. The development will provide a variety of mixed-use centres such as residential, health, tourism, entertainment, retail and education centres. The 40 000 residential units will be spread over 12 residential areas.

Budapest Solar Map

The Budapest Solar Map of the Municipality of Budapest and the Hungarian Solar Solar Association developed by the Budapest Solar PV Association.

The map is based on the real estate registry map database (building- building maps, floor plans, parcel numbers) which the Municipality of Budapest uses for the The Municipality of Budapest receives updated data from Lechner Nonprofit Kft. every six months. The building floor plans show the status of the buildings in 2021, but no errors or omissions in the construction of the buildings have been reported to the competent authorities.

Bladeless wind turbine

Aeromine Technologies has developed a ground-breaking bladeless wind energy solution that can be linked with existing solar energy systems and building electrical systems, allowing commercial property owners to meet the growing demand for on-site renewable energy.

Aeromine stands out with its particularly considerate of the environment. It doesn't make any sound, hurt or kill birds with its "motionless turbines." The system captures and amplifies the wind from each building using aerodynamics akin to racing car airfoils.

Energy from waste

100 kilometers north of Helsinki, Finland, in the city of Lahti, is the world’s first eco-gas fueled power plant. Lahti Energy’s new Kymijärvi II power plant runs on SRF that is gasified, cooled and cleaned before combustion. The plant produces 50 MW of electricity and 90 MW of district heat for the city of Lahti. It was officially inaugurated in May of 2012.
Eco-friendly – and eco-smart!

River basin restoreation

In the heart of western Europe, on the Dutch-Belgian border, work began in 2007 on a major habitat restoration project. The 45-kilometre stretch of the river, which originated in the Ardennes as the Meuse and reached the Dutch plain at Maastricht, where it is now called the Meuse, has been restored to its natural state at great cost in terms of time and money. The 1200 hectare RivierPark Maasvallei (Meuse Valley River Park) on the border between the Netherlands and Flanders in Belgium is now one of the most attractive destinations for green tourism.
