Mega buildings for smart cities
In the year 2022 living on earth 7,96 billion peopleAccording to the United Nations, by 2050 the number is expected to increase to 9,7 billion. Half of all people on earth lived in cities in 2009. The biggest challenge is stopping and reversing climate change. City planners must also take demographic change and the scarcity of resources into account.
Technologically, the intelligent networking of more and more areas in the municipalities, in things, in trade and in industry is also moving in. In the smart city or city of the future It's about finding smart solutions for all these complex problems. There are plenty of solution examples and visions, sometimes they build upwards, sometimes longer, they are self-sufficient and intelligently networked. And they should not only be environmentally friendly to implement and operate, but also not violate human rights.
Dogen City – Living on the Floating
The visionaries of the Japanese company N-ARK have developed a floating city. The Dogen City impresses above all because of its size and complexity. According to N-ARK's website, it will be 1,58 km in diameter and about 4 km in circumference. It offers space for around 10.000 residents and 30.000 day visitors and tourists.
infrastructure and housing
The city will be over three infrastructure zones feature: residential, commercial and public zones. The residential zone should include houses, apartments and hotels. The commercial zone accommodates shops, offices and entertainment. Health services, educational institutions and green spaces are provided in the public zone. The Dogen City RING around the floating city includes infrastructure and residential zones. It was designed in the shape of a ship to protect the inner bay and defend against tsunamis.
The city itself is built on a huge platform, thanks to the latest floating and stabilization technology on the open sea swims. This platform uses hydrostatic balancing systems to reduce swell and minimize the risk of flooding even in extreme weather conditions.
Food, energy supply and garbage
The integrated Energy system of Dogen City will generate a large part of the energy from renewable sources such as wind, sun and sea waves, which will be used directly on the platform. An annual energy consumption of 22.265.000 kW is estimated. The city also has advanced water treatment systems that take seawater and turn it into drinking water. Water consumption is assumed to be 2 million liters per year.
On own farms in the form of Seawater Farming and aquaculture complexes as well as production facilities in the city, the food is to be grown and produced, thus ensuring the nutrition of residents and visitors. Dogen City is estimated to need 6.862 metric tons of food a year
In addition, high technology for waste disposal and recycling is used to achieve almost complete self-sufficiency. N-Ark estimates annual waste production at 3.288 t.
Telemedicine for disease-free residents
According to N-Ark's plans, health care is to be implemented in the “realization of a disease-free society through telemedicine based on living space data”. Residents can access and analyze their health data digitally every day. Dogen City is to offer a wellness and health center for tourists.
Last but not least, Dogen City has a state-of-the-art digital infrastructure, including broadband internet access, smart building systems and autonomous traffic systems. The developers are planning to house the servers for the data center in torpedo-shaped containers under water. This should make cooling easier and save power.
There are no concrete plans for implementation yet. The roadmap mentions the year 2023.
The Line - The city of the future
28.07.2022/170/500 | 200 kilometers long, XNUMX meters high, XNUMX meters wide is now being built on more than 26.000 square kilometers the 500 billion smart city "The Line" in Saudi Arabia. Every inhabitant should be able to reach everything they need to live within a 5-minute radius. Mobility will only exist via underground high-speed means of transport and autonomous mobility - conventional automobiles: None, because there are no roads. Model projects like this seem long-term futuristic, but construction is already underway here. One percent of the hyper-networked The Line is already finished, and the first apartments should be ready for occupancy in 2024.
Floating City in Maldives
21.07.2022/XNUMX/XNUMX | The idea life with the water is the basis of the floating city of the future Floating City in the Maldives. The Dutch company dutch docklands carries out the project, no wonder, because the Netherlands is also threatened by the challenges that rising sea levels bring with them. And so people in Europe have been dealing with housing and water for a long time. The island city offers a sustainable and unique quality of life on the Indian Ocean. Several thousand houses and the necessary infrastructure such as a hospital, school, commercial and retail space are to be built. The buildings are attached to a concrete bed and anchored to the seabed. When the water rises, they simply rise with it, and the corals also get a sigh of relief in this smart city.
Technologies and products for the smart city
Green roofs on smart buildings
28.09.2022/XNUMX/XNUMX | The number of currently around 45 million smart buildings According to Juniper Research, this should rise to 2026 million by 115. This corresponds to growth of over 150%, which reflects the rapidly increasing demand for sustainability and energy efficiency. This is not least due to the rapidly increasing energy costs.
Smart buildings (including Smart Home), the intelligent technologies for system monitoring and steering from Heating, air conditioning, lighting and video surveillance are intended to make life for residents safe and comfortable. The aim is to minimize the environmental impact and the consumption of natural resources.
On smart buildings that are not used purely for residential purposes 2026% expected in 90 of global spending on smart buildings. According to analyses, this is because these buildings are less complex and because it is more worthwhile at the scale of managing government and commercial buildings. Intelligent technologies are also increasingly finding their way into schools and universities, hospitals and nursing homes, as well as airports and shopping malls.
In the US, the Biden-Harris administration just got the new one Climate Smart Building Initiative released. On the basis of public-private partnerships, this wants to modernize state institutions through energy-saving contracts. By 2030, up to 2,8 million tons of greenhouse gas emissions are to be saved each year. Around 80 jobs are expected to be created.
Heat islands, architecture and monitoring sensors
In addition to installing smarter Sensors, which help install smart management platforms for energy efficiency purposes, smart buildings also mitigate urban heat islands. The (Paradox engineering) PE Smart Urban Network platform integrates third-party sensors and Internet of Things (IoT) devices to sense and monitor environmental conditions. These are also suitable for green roofs and smart buildings.
Heat islands arise because temperatures in cities tend to be higher than surrounding regions due to the heat absorption and heat storage of materials such as betan and asphalt. The replacement of dark materials such as tar for the roofs has been recommended for a long time. Instead become green planted roofs increasingly popular to combat extreme heat in cities.
Through the jungle of the terminology of the Internet of Things
Exemplary architectural formats are the approximately 700 buildings Green Roof Map in London or the vertical forest by Stefano Boeri in Milan. Such formats already exist in many cities around the world. However, not all green roofs are equally effective: by how many degrees the temperatures can be lowered depends on the variety of plants, the location and other factors. Climate scientists at NASA's Goddard Institute for Space Studies analyzed various green roofs in Chicago and found that larger, intensively green roofs with a variety of plants have a greater cooling effect than extensive monocultures.
One thing is certain: global warming and urban heat islands will intensify. Therefore, green roofs and the conversion of existing buildings into smart buildings are becoming increasingly important Development of climate-neutral cities.

Trend to Smart City through Emotional Artificial Intelligence
21.02.2020 | Artificial intelligence will, according to forecasts, have a major impact on society, culture and the economy. The application of AI in cities and urban environments, Smart City for short, is a hotly debated topic. Emotional artificial intelligence, i.e. AI with EQ, is currently the most explosive in this debate. Minebea Mitsumi deals with the topic of Smart City and AI, because both are product and development branches here.
The emerging technology emotional artificial intelligence aims to allow machines to feel, learn, and interact with human emotions, moods, and intentions. Data such as facial expressions, body temperature, voices or movements are used.
Emotional AI could be used for a variety of purposes. She could for example prevent crime and improve public safety. The idea behind this is to predict individual behavior and intentions. This involves analyzing how a person speaks or moves. This is associated with heart rate and body temperature data.
Of course, emotional artificial intelligence brings with it a great ethical mountain, because it processes highly sensitive, personal data. Researchers at Northumbria University in Newcastle are currently investigating the interface between the opportunities and risks of emotional AI. They canceled the three-year project Emotional AI in Cities: Cross Cultural Lessons from UK and Japan on Designing for an Ethical Life
Artificial intelligence in policing and security
Experiences and valuable know-how from Japan and Great Britain are to be compared here in order to identify advantages and problems when using AI Emotional artificial intelligence in smart cities. The project focuses on the areas of police work and security. The research team will also evaluate the existing system in collecting and using confidential data related to human emotions, especially in public.
The project will develop a Think Tank to provide independent advice on the use of Emotional Artificial Intelligence to governments, businesses, educators and other stakeholders worldwide.
