The term Smart City has gained popularity, as have terms like “sustainable,” “recyclable,” or “circular economy.” It has become a fad that politicians and city administrators frequently mention, but the reality is much more complex. It is not enough to have Wi-Fi in libraries or applications to check the schedule of public transport. To really be a smart city, it is necessary to have a comprehensive approach that covers various key aspects focused on sustainability, energy efficiency, technological interconnection and the quality of life of citizens.
The concept of Smart City should not be used lightly, although it is often overused. In this article, we will delve into the characteristics y fundamental pillars that define a truly smart city.
Characteristics of smart cities
When politicians are asked what makes their city a Smart City, the answers can be varied and sometimes vague. They often talk about digital infrastructures, such as the availability of Wi-Fi in public spaces, mobile applications to make citizens' lives easier, or bicycle lanes. However, these are only components of a much broader picture.
For a city to be considered truly “smart,” it must integrate diverse systems and technologies that work together to improve the urban experience. This includes aspects such as energy efficiency, mobility, environmental management and citizen participation.
- Technological innovationSmart cities use cutting-edge technologies to connect with citizens, from sensors that monitor security and environmental aspects to intelligent transportation systems.
- Sustainability: The aim is to reduce environmental impact through initiatives such as the use of renewable energy, smart buildings and efficient transport.
- Citizen-centric: Good smart city management involves ensuring that citizens fully benefit from all technological advances and that there is active participation through digital platforms.
Pillars of a smart city
The definition of Smart City is often associated with six key pillars that form its basic structure. Below, we explore each of them:
1. Efficient and sustainable energy management
One of the most important components of smart cities is the Energy. The interconnection between energy production and consumption points, as well as the use of renewable sources, is essential for a city seeking sustainable development. Smart buildings share surplus energy, ensuring efficient use of available resources.
An excellent example of this is the system of district heating in San Sebastian, which allows industries to give up surplus energy to heat homes instead of wasting it. In this way, the rational use of energy improves both quality of life and sustainability.
2. Sustainable mobility
Transport in a Smart City It must be efficient, accessible and environmentally friendly. Advances in digitalisation allow for better traffic management and optimised use of public transport. Traffic sensors, optimised routes and electric vehicles play a key role in reducing the carbon footprint.
For example, automated lighting systems in parks and streets can adjust to the presence of pedestrians to maximise energy efficiency without compromising safety. The result is faster, more comfortable and less polluting mobility.
3. Smart buildings
Smart buildings are those designed to offer more efficient energy consumption and better control of their environmental impact. This can be achieved through sustainable construction processes and the integration of technologies such as home automation to regulate the use of electricity and water automatically.
Furthermore, the rehabilitation of existing buildings to improve their energy efficiency is vital. The combination of these initiatives reduces operational costs and improves the quality of life of those who live or work in these spaces.
4. Sustainable Urbanism
El sustainable urbanism is another of the central pillars of Smart Cities. This involves rethinking the design of cities to integrate residential, commercial, sports and leisure areas, facilitating access for all citizens, including those with reduced mobility.
It also seeks to implement policies of sustainable construction, using materials and techniques that minimise environmental impact. Urban planning should also promote social integration and ensure that all areas of the city are interconnected.
5. Technological interconnection in the city
In a interconnected city, citizens must be able to interact with their environment through multiple devices. This includes not only internet connectivity, but also the interconnection of sectors as varied as transport, energy or public services, creating an optimal digital infrastructure.
Citizens can actively participate through digital platforms, reporting incidents or providing suggestions, and in return obtaining real-time information on public services and transport. This type of interconnection is not only digital, but also environmental and economic, fostering sustainable development and efficient use of resources.
There is no city that meets all these requirements today, but many are on the way to achieving this. The concept of Smart City It goes far beyond technology; it encompasses efficient management of resources, an improvement in the quality of life of citizens and, above all, the creation of a sustainable environment focused on the future.
As architect Jaime Lerner said, the battle for sustainability will be won or lost in cities. The intelligent development of cities is key to facing the challenges of the future.
