Smart Cities: How They Reduce Global Warming

Smart Cities and Climate Change: How Technology is Saving the Planet

Smart cities have emerged as an innovative solution to building a more efficient and sustainable urban future.
But what do we mean by smart cities? What are the factors that define them, and can they truly improve quality of life while reducing emissions?
In this article, we dive into the concept of smart cities and explore how they have evolved from an idea into a tangible reality adopted by many countries, especially Saudi Arabia, as part of its national vision for sustainable digital transformation.

Greenhouse Gases

Greenhouse gases are gases in the Earth’s atmosphere that can absorb infrared radiation emitted by the Earth, trapping heat and increasing air temperature. Without these gases, the Earth’s average surface temperature would be around -18°C instead of the current average of 15°C.

Experts warn that if the Earth’s temperature rises by 1.5°C above pre-industrial levels, many of the changes on the planet will become irreversible, pushing humanity towards a climate disaster due to the increase in greenhouse gas emissions.

The Role of Contemporary Architecture

How does contemporary architecture relate to climate change, and can it effectively reduce greenhouse gas emissions while increasing renewable energy production?

Many studies have examined the causes of global warming and the need for collective human action to address it.

Architecture is one of the areas extensively studied, as building design impacts emission rates, which can be reduced through simple techniques with long-term economic benefits by relying on renewable energy generation.

This is where the concept of sustainable architecture comes in, focusing on preserving resources efficiently over the long term, protecting the rights of future generations to non-renewable resources, and reducing building emissions, which are among the highest contributors to environmental issues.

Green Architecture

Green architecture helps protect the environment by integrating buildings with their surrounding ecosystem, reducing the negative impact of concrete structures through the strategic use of vegetation to restore biological balance. While climate remains the dominant factor, the roles of wildlife, plant life, and soil are also significant in maintaining ecosystem health.

Environmentally Friendly Architecture

Attention has increasingly shifted toward environmentally friendly architecture due to ongoing economic crises, fluctuating oil prices, and the depletion of non-renewable energy resources.

The focus now is on creating environmentally friendly buildings by utilizing available energy sources to reduce consumption, ensuring a sustainable future. This concept has given rise to bio-climatic skyscrapers, designed using renewable energy technologies that integrate local climate data, resulting in high-rise structures that are energy-efficient and environmentally responsive.

Dynamic Architecture

Dynamic architecture is a branch of green and sustainable architecture, featuring buildings that generate their own energy using thermal energy produced by the structure itself. Many industrialized countries are setting minimum sustainability standards for existing buildings, while all new constructions adhere to standards related to thermal insulation and water reuse, contributing to sustainable urban environments.

Smart Cities

The concept of smart cities was developed to assess and enhance energy and water efficiency, using objective performance standards to evaluate all types of buildings, including commercial, residential, industrial, sports, healthcare, hospitality, and educational facilities that apply sustainability standards.

Over the years, the idea of smart cities has driven governments to adopt the latest technologies promised by companies to eliminate urban challenges and increase efficiency.

Policymakers are leveraging application-based solutions and the Internet of Things (IoT), using sensors to collect vast amounts of data, enabling informed decision-making and enhanced adaptability in urban management.

Expected to house one million residents along a 170-kilometer stretch on the Red Sea coast, The Line will operate on 100% clean energy, representing one of the world’s most complex and challenging infrastructure projects. Construction was set to begin in late 2021, aiming to create 380,000 jobs and contribute SAR 180 billion ($48 billion) to the GDP by 2030.

These advancements highlight how smart cities help reduce greenhouse gas emissions contributing to global warming by using integrated ICT systems to support economic, social, and environmental goals while improving the quality of life for residents.
