How open source is designing the sustainable cities of the future

Key Concepts

• Carbon Emissions: Greenhouse gases released into the atmosphere, primarily from human activities, contributing to climate change. Cities are identified as major contributors.
• Open-Source Software: Software whose source code is made publicly available, allowing anyone to use, modify, and distribute it. It fosters collaboration and transparency.
• City Energy Analyst (CEA): A specific open-source software tool designed to simulate and analyze energy use within urban environments.
• Sustainable Cities: Urban areas designed to minimize environmental impact, optimize resource use, and enhance the well-being of their inhabitants, often incorporating renewable energy and efficient infrastructure.
• GitHub Co-pilot: An AI-powered pair programmer that assists developers by suggesting code and functions in real-time, aiming to increase coding efficiency.
• Energy Demand: The total amount of energy required by a city or system to meet its various needs, including heating, cooling, transportation, and electricity.
