Cities struggle to keep up with the demands of a growing population, including providing adequate transportation, water, electricity, and waste management systems. Sustainability drives modern urbanization, as cities consume large amounts of resources.Sustainable Development: Cities can promote sustainable development by balancing economic growth, social equity, and environmental protection, and by encouraging compact, walkable, and mixed-use development patterns. Residential and commercial buildings consume around 40% of the total energy of the world. The building sector is also responsible for 30% of global greenhouse gas emissions. Saving and optimizing resources during the construction and operations of a building is key to our future.
