The second decade of the 21st Century has seen dramatic improvements in our global urbanized environments and cities. MIT Urban Planning described that a renaissance of environmental thinking is creating demand for new urbanization models based on systems that are more energy efficient, digitally connected, and ecologically sustainable. McKinsey & Company found out that the ways in which cities develop and cope with such
rapid urbanization are of huge importance to citizens. Cities are the main source of global economic growth and productivity, and they account for most resource consumption and greenhouse gas emissions. Urban development therefore matters to the wellbeing of all the world’s occupants.
In addition, most cities have opportunities to reduce the environmental impact of existing infrastructure. It is proven by The 2011 retrofit of New York City’s Empire State Building that the approximately 80-year-old building was transformed into a landmark of green construction by implementing cutting-edge technologies, including automated monitoring and controls systems, and high efficiency cooling equipment. The $13.2 million invested in energy efficiency reduced annual energy consumption by 38%, generating a payback period of 3.5 years and reducing greenhouse gas emissions by 100,000 metric tons over 15 years.
