An estimated 5 billion people, 54% of the world’s population will live in cities by 2030. With an increasing world population, it’s important to accommodate everyone in a modern, sustainable fashion. For all global citizens to survive and prosper, we need new, intuitive urban planning that creates safe and affordable cities. It is estimated that 5 billion people will be living in cities by 2030. Urbanization has brought enormous challenges, including growing numbers of slum dwellers, increased pollution, inadequate sanitation, sewage systems and infrastructure. Better urban planning and management is necessary to have an inclusive, safe and resilient community.

CITY STATISTICS

95% of urban expansion in the next decades will take place in developing world

Cities are becoming less dense as they expand and grow, challenging the sustainable patterns of urban development and transportation.

9 out of 10 people who live in cities are breathing polluted air that did not meet the World Health Organization’s standards

Half of humanity – 3.5 billion people – lives in cities today and 5 billion people are projected to live in cities by 2030.

As of 2016, 90% of urban dwellers have been breathing unsafe air, resulting in 4.2 million deaths due to ambient air pollution.

883 million people live in slums today and most them are found in Eastern and South-Eastern Asia.

The world’s cities occupy just 3% of the Earth’s land, but account for 60-80% of energy consumption and 75% of carbon emissions.

More than half of the global urban population were exposed to air pollution levels at least 2.5 times higher than the safety standard.

Wooden Condo’s In Toronto

Architectural Group Penda has proposed to make a 16 floor, completely wooden high-rise in Toronto. The apartments are meant to resemble a large tree and will be filled with greenery and shrubs to help cool the building and reconnect urban areas with natural materials. Another aspect is the down-construction of the building-traditionally steel, copper and other metals are not recycled once a building has reached the end of its life cycle. Penda’s vision for the wooden high rise would render large parts of it reusable for another project. Furthermore they look to capitalize on the carbon tax cut offered by the Canadian government (10-20% of cost) for sustainable development.

Cool your home without using any energy

Researchers at the University of Wyoming have developed a product that can be used to cool down houses, businesses and even power plants, without the use of energy or water.  The product is a foil or film slightly thicker than aluminum foil, that reflects the suns rays back into space, and also allowing the surface underneath to shed its own heat at the same time.  Professor Gang Tan, Department of Civil and Architectural Engineering says ” Just 10-20 square meters of this material on rooftops could nicely cool down..family homes in the summer.” When used on solar panels, they can cool the panel and recover an extra 2-3% of the panels efficiency.
