Cool Ways To Get Sustainable Cities
People get more and more involved in future sustainable cities.
Global warming, CO2 and melting icecaps are reasons for citizens to turn their lights off, responsible water use and taking a bike instead of the car.
But there are regions were people do more. Let’s have a look at great sustainable initiatives.
Palo Alto, Baltimore, Portland, Melbourne and Rotterdam
More trees in cities such as Palo Alto, Baltimore, Portland, Melbourne and Rotterdam not only decrease the temperature in cities (up to 7 degrees), they are also improving air quality.
Trees reflect more solar energy into the atmosphere. Trees also help absorb CO2 from the air and decreasing air pollution. But there is more: children, adults and their pets, love green cities and urban forests. It makes them feel more connected to nature and feel more conscious to sustainable behavior themselves.
Gondolas as aerial tramway
Medellin, Caracas, Rio and La Paz
Some cities have trouble to implement buses or subways because of steep landscape, narrow streets, and congested roadways.
Cities like Medellin, Caracas, Rio de Janeiro and La Paz have a solution by using cable-car systems or ‘Gondolas’ as public transportation. Gondolas run on electricity, make a minimum amount of noise, and reduce traffic congestion.
Brooklyn, Singapore, Amsterdam, Gaza, Hong Kong, Tokyo
Green roofs isolate and the vegetation filters out particulates, nitrogen, oxides and soot from the air and take up CO2 from the atmosphere. Using green roofs as gardens and farms helps provide the city’s population with slow food.
Many cities and buildings could benefit from incorporating a green roof into their infrastructure!
- Solar Roadways and Green Pavement
Amsterdam, Eindhoven, Berkeley
The Dutch cycle nation has it’s first solar bike path, SolaRoad.
Rows of crystalline silicon solar cells are embedded in concrete and then covered with translucent tempered glass. Thousand miles of paths and roads can be transformed to renewable energy power roads.
Solar Roadways could replace a large percentage of asphalt, decreasing carbon emissions and increasing our renewable energy.
And this is so logical: Researchers of Berkeley studied ‘cool pavement‘ asphalt technologies.
Like cool roofs, cool pavements reflect as much as 30 to 50 percent of the sun’s energy, compared to only 5 percent for new asphalt (and 10 to 20 percent for aged asphalt).
Cool pavements will be available in different hues, including green, blue and yellow, and their solar reflectance value depends on both color and material.
