Toronto Becomes First City To Mandate Green Roofs. Summer is just around the corner, and for those who live in big cities, that means spring warmth will soon give way to searing heat.

Toronto Becomes First City To Mandate Green Roofs

Green roofs can help regulate city temperatures, giving people, and the electrical grid, a much needed break. Toronto is the first city in North America with a bylaw that requires roofs to be green. And we're not talking about paint. A green roof, also known as a living roof, uses various hardy plants to create a barrier between the sun's rays and the tiles or shingles of the roof. The plants love the sun, and the building (and its inhabitants) enjoy more comfortable indoor temperatures as a result.

Toronto's new legislation will require all residential, commercial and institutional buildings over 2,000 square meters to have between 20 and 60 percent living roofs. Under the direction of Mayor Richard Daley the city of Chicago put a 38,800 square foot green roof on a 12 story skyscraper in 2000. Image via Flickr/pnwra. SDG Index and Dashboard.

What Do We Need to Build Sustainable Cities? Every so often, I find it important to reset and to re-envision what a successful future looks like.

What Do We Need to Build Sustainable Cities?

This article seeks to take a step back and revisit the fundamentals of what the building of a sustainable city requires. The footprint of cities is a heavy contributor to the un-sustainability of life on the planet; each city takes much more than its total land area to support the population that lives, works, and plays there. It’s a mind boggling fact that over half of the world’s population lives in urban areas, and this number will increase to about two thirds of the world’s population by 2050.

That means that today, 3.9 billion people are living in cities, and that number will continue to rise exponentially. Tokyo, Japan is today’s most populous city, with 38 million dwellers; followed by Delhi, India with a population of 25 million people and expected to grow to 36 million by 2030. The Ideal City The View From Main Street. 8 Overarching Urban Systems That Make a City Sustainable. Because cities are so complex - as complex, you might say, as a living organism - sustainable cities are much more difficult to achieve than green buildings or environmentally friendly cars.

8 Overarching Urban Systems That Make a City Sustainable

For example, it’s not enough to have sustainable buildings in your city if they are all really far apart and everyone has to drive long distances to get around -- that would be like eating a salad followed by fried chicken. Simply stated, one strategy on it’s own is simply not enough to make an entire city sustainable, rather what's needed is a series of strategies. According to author Timothy Beatley in his book Green Urbanism: Learning from European Cities, there are eight overarching systems that need to work together to make a city sustainable.

In 8 Months, Humanity Exhausts Earth's Budget for the Year August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year.

Earth Overshoot Day

We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. Just as a bank statement tracks income against expenditures, Global Footprint Network measures humanity’s demand for and supply of natural resources and ecological services. And the data is sobering. In 1993, Earth Overshoot Day—the approximate date our resource consumption for a given year exceeds the planet’s ability to replenish—fell on October 21. Earth Overshoot Day, a concept originally developed by Global Footprint Network partner and U.K. think tank new economics foundation, is the annual marker of when we begin living beyond our means in a given year.

Are the world’s megacities too big?

This column suggests that policies aimed at reducing the dispersion in city sizes will hardly improve the wellbeing of the people who live there. If anything, in some developing countries, such as China, large cities may actually be too small. Department of the Environment and Energy, Australian Government. Big Energy Question: How Do We Make Cities Sustainable? He world's cities occupy 4 percent of the Earth's land area, yet they are home to more than half of the world's people.

Big Energy Question: How Do We Make Cities Sustainable?

By 2030, that percentage will swell to 60 percent. Indeed, the United Nations projects that cities will absorb most of the world's population increase between now and 2050—more than two billion people—with the vast majority of urban expansion taking place in the developing world. How to Build a Sustainable City. Can Technology Make Green, Sustainable Cities? What is at the heart of a sustainable city?

Can Technology Make Green, Sustainable Cities?

If you look at this ranking, which considers Vancouver, San Francisco, Oslo, Curitiba, and Copenhagen, as the most sustainable cities in the world, it appears that lots of green technology is key. Vancouver is heavy with renewable energy including lots of hydropower and it has the lowest per capita carbon footprint on the continent. San Francisco has great air quality, waste management and commuting options. Oslo is literally green, with two-thirds of its area covered with trees. Making cities sustainable with urban agriculture. Even in remote places such as Irkutsk in Siberia with its very short growing season, I have seen people cultivate an great variety of vegetables, including cucumbers and tomatoes, in well insulated greenhouses, both for home supply as well as for sale in We need to find efficient and environmentally enhancing ways of feeding ourselves.

To this end we need to initiate new processes of 'ecological densification' - making good, well considered use of limited areas of land - to meet increased food demands by increasing numbers of people. In many countries large minorities of people grow food in and around cities. Making our cities attractive and sustainable. Smart cities: innovation in energy will drive sustainable cities.

Top Content On 4 December 2015, the Council of Australian Governments Energy Council released the National Energy Productivity Plan (NEPP) and initial Work Plan of measures. The NEPP provides a framework and an initial economy-wide work plan designed to accelerate action to deliver a 40 per cent improvement in Australia’s energy productivity by 2030. In better coordinating energy efficiency, energy market reform and climate policy, it brings together new and existing measures from across the COAG Energy Council’s work program, as well as from the Commonwealth and industry.

The NEPP aims to improve energy productivity by driving: more productive consumer choices, through measures which make consumer energy choices easier, help business compete and provide more efficient incentives; andmore productive energy services, through measures which support innovation, competitive modern markets and consumer protection.

Sustainable House Day 2016. This Mexico City Building Eats Smog For Lunch. There are plenty of architects these days who are doing their best to design buildings that are energy efficient and utilize green technology. And then there’s Allison Dring and Daniel Schwaag of the Berlin-based firm Elegant Embellishments. For Torre de Especialidades, a hospital with a new tower currently under construction in Mexico City, the duo has developed a tile called proSolve370e, which will cover the façade of the building. The tile’s shape and chemical coating will help neutralize the chemicals present in the city’s smog.
