Building for the climate: How it's done in Switzerland

While some parts of the United States struggle with drought, others are faced with more water than they know what to do with. Minnesota reconstructs roads and drainage systems in order to be more prepared for the large amounts of rain fall they have received, largely due to climate change.

In Memphis, a creative blight-reduction initiative called 25 Square Blocks broke down the city into blocks. Inspectors were able to quickly identify all the violations and fix them, using the same amount of funding, but less time, as the old call-and-respond model.

Geography and climate change challenge the viability of sea-level cities in Vietnam, but architects, researchers, and urban planners work together to find creative solutions. One architect in Ho Chi Minh City designed green roofs to absorb the rainwater that causes floods.

A growing number of people in the famously crowded Tokyo metropolis are becoming ‘city farmers’, planting crops atop tall buildings or deep underground. In an age of detrimental climate change, urban cultivation and green roof agriculture will soon be necessary as food, water and energy resources become scarcer.

Passive houses can generate more energy than they consume but are expensive to build. Non-profits across the nation are getting low income families into these types of renewable homes with state subsidies and volunteer work.

Too much solar and wind power in Germany is overloading their grid. A firm developed a new technology that uses super-fast batteries and software to hold intermittent wind and solar power when more than needed is generated.

As a state with robust populations of wildlife, Montana has had its share of roadkill. Its Department of Transportation developed animal shelving, a type of wildlife crossing, to enable safe passage for small animals who need to cross the road. The measure, combined with other types of crossings, has reduced animal-vehicle collisions by half.

New York City suffered from fires that erupted in overcrowded, run-down apartments. Then the city sleuthed through residential records and found that landlords who foreclosed let their properties fall apart and ignored safety-code violations. Greater Toronto wants to expand upon New York City’s method by using transportation surveys, census data and computer data to build transit lines.

While billions of taxpayer dollars are allocated each year to support shelters and social service initiatives, homelessness remains a persistent problem in the U.S. - in 2013, an estimated 610,000 people slept without shelter every night. All over the country, people are building "tiny homes" to give to the homeless, providing them with shelter, a bathroom, and a kitchen for less then the cost of a shelter.

Renovating and furnishing a home can be hugely expensive. Homeowners who are renovating on a budget, and want to do so in a way that is evironmentally friendly, can find recycled luxury kitchens and other lightly used fixtures at stores like Green Demolitions.
