Buildings are to blame, in part, for today's staggering rates of global warming. As they constitute a whopping 39 percent of the worldwide carbon emissions, it's not possible to stop the catastrophic temperature rise without making buildings greener. Luckily, the proliferation of net-zero energy construction is doing exactly that, turning this environmental liability into an opportunity.
Cities gave birth to civilization as we know it, according to many historians and archeologists. Since the first cities in Mesopotamia came to be thousands of years ago, the growth of global urbanization has been unstoppable. By 2050, more than two-thirds of the world's population will reside in cities, a jump from today's 55 percent.
By 2050, almost 70 percent of the world's booming population will be living in cities. In addition to the challenges of climate change, an exponential urban sprawl might accelerate issues like pollution or extreme weather vulnerability.
