Climate change is a global issue, one that architects, designers, and engineers are tackling head-on. Their efforts are particularly visible on city skylines, which are sprouting rooftop gardens, “living walls,” and solar arrays. These technologies, especially when combined, can result in “net zero” buildings, meaning structures that draw no energy from the grid and are carbon-neutral.
As one of the city’s major urban renewal projects, the Central Park towers in Sydney (bottom right) are integrated into the city’s current layout. The two residential buildings have living walls, which adjoin a public park and commercial space.
