Here’s an innovative apartment building in Sri Lanka. It uses recycled water (including rainwater) to water the outdoor plants and flush toilets, and a solar panel to run the lobby lights and other shared resources.
When it’s completed in 2016 it will be the tallest residential vertical garden in the world, with planted terraces circling the entire structure. The 164 apartments, each with 2300 square-feet of floor space and an open feel, are designed to give residents a sense of ground-level living, as well as privacy and tranquility in a bustling city.
The planted terraces for each apartment will help absorb sound, provide shade, and cleanse the air. They’ll be automatically watered using a drip-irrigation system of rainwater, and along with recycled water to flush toilets, will help to reduce intake from the national water supply by an estimated 45 percent.
