Space heating accounts for more than 60 percent of the energy use of buildings in the U.K., the study noted, and buildings account for 17 percent of the country’s greenhouse gas emissions. The researchers said they hoped more buildings could add green walls to prevent heat loss, which would reduce heating costs and cut greenhouse gas emissions from energy used to power climate control systems in buildings.
“It’s that basic primeval connection with nature that you get, and you don’t get that with polystyrene, oddly enough.” You’ve got biodiversity, you’ve got improved visual amenity research has found that people feel happier about their environment or about their buildings if they are covered in plants,” he said. “That also brings with it all the added benefits. To improve heat retention, the cavity can be filled with insulation like plastic-based polystyrene, said Matthew Fox, an sustainable architecture researcher and an author on the study, but putting a green wall on the outside of the building could have the same effect.
are constructed with walls made of two layers of stone, with a hollow center.

Heat loss from an exterior wall covered with plants in a half-century-old building was 31 percent less than a wall without plants in the same building, according to the new study, from the University of Plymouth in the United Kingdom. Lamont said he felt an “almost childlike joy of discovering these bizarre new noises that a fish makes and we have never heard before,” he said, “and the thrill of swimming along listening to something that maybe nobody’s heard before.” SOLUTIONS Walls of Plants to Keep You WarmĬould a wall covered in plants work as an effective insulator for buildings? New research shows how powerful vertical gardens can be in keeping indoor temperatures comfortable. And by studying the sounds of a coral reef, he said, researchers can hear all kinds of animals that can’t be seen, whether they’re camouflaged, nocturnal or just well hidden. “That to us is an indication that a lot of the animals responsible for those sounds have come back to the restored reef and have colonized and set up shop.”įish and other marine creatures use sounds for hunting, mating, fighting and communicating every day, Lamont said. “There are all sorts of these noises and sounds and buzzes and pops and trills and croaks and groans,” said lead author Tim Lamont, a marine biologist at the University of Exeter.
The diversity of sounds was similar at healthy and restored reefs, they reported this week in the Journal of Applied Ecology. The investigators set up underwater microphones to monitor the soundscape on healthy, degraded and restored reefs. Researchers at the University of Exeter in the United Kingdom sought to find out whether reefs in Indonesia that were restored after being destroyed by dynamite had recovered their sound, as well as their healthy appearance. But around parts of the reef where coral has been violently destroyed by dynamite fishing, the waters are silent. Fish whoop, purr and grunt while shrimp snap.
