The incorporation of interior greenery has grown to the point where it now even takes up indoor wall spaces.
"A new trend sees ‘bio-walls’ offering bring new life into conventional spaces. According to former University of Guelph researcher Dr. Alan Darlington, the incorporation of these green walls are drastically increasingly Indoor Environmental Quality (IEQ) passively, without energy reliance."
“We’re getting rid of 60 to 70 per cent of the pollutants in the air after a single pass through the filtration system,” he said. “It means less fresh outdoor air has to be brought in to maintain air quality and that significantly reduces the energy required to heat or cool that air. It’s a really beautiful technology.”
