Dr. Bill Wolverton, a retired NASA scientist, found in his experiments that plants can remove up to 87% of the toxins in a room over 24 hours. All of the houseplants tested by Wolverton were able to remove formaldehyde, benzene and trichloroethylene. To clean the air in an average home or office, place one potted plant per 100 square feet of floor space. In commercial buildings, atriums of plants can help filter circulated air.

This represents a substantial drop in mortality compared to the previous five years, when winter losses of 29 to 36% had been reported. The unusually warm winter during 2011/2012 could be one possible contributing factor to the decline in colony losses, although no direct scientific investigation of the weather connection has been conducted.

The latest phase in this trend has been heralded by architecture firm Influx_Studio, who is looking at retrofitting buildings with green areas and sustainable technology to lower CO2 emissions. As part of a wider initiative called Decarbonize Chicago, the firm is looking at retrofitting the Marina City’s Tower in Chicago with a range of sustainable technologies, including farming areas, solar panels, wind farms, hydroponics bays and an algae bioreactor. The building hopes to take a three-pronged approach to tackling carbon emissions. Firstly, carbon will be directly taken from the air using the algae bioreactor. Secondly, CO2 will be absorbed by the algae and vertical farms as the plants grow. Finally, the other sustainable-energy technologies within the building with further reduce carbon emissions because less fossil fuel will be used to maintain the building. Each element not only reduces CO2 individually, but they also work together—for example, the wind turbines bring air into the algae system— to increase overall effectiveness.
