List of air-filtering plants The first list of air-filtering plants was compiled by NASA as part of the NASA Clean Air Study,[1][2][3] which researched ways to clean air in space stations. As well as absorbing carbon dioxide and releasing oxygen, as all plants do, these plants also eliminate significant amounts of benzene, formaldehyde and/or trichloroethylene. The second and third list are from B. C. Wolverton's book[4] and paper[5] and focus on removal of specific chemicals. NASA researchers suggest efficient air cleaning is accomplished with at least one plant per 100 square feet of home or office space.[1] Plants[edit] Foliage[edit] Most of the plants on the list evolved in tropical or subtropical environments.

CELL Steel skin uses solar radiation to heat buildings Tata Steel has launched the Colorcoat Renew SC® integrated solar air heating system. The system incorporates the company’s micro-perforated Colorcoat Prisma® pre-finished steel as the solar collector, and is installed as an additional skin on a building’s wall, creating a cavity between it and the wall. Negative air pressure within the cavity draws in pre-heated boundary layer air through perforations in the transpired solar collector’s surface. Ten-year payback The company says that 1m2 of collector area can typically deliver 250kWh heat per year. Peter Wilks, marketing and sales director at Tata Steel, said: “Our latest products including Colorcoat Renew SC® are designed to harness energy, turning buildings into energy generators and bringing the goal of zero carbon buildings ever closer.’’ Before its launch to market, the product was applied to Tata Steel’s Sustainable Building Envelope Centre and to the Deeside Leisure Centre as part of its refurbishment.
