Indoor plants recommended by architects to cool homes

Architects are increasingly recommending the use of indoor plants as a biological mechanism to reduce home temperatures without relying solely on air conditioning. This cooling effect is driven by evapotranspiration, a process where plants absorb water through their roots and release it as vapor through their leaves.

For those with limited space, several small-scale plant options are available. Species such as Soleirolia soleirolii, orchids, and Hoya kerrii are suitable for small apartments or shelves. Other notable options include Echeveria succulents, Pilea peperomioides, and Fittonia. When selecting plants, it is important to consider light requirements, humidity, and pet safety; for instance, the Hoya kerrii is classified as non-toxic to dogs, cats, and horses by the ASPCA.
