Abstrakt: AbstractThis paper reports on the development of an organic air cleaner (OAC), an interior architectural element that optimises plants’ CO2absorption in nonventilated air-conditioned rooms. Sansevieria trifasciata, Dracaena sanderiana, Scindapsus aureus and Syngonium podophyllumwere explored. Two methods were adopted: the plants’ CO2uptake was measured, and the results were used for the computer simulation inputs. An OAC works automatically by exposing the plants to indoor or outdoor air when the plants are in, consecutively, CO2absorbtion or emission phase. Computer simulations found that the most efficient placement for OACs to absorb CO2is to put them far from ACs.
