The significance of bioclimatic architecture has become widely accepted since the 19705 and the implementation of its principles in practice is a key factor in order to achieve energy efficiency in the building sector. The way, however, from scientific acceptance to commercial utilization is not a straightforward one. This paper deals with the notion of bioclimatic architecture in buildings and investigates the aspects of this concept in Hellas. A sample of university researchers, building contractors and members of public organisations was interviewed using a standardised set of guidelines. The barriers to promoting bioclimatic design, role of the local government in the adoption process, level of environmental culture as well as perspectives of this concept in Hellas were the key areas of discussion in each of the interviews. The results from the data analysis reveal insufficient economic incentives, a lack in technical information as well as a lack in specific environmental policies that would foster the propagation of bioclimatic architecture.
