Transitional zone design in the desert environment of Abu Dhabi: Vernacular vs. modern

This paper describes the transitional zones of vernacular and modern buildings in Abu Dhabi. A transitional zone is described as non steady-state spaces like entrance lobbies, corridors, lift-lobbies and landings, which allow occupants to transition through to more steady-state spaces. In particular, this paper draws from literature the effect vegetation-based microclimates may have on the vicinity of a dwelling, which may reduce the indoor cooling load. This study will involve a summary history of earlier transitional zones in vernacular architecture in Abu Dhabi, which uses little energy and purely by design, creates a comfortable environment. Passive designs in particular, allow a comfortable environment for occupants in high-heat desert conditions. This paper discusses the use of vernacular designs for present-day Abu Dhabi to create intermediate non-steady state spaces for relief from the heat. The Kansara Transitional Zone Survey was used to ask occupants (guests or otherwise) how their behaviour, comfort, satisfaction and productivity were affected in the transitional zones. The questions were asked upon immediate entry into the transitional zone. This paper discusses the format and content of the questions. The results of the survey are displayed followed by a discussion.
