This paper describes the transitional zones of modern buildings and the impact of raising their temperature. A transitional zone is described as none steady-state spaces like entrance lobbies, corridors, lift-lobbies and landings, which allow occupants to transition through to more steady-state spaces. This paper presents the results of a dynamic simulation, where a typical case study building is used for an intervention of 1-5ºC increases in indoor temperature on energy demand. The results show raising the temperature in the transitional zones can result in a saving of 0.63% per ºC reduction of cooling for the whole building. The recommendation of this paper is to investigate a broadening of the thermal comfort parameters of these communal areas not serviced by the ASHRAE-55: 2-13, or any other standard, in order to identify the potential for reducing electricity used for cooling. Applying sensible engineering design load calculations will ensure comfort conditions and energy use are treated separately to occupied zones.
