Skycourts are recognised nowadays as essential transitional, movement and social interaction spaces in high-rise and mid-rise buildings. The paper reports on analytical research into the energy saving promising associated with modification of air movement strategy in skycourt zones. Heating and cooling in office buildings devour a high percentage of the overall energy consumption. Nevertheless, ventilation is addressed vastly according to cooling loads without considering its actual influence. The study aims to investigate the skycourt as a ventilated buffer space in high-rise office buildings and explore its impact on reducing energy demand for heating and cooling. Using a theoretical reference model of an office building in London, energy and CFD simulations are carried out over two modes; an air conditioning skycourt and a ventilated, unheated and uncooled skycourt. Results are compared with respect to energy reduction besides thermal comfort. Three spatial configurations of skycourt are investigated to define the optimal prototype of the skycourt in temperate climate exemplified by London.Overall, the simulation's results highlight that the incorporation of skycourt as a ventilated buffer zone reduces the annual heating and cooling demand remarkably. Furthermore, the comparison between the skycourt prototypes shows a variation in the energy performance of the building and the thermal conditions inside the skycourt.
