In climates where external conditions are extremely harsh (e.g. Delhi in summers at 45°C) what is an occupant’s experience while moving form internal to external environments? How can we minimise the difference between extreme outdoor temperature and the desired indoor temperature? To protect occupants from thermal shocks and create opportunities for social interaction in a thermally comfortable environment, the need for a transition space that acts as a buffer between the external and internal spaces becomes essential. It regulates airflow and decreases direct and diffused radiations on the façade, hence reducing heating/cooling energy demands. Over the years ZedLab has experimented with transition spaces in different kinds of projects ranging from residential to institutional. Contrary to the traditional courtyard within the building envelope, the approach is to introduce transition spaces at the periphery that creates a protected external environment for the users and the building itself.
