Abstract

The objective of the present paper is to examine the environmental strategies applied in vernacular architecture. The study focuses on Greece, researching the contribution of open air and semi-sheltered spaces, such as loggias to the building’s overall comfort. The glazed hayat, an architectural element which is a later version of the ancient Greek loggia, will be studied. This architectural element provides passive solar heating during the winter, while it enhances cross ventilation and prevents overheating during the summer. In order to prove this environmental performance a monitoring has taken place in a number of traditional dwellings with a glazed hayat in the island of Lefkada during summer period. Moreover, a questionnaire regarding the annual performance of the dwellings presents the occupants’ perception and experience of thermal comfort. In this study the beneficial characteristics of the glazed hayat to the building’s thermal comfort are analyzed and presented.
