Occupant behaviour at the Presidential Palace of San Anton, Malta : a study supporting the development of a methodology to enhance energy efficiency in heritage buildings

Abstract

The eco-refurbishment of heritage buildings, which addresses energy efficiency, presents particular challenges to Euro-Mediterranean countries. This is compounded by sensitive adaptive reuse and occupant behaviour. This research seeks to develop a validated simulation model to profile the impact of proposed interventions and retrofitting solutions: an innovative assessment tool, enabling best practice decision-making, effective planning and optimal results in the drive towards maximising sustainability in historic buildings. The Presidential Palace of San Anton in Malta has been chosen as the case study. This national 17th century treasure represents a typology of heritage buildings, characterising the climatic and cultural profile of Mediterranean countries. Having undergone several transformations to accommodate its periodic reuse, the building is now an important multi-functional activity hub. This paper, which forms part of a wider study, will focus on the assessment occupant behaviour and comfort in this setting, an understanding of which is pivotal in identifying energy efficiency goals. The research will derive and test a methodology for examining users’ perception, and how the internal environment is adapted to meet comfort requirements and functionality: this through the use of semi-structured interviews with building occupants.
