Abstract:
An increase in high-rise building activity is apparent on a worldwide scale. However, this fast-pace development is not in tandem with today's environmental considerations towards reducing carbon emissions, mainly relating to building. The vast scale and energy demands of high-rises call for an in-depth study of this building typology towards improving energy efficiency. An important consideration in this process is the design of the building envelope as the mediator between interior and exterior conditions according to the climate and microclimate of the building's location.
Current architectural practices of fully glazed curtain wall envelopes make this relationship problematic, by resulting in high-energy loads for achieving thermal comfort. In recent years, a step forward towards energy efficiency is the implementation of a double-skin façade (DSF). Its application, however, is lacking consideration of the specific climatic conditions that will essentially result in an energy efficient design. This research studies a DSF envelope design for the high-rise building typology in Tel Aviv, Israel. Studies of glazed envelopes located in hot climates, become especially important due to the increased solar gains that enter the façade and lead to high cooling loads.
Optimum performance of the DSF for the hot and humid climate of Tel Aviv is achieved by alternating the double-skin envelope, between a closed and open DSF, through the presence of exterior windows. The outcome is a dynamic envelope design that alternates between open/closed DSF according to the temperatures that rise within the cavity. The results prompt for further studies for advancing the energy efficiency of the structure, with a focus on high cooling loads.
About the speaker:
Tanya Saroglou, PhD, is a qualified architect in the UK (ARB) and Greece (TEE), with experience in architectural design and project management. In 2003 she completed her diploma in architecture at Kingston University. In 2006, she was awarded the Professional Practice and Management in Architecture from the Bartlett, University College London, and in 2013 an MSc in Sustainable Design from the University of Edinburgh. She completed her PhD studies with Ben Gurion in Israel, via a thesis titled: Design Strategies Towards More Energy-Efficient High-Rise Buildings, and continues the research as a post-doctorate student in the Department of Structural Engineering. Her research so far has yielded three Q1 peer reviewed papers, two Q2, and five papers published in peer-reviewed conference proceedings.
