The National University of Singapore’s extension for the School of Design & Environment exemplifies a paradigm shift for comfortable and energy-efficient design in the tropics. The 91,500 sq. ft and 5-story building accommodate labs, design studios, and workshops for the schools of architecture and interior, landscape and product design. Transsolar Klima Engineering—an international climate-engineering firm that approaches sustainability through innovative climate and energy concepts for buildings- guided and supported the design team with simulation tools for thermal comfort, daylight, glare, and energy as well as with measurements of thermal comfort. In this webinar, Mr. Wolfgang Kessling, one of the directors at Transsolar KlimaEngineering, who has been instrumental in spearheading the energy concepts of prominent projects, shared his strategies, approach and insights for the SDE4 project.
