The document discusses strategies for improving urban and interior comfort through facade design. As the global population grows and urbanizes, living and working space for billions of additional people in cities will be needed by 2050. Facades must balance exterior demands like varying temperatures and interior needs including natural light, ventilation, and security. Both passive and active solutions are explored. Passive approaches include sound-absorbing facade units that can reduce noise levels. Active systems involve intelligent combinations of mechanics, electronics, and digital technologies, such as prototypes for acoustic windows with active noise control. The future of facades is framed as an important factor in sustainable, livable urban development.

…frequency dependent sound transmission calculation…
• The Digital Acoustics Lab (DAL) acoustics
software is a cloud-based software application.
• Developers, architects and clients can use it to
determine the effects of noise transmissions for
Schüco windows and façades, based on the
frequency.
• Sound simulation (auralisation) makes the result
audible.
• The different façade and glazing systems are
compared across the entire acoustic frequency
range.
