James O’Callaghan will describe the journey of transparency in the design of structural glass and chart its development over the last 20 years, highlighting the innovations that have led to increased transparency. Through a series of high-profile projects for Apple, he will illustrate how glass technology has evolved, including joining and glass dimensions, which in combination have led to incremental changes in the industry. While there has been a notable focus on increasing transparency in recent years, it is clear that this is now being challenged by the need to balance the energy equation. The desire for transparency and light in our buildings is often at odds with the need to limit solar energy gains and the associated energy demand to manage those gains.


James O’Callaghan is a world-leading structural engineer who is widely acknowledged as an authority on the use and design of structural glass. His innovative and practical approach has made him an integral part of the design team for a number of pioneering and award-winning projects for tech giant Apple, including the iconic glass stairs, bridges and facades in over 300 retail stores around the world, and he is listed on over 20 design patents. He is co-founder of the award-winning structural engineering practice Eckersley O’Callaghan and a professor of Architectural Glass at TU Delft. James has a key role in establishing research in all areas of glass in architecture.
