Adrian Roiz, Arup, Title: Circularity & Sustainability above and beyond the ideal world: a few practical notes and an example
He is an Structural Engineer by training, and joined Arup in 2006. In these 18 years, he has been involved in a wide range of projects in 5 continents, of different scales and including a variety of façade typologies, materials and systems: from standard curtain walling to geometrically complex structural glass, from commercial buildings to stadiums and airport terminal buildings. His approach to projects is defined by three key drivers: integration of complementary disciplines, technical acumen and sustainability.
Adrián led the engineering scope within the Arup team working on the envelope for the Real Madrid stadium full refurbishment, and is the key account manager for the Spanish giant fashion retailer Inditex. He has been for several years the chairman of the Spanish mirror committee of AEN/CTN-140/GT3.
Andreas Haug, baubüro in situ ag, Title: New and Improved: Re-use in Façade Construction
Andreas Haug graduated from ETH Zurich in 2005 and entered the world of construction before his studies by planning and building a climbing center himself. After completing his training, he worked as a freelance architect and as a project manager in various offices in Zurich and Lucerne. He focused on timber construction and housing, working on projects ranging from the renovation of old buildings to large-scale residential developments. He supplemented his office work with assignments on construction sites - most recently in a carpentry workshop - and lectures (e.g. on communal forms of housing). Andreas Haug has been working as a project manager at the in situ construction office in Zurich since 2018 and has been a member of the management team since 2023.
Basil Rudolf, baubüro in situ ag, Title: New and Improved: Re-use in Façade Construction
Rudolf Basil started out in the construction industry with his apprenticeship as a metalworker. After his years as a craftsman, he remained loyal to metal, but switched from the trades to the office when he started studying engineering. After several specialised years working as a research assistant at Lucerne University of Applied Sciences and Arts and at companies (Skyframe, Amstein+Walthert), he gained experience in the development, testing and certification of window and glazing systems. In his search for sustainable constructions, material diversity and instruments for ecological assessment, he then ended up in building physics. He has been working for Zirkular in Zurich since 2021.

Ron Jacobs, Jansen AG, Title: Reversible façades
Ron Jacobs (Amsterdam 1965) is Project Sales Manager International and has been working for Jansen AG for thirty years. After completing his studies at the Hogeschool van Amsterdam, he settled in Belgium in 1994 and became directly involved in the construction industry there. Active until 2021 as Jansen's distribution partner in the Netherlands and Belgium, Ron built a large network of construction professionals from all disciplines; from design, construction to maintenance. Reuse may be added to that. Since January 2022, he has been committed to promoting the unique properties of steel façade systems to architects, clients and universities on an international scale. Research plays a major role in the further international expansion of the Jansen brand. The LCA and related reuse potential of steel is of such significance that Ron has become closely involved in several international (research) projects and case studies. Architects and building professionals know Jansen references such as the award-winning Battersea Power Station in London, Depot Boijmans van Beuningen in Rotterdam and Gare Maritime in Brussels. Renovations and transformations of existing buildings have now become commonplace. Architects will increasingly repurpose and reuse existing buildings (adaptive re-use). So let us design the new buildings we build today fit for re-use in the future.
Jansen AG - Jansen Steel Systems develops and produces sophisticated architectural steel systems for windows, doors, and facades. Create unique structures with us.
