To keep the construction sector moving forward, the foundation laid by colleges and universities is crucial. They must respond to current trends and anticipate future developments in order to equip graduates with the necessary tools for their future careers. In the eleventh episode of the NEST Podcast, Peter Richner welcomes ETH Rector Sarah Springman. The two talk about the major challenges of the pandemic for universities, the importance of getting students excited about technical courses at an early age - and the surgeons of the underground.

Calling a spade a spade: That's the first step towards constructive problem solving – even when it comes to the sustainable use of resources and the resulting emissions in construction. In the tenth episode of the NEST podcast, Peter Richner welcomes architect Werner Sobek, a pioneer in sustainable building culture and a man of clear words. Together, the two take a look at the construction industry and beyond, pleading for honesty and transparency in thinking, speaking and acting – and defusing linguistic smoke petards in the process.

Turn old into new: Not only used materials can be recycled, but resources can also be recovered from wastewater. In the ninth episode of the NEST Podcast, Peter Richner talks with Tove Larsen, environmental engineer and member of Eawag's board of directors, about the impact of innovations in water supply and wastewater management. They speak about what valuable things we flush down the toilet, why problems should be solved directly at the source, and why wastewater does not lie.

In order to achieve the change towards a climate-friendly society, it is important that research, business and politics work closely together. In the eighth episode of the NEST Podcast, Peter Richner talks to someone who has been working for climate protection and sustainability in all three spheres for years: Bastien Girod. The two talk about the challenges for a researcher in politics, about the opportunities that arise when you master the keyboard of the different spheres – and about the danger that comes from sorcerer's apprentices.

Reusing building materials and entire building components is one possible approach to circular and resource-efficient construction. The architect Kerstin Müller of Baubüro in situ has been advocating this for years, has implemented several lighthouse projects, and is thus familiar with the challenges of re-use. In the 7th episode of our NEST podcast, Peter Richner talks to Kerstin Müller about the hunt for used materials, restrictive standards and laws – and about a dating platform for building components.

Fabio Gramazio is Professor of Architecture and Digital Fabrication at ETH Zurich and is one of the international pioneers of digital construction. Together with his partner Matthias Kohler, he was responsible for the architectural concept of NEST and was also significantly involved in the realization of DFAB HOUSE. In the fourth episode of the NEST podcast, Peter Richner talks to Fabio Gramazio about the resinous path towards a digital building culture, about the dangers of a revolution and the patience required for evolution – and about the complexity of trees.

Judit Solt is Editor-in-Chief of TEC21, the leading technical and scientific construction journal in the German-speaking part of Switzerland. As a graduate architect, she also works as a freelance architectural critic, writes articles for newspapers and books and is involved in competition juries and expert commissions. In addition, she is a board member of the "Haus der Farbe" school of design.

Damian Müller (FDP) has been representing the Canton of Lucerne in the Council of States since 2015 and is a member of the Environment, Spatial Planning and Energy Committees ESPEC. In his function, Müller played a key role in the total revision of the CO2 Act.

The SIA has over 16'000 members and represents the interests of architects and engineers in politics and society. The SIA is also known for its important body of standards. It develops, maintains and publishes numerous standards, regulations, guidelines, recommendations and documentation that are of vital importance for the Swiss construction industry. In the first episode of NEST Podcasts, Peter Richner talks to Stefan Cadosch about the tension between standardization and innovation, about hypes in architecture – and about expensive violins.
