NEST Podcast: The Future of Construction
Episode 16: The future of concrete – with Holcim innovation strategist Simon Wiedemann
November 29, 2021 – Concrete is the most criticized building material, but also the most used. Simon Wiedemann, the guest of the 16th episode of the NEST podcast, operates in this area of tension. He has been working for Holcim for around 20 years and, in his current role as Head Solutions & Products, is responsible for shaping Holcim's global product portfolio in an innovative and sustainable way. In the conversation between Peter Richner and Simon Wiedemann, they talk about different ways of reducing the carbon footprint of concrete, the demand for more ideas from research – and how pilot projects can help to take off.
Episode 15: Blueprint for innovative building - with architect Silvan Oesterle
October 29, 2021 – In innovative building projects, the role of architects is central and enormously challenging - because they are the ones who pull all the strings. In the fifteenth episode of the NEST Podcast, Peter Richner talks to someone who knows this role inside out: Silvan Oesterle. He is co-founder of the architecture firm ROK, works as a lecturer at the Accademia di architettura di Mendrisio, and is the lead architect in the latest NEST unit STEP2 - which focuses on the marketability of innovations.
In their conversation, the two shed light on how architects can successfully integrate innovations into building projects, why they should no longer see themselves only as software users but also as software developers, and why architecture is "people business".
Episode 14: The aesthetics of PV modules – with designer Lynn Balli
September 22, 2021 – In February 2021, the Lucerne University of Applied Sciences and Arts, together with Empa, organized a design competition. The aim was to create PV modules as design objects. The designs were presented to the public and a jury. The winning project, named "Glasklar", now adorns the façade above the main entrance of the NEST building. In the latest episode of the NEST Podcast, Peter Richner talks to the textile design student whose design convinced the jury: Lynn Balli. In the conversation, the two shed light on how design can make renewable energies more attractive and promote them. In addition, Lynn Balli talks about the challenges she encountered in designing the material, which was rather unusual for her, and how she managed to breathe life into glass.
Episode 13: About life cycles in construction — with Professor Catherine De Wolf
Episode 12: CO2 law, what's next? — with Gian-Luca Lardi, president of the Master Builder's Association
June 25, 2021 – According to the Swiss Association of Master Builders, modern construction is the most important lever for climate protection because the Swiss building stock is responsible for 45 percent of energy consumption and 24 percent of CO2 emissions. The construction industry can therefore make an important contribution to energy efficiency and the reduction of CO2 emissions. In the twelfth episode of the NEST podcast, Peter Richner talks to Gian-Luca Lardi, President of the Swiss Association of Master Builders, about the CO2 law that was rejected by the Swiss voters, about why replacement buildings need equal rights to energy-efficient renovations, and what the "zero-risk devil" is all about.
Episode 11: The foundation for the next generation – with ETH Rector Sarah Springman
May 27, 2021 – 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.
Episode 10: Building with the big picture in mind – with architect and engineer Werner Sobek
April 27, 2021 – 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.
Episode 9: Wastewater as a resource – with environmental engineer Tove Larsen
March 25, 2021 – Turn old into new: Not only used materials can be recycled, but resources can also be recovered from wastewater.

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.
Episode 8: The virtuoso interaction of the different spheres of the National Councilor, researcher and entrepreneur Bastien Girod
March 1, 2021 – 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.
Episode 7: From dismantling to re-use with Kerstin Müller – a "hunter" for building components
January 29, 2021 – 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.
