The second lunch lecture of the year was given by Sweegers en de Bruijn on the 18th of December. Their lecture about the sustainable, energy neutral future of the built environment in 2050 was very insightful. The future of energy labels and possibilities to renovate existing (office) buildings proves to be a challenge for older buildings. Whether to demolish and rebuild or completely strip the building is dependent on the location of the building. We would like to thank Sweegers en de Bruijn for the lecture, and the members for their attendance! We hope to see you all on our next event!
