Energy-Efficient Retrofit of Buildings by Interior Insulation

Thomas Stahl earned his MS degree in building physics and engineering from the University of Applied Sciences in Stuttgart and his second MS degree in building refurbishment from the University of Weimar. He has longtime working experience in the Building Science and Technology Laboratory of the Swiss Federal Laboratories for Materials Science and Technology (Empa) as building physicist and material developer (aerogel insulation plaster, moisture buffering plaster). From 2014 to 2019 he has been engaged in the development of innovative building materials in the R&D of Swiss Industrial companies serving as research team leader and managing director. Since 2016, he is co-founder and managing director of the Institute for Applied Building Physics (IABP) in Winterthur, Switzerland. Thomas Stahl is leading a working group within the International Association for Science and Technology of Building Maintenance and Monuments Preservation (WTA) and author of numerous publications in national and international journals. Karim Ghazi Wakili obtained his MS degree in experimental physics as well as his PhD from the Swiss Federal Institute of Technology (ETHZ) in Zurich Switzerland. He joined the Swiss Federal Laboratories for Materials Science and Technology (Empa) as member of the scientific staff, group leader and finally Senior Scientist in the former Laboratory for Building Physics where he served over a total period of 26 years. Since 2016 he is co-founder and managing director of the Institute for Applied Building Physics (IABP) in Winterthur Switzerland and has also a partial affiliation with the Bern University of Applied Sciences.His area of research and expertise includes heat and mass transfer in porous building materials at ambient and fire temperatures as well as the corresponding numerical simulations and experimental techniques. He is member of the editorial board of “Energy and Buildings”, “Advances in Building Energy Research” and “Buildings”.
