Nathan Mendes is currently a Full Professor and Director of Stricto Sensu Graduate Studies at the Pontifical Catholic University of Paraná (PUCPR), where he also coordinates the Institutional Project for Excellence in Stricto Sensu Education. He earned his PhD in Mechanical Engineering from the Federal University of Santa Catarina in 1997, having conducted part of his doctoral research at the Lawrence Berkeley National Laboratory (LBNL). In 2002, he received the CNPq Young Scientist Award and currently serves on the editorial boards of the Journal of Building Physics and the Journal of Building Performance Simulation. He holds patents and software registrations, including Domus, a simulation tool for hygrothermal and energy performance of buildings. Professor Mendes has actively contributed to the International Energy Agency (IEA), participating in Annexes 41, 55, 60, 86, and 97 ( 2025 - ). He also served as president of the Brazilian regional chapter of the International Building Performance Simulation Association (IBPSA) and is the national representative to IBPSA-World. His research in Mechanical Engineering focuses on energy, heat, and moisture transfer in porous building materials, the modeling and experimental analysis of HVAC systems, building energy efficiency, and the simulation of hygrothermal and energy performance in buildings and cities.
