This book contains selected papers from the BuildSim-Nordic 2020 conference, October 13th & 14th 2020. The conference was hosted by OsloMet University in Oslo, Norway, and organized in cooperation between the Nordic chapter of IBPSA, OsloMet and NORVAC.

The BuildSim-Nordic 2020 conference is the first in a series of events with a long-term objective to establish a key biannual international conference in building performance simulation, with a strong focus on Nordic countries. The purpose is to create a platform for exchanging ideas, issues, and research findings that facilitates international collaboration and the meeting of minds between practitioners, researchers, and students.
