MetroLivEnv aims to discuss the contributions of the metrology for the life cycle (design, development, use, demolition, recycling) of the living environment and the new opportunities offered by the living environment for the development of new measurement methods and apparatus. MetroLivE aims to gather people who work in developing instrumentation and measurement methods for the living environment at whole. Attention is paid, but not limited to, new technologies for metrology for: 1.Building diagnostic during and after constructions 2.IoT based monitoring systems 3.Measurements for BIM and digital twins 4.Indoor environmental quality 5.Sensors and sensor networks for smart buildings 6.Robots in living environment 7.Unmanned systems for living environment monitoring 8.Comfort and well being 9.Active and assisted living 10.Building energy performance assessment 11.Use of artificial intelligence for living environment measurements 12.Standards and norms 13. Uncertainty models
