The Ubakus U-Wert-Rechner is an online building-physics tool for analysing building components layer by layer. It supports calculation and visualisation of U-values, moisture-related aspects and thermal behaviour. Within EXCEL4HOUSING4.0 it can support practical training on energy-efficient renovation, insulation quality, thermal bridges, moisture risks and better decision-making in renovation works.
