Summary
Project logo NaVe
Many buildings can be renovated sustainably and without damage by retrofitting interior insulation, while at the same time improving thermal living comfort. These measures have a high energy-saving potential, which is still largely untapped. Depending on the type of building, transmission heat losses can be reduced by 50-80%, which opens up the possibility of a sensible use of environmental heat. In order to survive on the market, manufacturers are developing new insulation systems that are becoming increasingly efficient but also more complex. Professional planning will therefore place higher demands on both planners and planning tools in the future. Although simulation is already playing an important role in standards, there is a lack of generally binding regulations on how to perform verifications with regard to damage mechanisms (frost damage to masonry, metal corrosion in mineral building materials, damage and loss of strength of wood and wood-based materials, condensation on surfaces and boundary layers). Therefore, users are often overwhelmed with the interpretation of the simulation results. The aim of the project is therefore the development of scientific evaluation criteria and the implementation of a verification procedure. The aim is to achieve a technically flawless evaluation of critical structural details, to increase planning security across the board, and to build confidence in the sustainability of energy-related renovation measures.
