Annex 55 Reliability of Energy Efficient Building Retrofitting – Probability Assessment of Performance & Cost (RAP-RETRO) ran from 2009 to 2013. The scope of the project was to develop and provide decision supporting data and tools for energy retrofitting measures.
The aim of the project was to develop knowledge and tools that support the use of probability based design strategies in retrofitting of buildings to ensure that the anticipated energy benefits can be realised. These will give reliable information about the true outcome of retrofitting measures regarding energy use, cost and functional performance. The tools were created by merging hygrothermal building physics with probability and economic analyses.
