WP T3 Market developments for retrofitting existing buildings with straw insulation
From a sustainability perspective, retrofitting existing buildings is in general to prefer rather than tearing down and build anew. An exemplary evidence is shown in Table 1. More than that, 1 also real costs do reflect the advantage of retrofitting.
The author explains that these advantages become particularly clear if taking an LCA dimension into account and not focussing on a specific key target (like energy efficiency during operation of a building). Therefore, still from a sustainability perspective, building regulation and/or building policy must reflect a priority of retrofitting.
There is a relevant percentage of retrofitting in the building market in Belgium, the Netherlands, France, Germany and the UK.
