Appointed by real estate company Besix Red, we investigated the possibility of reusing more than 4.400 sqm of raised technical floor panels. The case was the renovation of a large office building in Luxemburg. The business as usual scenario planned to scrap all raised floors during strip out, to be replaced with new panels after the renovation. Points of attention for our study included the formaldehyde emissions of the material, and the mechanical deformation caused by wear. We concluded that in this case, despite the age of the building material, reuse on site after a total overhaul of the building is technically feasible for the majority of tiles, and represents a potential of over 45 ton of CO2 savings. The operation can be executed at no additional cost, and will likely even generate savings on the building economy.
