It is more climate-friendly to restore or transform an older building than to construct a new building. That is an overall conclusion from the work of Realdania By & Byg after having restored or transformed around 60 historic buildings, and most recently completed life cycle assessments (LCA) of 50 of these projects.
Restoring a historic building is a balancing act under which preservation values, aesthetics, present use, finances, the climate and the environment have to be weighed against each other. In this context, LCAs can sharpen focus on the climate dimension by clarifying the total carbon emissions linked with restoration with the individual choices and with alternative to these.
In sections based on three interviews and eight specific cases, this publication
focusses on how LCA is used to analyse the climate footprint of restoration and transformation projects run by Realdania By & Byg, and how learning from this work can be included in new projects.
64 pages with many illustrations.
