Thema: Renovation of existing buildings

7 posts

In addition to the use of wood and renewable building materials, an efficient way to decarbonise grey energy is to maintain the existing building stock and its shell construction for as long as possible. In order to use buildings permanently, adaptations, conversions or refurbishments are necessary from time to time. The way this is done can lead to significant differences in terms of life cycle assessment.

This list contains examples of refurbishments of existing buildings that have been carried out on a settlement or neighbourhood scale, taking further ecological and/or social aspects into account.
