BuildReUse ‐ 100 percent re‐use and recycling in buildings with short usage cycles
30 Months (1.2.2022 to 31.7.2024)
Starting point / motivation
Globally limited primary resources make re‐use necessary and sensible – also in the construction industry. Re‐use of building components protects ecosystems by reducing the use of primary resources, increases the resilience of the economy through independence from raw materials, and enables sustainable economic activity while saving landfill volumes. Currently, re‐use of building components such as beams, windows or suspended ceilings ‐ although technically possible ‐ still takes place very rarely. In some building types, such as supermarkets or office buildings, the effective service life of the entire building or of specific building components is relatively short: Effective service life often ranges from 3 to 15 years, as frequent adaptations to the respective use and high functionality are required. Here, re‐use has a particularly strong impact on the resource balance.
Contents and goals
The overall objective of the "BuildReUse" project is to develop basic principles for the construction and deconstruction of three building types with use cycles of about 10‐15 years, specifically for supermarkets, office buildings and interim sanitary buildings. These buildings could use re‐use components while still under construction, and should be fully demountable and thus re‐useable without significant energy expenditure.
Expected results / conclusions
An important goal of BuildReUse is to identify and develop implementation concepts for the re‐use of building components. Moreover, the BuildReUse team will conceptualize building development processes, cooperation models and business models that explicitly provide for and actively support re‐use in the construction industry. In order to consider re‐use in building footprints, an evaluation system that includes re‐use will be designed. Another planned result of BuildReUse is the definition of requirements for re‐use products and components in form of a BuildReUse guide or handbook, which is necessary for broad implementation.
