About SIRCULAR
SIRCULAR is committed to creating digital tools, technological solutions, and services to drive the decarbonisation of the built environment. The project aims to develop a methodology for assessing the circularity of buildings, which will evaluate the impact of new construction technologies in demonstration projects. These solutions will be accessible to both non-experts and construction professionals, allowing for easier access to information on decarbonisation and tools to improve circularity.
Information about our demo:
The demo building of the German regional cluster is part of the Karlsruhe Institute of Technology campus in the South of Germany and is used by the Department of Structural Engineering. It was constructed in 1970 and has never been renovated. Therefore, its energy efficiency proves to be insufficient according to current standards.
The building has 9 floors above and one below ground. It covers a total area of 9.780 qm, with a usable area of 5.070 qm. The structural system consists of a reinforced concrete skeleton construction, while the non-load bearing façade is made of concrete and glass elements. The construction follows conventional construction methods. As a result, it offers great potential for replication.
Goal:
In the scope of the SIRCULAR project, KIT together with ZRS will develop a holistic renovation strategy based on reused, recycled and natural building materials to achieve ZEB standard. More specifically, in this demonstrator, the developed SIRCULAR approach will be tested regarding its replicability for non-residential buildings. The partners will create a deep renovation plan consisting of a detailed building survey, an innovative waste wood harvesting and processing strategy and the construction of a new zero-carbon timber façade and roof for the building, supported by LCA/LCC calculations. The main aim here will be to follow principles of circular construction to enable multiple life cycles and to avoid construction as well as demolition waste. The building elements will be fully prefabricated in order to minimize construction time and costs. In line with the holistic design approach, aspects such as user comfort and health, sustainability, social and economic aspects will be considered throughout the entire design process.
