construction elements and materials are reduced, and reused and recycled after the end of life
of the building. To reduce the volume of materials, enable the highest share of reuse of
construction elements, and improve the quality of recycling of construction elements and
materials, the knowledge of all materials used in the buildings is needed. Therefore, it is
necessary to develop a “material databank for buildings,” which gathers all information on
materials (origin, volume, environmental data, etc.) used in a building from construction to
disassembly. This will allow automized lifecycle assessments of buildings during the planning
phase and the optimization of design based on the assessment of materials used. The
information procured will also allow stakeholders to identify the “eco-friendliness” of the
buildings. In the long-run, the material databank of a building will become a part of the BIMtoolchain
dataset (see 3.1) and a certificate based on the eco-friendliness of the building and
the ability of reuse and recycling (circularity) will become a part of the TIR building certificate
(see 3.2).
4 Build up “Intencity” lighthouse projects
4.1 Technical: Demonstrate smart, green, and circular zero-energy districts
While the single technologies for TIR buildings, districts and cities are already available or under
development, the implementation of all technologies in one district or city with all crosslinkages
between the components of each of the three Internets – communication, energy, and
mobility – and the IoT platform is not yet operational. However, only the implementation of the
fully connected (sub) systems optimizes the aggregate efficiency and productivity gains that
comprise a Third Industrial Revolution paradigm shift.
Therefore, consideration should be given to erecting two fully-operational TIR lighthouse
districts in Luxembourg. One lighthouse project should be undertaken in a new Greenfield
district since many new districts will be built in the coming decades to accommodate the
population growth of Luxembourg. The other lighthouse project should be built out in an
existing brownfield district where the challenges and opportunities are quite distinct and
provide a different learning curve.
Moreover, the lighthouse projects should be embedded in mixed districts, which include
residential, non-residential, and industrial areas, to build up living districts, make full use of the
flexibility of the TIR infrastructure, and demonstrate synergy effects between the different
types of buildings. The development and implementation of the TIR lighthouse districts will
require the active involvement of all of the stakeholders: government (national and municipal),
relevant businesses (construction, mobility, ICT, trade, financing, etc.), social groups, and the
research sector. In addition, civil society organizations and residents of the districts should be
