Abstract: Costs prediction throughout the life cycle of building projects is supported by the life-cycle-
cost (LCC) concept. The end of life stage of a building facility starts when the building or part

of it is decommissioned. At this point, the cost of demolition/deconstruction may be considered
as a multioutput process that provides a source of materials, products and elements that shall be
reused, recovered, recycled or disposed. These processes should be economically and
technically viable. Activities such as deconstruction, transport and waste processing still face
difficulties regarding the costs estimation and time ratios. Databases with the adequate quantity
and quality of economic information as well as data structures with formats that facilitate
comparison and extrapolation is needed.
This paper addresses these problems and proposes a standardized structure for economic data
collection for the end of life stage of buildings. A case study based on historical data of public
school buildings refurbished in Portugal during the 2000s is presented. It shows the potential
application of the proposed structure and aims to define end-of-life indicators that promote the
circular economy through LCC-informed decisions in the building sector.
