CHALLENGES FOR THE USE OF LIFE CYCLE ASSESSMENT AS A DECISION-MAKING TOOL IN BUILDING DESIGN – THE WÄLLUDEN CASE STUDY

Abstract


The construction sector accounts for almost twenty percent of the global
carbon emissions, so measures to decrease the carbon footprint of
constructions should be introduced during design. A full LCA was
conducted for eight different designs for a four-storey multi-family building.
The methodology was tailored for a designer’s perspective to identify
challenges for the use of LCA by non-practitioners. Results show that the
selection of building system does not influence the results, as does the use
phase energy efficiency or the selection of materials. The production phase
becomes more influential with increased use phase energy efficiency.
Results suggest that either an increased knowledge of sustainability tools
among designers or further simplification of the tools, standards and guides
available is required.
