B uildings made of additively manufactured (AM) components are likely
to have higher energy efficiency and environmental sustainability than
conventionally manufactured (CM) buildings. AM building components can
be highly customizable and produced with less material. Given the continued
development of AM and CM technologies, many markets and the use scenarios
of buildings that prioritize different performance criteria, building components
will likely be produced with a mix of AM and CM technologies for the foreseeable
future. However, since building professionals are not informed about the value
of AM through transparent metrics like cost and environmental impact they
are unable to make well-informed decisions about the application of AM in
the building sector. Case studies of two AM metallic building components, a
large window frame and a bracket, carried out by the authors in collaboration
with a global building façade contractor demonstrated that AM for building
components is technologically feasible and can lower environmental impact
by up to 87%, but is cost-prohibitive today; in some cases, the manufacturing
cost and schedule were about 90% higher and 91% longer respectively. Based on
the case studies, a 19 step assessment method was developed with the aim to
allow building professionals to rapidly and consistently assess the applicability
(A), schedule (S), environmental impact (E), and cost (C) of producing building
components with AM vs. CM. The formal, partially automated application of the
method showed that it reduces the effort required for the ASEC analyses by
97% and improves the consistency of the A, S, and C analyses. However, it did
not improve the consistency of the environmental impact (E) analysis due to the
inherent flexibility of the life cycle assessment (LCA) method standardized by
ISO14040. Future work includes fuller automation of the method and extension
of this approach to other industry sectors.
Biography
Natasa Mrazovic, M Arch Eng, MCE, completed her PhD at
the Civil and Environmental Engineering Department (CEE),
Stanford University with a focus on Sustainable Design and
Construction, specifically the implementation of additive
manufacturing technologies popularly known as 3D printing,
into the Architecture-Engineering-Construction industry.
The title of her thesis is Assessment Framework for Additive
Manufacturing Technologies in the AEC Industry. During her
PhD studies at Stanford, she was a Research Assistant at
the Center for Integrated Facility Engineering (CIFE) at CEE,
Stanford University, an affiliate in the Simulation Research
Group in the Environmental Energy Technologies Division
(EETD) at Lawrence Berkeley National Laboratory (LBNL),
US and a Visiting Doctoral Researcher at the Additive
Manufacturing and 3D Printing Research Group, University of
Nottingham, UK. In her 10-year long professional career as an
Architect, Chief Designer, and Project Manager, she worked on
large-scale projects in Eastern Europe and managed her own
architectural office.
