categorization scheme was ultimately
selected to increase the field of study to
include the impact categories of ozone
depletion, global warming, acidification,
eutrophication and smog formation. To
address the LCA data need, the team
partnered with thinkstep, the makers of
the GaBi LCA database and software, in
order to generate a custom, cloud-hosted
LCA database that could be easily updated
and maintained.
With Tally, KieranTimberlake
successfully integrates life-cycle thinking
into its design workflows. For example, in
the early stages of designing a structural
system for the Brown University School
of Engineering, KieranTimberlake used
Revit ® to model two primary structural
bay options presented by the structural
engineers, one made of steel and one of
concrete. The designers then used Tally to
analyze the environmental impacts of each
of the structural options. This small amount
of modeling gave the team actionable
LCA data with a quick turnaround time
and started a conversation about the
importance of reducing cement content
in the concrete mix, even in a steel-based
structure.
Later in the design process, the team
leveraged the design option capability
in Revit® to quickly compare two façade
assembly options. The analysis revealed
that a large proportion of the environmental
impact of the façade was in the insulation
products. An additional LCA comparison

allowed the design team to select an
alternative material with a lower impact profile.
Using these methods, the team was able to
produce a building with the same energy model
results, outward appearance and cost, but with
a dramatically lower LCA impact. The firm's
experience with this project demonstrated the
power of utilizing rapid LCA and the importance
of understanding material impacts.
Since its commercial release in 2014, Tally
has been integrated into the curriculum of
more than 50 universities around the world
and the design processes of hundreds of
architecture and engineering firms. Tally allows
architects to move from typologies and "rule of
thumb" calculations of environmental impact
to real-time assessments at pivotal moments.
With the access to LCA data that Tally provides,
practitioners and academics can move the
profession toward a more inclusive definition of
building performance.

ABOUT THE AUTHOR
Roderick Bates is an Associate and
Senior Researcher, Environmental
Management and Commercialization
at KieranTimberlake. His work is
focused on bringing real-world data in
line with the design process. Following
an initiative to quantify the embodied
energy of buildings-an effort that
was recognized in 2008 by the EPA
Lifecycle Building Challenge award
and a poster presentation in the 2009
ASHRAE Net Zero Energy Building
conference, Roderick worked with the
research group to develop Tally™, an
application for Revit that provides
accurate life-cycle data and reporting
tools to designers. Roderick interprets
ecological, economic, climate, social
and site data to inform sustainable
building design.
