Educates AAMA Members on Life Cycle Assessment
June 2, 2009
Dan Handeen, research fellow at the University of Minnesota, who
does work regarding life cycle analysis (LCA), gave two presentations
to AAMA members meeting in Minneapolis this week with the goal of
educating them regarding LCA. Yesterday, Handeen spoke before members
of AAMA's Life Cycle Assessment Task Group and this morning he presented
to the Green and Sustainability Committee.
told members there are different levels to the LCA toolkit and different
models are available. Level 1 includes a product focus, level 2
an assembly focus and level three a whole building focus. There
are also different models available to conduct LCA (CLICK

Athena EcoCalculator which the USGBC will use in its LEED program.
(LCA has its own category within LEED.)
During yesterday's presentation to the LCA Task Group, Kerry Haglund
from the Center for Sustainable Building in Minneapolis, reported
that she is working with the WDMA and AAMA and other industry groups
to write a proposal in the hopes of getting stimulus money from
the Department of Energy to conduct LCA research.
But LCA is not an easy task. For example, Handeen pointed out that
when it comes to vinyl windows it would mean taking into account
the energy used by the crane to dig the tin. LCA would calculate
the impact of going all the way back to where the materials came
In yesterday's task group meeting, AAMA president Richard Walker
said the association's broad goal is to have its green certification
program that is under development (CLICK
HERE for that story) to be recognized by USGBC and "to
do that we need LCA." The group decided to continue looking
into fenestration-related North American LCA studies that the association
may be able to endorse.
