What's the Word at Day 2 of BEC? Green, Green, Green
Yesterday was the second day of the Glass Association of North
America's 2007 Building Envelope Contractors (BEC) conference. Max
Perilstein, of Arch Aluminum & Glass, and chair of the BEC division
told attendees that there were 520 people taking part in the event.
If there had to be a key word to describe this year's conference,
it would have to be green, as the majority of presentations tied
in, some way, to energy-efficiency, green building design and LEED
One of yesterday's green presentation included a green panel discussion
led by Keith Boswell, an architect with Skidmore, Owings & Merrill
LLP, James Bogdan of PPG and Henry Taylor of Kawneer Co. Inc.
Boswell began the presentation with a discussion on the LEED costs
from the architectural and engineering side, and he should examples
of projects from his firm that have received LEED ratings.
"LEED is a holistic approach in the design phase," Boswell
said. "Our costs are mainly in the research that takes place
The examples he presented showed how elements such as light shelves
and sunshades had been used to earn LEED points. High-performance
glass, insulating glass units and double-glazed facades have also
Bogdan followed. He explained that the three areas in which glazing
can contribute to LEED are: optimizing energy efficiency; using
regional materials; and indoor environmental quality. He also noted
that the three major drains of energy are interior light, heating
and cooling. Products such as new low-E coatings can be used to
reduce these costs.
Taylor was the third panelist. He began with a few statistics. In
2006 the AIA set a goal to cut energy costs by 50 percent by 2010
and 90 percent by 2025.
"The costs of green are not that much, but the resulting benefits
can be great."
He talked some about the different areas and categories in which
LEED points are available for glass, and mentioned opportunities
for products such as photovoltaics. "This can be used in lieu
of spandrel; it can also be used in skylights," said Taylor.
"You can allow in the light and generate energy. It is a cost,
but a good cost for our industry."
He encouraged everyone to recommend and suggest these high-performance
products whenever they can.
"Five years ago they [architects, owners, etc.] would not have
listened to you because it cost more," Taylor said. "Today
they will listen to you. Do not be afraid to suggest a better product
because it costs more-they will listen."
Other green areas of discussion came from presentations on electronically
tintable glass, thermal requirements in curtainwall and insulating
