1) What percent of the exterior of a commercial (or architectural;
these names are often inter-changeable) building consists of glass?
(Glass, along with aluminum, brick, etc. I don't care what or about
the other materials, just the percent of glass.)
2) Has this percent increased or decreased in recent years?

Mikedriehorst,

Please take a look at the material below and let me know if this

Nick Limb, a partner with the research firm of Ducker Worldwide 
presented research concerning the percentage of glass used in the
exterior of different types of buildings.

? Basic retail stores use the most glass as a percentage of the
exterior surface?38 percent. Approximately 21 percent of the surface
area of offices and banks use glass. Use of glass was also tracked
along geographic lines, with the South using the highest percentage of
glass on building exteriors, and the Midwest using the lowest. ?The
largest single commercial glazing market is in the South,? Limb said.
Commercial glazing was also tracked by type. Thirty-six percent of
glass is used in new construction, 26 percent in additions and 38
percent in remodeling and/or replacement."

"Limb also made a number of predictions about the use of glass in the future. 

Among them:
- There will be tremendous growth in the value-added products;
- The use of glass in interiors continues to increase;
- Expect large increases in the use of decorative and privacy glasses;
annual growth of ten percent or more is possible;
- Variable climate-controlled glass will make strong headway;
- The use of low-emissivity glass will continue to grow; the
percentage of low-E glass that is sputter-coated will decrease. ?We
are only halfway through the adoption and use of low-E glass;?
-The float suppliers will continue to dominate in the coated glass arena;
- Contract glazing companies should expect to have seen an average
growth of 14 percent in 2000 and median growth of 10 percent;
- Contract glazing growth was slowest in the Midwest (a 7 percent
increase) and highest in the Northeast (15 percent).?

Bobbie7,
The first two sources don't really answer the question. It seems as if
I'd have to do the calculation myself and compare glass v. the other
materials; but then still not be sure enough to use it.

The third piece from Ducker's Nick Limb is on the money! Did you find
anything else from Ducker that gave more details of the research Limb
noted? Or, did you come across any similar glass industry research
that might be good?

If not, then I'll with go with what you found, and/or check the Ducker
Research site.
Mike

Hello again Mike,

Thank you for letting me know that the information I provided by Nick
Limb, of Ducker Research was satisfactory.


I have located additional material for you. 


From Glass Magazine: February 2004

Economic Outlook for the Industry

?Knowing what is ahead can help to lower risk and raise the odds of
success.  ?Business is looking to pick up and things are going to be
better for you,? Nick Limb, Ducker Research Co., told attendees at the
BEC Conference in Las Vegas. This doesn?t mean it is going to be
easier, he added, just that conditions are going to be better.

Limb pointed out that nonresidential construction has turned the
corner and the overall rate of decline is slowing.  Looking ahead, he
expects overall demand to pick up in the second half of this year.

Putting glass into perspective as a building material, Limb said
vision glass is 29 percent of total exterior wall area (the single
largest category), and spandrel glass is 1 percent. This is actually 1
percent higher for vision glass than a couple of decades ago, his
historic figures show.

Limb contrasted the opinions of contract glaziers and architects,
based on interviews his company held with each group last fall.

Contract glazing companies see more low-E/energy codes as the most
important industry trend (an overwhelming 60 percent) and more
laminated glass use as the second major factor(over 20 percent).

Architects also see energy efficiency/low-E as the most important
trend (at 30 percent) but for them this is followed by daylighting,
safety/security, and aesthetic issues (all close at 17/18 percent).?

Very satisfied. It wasn't perfect (5 stars), but is definitely
something I can use for the glass trends article I am working on for
an architectural magazine. Thank you very much for the information.
Definitely worth the price.
