Texas umbrage FYI, regarding the story “A Texas-sized Sprinkler Installation, (CSE 9/06, p. 50), I'd like to clarify that the largest university residential complex in the United States is the 1,093,468-sq.-ft. Joseph Ellicott Complex at the University at Buffalo, which houses approximately 3,300 residents.

Texas umbrage

FYI, regarding the story “A Texas-sized Sprinkler Installation, (CSE 9/06, p. 50), I'd like to clarify that the largest university residential complex in the United States is the 1,093,468-sq.-ft. Joseph Ellicott Complex at the University at Buffalo, which houses approximately 3,300 residents.

Everything is not always bigger in Texas!

More washer worries

The letters on the condensing dryers are quite interesting ( CSE 9/06, p. 11 ). My experience with a new installation in a serviced apartment in Australia is that the new dryer did do a better job drying the clothes; it only took two hours instead of the four hours in the previous apartment.

I did find, however, that the failure to exhaust the lint outside meant that we had more lint and hair left on the clothes. I wonder also whether that will translate into poorer IAQ for those sufferers of dust allergies.

Some Concerns about Selective Coordination

I just finished reading “A Critical look at Selective Coordination” by Jim Degnan (CSE 9/06, p. 21). I would like to point out a couple of code reference errors:

Beginning on page 21, the references to Sections 700.18 and 701.27 of the NEC are transposed. The correct section numbers are 700.27 and 701.18.

Additionally, on page 26, under “Proposal 13-159,” Section 701.27 is listed again and the correct section is 701.18.

Other than these errors, this was an excellent article.

Dale Sprague, P.E.Cincinnati

In reference to “A Critical Look at Selective Coordination,” Mr. Degnan brings forth a number of good points. However, he distances himself too far from the problem to be solved.

For instance, a fault in the fire pump room should be cleared—and resettable—in the pump room and not at an electrically upstream location that may very likely be on the other side of the fire.

The attainment of electrical coordination is always possible and thus is an economic decision.

R. Schneider, P.E.

Editor's note: We have another, longer response to Mr. Degman's selective coordination article, but due to space constraints and for an opportunity for Mr. Degman to reply, we will present the letter in next month.
