Never Stop Learning

This year as I watch my friends and family send their little ones off to school, I, too, am starting a new educational journey. I’m taking piano lessons. I’ve wanted to play since I was a child but never had the opportunity. My husband heard me talk about wanting to play a few times, so he suggested giving me lessons and a piano as a gift for our first wedding anniversary.

I literally thought about it for a full day. I was completely touched that my husband wanted to help me accomplish a lifelong dream. However, did I really want to commit myself to something completely out of the ordinary? I learned to play the trumpet in middle school and played through high school, so I can read music—treble clef. I’ve never had to learn bass clef or how to make my left hand and right hand play different music at the same time. Could I do it? What if I’m the worst adult student my teacher has ever had?

I came to the realization that the accomplishments of which I’m most proud pushed me out of my comfort zone. Plus, how could I possibly say no to my husband when his gesture was so sweet? I’ve had one lesson so far and the idea of being able to coordinate my hands still seems a little like being able to rub my stomach while patting my head. However, I’m excited about the future and am hoping I’ll be playing well by the holidays!

Every issue of Roofing has an educational bent, but this issue may push you out of your comfort zone. For example, cool roofs have been a hot topic for many years. Conventional wisdom states cool roofs are not appropriate for northern climates. Kurt Shickman, executive director of the Washington, D.C.-based Global Cool Cities Alliance, will challenge that notion in “Cool Roofing”. He presents new evidence from several scientific studies that demonstrate cool roofs provide benefits to buildings in Climate Zones 4 through 8.

Meanwhile, Thomas W. Hutchinson, AIA, FRCI, RRC, CSI, RRP, principal of Hutchinson Design Group Ltd., Barrington, Ill., and a member of Roofing’s editorial advisory board, shares his in-the-field experiences regularly. He notes in “From the Hutchinson Files” that code-mandated insulation thicknesses are forcing designers to take roof access door and clerestory sill details seriously. Hutch’s goal with his article is to give designers some confidence to create appropriate design and detailing solutions.

These articles may challenge what you’ve always done but they’re worth considering and discussing. In fact, I’d really like to hear what you think about them. In return, I’ll keep you updated on whether I’m becoming the next Chopin!

ERA Challenges LBNL Study about White Roofs

The Bethesda, Md.-based EPDM Roofing Association (ERA) is challenging a study released by Lawrence Berkeley National Laboratory, Berkeley, Calif., which cites white roofs as the most “cost-effective” roofing option over a 50-year time span. The study, published in the March 2014 issue of Energy and Buildings, also calls for the phase-out of black roofs.

“Our members make both black and white roofing membranes. We strongly oppose any recommendation that irresponsibly promotes the use of one of our products over another based on faulty science. We question the validity of this study since it is based on a sample size of only 22 roofs, and we are challenging the conclusions that the authors draw from the data,” says Ellen Thorp, ERA’s associate executive director. “Due to the complexity of roof and building science, prescriptive requirements that limit design choices are not in the best interests of architects, design professionals or building owners.”

To help provide clarity regarding roofing-system choice and refute some errors in the study, ERA convened a panel of experts to review the LBNL science and its conclusions. A complete analysis can be found on the ERA website.

Overall, the LBNL study was marked by “a systematic failure to understand that roofs are systems, not a single component,” says Thomas W. Hutchinson, AIA, FRCI, RRC, principal of Hutchinson Design Group Ltd., Barrington, Ill., an internationally recognized expert on roof system design and a Roofing editorial advisor. “Additionally, the study completely ignored
ballasted EPDM systems that, in other studies, have proven to be the roof system that provides the greatest service life and energy savings. To suggest that a comparatively ‘new’ roofing material will have a longer service life than EPDM, a material proven to last over 30 years, is naïve.”

“Our members—Firestone Building Products, Carlisle SynTec Systems and Johns Manville—have a vested interest in providing accurate information to our customers,” Thorp adds. “Their knowledge is based on marketing, installing and maintaining thousands of roofing systems. We hope that architects, specifiers and roofing consultants will continue to rely on their field-based knowledge about the comparative costs and effectiveness of roofing systems, rather than on flawed science based on flimsy and biased data.”

Benjamin Mandel, a research assistant in the Heat Island Group at LBNL and an author of the LBNL study, recently responded to ERA’s remarks on Today’s Facility Manager’s website.
