 Because of the high wind areas in coastal South Carolina, the design for the new John Paul II Catholic School in Bluffton, SC centered on utilization of Petersen Tite-Loc Plus panels.  In addition to the panel’s proven ability with high wind testing, Miami-Dade testing of the Tite-Loc Plus panel was in place.

 The new high school serves families throughout the quickly growing Low Country Deanery, which stretches from Hilton Head Island to Walterboro and includes about 8,100 Catholics. Ultimately, about 500 students will attend the school. The school is open to students of all faiths and emphasizes technology along with a college preparatory curriculum.

“This has been in the works for 10 years,” said Ross Kuykendall, head of the school’s facilities committee. Kuykendall said the school, designed by Charleston architectural firm LS3P, has 14 classrooms and four other teaching spaces. The classrooms have partition walls that can be removed to create a flexible environment for teachers.

The building incorporates a combined 23,000 square feet of Petersen Aluminum’s Tite-Loc Plus panels in slate grey with striations. Installation was done by Southern Roof & Wood Care, Hardeeville, SC. The company specializes in metal panel roofing systems in the states of Georgia and South Carolina.

The first phase of construction was a two-story, 28,000-square-foot building and an all-purpose athletics field. Eventually, that building will house the high school, and other buildings will be added for middle school students, along with playing fields and a gymnasium

Roofing distributor for the project was CRS: Commercial Roofing Specialties of Savannah, GA.  Petersen Aluminum metal panels for the project were manufactured in PAC’s Acworth, GA plant.

Diamond State Dentistry of Milford, Delaware had outgrown their original office after less than ten years in business.  Owner Lucinda K. Bunting decided it was time to expand.

 

Because of the office’s rapid growth, general contractor for the project, The Whayland Company, LLC of Laurel, DE, planned the new building to allow for additional expansion as the practice continued to grow.

 

Tao Architecture & Design of Moorestown, NJ designed the 5,200 square foot state-of-the-art building.  Roofing panels for the building were installed by roofing contractor Quality Exteriors, Inc. of Harrington, DE, a full service roofing contractor with over twenty years of experience installing standing seam metal roofing systems for Peterson Aluminum.

 

“The new space has twelve treatment rooms, and our old location only had six, so this doubles our capacity,” Dr. Bunting explained. “When we had twelve women working the old office, it got just a little bit crowded.”

 

Aluminum metal panels for the project were manufactured in PAC’s Annapolis Junction plant. The building’s roof incorporates 8,500 square feet of Petersen Aluminum’s 24 gauge Tite-Loc Panels in Cityscape gray. Annapolis Junction personnel assisted with the selection of the panel profile and color.

 

Dr. Bunting hopes to bring her trademark wooden tooth to the new building. The wooden tooth sits outside of the old office and is beginning to show some wear and tear. Dr. Bunting is afraid it may not survive the move. “It is starting to show some weather damage, and has a few holes in it. Maybe I should give it a few fillings,” Dr. Bunting joked.

 The Metropolitan Government of Nashville and Davidson County undertook an aggressive plan to replace six aging fire stations and provide more functional and energy efficient buildings to better serve the community.  The six stations are seeking or have received LEED certification and all were clad with Petersen’s Snap-Clad aluminum panels.

 

The stations were design/build projects under the direction of Messer Construction Company, Nashville, as construction manager.

 

The installation of PAC-CLAD roofs on all six stations was done by Donelson Roofing Company, Mt. Juliet, TN.  Two of the stations—#30 in Joelton and #31 in Madison—are 15,000 sq. ft. facilities and were designed by Thomas, Miller & Partners, Nashville. The firm also designed one of the other six new stations.

 

The Joelton station and the Madison station each utilized approximately 20,000 sq. ft. of 16” Snap-Clad aluminum panels finished in Champagne Metallic.

 

The stations are located in residential areas and the goal was to make them fit in with the residential fabric of the area.  “That was the biggest influence in their design,” according to Jeff Earwood, project manager at Thomas, Miller & Partners.  “The hips and gables and dormers really respond to the residential areas.”

 

The Metropolitan Government of Nashville and Davidson County, owner of the stations, specified metal as the roofing material due to its longevity and low maintenance.  The Madison station has earned LEED Gold certification and the Joelton station is pursuing LEED Silver.

 

“The goal was to make the stations 50-year-plus buildings,” Earwood said.  “The use of quality materials and systems plus reputable manufacturers and installers was critical.  We had used Petersen on a previous fire station job and had good results.  They have a great reputation and live up to it.”

 

The installer of the Petersen roofs, Donelson Roofing, has considerable experience with PAC-CLAD systems.  “These were pretty straight-forward applications,” said Michael Smith, estimator and co-project manager at Donelson.  “The smallest of the six stations used about 14,000 sq. ft. of PAC-CLAD material and the largest about 20,000 sq. ft.  We did have some fairly long panels on the Joelton station–up to 60 ft.  But our crews are accustomed to that.”

 


Whenever the subject of cool roofing or energy savings comes up, the next topic is usually Heating or Cooling Degree Days, and there seems to be a lot of confusion about what these mean.  It’s tempting to think that a Heating Degree Day is a day on which you need to turn on the heat, and a Cooling Degree Day is a day on which you need to turn on the air conditioning, but that is not the case.

So let me dive right in:  a heating degree day is a way of summarizing the annual heating (or cooling, in the case of Cooling Degree Days) requirements in a particular climate.  This is a complex sounding concept that is actually quite simple.  On a heating degree day (HDD), the temperature falls below a standard “comfortable” temperature (usually 65° F) so a building or home needs to be heated to maintain the target temperature; and a cooling degree day is one where the temperature is above that target, requiring cooling.  Turning climate data into a heating degree day or cooling degree day is a matter of simple math.  If the average temperature on a given day is 80°F, the building needs to be cooled 15°F to reach the target 65°F.  That day would be counted as 15 cooling degree days (CDD). 

Another example: consider a typical New York City winter day with high of 40°F and low of 30°F, for an average temperature of 35°F.  This one day would generate 65 – 35 = 30 Heating Degree Days.  A month of similar days would accumulate 900 Heating Degree Days, which gives you an idea how HDD can be added over periods of time to provide a rough estimate of seasonal heating requirements. In the course of a heating season, for example, the number of HDD for New York City is 5,050 whereas that for Barrow, Alaska is 19,990.  Barrow doesn’t have any more days in the year, it just has lower average temperatures!

Average daily temperatures tend to vary farther to the low side, particularly overnight.  Because of this effect, it is common even for warmer climates to have more HDD than CDD.  Some would argue that in any climate where HDD exceeds CDD, a cool roof does not make sense, but that is not correct.  That’s because building occupants and services generate internal heat, and with conventional equipment, cooling is generally more expensive than heating.

There are a number of online resources where you can find heating and cooling degree data for climate stations around the country.  Or, you can just log into the free GAF Cool Roof Energy Savings Tool (“CREST”), which taps into HDD and CDD data for you automatically and helps you compare roofing assemblies to better determine what is right for your project.   

Does this topic of HDDs and CDDs generate questions in your business?  I’d love to hear – post in the comments below.

mike-petersenGreetings from Chicago (aka “Chi-beria”) where in the last month on at least one day it was colder than the South Pole! Construction just doesn’t happen when it’s that cold. Nevertheless, Spring is just around the corner and once this snow melts there ought to be plenty of new work for those of us in the metal construction market.

At Petersen, we continue to invest in new capacity. The recent addition of new Redbud slitters at both our Tyler, Texas and Acworth, Georgia plants will speed up our production and greatly enhance our ability to service the growing slit coil market necessary for on-site rollforming. We continue to add colors to our 20” coil program in support of this growing market.

Our PAC-CLAD color chart now includes 32 standard colors and six PAC-CLAD Metallic finishes. Standard substrates include galvanized steel, galvalume and aluminum. Given this combination of colors and substrates, I dare say we offer the building design community the broadest selection of architectural metal products in the industry.

Finally, our new PAC app for the IPad is now available for free download at the Apple App Store. The PAC App is also available for Android at Google Play. The App features information on all our roofing and wall products including complete detail drawings for each product. Once installed, you can use it anywhere, no internet connection needed. Download your copy today.

We look forward to working with you on your metal requirements as the year unfolds.

Informally dubbed “The Building in the Trees,” the new three-story Georgia Southern University Biological Sciences Building has more than 158,000 gross square feet that houses five active-learning classrooms, 10 teaching labs and 15 research labs utilized by more than 1,300 undergraduate and graduate biology students. The new facility is in a heavily wooded area. General contractor for the project, Brasfield & Gorrie of Kennesaw, GA, cleared a minimal number of trees so that students walk in the woods before they walk through the doors.

Complimentary panel colors were chosen for the natural setting.  The building’s roof incorporates 65,000 square feet of Petersen Aluminum’s 22 gauge Tite-Loc Plus in slate gray, and more than 30,000 square feet of Petersen M-36 panels were used for siding.

The siding panels incorporated both regular rolled charcoal (ribs out), and reverse-rolled silver. The architect, S/L/A/M Collaborative in Atlanta, chose to have the silver panels reverse-rolled (ribs in) to create a wider-looking flat panel.

Roofing panels were installed by Richter Contracting Company, Albany, GA. Siding panels were installed by Pierre Construction Group, Stone Mountain, GA. Both roofing and siding were supplied to these contractors by CRS: Commercial Roofing Specialties, College Park, GA.

Steve Vives, Ph.D., chair of the Biology Department, said the University’s goal is to make the building LEED Silver-certified and to use that certification as a teaching opportunity as well. “Those green aspects of the building are going to be advertised in the building,” he said. “We’re going to have some displays of power usage and water usage in real time so that other classes as well as ours can come in and actually use our building as a learning experience.”

Georgia Southern University, a Carnegie Doctoral/Research University founded in 1906, offers 125 degree programs serving more than 20,000 students. Aluminum metal panels for the project were manufactured in PAC’s Acworth, GA plant.


Casino D-7 Casino D-11b Casino D-9

The new D Casino Hotel in downtown Las Vegas is the result of a major renovation and renaming of the old Fitzgeralds Casino at the eastern end of the Freemont Street Experience, a canopied pedestrian mall and entertainment attraction.  The unique two-level casino offers a high-energy environment on the first floor and a retro, old-school Vegas experience on the second floor.
 
The D stands for “downtown” and is also a reference to the nickname of the property’s majority owner, Derek Stevens.  The owners completed a $22 million renovation and modernization of the 34 story hotel and casino.
 
The design for the main entrance incorporates approximately 2,000 sq. ft. of PAC-CLAD Flush Panels in a bold application.  The 12”, 24 gauge panels were finished in Matte Black and offer a strong contrast to the brightly illuminated “D” signage that marks the entrance.  The 28’ panels were installed in a segmented radius application as an integral part of the signage design concept.  The panels were fabricated with stiffening beads which Petersen recommends for longer panel lengths.  In addition, 600 sq. ft. of PAC-CLAD flat stock were used for flashing and trim.
 
Installation of the PAC-CLAD material was done by A.R.J. Incorporated, Las Vegas.  According to Andy Russo, Jr., owner, “The flush panels were a key component of the sign feature.  The large, illuminated D really pops out of the Matte Black panels.”
 
A.R.J. does a considerable amount of casino work in Las Vegas and has been using PAC-CLAD products for more than 20 years.  “The name of the game here is on-time delivery,” Russo said.  “With casinos, everything is a push.  They believe customers won’t come into a place that appears to be under construction.  So they want things done fast with no delays.  Petersen has always been great about reliable delivery.”
In order to minimize disruption, the majority of the installation work was done between 2:00 a.m. and noon.  “The site was a challenge because we had to work around the structures used in the Freemont Street Experience including large, overhead speakers and a zipline,” according to Russo.  “And with the long panels, we were working 50’ in the air.  But the job turned out great.  It delivers a great look in a very competitive environment.”
 
Design for the project was provided by Gensler, Las Vegas.


Ventless Clothes Dryer?

Clothes dryers use an intense amount of energy.  In fact, dryers use about 6% of all US electricity and  that number hasn’t been improving.

Plus, living here in the cold northeast like I do, it sure seems a shame to vent all that heated air outside, as conventional dryers do.  Regular readers of my blog will remember that I made a dryer vent box which we only attach in the winter.  It captures the heat (and the moisture) and uses it to warm the house.  However, it becomes more of a lint-blowing steam engine than anything, and I am sure you will be shocked to hear that it is not very popular with my very patient wife (who gets to put up with a lot of my sustainability-related projects).

However, there is a relatively new technology called a condensing dryer (sometimes called a ventless dryer) which has become common in Europe and is becoming more available here in the States.  It is based on a traditional heat pump, and does not require an external vent – the warmed air is kept in the house, and the water is collected in a tank. 

I’ll admit I was a little apprehensive about buying this dryer, because it is not cheap, and it is kind of small – about 2/3 the external size of a regular dryer (although the capacity is the same).  However, it is more efficient than a conventional dryer, using about half the electricity to do the same amount of drying.  Plus, you get to keep the heat in the house.  My wife has sent my heat capturing contraption to the recycle bin. 

As usual with my appliance purchases, I bought mine at The Home Depot, and as usual it was a positive experience.  You pick a delivery date on the calendar when you know you can be around, and they come in with the new equipment, and take the old one away (if you like).  Here’s a picture:

So what’s the verdict?  Everyone in the family loves this thing!  It puts out a mild steady heat at floor level while it’s working, so even the dog, who has figured out it is good to lie in front of, is a fan.  It does take about twice as long as a conventional dryer to complete a cycle, but it’s also much gentler on the clothes.  About every other load of clothes you empty the water receiving tub (or you can even pipe it to your washer drain so you never have to empty it).  And at least temporarily, I’m back in the good graces of my wife!! 

Anyone else using a ventless dryer, or any other new appliance ideas we can try?

Dallas’ new luxury rental project, Belmont Village Turtle Creek, is a 195,711 square feet French-provincial style mid-rise offering 201 private apartments and a full continuum of lifestyle and support. The seven-story building called for more than 37,000 square feet of Petersen Aluminum steel panels. BRI Roofing & Sheet Metal of Haslet, known throughout North Texas for their effective management and safety procedures, was the installer.

The new luxury rental project incorporates 23,000 square feet of Petersen Aluminum’s Snap Clad Standing Seam panels in charcoal grey with striations; 14,000 square feet of flush panels in 24ga steel charcoal grey. The project also utilized a total of 30,600 square feet of flat sheet in charcoal grey and sandstone.

Although the project’s architectural standing-seam roof system was designed with steep slopes and relatively short panel lengths, BRI Roofing’s installation went smoothly thanks to their strong focus on day-to-day safety in the operation of each job.

General contractor for the project was Rogers-O’Brien Construction of Dallas.  All the panels and flat sheet for this project were supplied by Petersen Aluminum’s Tyler, TX plant.

Ramona Casino Chooses a Sure Thing

Cherokee Nation Entertainment didn’t want to gamble when it came to building their new historically significant 10,000-square-foot Ramona Casino. This architecturally unique project was completed by Abbco Roofing of Broken Arrow, Oklahoma.  The new casino incorporates 20,000 square feet of Petersen Aluminum’s 24 gauge Flush Panels in copper penny, slate gray and several shades of red. 11,000 square feet of slate grey Horizontal Wall Panels were also used.

Located in Ramona, OK west of U.S. Highway 75, the casino was built on a 20-acre site near an existing casino. Selser Schaefer Architects began the project by developing a phased master plan that enabled consistent casino operations in a temporary facility while the permanent facility was completed.  Also, because Ramona is where the first commercial oil well was drilled in what would become Oklahoma, Casino Ramona’s design is reminiscent of the time period from 1887 to 1906. Two oil derricks at the casino’s main entrance signify the beginning of the petroleum industry.

General contractor for the project was RM Builders of Muskogee, OK.  Petersen Aluminum metal panels for the project were manufactured in PAC’s Tyler, TX plant.
