The first PAC Solar Series project has been installed at the University of Iowa in June, 2010 by T & K Roofing, Ely, Iowa. Consisting of the Petersen Aluminum 24 GA Snap Clad Panel in 24 GA Black Galvalume, PAC installed 280 of the thin film photovoltaic laminates onto 94 Snap-Clad Panels at the factory to provide a total of 38 kW system for the Cambus Maintenance facility at the university in Iowa City, IA. Thin-film BIPV provides a unique synergy with PAC Standing Seam Roofing, combining superior panel performance with increased sustainability and energy generation. The project was funded under Iowa’s Public Transit Infrastructure Program and grants by the Federal Transit Administration. Project architect was Neumann Monson Architects, Iowa City, IA.

Approximately 11,500 sq. ft. of Petersen Snap-Clad metal roofing panels were used on the clubhouse.  An additional 3,500 sq. ft. of Snap-Clad panels were used on the tennis pavilion and postal facility.  The .032 aluminum panels were finished in Silver.

Natelli had used PAC-CLAD on a previous development, according to Dave Dombert, vice president of Natelli and general manager of Main Street Commercial, a Natelli company and the general contractor on the project.  “We knew we wanted Petersen for all of the community buildings at Bay Forest.  We like the aesthetics and the longevity.”

But metal almost didn’t make the cut when the market crashed.  “We considered using less expensive, typical asphalt shingles instead but that would not have done justice to the building,” Dombert said.  “The architect really fought to keep the metal.”

Design for the 12,000 sq. ft. facility was provided by Kishimoto, Gordon, Dalaya PC, Rosslyn, VA.  “The clubhouse is the focal element of the community,” said architect Henry Mahns, project manager.  “As such, the developer wanted this to be the signature building that would set the tone for the entire development.”

“We like the standing seam metal roof for projects that have a harsh environment like this one that’s in a coastal area,” according to Mahns.  “The strength, durability and longevity is just something we rely on with this type of project.  We want it to be there for a long time.”

The roof is accented with deep overhangs, cupolas, dormers and a featured tower element clad with engineered stone.  “We try to use traditional forms with contemporary detailing and we really believe the metal roof enhances the overall look and feel,” reports Mahns.  “The metal has a very clean, tech look to it that we find really works with a lot of jobs.”

Long-recognized as an industry leader in metal standing seam roofing products, Petersen also offers exposed fastener panels, flush panels, composite wall panels and column covers.  All provide the well-known Petersen quality and are available in PAC-CLAD® Kynar 500® finish in 37 standard colors on steel and aluminum.  Most colors meet LEED®, ENERGY STAR® and cool roof certification requirements.

The SNAP-CLAD system has been designed for architectural aesthetics and structural performance and meets Florida’s Building Code and Miami-Dade NOA standards for wind-uplift resistance. The 16” wide, 24 gauge galvanized steel panels were finished in Copper Penny.  Approximately 4,000 sq. ft. of PAC-CLAD flat stock was used for flashings and gutters on the project.

Installation of the Petersen panels was done by RAE CO of Ocala, Ocala, FL. Produced in factory formed lengths up to 55 feet, Petersen’s PAC-CLAD Panels are Herr-Voss corrective leveled to provide superior flatness.  Longer lengths are available by consulting the factory.  PAC-CLAD® Kynar 500® finish is now available in 37 colors on steel and on aluminum.  Most colors meet LEED®, ENERGY STAR® and cool roof certification requirements.

As renewable energy technology continues to develop and net-zero energy buildings become more feasible, it’s no longer impossible to envision a future where buildings of all kinds can power themselves and stand on their own. For example, we’re seeing more examples of buildings incorporating rooftop solar photovoltaic arrays to offset their own power use. It’s exciting technology and, as efficiency increases and costs come down, it certainly will become more commonplace. I like to even hope that integrated power generation eventually will become just part of what’s expected of a building.

PV technology still is in its relative infancy and has a long way to go before it truly becomes cost effective enough for wide-spread use. For projects installing such technology today, two factors are of great importance: government incentives and the longevity of the system. Government incentives and tax credits can help with the up-front expense, and longevity allows the system’s costs to be spread out over a period of many years. The longer the operational life, the greater the return on investment.

Because most current solar PV arrays have an operational life expectancy of more than 20 years, it’s important to think about the longevity of the roof system the PV panels or laminate sheets are installed on. When you factor this into the equation, standing seam metal roofs become not only an ideal solution–in many cases they may be the only truly viable solution.

It reminds me a bit of the early days of those TV/VCR combo units. I remember reading several reports that warned consumers about the technology because oftentimes the VCR part of the appliance would break down years before the TV part would, so you’d be left with a half-functioning device. In much the same way, it doesn’t make much sense to install a long-lasting solar power-generation system on a roof that’s going to need to be replaced halfway through the life of the array.

A cornerstone of the sustainability movement is a shift to a more long-term view of things. How will decisions we make today play out five, 10 and 20 years from now? With its durability and low maintenance requirements, metal roofing fits very well into this kind of philosophy. As we come to expect more from our buildings and make them more long-lasting and independent, metal has a big role to play.

Approximately 100,000 sq. ft. of PAC-CLAD Snap-Clad Panels were used in the major tear-off and re-roof project.  The 24 gauge, 18” panels were finished in Forest Green.

Project design for the 189,000 building was provided by MAHG Architecture, Inc., Fort Smith, AR.  According to partner Galen Hunter, “The school saw this as an opportunity to resolve the leakage problem and bring the building into conformance with the master plan.  The re-roof was done in sections while classes were in session and the whole process went smoothly.  We’ve spent a lot of time researching roofs and we’re very confident with the Petersen system.”

Installation of the roof was done by Harness Roofing, Inc., Springdale, AR.  “The school originally wanted a metal roof when the building was constructed 15 years ago but opted for a less expensive shingle roof that failed,” said James Russell, project manager.  “The building had been well maintained and adding the metal roof made it look like new.  The only challenge was working around the students.  We had to keep moving safety fences and equipment.  And, of course, we had to remain covered-up and water tight at all times.  But the building really got a modern facelift and looks great.”

Over the past 25 years, I’ve been pleased to see the increasing amount of metal construction products—metal building systems, cold-formed steel stud framing, metal roofing and metal wall panels—that are being used in health care construction sectors, both for new projects and retrofit/renovation. This includes everything from single-practice offices to well-known, multi-story hospitals. In my opinion, there’s a vast potential for metal products in this growing market segment.

Let’s face it, as members of the Baby Boomer generation continue to march into their retirement years, there are going to be more ailments that require medical treatment. At the same time, due to an increased emphasis on preventative care, we’re likely to see growing numbers of younger people making regular visits to health care professionals. One thing for certain is that the need for health care facilities has seen remarkable growth over the past decade or two, and there is no apparent end in sight to the need for additional facilities.

With a tremendous amount of benefits to offer—from low life-cycle costs to environmental benefits to aesthetics—metal construction products appear poised to play key roles in future health care projects.

Yes, the economy isn’t what we’d all like it to be, but it’s up to you to make sure you take care of what you can control. There are opportunities out there that are working in your favor right now!  You’ve all heard about the stimulus package and the tax rebates available for consumers installing energy efficient products — everything from metal roofing to windows, insulation and water heaters.

That tax rebate has to be a tool that metal roofing installers use to sell more metal roofing.

I talked to a Florida metal roofing installer in late June who installs exposed fastener panels on residential re-roofing projects — he is matching the price of asphalt shingle installations. And he’s able to do this because the price of asphalt shingles is climbing due to its petroleum base. He said it is more cost efficient for his company to install metal panels over a single layer of asphalt shingles than it is to tear off asphalt and put down another asphalt roof.

It’s possible the price of metal is closer to asphalt roofing than it’s ever been. What are you going to do about it?

Petersen Aluminum has introduced the PAC Solar Series, which integrates cutting-edge photovoltaic technology with the durability of a standing seam roof system.

Thin-film solar laminate is fused to the surface of the metal panel substrate to create a green solution for energy generation.

Unlike polycrystalline photocells that are heavy and fragile, no roof penetration or structural support is required with the flexible and durable PAC Solar Series.  The Solar Series includes a complete, standardized system with schematics and specifications for all electrical components.

Provided through the EnergyPeak™ Program, PAC Solar Series is available on these Petersen profiles:  Snap-Clad, Redi-Roof, Tite-Loc, Tite-Loc HS and Tite-Loc Plus.  Solar Series roofs provide payback in 10 years or less and offer a 20-year warranty.

Located at a historic trolley station site overlooking Chesapeake Bay, the new Mary Pretlow Anchor Branch Library in Virginia Beach, VA provides an iconic look for visitors and residents arriving at the bayfront.

The roof of the structure features a wide array of slopes, levels and intricate details that create an impressive visual display.  A cupola tops off the building to add to the coastal feel.

Approximately 30,000 sq. ft. of PAC-CLAD .040” aluminum Silver Metallic Snap-Clad panels provided the flexibility to meet demanding design objectives.  In addition to stunning aesthetics, the panels are rated to meet local windload requirements.  The Kynar 500 finish over the aluminum substrate also provides superior resistance to the elements in the coastal environment.

Design for the project was provided by The Design Collaborative, Virginia Beach.  “We had decided from the outset that the roof would be standing seam aluminum because of the salt air,” according to Ed Lazaron, principal and project architect.  “The building is on a spectacular site overlooking the shipping channel into the Bay.  The City Council wanted a ‘beach style’ look with a large, sheltering roof that would be compatible with the older houses along the beachfront.”

The design also called for an internal gutter system.  “It was a challenge because the overhangs were so large,” Lazaron said.  “We created a complex internal piping system that could be hidden in the roof structure.  The roof really provides the signature look that we wanted and the reaction from the community has been outstanding.”

Installation of the PAC-CLAD roof was done by Westar Roofing Corp., Virginia Beach.  The general contractor was Sun Bay Contracting Inc., Virginia Beach.

Long-recognized as an industry leader in metal standing seam roofing products, Petersen also offers exposed fastener panels, flush panels, composite wall panels and column covers.  All provide the well-known Petersen quality and are available in 37 standard colors on steel and 36 standard colors on aluminum.
