The recently renovated Koll Airport Professional Center in Irvine, CA received a LEED Silver Certificate in 2009 from the U.S. Green Building Council for Core and Shell. In fact, the building is considered one of the nation’s very first LEED-certified office condominiums. The remarkable transformation of a run-down, two-story, 63,225 square-foot office and warehouse into an eye-catching, single story, energy-efficient, 40,000 square foot office building is the subject of much admiration in Southern California. After removing the second story from the original building, the architects split the lower level into two almost completely separated buildings, added more windows for better daylighting and created two new inviting entryways that provide access to a wide variety of office spaces.
AvL Technologies Corporate Office and Manufacturing Center
The Vision
A single-story strip mall built on an 8-acre site in 1985 in Asheville, NC, had deteriorated to the point where a developer was ready to tear it down and rebuild. Instead the 60,000 square-foot structure–-anchored by a supermarket — was transformed in 2012 into a very attractive corporate office and manufacturing center for AvL Technologies. AvL manufactures mobile satellite communications antennae systems and positioners. Its new corporate office and manufacturing center is now part of an urban village development including contemporary shops, restaurants and residential condominiums. Small shops in the existing building became light-filled offices, and the large grocery and drug store spaces are now dedicated to manufacturing functions. The brick facade, walls, slabs, steel and bar joist structure are all original construction.
The Airolite Look…
The building appears new and designed specifically for its current use, but in reality very little is new. Several design elements featuring custom-engineered Airolite products helped create the new corporate identity desired. Vertical louvers or a brise soleil and perforated aluminum sun controls provide a contemporary and striking visual first impression—adding texture, scaling and detail to the building. A new main public entrance is identified by a sculpture and structural elements that also provide a compositional balance to the louvered façade.
The vertical brise soleil was produced with 12- inch deep extruded aluminum airfoil blades and is supported by adjacent vertical columns. This prominent structure poses bold sight and shadow lines making a dramatic statement with the new façade that reflects the state-of-the-art satellite communications technologies produced within the facility. As a complement to the monumental vertical brise soleil, a horizontal band of sun controls incorporating 0.125″ thick aluminum sheet with ½” diameter round holes spaced 11/16″ on center in a staggered pattern are canted from tube steel supports to provide contrast, texture, scaling and further detail.
That Works
The monumental vertical brise soleil shades and protects the entry to the manufacturing space. The perforated sun controls also yield thermal shading and manage glare imposed on the west-facing windows to advance the energy efficiency goals for the renovation. Tube steel structures frame each window opening and provide support for wind and snow-load forces that cannot be accommodated by the original wall construction. The louvers and sun controls were customized to accommodate the architect’s unique design intent.

It poses a stunning architectural statement while serving as a gateway to the city’s historic Art Deco district. The 300,000 square foot facility includes 38,550 square feet of office space and connects to the city hall administration building via a pedestrian bridge. The garage also provides event parking for the nearby Miami Beach Convention Center and Lincoln Road Mall commercial center.
CHANDLER-GILBERT COMMUNITY COLLEGE WILLIAMS CAMPUS
The Vision
Chandler-Gilbert Community College, Mesa, Arizona, serves more than 16,000 students at three different locations in the Southeast Valley of the Phoenix metropolitan area. The 753-acre Williams Campus was originally created from a portion of the former Williams Air Force Base and is in close proximity to Phoenix-Mesa Gateway Airport. In December, 2008, the college completed construction of Engel Hall, a spectacular new 20,778 square-foot nursing classroom and faculty office building and 6,000 square-foot covered outdoor plaza on the Williams Campus. The first floor of the facility houses student classrooms, laboratory spaces and lounge areas; the second floor houses faculty offices.
Engel Hall was developed as part of the Williams Education Research and Training Master Plan and with an administration directive to provide the college with a new standard of design and architectural materials for future expansion projects across the campus. Achieving maximum energy efficiency and indoor air comfort by minimizing the impact of the hot Arizona sun and a minimum LEED Gold Certification were key requirements of this project. Materials and products employed in the facility were selected based on their insulative value, their durability under extreme regional weather conditions, their visual and textural intrigue, their recycled content and their regional availability.
The Airolite Look…
Architects positioned Engel Hall’s building footprint and created exterior facades to establish a revitalized street presence to the adjacent avenue. The building’s low-profile and sleek lines are visually integrated with the expansive horizon that surrounds the campus. Engel Hall’s engaging but understated exterior immediately projects a progressive, contemporary image for the college and helps support the Master Plan’s recommendation to create new space that “represents the place of this institution in its community.”
A sweeping veil of Airolite sun controls spans the entire length and height of Engel Hall’s second floor providing a very distinctive, visual intrigue to the building during daylight hours and a stunning presence when backlit from the interior at night. The stylish second floor wall of Airolite sun controls also provides a dramatic framed view of the Superstition Mountains for visitors standing in the outdoor plaza where graduation ceremonies, concerts, trade fairs and other campus events will be held. The sun controls’ Kynar 500® Pearlescent Warm Silver finish matches the adjacent storefront and ceiling systems.
That Works
Vital shading provided by the sun controls contribute to energy-efficient cooling and desired thermal comfort for faculty offices without obstructing interior views of the surrounding campus.
Six-inch Airolite airfoil blades form the continuous length and height of the second floor. Blades are arrayed horizontally at 6 inches on center with a solar orientation of 30 degrees and were delivered to the site in approximately 10 feet wide x 6 feet high factory-assembled sections. Each sun control section is secured to steel trusses which also support the overhanging second floor. In addition, the flexibility of the Airolite sun controls relative to solar orientation helped with the user’s thermal comfort, and their recycled material content helped in achieving LEED Gold Certification. Airolite’s sun controls provided shade for the faculty offices, which in turn created a more pleasing visual environment and a more comfortable thermal environment for the users. The sun controls helped contribute to reduced solar heat gain which resulted in reduced cooling and energy consumption. “Airolite’s architectural louvers provided a design element that subtly and successfully addressed the functional needs of the users, energy efficiency requirements of the building, and our own aesthetic goals as a design firm,” stated Paul Goldammer, project manager for Gabor Lorant Architects, Inc.
DONALD M. PAYNE, SR., SCHOOL OF TECHNOLOGY
The Vision
The construction of the Donald M. Payne, Sr. School of Technology brought a new level in career technical education to Newark, New Jersey. Named for the late educator and congressman, the school offers students classes that serve as steppingstones to programs offered by local colleges and universities.
More than 1,100 students attend the school. Its three-story footprint is 320,000 square feet and holds 58 traditional classrooms and 30 larger spaces for specialized programs including the building trades. Students can choose from a wide variety of technical programs that include music production, cyber security, culinary arts, forensic sciences, green energy, and cosmetology.
The facility’s size required several rooftop air handling units to meet the ventilation needs. Wanting to maintain
a clean look for the rooftop, specifications called for using louver screens to hide the equipment from view. The contractor selected Airolite’s inverted blade louver screen, model ENCB609 to hide the equipment from view and offer an attractive appearance for people looking at the facility.
The Airolite Look…
The specifications called for using more than 1,500 linear feet of louver screens to hide the rooftop equipment in more than seven locations on the roof. Airolite’s model ENCB6096 with its horizontal and inverted blades and six-inch depth offered an ideal aesthetic look while ensuring people saw none of the equipment on the roof. Many sections of the louvers had varying height dimensions. The neighborhood around the school also posed a challenge to the setup and installation of the louvers. Fully-assembled louvers in shipment crates were too large to navigate the narrow streets and surrounding property. Contractors asked if the louvers could be delivered in a knocked down (unassembled) form on three separate shipments.
The staggered delivery schedule required coordination between Airolite and the contractors to ensure the louver screens were available when needed. Airolite coordinated the special crating, sequencing and labeling for a smooth and easy install. Since the screens were unassembled, the blades needed to be snapped in place on the louver “tree,” long brackets on which the blades are attached. This assembly required precise placement to maintain the continuous straight lines created by the louver blades. The contractor used a laser to ensure the lines of the louver blades were straight.
That Works
Airolite louver screen ENCB6096 is a versatile, horizontal and inverted blade louver screen that functions extremely well as a sight and security barrier. Its inverted blades help deflect sound upward and away from the surrounding neighborhood, keeping rooftop equipment noise to a minimum.
The completion of the Donald M. Payne, Sr. School of Technology was on time and under budget. Several factors contributed. Many cited Airolite’s ability to work with contractors and deliver the louver screen in the knockdown form. The well-marked, knockdown crating allowed for on-time delivery and easy assembly without overwhelming the assembly area because of narrow streets and limited space. Others mentioned the long spans of the screen. They remarked how it not only hid rooftop equipment but added to the sleek design of the building.

Today, Guildford Town Centre offers over 1,200,000 square feet of leasable area with over 250 stores and restaurants. Airolite architectural louvers are featured prominently on top of the rotunda over the new entrance to the mall.
UNIVERSITY OF COLORADO HOSPITAL
The Vision
On February 2, 2004, the University of Colorado Hospital opened the beautiful new Anschutz Cancer Pavilion on the new Fitzsimons Campus located in Aurora, Colorado. Physicians, employees and patients participated in the design of the state-of- the-art $148.8 million hospital, helping the architects achieve a functional, efficient building with spectacular views of the nearby Rocky Mountains. An important sustainability goal was to maximize the use of natural daylight, while using energy efficient controls to turn-off light fixtures in corridors and exterior areas during bright daylight hours. The reliance on natural daylight resulted in the design team’s need to control glare and heat transmitted through glazing and window systems.
The Airolite Look…
A massive curvilinear window system frames the western view of the mountains from the ambulatory care center. This ten-foot high wall of glass paints a constantly evolving image of the changing seasons evidenced in the roof garden and the majestic Rocky Mountain backdrop. At the same time, this large expanse of glass poses monumental challenges for maintaining energy efficiency. The height of the glass wall dictated a monumental horizontal sun control projection of more than eight and one-half feet to shade the windows to inhibit thermal heat transmittance and glare during peak daylight hours.
A complimentary sun control design with a comparatively modest maximum 4′-0″ projection is utilized over windows in patient rooms located in the south-facing wall to support operation of the patient-operated environmental controls. A special fascia element maintains continuity of the horizontal linear configuration across the red masonry façade.
That Works
Notwithstanding the use of extruded aluminum elements to reduce the weight of the eight and one-half foot sun control assemblies, the extended projection resulted in significant moment forces transferred to the structure by the sun controls. This problem was addressed by departing from the window supplier’s standard frame, which was not designed to accommodate the substantial moment forces transferred by the sun control outrigger. Instead, a horizontal steel member was incorporated in the exterior wall design to address the loads transferred by the sun controls. The sun control outriggers are secured to the steel member with brackets which project through painted aluminum cladding. In addition, the maximum wind design forces required the use of diagonal stainless steel support rods to mitigate the moment forces transferred to the steel member located in the exterior wall design.
The designer elected to utilize vertical extruded aluminum tubes spaced six-inches on center to achieve crisp, uniform, and sharply defined sight lines for the sun control infill. The close center spacing of the vertical tube blades yield a sun cut-off angle that prevents sunlight from passing between the blades except at its maximum height. The hollow shape dissipates heat easily and is a rigid member that can accommodate the 5′-0″ maximum span without difficulty. To alleviate the costly and cumbersome task of fabricating each tube blade to the constantly changing radius, the factory-assembled sun control sections were designed to be segmented about the curvilinear window configuration.
Surprisingly, only the fascia element is radiused to lend the perception that the entire sun control system is comprised of a series of non-linear segments. Lastly, selection of a white fluoropolymer coating enhances the sun control’s capacity to deflect sunlight, head and glare from the windows below and through windows located above the sun control to enable diffused daylight to be projected across interior spaces.
