Arizona's economy has historically been based on the Five Cs: cattle, climate, cotton, cactus and copper. Because of this, copper was chosen as a prominent and successful component of the Biomedical Sciences Partnership Building (BSPB) at the University of Arizona's Phoenix Biomedical Campus, Phoenix. For the building, it proved to be a regional, recycled and recyclable product helping to earn it a Judges Award.
BSPB is the second phase of a two-part project. "The first phase included the design of the interdisciplinary Health Sciences Education Building (HSEB), which became an innovative and distinct urban response specific to the Sonoran Desert," says Arnold Swanborn, AIA, LEED AP, associate principal at CO Architects, Los Angeles. "The iconic nature of the folded copper panels invokes the striated geology of the surrounding mountains and was utilized in the second phase for BSPB." Inspired by the deep recesses of desert cliff dwellings, BSPB's sloping, shifting, self-shaded south façade rises 10 floors above the vegetated canyon wash, resembling desert escarpments.
A joint venture between DPR Construction, Phoenix, and Sundt Construction, Tempe, Ariz., managed the construction process. CO Architects shared architecture responsibilities with Ayers Saint Gross, Phoenix.
Approximately 295,000 pounds of cooper constitute the exterior finish. KME America Inc., Oak Brook, Ill., was the copper supplier. The building's striated texture is achieved by manipulating recycled copper, to form an innovative cladding system, which is suitable for the desert climate. To make this sunscreen, the cladding system uses nearly 4,800 formed, bent and perforated copper panels to reflect light and cast shadows that reflect the canyon walls.
Kovach then fabricated into a series of full-size panel mock-ups. The team created the appearance of a naturally occurring random pattern using only 26 panel types, arranged in multiple combinations, using parametric software to generate algorithms for the randomized sequence of panel types. The panel size and depth balanced visual and performance goals with cost-saving strategies, such as keeping the overall panel size to domestically available copper.
One of BSPB's greatest challenges and opportunities was its fast-track delivery. "Prefabrication contributed heavily in conforming to the schedule," Swanborn says. Metal wall panel components were pre-assembled to increase quality, save time, and ensure early building enclosure for timely building systems installation and interior framing. "Sundt integrated the design process, which helped eliminate design re-work and give the team the opportunity to modify decisions along the way, maintaining design intent and budget without wasted work hours," says Kent Bosworth, project executive at DPRSundt.
Copper was selected after extensive research into the qualities of metal alloys, regional appropriateness, and visual character. "Copper's conductive qualities suited the skin and thermal chimney concepts," Swanborn says. "Its conductive qualities to heat and create a temperature difference to promote convection, effectively exhausted heat and minimized its transfer into the building. The natural patinization of copper made it a low-maintenance solution for the client to benefit from reduced cost maintenance."
BSPB's copper-clad exterior serves as a shield, protecting its interior from direct solar exposure. Adapting rainscreen technology, the building's design team took a system typically used in the Northwest and created a way to utilize copper cladding as a sunscreen, mitigating the excessive heat. A fully integrated system of copper panels, a 2-inch air space, rigid insulation and a waterproofing membrane work together to absorb the radiant heat, and allow it to vent out through the building's top. While the copper will likely remain a brownish hue in this arid climate, its color will change and become variegated over time, further connecting it visually to the surrounding mountains. The copper cladding for the building is made up of 90 to 95 percent recycled material, which helped to achieve its LEED Silver certification.

Status: Greg +1 (volunteers)I stumbled across this board and am hoping to get some advice from you. I’m in the process of a kitchen remodel and my tile floors were laid earlier this week. I just assumed he would be coming back to do the grout work, but he said the contractor and his guys would be coming back to do it. I wasn’t happy about this, but having trust in the contractor, I figured it was in good hands.
Well, yesterday the grout went in and it looks nothing like the grout I selected, TEC grout summer wheat 982. It’s almost a pink color. It’s hideous. I ran back to the flooring store and grabbed the sample and it’s nothing like the color I selected. I’m posting pictures.
The contractor thinks he did everything right and is shrugging his shoulders. He knows what he’s doing. He won’t fix it on his dime.
Any advice on what might have gone wrong? There are certain places that the color is right. The floor is not uniform.
Hi Amy, welcome. Sorry to hear about the botched grout. Looks like they used too much water when cleaning. Was this grout regular TEC grout? Have you paid them all you owe them? If not I would hold money back until they correct it.
He may think he knows what he's doing but the pics says otherwise.
Like mentioned there was too much water whether it was in the mix or the wash, maybe both. Minerals in tap water can alter results. Not dry mixing the powder could result in different colors. This is on the contractor, he should be fixing on his dime.
Not only what they said, but the unevenly shaped joints are a clear case of not finding shiny the joints properly.
In the circumstances you describe, I would withhold money from the remaining balance until it’s fixed.
....a clear case of not finding shiny the joints properly.
I'm guessing that "finding shiny" is Wisconsinite
