MBH Architects completed the 1450 Chapin Ave. building renovation design in Burlingame, Calif., with seismic upgrades, interior updates and a modern exterior skin. The 12,500-square-foot, industrial-style structure is illuminated by LED lighting and accented with zebra wood paneling, stone, custom glass rails and chandeliers. The original twostory structure was built in 1957 with cement plaster, single-paned aluminum windows and primarily wood framing.

Aluminum composite material (ACM) panels wrap the roofline to the ground at the street elevation; the metal architectural element tie the two-story building together. The roofline, second-floor canopy and entry are clad with ACM panels. Alumtile Inc. supplied 1,194 square feet of its AllBond Alumtile ACM panels with a coil-coated Kynar 500 finish for the entry canopy and an additional 694 square feet at the roof parapet. Six-mm ACM was specified for areas that could potentially be walked for window washing and other reasons; 4-mm ACM was used everywhere else.

Old windows were replaced with larger, double-paned, aluminum, energy-efficient windows. Decorative aluminum louvers were installed to protect windows from sunshine. Rowe Fenestration Inc. supplied 862 square feet of The Airolite Co. LLC's louvers with a Mica Pearlescent Bright Silver AL222 finish. The sun control system has 8-inch fan blades at 20 degrees; blades weigh 2.172-pound per linear foot. Additionally, Arcadia Inc. supplied 2,633 square feet of its 2-inch by 4 1/2-inch AG45IT Series Thermal Broken Storefront Framing and Center Glazed System with a Class 1 Clear Anodized finish.

The exterior skin was constructed with zinc and ACM paneling, an aluminum-andglass wall system and cement plaster. RHEINZINK America Inc. supplied 352 square feet of its 22-gauge, 17-inch by 34-inch, 1/8-inchthick Flat Lock tile zinc cladding system with a pre-weathered Blue Grey finish. Additionally, RHEINZINK zinc panels enclose the lobby staircase. Zinc shingles were modulated to reflect the concrete masonry unit pattern in the original lobby. HVAC and electrical systems were replaced with more effective and energy efficient systems and the R-value of the roof insulation was increased. The $850,000 project was completed in June 2014.
