State office building achieves LEED Platinum

As the first state office building nationwide to receive the U.S. Green Building Council’s LEED Platinum certification, the Lewis & Clark State Office Building in Jefferson City, Mo., has charted new territory. Careful collaboration between the design and architectural teams, as well as innovative HVAC components from McQuay, help the building save 60% in energy costs compared to a building designed for ASHRAE Standard 90.1-2004.

The facility is one of only 16 buildings in the nation—and the first state office building nationwide—to receive a Platinum certification, the highest rating in the LEED-New Construction (NC) Version 2.1 program administered by the U.S. Green Building Council.

According to Laura Lesniewski, architect and project manager with BNIM Architects in Kansas City, Mo., many synergies resulting from the architectural and engineering decisions contributed to the building’s energy efficiency.west faces [about 70 feet] reduce heat gain from the intense afternoon sun in the summer.  In addition, external sun shades over the south-facing windows help reduce the load on the air conditioning system.  Internal light shelves just below the clerestory windows reflect light up onto the ceilingand, from there, deep into the building’s interior.  We chose low-E glass to let in light, but reflect heat away from the building; daylight sensors throughout the building automatically turn off lights when there is enough natural light.”
