Design Achievement - A 1918 government building on the Historic Registry became a sustainable design exemplar through a partnership between the GSA, DLR Group|Westlake Reed Leskosky, and Beck Construction. A comprehensive renovation of the Wayne Aspinall Federal Building focused on restoring and preserving historic character while employing a range of modern systems and updates for occupant comfort and energy use reduction. The four-story building houses numerous professional federal agency office tenants, who now benefit from the return of the original high ceilings, enhanced daylighting, and increased openness made possible by an innovative reconfiguration of non-original fire separation assemblies. Visitors are greeted by a restored lobby with period-based light fixtures and restored original artwork, while technologically advanced security is thoughtfully screened from the entry view. The project has received over a dozen awards, including a National GSA Design Award with citations in architecture, interior design, engineering, and preservation. The project was recognized by the AIA Committee on the Environment as a Top Ten Green Project.
Scope Summary – The $14.2 million scope of this modernization project for a 100-year old, 42,000-SF courthouse included public lobby/security upgrades, alternate ABAAS Ramp at the main entrance, tenant reconfiguration and improvements, blast mitigation study, public restroom upgrades, and replacement of elevators, windows, and the roof. The project was delivered to the GSA three months ahead of schedule, despite a complex phased approach and full occupation during construction. The outcome is LEED-NC Platinum accreditation and the GSA’s first site net zero energy building on the National Register of Historic Places. Current performance measures an energy use intensity (EUI) of just 6 kBTU/SF/year, compared to a median courthouse EUI of over 90. Building physics analysis studied space thermal comfort, natural ventilation and daylighting potential, envelope thermal performance, renewable energy potential, and whole building energy performance. The integrated design achieves a 50 percent energy cost reduction compared to ASHRAE 90.1-2007, cost-effectively exceeding ARRA requirements. A roof-canopy-mounted 123 KW photovoltaic array actively contributes to an even lower target of near-net-zero energy use. DLR Group|WRL provided architectural, MEP engineering, structural engineering, interior design, LEED and High Performance Green Building Consulting, historic preservation, information transport and lighting design services.
DLR Group acquired Westlake Reed Leskosky in September 2016. Today, the combined design expertise and resources of Westlake Reed Leskosky and DLR Group serve clients as a global, integrated design firm committed to elevating the human experience through design.
