Somerton City Hall, Somerton, Arizona
LEA Architects led by Lance Enyart, AIA, LEED AP and Larry Enyart, FAIA, LEED Fellow, designed the New Somerton City Hall to accommodate the day-to-day administration of the City’s services and programs and reflect the current and future aspirations of the City. The Architecture drew inspiration from the agricultural context of the land, crops and culture of this surrounding community using exposed regional masonry as a critical component of the design. Natural building materials including extensive use of local ground-face concrete masonry for exterior and interior walls in combination with exposed structural steel, concrete, glass, and standing seam metal wall panels define the building surface and exude a sense of sustainability and presence. The random vertical patterning of screen and patio walls are of of turned open cell 8x8 masonry units which in combination with the varied color and pattern of the buildings metal skin is designed to be reflective of the imagery of the surrounding agricultural row crops inherent to the area. The Somerton City Hall project includes an expansion and new focus on the existing historic Sanguinetti Park to provide an enhanced public amenity for the Citizens of Somerton and a new formal front door for their New City Hall; designed to be sustainable and energy efficient incorporating numerous passive, active, and regionally appropriate sustainable building principles meeting USGBC LEED standards. The ground face concrete masonry block used extensively on the interior of the building and exposed ground concrete floors provide an attractive, durable, and low maintenance surface with inherent thermal mass to help maintain consistent and comfortable indoor temperatures. Enhanced building insulation in the wall and roof assemblies and insulated Low-Emissivity (Low-E) glazing provide resistance to the heat transfer through the building envelope. The building utilizes a highly efficient Variable Refrigerant Flow (VRF) mechanical system and LED lighting to reduce the building's energy consumption. Indigenous desert landscaping, low flow plumbing fixtures and dual flush toilets are utilized to reduce the Building's water consumption. Low emitting materials and finishes were used in the Building to reduce indoor exposure to formaldehyde and other Volatile Organic Materials (VOC). Access to Natural daylighting and views to the exterior are provided throughout all of the building's occupied spaces. Solatube vertical daylighting devices are also used to bring natural light into the interior of the open office environments. Deep building overhangs cantilever and protect the south and north side curtain wall glazing which frames the full height masonry defining the buildings main entry. Perforated metal vertical shade structures are strategically located on the buildings east and west elevations to protect the glazing from the sun and reduce solar heat gain into the building. The New Somerton City Hall includes classroom Space for Arizona Western College bringing higher education opportunities to the Citizens of Somerton.
