As part of its mission to protect and restore Missouri’s natural resources, the Missouri Department of Natural Resources commissioned a new 120,000-square-foot office building to consolidate all of their employees under one roof and to showcase affordable, cost-effective and replicable “green” strategies.
The site, selected after an extensive evaluation process, originally housed part of the Jefferson City Correctional Facilities, which was carefully deconstructed prior to construction. One goal of the restorative site plan was to completely eliminate stormwater runoff from the site. To accomplish this, the site was carefully designed with level spreaders, bioswales, native prairie plants and ecosystems. Rainwater from the roof is collected in a 50,000 gallon storage tank, which provides flushing water to the building’s toilets.
The building is organized around a four-story atrium space that opens to a grand view of the Missouri River Valley. Oriented along an east-west axis, the building was developed with a narrow footprint to maximize daylighting strategies. Each elevation responds to its respective climatic condition. Precast concrete sunshades protrude from the south facade and allow low sun angles to provide supplemental heat during the winter months yet block heat gain during the intense summer months. The north facade was developed without shading devices, a design strategy that maximizes daylight and views toward the river. Different glazing was specifically selected for each elevation. Operable windows are distributed throughout the building to allow for natural ventilation.
Maximizing daylight and minimizing energy costs were primary goals of the owner. By locating open office space around the perimeter of the building, occupants are exposed to natural light and views. Exterior sunshades and interior fabric light shelves “harvest” sunlight, directing it into the core of the building. Several strategies maximized the efficiency of the HVAC system: a dedicated outside air system, hybrid ventilation air handlers, natural free cooling through the use of a chilled water thermal storage tank charged by the tower during cool night hours. Daylighting controls combined with a thermal storage system significantly reduce peak power use and sizing. Photovoltaics provide 2.5% of the building’s energy needs, and a solar hot water system is used to help supply domestic hot water.
The building has received a LEED® Platinum rating from the U.S. Green Building Council.
