First LEED-NC Building in Central Ohio Provides Design for Collaborative Work Culture

When envisioning a new headquarters for its expanding company, IGS Energy placed high value on minimizing its environmental footprint and maintaining a close-knit employee culture despite recent growth. As the company’s architectural partner, OHM Advisors designed a 104,500 sf visually transparent space that maximizes daylight and encourages staff interaction. The first building in central Ohio and the largest building in Ohio to achieve LEED-NC Platinum certification, it includes open offices, conference rooms, a consumer call center, training rooms, a cafeteria, data center, print center and locker rooms as well as an underground parking facility for 65 vehicles.

The building has an extremely efficient building envelope, a geothermal HVAC system, an efficient lighting system, light shelves and roof monitors and is 46% more energy efficient than average. Additionally, 96 kva of solar energy is generated on the roof annually. In the planning and design of the whole corporate campus, special consideration was given to stormwater retention as well as the preservation of natural vegetation, open space, and tree stands.

The 17-acre site originally included expansive setbacks from Interstate 270, but our team rezoned the property for maximum building visibility. The team also worked with the city of Dublin to create the Rezoning Submission Package to allow for the development of future buildings on the campus, which enabled a site and facility master plan providing for the completion of a second, 75,000 sf building which can be connected to the larger building by an atrium/causeway. The development text is written for two parcels so that each building can function independently.
