JOHNSON CONTROLS GLOBAL HEADQUARTERS
The existing campus, built in the late 60’s, reflects man’s modern ability to conquer nature. This is highlighted by the two million gallon reflecting pool and fountain, which suggest that the main building is floating. The new additions, situated around an overlooked tributary of the Milwaukee River, have been designed to be harmonious with nature while maintaining the modernist vocabulary of the existing buildings.
The Johnson Controls’ site plan was conceived to increase useable floor area while reducing site surface coverage and improving, per the Department of Natural Resources, surface runoff to the tributary. This was achieved by removing half of the surface parking and relocating this to a parking structure, situating the new buildings to allow for natural runoff of the site and creating rain gardens, aqua beds and filtering fields to slow and clean the water before it reaches the aquifer.
The 35,000 sf building which connects the existing campus to the new and contains the public functions of the campus literally bridges over the aqua bed so as not to disturb its natural path of water flow or create the need for a culvert. Its roof contains solar panels which contribute to the hot water supply of the building as well as a green roof. The main feature, however, are the three massive light monitors which visually locate the cafeteria and significantly reduce the need for artificial light.
The new 85,000 sf Power Solutions building houses Johnson Controls Lithium Ion Battery division. The building is designed, while taking cues from the existing campus, around the physics and properties of the battery itself. The building is clad in Wisconsin limestone and applied as an open jointed rain screen system to allow an equal pressurization in the cavity reducing the chance for water to penetrate the building. It also utilizes a large light monitor to signify its public space and reduce the need for artificial light. Because of the orientation mandated by the location of the tributary, the ornamentation of the building, a vertical perforated louver which represents the cellular nature of the batteries as well as their main material, copper, is purely functional and simply keeps the eastern and western light from entering the building; therefore reducing cooling loads and glare.
The (2) existing buildings, Amenities Building, and Power Solutions Office building all received LEED Platinum Certification.
