Overview of Project

The Oklahoma State Capitol building underwent the first entire building renovation since its construction in 1917. The eight-year, $245 million endeavor modernized the building with ADA access, security systems, fire alarms, sprinkler systems, lighting controls, and building automation climate controls to help preserve the Capitol's collection of artwork while also providing comfort to the occupants.


As a subcontractor of Manhattan Construction, ES2 installed new building automation controls throughout the building. All the major equipment was replaced including the water source heat pumps that serve the offices and common areas, and supporting equipment such as DOAS, RTUs, AHUs, EFs, and an ice melt system. Integration on the project included Lutron Lighting, DriSteem Humidifiers, AAON DOAS, Prestige Solo Boilers, and a Carrier chiller. The ability to monitor the equipment via integration was critical to allow specific energy-saving strategies such as relaxing space setpoints when the Lutron system reports a vacant space.

ES2’s BAS team incorporated all this equipment into WebCTRL to streamline building management by utilizing scheduling, trending, alarming, equipment graphics, and thermodynamic floorplans, all created by ES2's Engineering team. The extensive timeframe of the project spanned two version updates of WebCTRL, uniquely requiring an upgrade during the project to bring the original system, WebCTRL 6.5, up to WebCTRL 8.0. ES2’s TAB team performed air and water balancing on over 500 water source heat pumps and all associated equipment.
