BNIM designed this energy efficient office building to house the Iowa Utilities Board (IUB) and the Office of the Consumer Advocate (OCA). An infill development on the State of Iowa Capitol Complex in downtown Des Moines, the project was developed on a challenging, awkwardly proportioned landfill site and serves to create a gateway to the complex at its southeast corner. The building serves as a testament to the sustainable stewardship of the State of Iowa. It is a model office building demonstrating proven, cost-effective energy efficiency measures for new construction.

The building is organized into two wings: the north wing comprises the IUB, while the south wing is comprised of the OCA on level two and common space on level one. The common space includes a hearing room, conference center and lounge space. Linking the two wings is a two-story lobby housing vertical circulation and service functions. An entrance courtyard sits between the wings and a plaza space is located off of the south wing.

The project was designed to integrate replicable sustainable strategies; serving as a demonstration project for other government facilities at the state and local level, and also for the general public and private enterprise. While many of the employed strategies are "off the shelf" to various degrees or have been used elsewhere, what makes this application particularly significant is the multitude of strategies integrated together to truly achieve a building of exemplary energy performance.

The facility is consuming 75 percent less energy than a code compliant building.
