Ryan delivers full-service real estate solution to electrical provider
While working closely with DAVIS/Swaim Associates, Ltd., Ryan is leading the development, design and construction of this 250,000-square-foot corporate headquarters building for UniSource Energy Corporation in downtown Tucson, Arizona. Ryan was selected for its ability to provide quality and reliability at a fair price.

The nine-story building will provide improved working space for more than 425 employees of Tucson Electric Power (TEP), the company’s principal subsidiary. It also will include nearly 11,000 square feet of round-floor retail space as well as a conference center, meeting rooms and 500 parking spaces.

Sustainable design to promote energy savings The building has been designed to conserve energy. Its rectangular footprint will minimize exposure to direct sunlight from the east and west, and an integrated shade structure will shield its western face. The exterior will be clad with high-efficiency glass, while the interior will feature energysaving lights, HVAC units and other mechanical systems. A rainwater harvesting system will help ensure all landscaping needs are met with recycled water, while a photovoltaic array will help power the building, including electric vehicle charging stations for employees and visitors. Ryan will seek LEED-NC gold level certification.

UniSource Energy is the largest publicly traded company based in Tucson. The company provides electric service and natural gas to more than 635,000 Arizona customers through subsidiaries Tucson Electric Power (TEP) and UniSource Energy Services (UES).
