The new UniSource Energy Corporation (NYSE: UNS) building allows employees to collaborate in an energy-efficient, modern downtown complex.
UniSource Energy's new corporate headquarters at 88 E. Broadway became fully occupied in November 2011.
The nine story building provides 170,000 square feet of office space for more than 500 people working for Tucson Electric Power, UniSource Energy's principal subsidiary. It includes 11,000 square feet of ground-floor retail space, a state-of-the-art conference center, on-site parking and a long list of environmentally responsible features.
The HVAC system exceeds the baseline threshold for Leadership in Energy and Environmental Design (LEED) certification by more than 25 percent, operating at a level comparable to a 20-SEER residential system.
The building layout and interior office design maximize the use of natural daylight, which streams into every floor through low-e, high-performance glass windows.
The building incorporates a solar water heating system and a 100-kilowatt solar photovoltaic (PV) array featuring the same low-profile, high-efficiency panels installed through the TEP Bright Roofs program. The program offers owners of large buildings an opportunity to lease unused roof space to TEP for the installation of grid-tied solar arrays.
An innovative system directs rainwater through a series of filters and into a 150,000-gallon cistern embedded beneath the building’s main entrance, where it will be tapped to provide irrigation for on-site landscaping.
Dual-flush toilets, low-flush urinals, sensor-equipped faucets and other features designed to reduce water usage by 33 percent.
The building’s demolition and construction process resulted in the recycling of nearly 80 percent of waste materials. The vast majority of concrete, metal and paper-based waste were routed to separate bins and reprocessed for use in future projects.
The integrated garage offers electric vehicle chargers and preferred parking for low-emitting and fuel-efficient vehicles. The garage will reduce the need for employees to use their vehicles’ air conditioners upon leaving the building, saving fuel and reducing emissions.
Low-emitting paint, carpeting, tiles and other finish materials were used for better interior air quality. UniSource Energy also has committed to a “green” cleaning program that will employ only environmentally friendly products.
UniSource Energy’s corporate headquarters exemplifies the company’s commitment to leadership in energy efficiency and renewable energy.
