New UniSource headquarters

Seven employees of Tucson Electric Power (TEP), the main subsidiary of UniSource Energy, reported to work in the company’s new nine-story, $60 million downtown headquarters for the first time on Thursday, Nov. 3. 


Today (Nov. 7), another 85 employees joined them in the new 232,000-square-foot building at 88 E. Broadway.

The headquarters eventually will house some 400 employees who are currently located in leased space at 1 S. Church Ave. and the utility’s operations center at 3450-4350 E. Irvington Road.  The first seven employees to move in all were members of the utility’s Computer Support Center.    

“By bringing so many employees together in a space designed for our specific needs, UniSource Energy’s new corporate headquarters will help us work more efficiently and effectively on behalf of our customers,” said Paul Bonavia, CEO of UniSource Energy and TEP.


The building will alleviate overcrowding at TEP’s Irvington Road campus where many employees have been working in trailers.  Employees and departments that frequently work together will now be located under the same roof – many on the same floor – greatly reducing vehicle travel between the two locations.   


The building green-build features include:

Efficient heating and cooling:  The building’s HVAC system exceeds the baseline threshold for Leadership in Energy and Environmental Design (LEED) certification by more than 25 percent, comparable to a 20-SEER residential system.


Natural lighting:  The building layout and interior office design maximize the use of natural daylight on every floor through low-e, high-performance glass windows.


Solar power:  The building will incorporate a solar water-heating system and a 50-kilowatt photovoltaic array featuring the same low-profile, high-efficiency panels installed through the TEP Bright Roofs program.   


Water harvesting:  Rainwater will be captured through a series of filters in a 150,000-gallon cistern where it will be used to irrigate on-site landscaping.


Water conservation:  Dual-flush toilets, low-flush urinals, sensor-equipped faucets and other features will reduce water usage by 33 percent.


Vehicle emissions:  The garage offers electric vehicle chargers and preferred parking for low-emitting and fuel-efficient vehicles.    


Recycled construction waste:  The building’s demolition and construction process resulted in the recycling of nearly 80 percent of waste materials for re-use in future projects.


Green build materials:  Low-emitting paint, carpeting, tiles and other finish materials were used for better interior air quality.  UniSource Energy also will employ a “green” cleaning program using only environmentally friendly products.
