Sun Devil Fitness Complex Expansion

LEED Gold goal, LEED Platinum outcome.

ASU wanted the expansion of its Tempe campus student recreation facility to be as efficient as possible in operation. AEI devised an assortment of resourceful energy-saving and sustainable design features for this large-scale, extended-hours, multi-purpose facility, initially targeting LEED Gold certification and ultimately achieving LEED Platinum.

LEED Status

LEED Platinum

Building Size

110,907 sq. ft.

Engineering scope also included participation in the LEED process, and building information modeling for a 1st floor 2-court gym, a 2nd floor 3-court gym, strength and cardio equipment rooms, a weight-training facility, wellness center, reception area and

AEI participated in early site selection studies and systems analysis, finding construction cost saving by determining that existing electrical service could support the addition, and adding mechanical service adaptable for anticipated future expansion. Solar thermal collectors serve the absorption chiller (vaporizing refrigerant), the large swimming pool is used as a heat sink, and a 280 kilowatt photovoltaic array is on the roof.


The project was designed to be a campus showpiece facility with high-end interior treatments, helping to meet overall campus athletic demands.

EUI reduction

An addition to other sustainable features, all surface water runoff for the building is contained on site through underground storage tanks and large retention basins in the surrounding desert landscape. AEI also provided commissioning services, ensuring that systems were effectively brought on-line and that the building meets its energy targets.
