Sun Devil Fitness Complex Expansion

Exceeding sustainability goals.

Arizona State University (ASU) wanted the expansion of its Tempe campus student recreation facility to be as operationally efficient as possible.

To accomplish this, AEI implemented an array of high-performance, sustainable design features in the Sun Devil Fitness Complex — a large-scale, extended-hours, multi-purpose facility. While initial project goals targeted LEED Gold certification, the building's energy-saving features surpassed expectations, ultimately achieving LEED Platinum.

Engaging in early site selection studies and systems analysis, AEI determined the facility's existing electrical service could support the expansion, resulting in significant construction cost savings. An added mechanical service was also implemented to ensure adaptability for future expansion needs.

Sustainable design strategies include solar thermal collectors serving the absorption chiller (vaporizing refrigerant), utilizing the large swimming pool as a heat sink, and a 280-kilowatt rooftop photovoltaic array. 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 online and that the building meets its energy targets.
