Natatorium renovations with
sustainability in mind
Sustainability is defined by the United Nations as “meeting the needs of
the present without compromising the ability of future generations to
meet their own needs.” When the IU Natatorium underwent a $20 million
renovation, the building was designed with sustainability in mind.
- All lights in the IU Natatorium were replaced with LED light bulbs.
- LED bulbs have an outstanding operational lifetime expectation of
100,000 hours, which equals 11 years of continuous operation or 22
years at 50 percent operation.
- By eliminating the existing fluorescent and metal halide luminaires
and using LED luminaries, the updated area lighting uses (at
minimum) 43% less energy than prior to renovation.
- Automatic lighting controls (occupancy sensors) and a new lighting
control station for the Natatorium area allows for light dimming, will
further reduce overall energy usage.
Mechanical plumbing and pool items
- The filtration system for the competition and diving pools were
replaced with regenerative media filters. The backwash rate and
duration for the regenerative filters is significantly less than the
previous filtration system, reducing water usage by 65%.
- The pool UV filtration system for the competition and diving pools were
both upgraded to a compact design, reducing overall consumption for
the filtration system by 25%.
- All new air handling units were equipped with VFD drives to afford a
closer electrical usage to match the load in the spaces served.
- Aged, inefficient fan coil units were replaced with new that operate at a
- All traditional water fountains were replaced with water bottle filling
stations that allow users to refill their reusable bottles. The stations also
track the number of water bottles kept out of the landfill from each use.
