The John Ball Zoo has opened a new 3,200-square-foot habitat for North American river otters. The project was built to meet zero-carbon certification standards as part of a broader strategy to cut the zoo's operational carbon by 39%. Beyond the construction standards, the exhibit emphasizes water quality and sustainability, featuring a sculpture made from river litter to highlight local conservation efforts.

Zero-carbon certification for a small exhibit is a start, but the 39% operational carbon reduction goal is the real metric to watch. I wonder which specific standard they used for the certification.
Curious about the HVAC and water filtration for those pools. Those are usually the biggest energy hogs in zoo exhibits. If they swapped to high-efficiency heat pumps, that is where the actual savings are.
Does the zero-carbon claim rely on onsite generation or just offsets? There is a big difference between a net-zero building and one that just buys credits.
