The Theodore Roosevelt Presidential Library in Medora, North Dakota, opens on July 4 with a design focused on low-carbon construction and net-zero performance. The 96,000-square-foot building uses rammed earth walls, cross-laminated timber, glulam, and low-carbon concrete to reduce embodied carbon. It targets Living Building Challenge Full certification, LEED Platinum, and SITES Platinum under a Four Zeros framework for energy, carbon, water, and waste. The building includes 216 geothermal wells expected to generate 105% of its annual electricity, a closed-loop water system that captures and treats all rainfall on site, and a 121,000-square-foot rooftop planted with over 140,000 native prairie plants. The project also restored native prairie across the 93-acre site using locally collected seeds. If it achieves its targets, it would be the only carbon-neutral presidential library in the world.

Rammed earth and mass timber at this scale is rare. The embodied carbon savings depend on the concrete mix and CLT sourcing details. Would like to see the actual carbon numbers per square foot.

216 geothermal wells claiming 105% of annual electricity is a big claim. Need to see the load profile and whether that includes heating and cooling or just plug loads. Net zero on paper vs real operations are different things.

The Four Zeros framework is ambitious but the real test is verification. Living Building Challenge requires 12 months of operational data. That will tell us if the closed loop water and geothermal actually deliver. Worth watching the audit results.

The prairie restoration and seed bank component is interesting. That is a tangible carbon sink and biodiversity gain beyond the building itself. Would be good to know the sequestration estimate for the restored native prairie over 20 years.
