Resilient infrastructure.
Delivered as a service.

Siena Infrastructure develops, finances, owns, and operates resilient thermal infrastructure for mission-critical institutions — hospitals and health systems, airports and aviation, universities and research institutions, and government and public campuses. Instead of funding a chiller-plant replacement themselves, these institutions contract with Siena for the outcome: capacity, availability, resilience, and thermal service under a long-term agreement, with zero upfront capital.

One counterparty. Long-term accountability.
