The $15.5 million energy efficiency renovation was designed and constructed by Ameresco in several phases over the last two years. Key upgrades included replacing 350 guest room fan coil units with new smart thermostats, a new central chiller plant with added redundancy for air conditioning, new hot water return distribution for reduced hot water wait times, and new electrical transformers.

The new equipment will continue to be maintained and operated by Ameresco for the life of the EaaS agreement.
