About the Client

The owner of 1313 North Market partnered with Seiberlich Trane Energy Services to complete $2.4MM in energy savings improvements that increased energy efficiency and occupant comfort. Upgrades were made to the 500,000 square foot multi-tenant office tower to improve aging infrastructure, enhance controls for tenant spaces, and meet the company’s energy and environmental goals.

Seiberlich Trane Energy Services completed an investment grade audit of the facilities and executed a performance contract to provide design and construction of the needed building improvements. The project leveraged a lot of existing infrastructure to keep costs low and was executed with minimal disruption to tenants.
