Next month Siemens Building Technologies will begin a six-month, $2.7 million project to install HVAC, lighting, and control systems upgrades in government buildings in Pitt County, N.C. And through a performance contract, the project won’t cost the county anything upfront.

The upgrade will be paid for through a 12-year performance contract that allows Pitt County to avoid upfront capital expenditures and pay for the project’s costs throughout the course of the contract using the savings achieved through increased energy and operational efficiency. Over that 12-year period, Siemens estimates the improvements could save the county $3.7 million in energy and building operations costs.
