Originally Published on Seacoast Online.

Founded in 1992 by James Petersen, Petersen Engineering was a one-person firm for many years. The firm now employs seven including four licensed professional engineers. The core work of Petersen Engineering is the design of HVAC, plumbing and fire protection systems for multi-family, commercial and industrial buildings.

Long known as a leader in sustainability the firm specializes in energy efficiency, renewable energy, integrated design practices, building science and building enclosure technology. In 2010 Petersen Engineering completed a deep energy retrofit on its company's offices on Maplewood Avenue in a historic 1804 federal-style building. The more than 200-year-old building now uses only 30 percent of the energy used by code compliant new office buildings while at the same time not sacrificing modern amenities or the historic character of the building.

Petersen was recently awarded the 2015 Engineer of the Year by the NH Chapter of the American Society for Heating, Refrigeration and Air-conditioning Engineers (ASHRAE) for the firm’s progressive designs and for service to the community. Some of Petersen Engineering's current work includes the upgrades to the Portsmouth wastewater treatment plant on Peirce Island, a 100,000-square-foot addition to the Massachusetts Museum of Contemporary Art in North Adams, Mass., and new construction of the Lewis Gathering Center corporate retreat in Kensington, which expects to achieve Passive House Certification, reducing the energy required for heating a building by 85 percent.

Petersen also does pro bono work, currently designing an expansion of the Seacoast Waldorf School in Eliot, Maine, to serve children pre-K through Grade 8, and designing and managing the replacement of mechanical systems at the Portsmouth Indoor Pool in a public/private collaboration with Save the Indoor Portsmouth Pool and the city of Portsmouth.
