Marc Rosenbaum

Principal, Energysmiths

Marc Rosenbaum, P.E. uses an integrated systems design approach to help people create buildings and communities which connect us to the natural world, and support both personal and planetary health. He brings this vision, experience and commitment to a collaborative design process, with the goal of profoundly understanding the interconnections between people, place, and systems that generate the best solution for each unique project. Design practiced at its highest level goes beyond efficiency and conservation to create places that regenerate and nurture the natural world and all of its inhabitants.

Current areas of concentration include Passive House design, Deep Energy Retrofits, and Net Zero Energy buildings.

He has been published in ASHRAE Journal, Fine Homebuilding, Northeast Sun, Solar Today, Journal of Light Construction, and Northwest Builder, and is a member of the Advisory Board of Environmental Building News.

He is a frequent speaker on sustainable design and has been a featured presenter at many conferences, with audiences that include architects, engineers, construction professionals, facilities managers, planners, educators, utility professionals, and those working in the public sector.

An experienced and enthusiastic teacher, he has trained thousands of professionals and especially enjoys working with students. He holds BS and MS degrees from MIT, where he studied mechanical engineering. He is a licensed engineer in NH, VT, MA, and ME, a Certified Passive House Consultant, and is a LEED Accredited Professional.

Projects of his have won awards from the Northeast Sustainable Energy Association (NESEA – four times a winner), ASHRAE (twice a winner), and the Energy Efficient Building Association (EEBA). Three of his projects have been on the American Institute of Architects (AIA) Earth Day Top Ten list. The French Wing for the Society for the Protection of NH Forests earned a LEEDTM Gold certification, the first LEEDTM certified project in New England.

In his practice of sustainable design consulting, he has worked for institutional clients such as MIT, Vermont Law School, Yale, Dartmouth College, Cambridge School of Weston, and Middlebury College; non-profit clients such as the Society for the Protection of NH Forests and the Woods Hole Research Center; commercial clients such as Stonyfield Farm, Inc., Tom’s of Maine, and the Hanover Consumer Co-op; cohousing groups such as Pioneer Valley, Pine Street, Island Cohousing, Peterborough, Cobb Hill, and Alchemy Farm; with many architects including William McDonough Architects, Maryann Thompson Architects, Kaplan Thompson Architects, Solar Design Associates, Bruner Cott Associates, Coldham & Hartman Architects, Moore Ruble Yudell, and Payette Associates.
