What Linnean Solutions does

Linnean Solutions is a Cambridge, Massachusetts-based sustainability and climate resilience consulting firm founded in 2010 and operating as an LLC under founder Jim Newman. With a team of approximately six professionals holding credentials such as Certified Passive House Consultant, PHIUS Certified Passive House Consultant, and LEED AP, the firm delivers climate vulnerability planning, Passive House and high-performance building consulting, Living Building Challenge advisory, embodied carbon analysis, energy dashboard deployment, and resilience assessment services.

The firm's clients span Massachusetts municipalities (Medford, Somerville, Portland/South Portland, Amherst, Harvard, Bolton, Devens, Hudson, Natick, Framingham, Providence), educational institutions (Williams College, Boston Architectural College, charter schools), real estate developers and owners (Hillside Center, Clippership Wharf, Hebrew SeniorLife, Vitality Estates), and nonprofits (Newport Restoration Foundation). Strategic engagements include the redesign of the Massachusetts Municipal Vulnerability Preparedness (MVP 2.0) program for the Executive Office of Energy and Environmental Affairs, co-development of the Massachusetts Healthy Soils Action Plan with Regenerative Design Group, and co-authorship of the Ready to Respond resilience manual with Enterprise Community Partners and the Resilient Design Institute.

The business operates as a project-based professional services practice with sales-led, direct engagement. Revenue is generated through consulting fees for municipal climate plans, PHIUS certifications, energy dashboards, and resilience assessments, with no external funding and no disclosed recurring subscription product. Pricing and engagement size vary by project type, and the firm maintains geographic reach across the U.S. and parts of Latin America while remaining densest in Massachusetts.
