Lucas Toffoli

  • Carbon-Free Buildings

Lucas is a principal in RMI’s Carbon-Free Buildings practice. He coleads RMI’s REALIZE initiative and leads the Advanced Building Construction Collaborative, launched with the support of the US Department of Energy.

The Collaborative brings together and catalyzes the collective efforts of a diverse range of emergent and incumbent building sector stakeholders. It works to accelerate the uptake, scaling, and mainstream adoption of advanced building construction (ABC) — technologies and other innovations for new construction and building retrofits that combine energy-efficient building decarbonization with streamlined, scalable industrialized construction methods — while supporting and leveraging modernization of the US construction industry. The Collaborative’s mission is to drive ABC in service of a decarbonized US building sector by 2045 while improving affordability, resilience, and equity.


Previously, Lucas has supported RMI’s development of New York State’s Carbon Neutral Buildings Roadmap with NBI and NYSERDA.

Before joining RMI, Lucas worked for Cummings Properties, a vertically integrated, design-build-manage real estate development company in the Boston area. There, he led sustainability and energy efficiency efforts across the firm’s portfolio, in addition to performing various operational and construction management roles. He has also worked on commercial development projects for Sares Regis Group of Northern California, a development management firm in the San Francisco Bay Area.

Lucas’ prior professional experience spans business strategy consulting for life sciences clients (including five of the world’s top ten companies in this sector), architecture, building operations, and coaching. He has worked on three continents and in four languages.
