Christian Cianfrone

Co-founder and Chief Decarbonization Officer

Christian is a mechanical engineer and a subject matter expert in building energy efficiency and modelling, with over 15 years of experience that includes leadership positions in consulting, non-profit, and construction. As a consultant, Christian led one of Canada’s largest building performance groups as it consulted on hundreds of projects across North America and developed award winning energy policy for various levels of government. Christian then went on to support the City of Vancouver in building Canada’s first Zero Emissions Centre of Excellence, serving as its first Executive Director and tripling its core funding and staff in its 3 year start-up phase. And finally, prior to joining OPEN full time, Christian co-led the development of EllisDon’s climate targets and advised internal project teams and clients on building decarbonization across multiple building sectors from affordable housing to commercial to large social infrastructure.

As part of the leadership team at OPEN, Christian oversees the company’s strategy and implementation on its building and data science initiatives, which underpin our products.


Our team has decades of experience in green building innovation, software development, and business development.

With executive and management level experience in policy-making, real estate development, property management, architecture, energy modelling, product management, and business management, we have a holistic understanding of the building sector and the leverage points to create positive change.

OPEN Technologies grew out of the OPEN Green Building Society, a non-profit organization that has been developing open source software tools for the green building space since 2013. Today, OPEN Technologies and OPEN Green Building Society are affiliated organizations with a shared goal: to use data to shape a regenerative future for our cities.
