Our Team

Ian Harrison

CEO and Founder 303.916.5212
Ian holds electrical and electronics degrees from City University, London and Economics and Philosophy degrees from Regis University in Colorado. He brings his 25 years of international business experience and large scale program management skills as a senior partner at Deloitte ensuring that Building Energy Performance offers a comprehensive service while remaining practical in its advice and approach. Ian’s strong advocacy on climate change issues and work with the Colorado Renewable Energy Society and visits to Washington D.C. to lobby with the Conservative Caucus of Citizens Climate Lobby led to the creation of Building Energy Performance as a practical way to reduce carbon emissions. It was his experience working on historic building restoration in London during the 90’s where he first identified that energy efficient retrofits were technically possible but often not pursued because of financing challenges and perceived project complexity. As a strong believer in the power of markets to solve problems like global warming, Ian created Building Energy Performance to help building owners and businesses reduce energy bills to pay for essential infrastructure upgrades.
