Background

About Guy Kosmin

I’m a mission-driven decarbonization leader with 15+ years of experience delivering large-scale, high-impact sustainability and energy efficiency initiatives across commercial, industrial, and government sectors. At the intersection of engineering, technology, and environmental stewardship, I’ve built a career on turning complex operational challenges from energy efficiency opportunities into measurable, scalable solutions that drive sustainability. From managing $40M energy retrofit projects and deploying Energy Management Systems (EMS), to leading AI-powered building optimization strategies for 50M+ square feet of real estate, my focus is clear: accelerate decarbonization. I’ve led cross-functional teams that span engineers, architects, data scientists, and customer success professionals, all with a shared goal of reshaping how buildings perform and contribute to a cleaner energy future. My work has delivered: ≠ 5–20% energy savings through AI-driven efficiency strategies ≠ Consistent 5% quarterly energy reductions in a LEED Platinum building ≠ 30% energy cuts and $1M+ annual savings on Historic Federal Buildings ≠ $15M+ in annual recurring revenue through customer adoption and expansion of Proptech My technical toolkit includes AI/ML applications in smart building technology, BAS SOOs, ECM implementation, financial modeling / LCC analysis, and enterprise-level sustainability reporting. What sets me apart is my ability to translate vision into execution. Whether launching new clean tech pilots or streamlining smart building platform integrations by 50%, I bring strategy, structure, and systems thinking to every initiative I lead. I hold advanced certifications including PMP, CEM, REP, and LEED AP, underscoring my commitment to excellence in both project delivery and decarbonization. Looking ahead, I’m passionate about scaling intelligent decarbonization systems that balance performance, sustainability, and cost. I thrive in environments where innovation meets real-world application and where the next leap in building technology is always just around the corner.
