This session will unveil a detailed framework for step-to-step technical and financial assessments that are essential for crafting and implementing a sucessful decarbinization strategy.  The technical assessment will focus on energy efficiency, renewable integration, electrification, and deep retrofitting, while financial analysis will cover capital allocation, investment returns, and leveraging green financing mechanisms.  The highlight of the presentation will be an in-depth case study of a 800,000 square feet building located in GTA Canada that is undergoing a rigorous decarbonization process.  This case will provide tangible insights into the practical challenges and solutions encountered during the transition, including stakeholder engagement, regulatory compliance, and the use of innovative technologies and business models.
