| | JUNE 20258IN MY OPINIONNavigating through the Journey of Energy Efficiency My professional career began with a strong foundation in mechanical and operational fields. After earning my engineering degree, I joined the U.S. Navy as a shipboard engineer, maintaining equipment, managing ship movements, operating turbines, HVAC units and auxiliary systems. The knowledge gained led to a role as Chief Engineer in the U.S. Coast Guard. The responsibilities included overseeing the operation of chillers, modernizing critical energy systems and maintaining mechanical equipment at military facilities. Building on my extensive experience in the U.S. Coast Guard, I led various building modernization projects that involved installing coaching units and upgrading management systems from pneumatic to electric. I also implemented numerous energy improvement technologies and managed large chillers, including absorption, screw and centrifugal types. Later, at Universal Studios, I contributed to large-scale projects that involved executing energy efficiency measures in commercial hotels. Taking up a new position at Hanscom as the Base Energy Manager entailed converting the base’s energy systems from oil to gas and implementing significant lighting modifications. Now at Eversource Energy, I advise retail, hospital and biopharmaceutical customers on energy efficiency. My responsibilities include recommending sustainable solutions and offering incentives for initiatives that lower power grid demand. All these involvements and experiences shape my understanding of energy consumption and help me align with broader environmental goals for the future.Emerging Trends and Technological InitiativesWe are witnessing a transition towards cleaner refrigerants in the field of energy efficiency. We started to incentivize the adoption of carbon-free refrigerants, which aligns with upcoming regulatory changes intended to reduce the environmental impact of refrigeration systems. Additionally, using insulated jackets can save significant energy since most fermenters lack insulation. Sponsoring these new insulated models can greatly enhance energy efficiency.Heat pumps represent a remarkable technological advancement in improving energy efficiency.
