Bob Quitadamo

Bob developed and directs e3i’s Mechanical Group, providing consulting services for mechanical engineering, energy efficiency design and analysis.

He is responsible for reviewing clients’ buildings/facilities/campuses and assessing their needs for mechanical and energy solutions while providing a roadmap for achieving these goals. Bob seeks ways to reduce energy consumption and increase energy savings. What is the right mechanical system for this particular application? What is the most efficient? Where are there utility incentives? What is the life cycle costs? What is the cost/benefit analysis for each application? Taking a deep dive into each and every problem and coming up with the right solution is what gets Bob out of bed in the morning. When he is not working, you can likely find him somewhere in the great outdoors: golfing, playing soccer, skiing, snowboarding, hiking, camping, fishing, or any other outdoor sport you can think of!
