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!

William J. Leuci

Bill specializes in program development and project management solutions, with expertise spanning business continuity planning, critical infrastructure design, alternative energy systems, laboratory and data center structure designs.

As the founder and principal of e3i Engineers, Bill’s 30+ years of experience encompasses groundbreaking designs such as the nation’s largest rotary UPS system, classified bio-containment facilities, and the integrated testing and commissioning of top-secret supercomputing facilities—achievements realized well before the term “mission critical” gained its modern prominence. Bill spent the early part of his career engineering critical power systems for military installations worldwide, including radar systems, communication networks, and data centers, serving esteemed branches such as the U.S. Navy, Air Force, and NATO, among others.

Connor Harrison

Connor, a proficient mechanical engineer and project manager, excels in collaborating with clients to understand their unique goals and requirements. He implements tailored HVAC solutions and oversees projects from inception to completion.

With over seven years of experience working across the United States, Connor is a seasoned expert in optimizing airflow direction and distribution within buildings. He focuses on two critical objectives: ensuring occupant comfort by maintaining a pleasant indoor environment and safeguarding equipment performance by keeping ambient conditions cool enough to meet manufacturer specifications, preventing overheating and potential catastrophic system failures. Connor excels in project management and bridges the communication gap between non-technical groups and engineers.
