About Rundell Engineering
Rundell Engineering was founded to focus on what matters most in complex facilities: reliable operation, clear system behavior, and practical engineering that performs in the real world. The firm specializes in central utility systems, building automation, controls optimization, utility rebate incentive strategy, and capital planning for large, energy-intensive facilities.
Rundell Engineering is headquartered in northern New Jersey and supports projects across the United States, with a primary focus on New Jersey, New York, Pennsylvania, Connecticut, and Massachusetts. The practice is built around system-level thinking and hands-on experience with operating infrastructure, emphasizing practical, repeatable approaches that improve reliability, reduce energy use, and deliver durable performance over the life of the system.
About John Rundell
John Rundell is the Principal of Rundell Engineering and a mechanical engineer with extensive experience in the design, commissioning, and optimization of central thermal and power systems, building mechanical systems, and energy distribution infrastructure. His engineering approach is informed by years of direct exposure to underperforming systems, from large district chilled water, boiler, and cogeneration plants to building- and zone-level controls. In practice, many of the most effective solutions come from unlocking the latent capability of existing equipment through better design and more appropriate control strategies.
John has worked on systems ranging from district steam and campus chilled water plants to hospital, laboratory, university, and pharmaceutical HVAC systems. He teaches building energy efficiency at The Cooper Union and serves on ASHRAE Technical Committee 1.4, Control Theory and Application. Through system optimization and incentive-aligned engineering, he has helped clients secure millions of dollars in utility funding for projects including chilled water plant optimization, building controls improvements, and compressed air system upgrades.
