Optimization, grounded in engineering reality.
Energy efficiency doesn’t need to be complex.
It needs to be engineered for the real world.
Rundell Engineering provides mechanical engineering, system design, and operational optimization for complex buildings and campuses. Our work focuses on HVAC, central plants, controls, and utility systems that must perform reliably in the real world, not just on paper.
Our Core Philosophy:
Reliability and performance come first.
The most successful projects start by addressing aging, high-risk systems and equipment that already requires attention or is underperforming.
Energy savings follow from better engineering.
Rather than one-for-one replacements, we look for opportunities to improve system performance through best-practice controls, sequencing, and efficient equipment.
Utility incentives fund the capital.
When energy savings are properly quantified, utility programs can fund 30–75% of project costs, materially improving project economics.
This sequence matters. Reliability enables performance. Performance creates savings. Savings unlock incentives.
Expertise
Central Plant and BAS Design
Engineering design for central plants and building automation systems that improves reliability, performance, and long-term operability.
Controls Optimization and RCx
System-level controls optimization and retro-commissioning to improve performance, reduce energy use, and restore operator confidence.
Owner’s Engineer and Capital Master Planning
Owner-side engineering support and long-range utility master planning to guide capital decisions with clear technical and financial insight.
Utility Incentive Strategy and Energy Engineering
Engineering-driven utility incentive strategy and energy analysis that funds infrastructure upgrades and improves project economics.
Cities are electrifying. Energy codes and carbon regulations are accelerating. Owners are being asked to reduce emissions, improve efficiency, and maintain reliability at the same time.
Regulations such as Local Law 97, BERDO 2.0, and similar policies across the U.S. are reshaping how buildings are designed, operated, and upgraded. This transition is a generational challenge, and it will not be solved by equipment swaps alone.
It requires thoughtful engineering, realistic controls strategies, and optimization approaches that respect how buildings are actually run.
Rundell Engineering helps owners navigate this transition by focusing on proven designs and operational improvements that maximize the performance and long-term value of critical assets.
The built environment is changing.
“There is an even cleaner form of energy than the sun, more renewable than the wind: it's the energy we don't consume.”

*Arthur H Rosenfield is a pioneer in the engineering practice of energy efficiency. A unit of energy conservation known as the “Rosenfeld” is equal to electricity savings of 3 billion kilowatt-hours per year, the amount needed to replace the annual generation of a 500 megawatt coal-fired power plant.
