World Energy Innovations is an engineering-driven firm built on one principle: performance must be demonstrated in the field, not assumed on paper. We integrate mechanical engineering, controls, and data-driven analysis to solve complex energy challenges across healthcare, manufacturing, and industrial facilities. We have led low-temperature hot water and steam-conversion work for 46 years, the specialty that makes high-efficiency chillers and electrification possible.
Founded in 1979 by Tom Kiser as Professional Supply, Inc., WEI began with a simple philosophy: solve energy and infrastructure challenges through practical engineering and measurable results.
Early industrial work — including Ford Motor Company facilities — built deep expertise in building systems, controls, ventilation, and energy performance. The company developed Bigfoot positive building pressurization and its first Monitoring & Verification (M&V) capabilities.
From the start, WEI looked at how systems interact and verified that improvements delivered the expected results, rather than simply recommending isolated equipment or individual energy conservation measures.
WEI grew from a regional engineering company into a national and international energy solutions provider. Large-scale, multi-facility programs for clients such as Ford Motor Company proved it could treat entire facilities as integrated energy systems, not collections of single fixes.
M&V matured from documenting initial savings into a discipline for sustaining performance over the life of an investment — and the operational lessons it captured fed directly back into how WEI designed and implemented future projects.
In 2010, WEI launched Powerdigm and introduced the Utility Service Agreement (USA) — a performance-based alternative to traditional customer-funded capital projects.
Under the USA, WEI could invest in and own energy infrastructure, bundling engineering, implementation, performance guarantees, ongoing M&V, asset ownership, and lifecycle management while taking responsibility for long-term performance. Customer-funded delivery remained available for owners whose capital budgets or strategy favored it. Projects such as Ocean Spray showed the full model: design, implement, measure, and stay accountable.
The company also formed a strategic joint venture with Worthington Industries as Worthington Energy Innovations, broadening its resources, reach, and customer base.
Projects increasingly combined heat recovery, combined heat and power, steam-to-hot-water conversion, ventilation optimization, advanced controls, electrification, and emerging technologies such as LightNing into broader facility energy strategies.
Expanding into healthcare and other mission-critical environments meant delivering major upgrades without compromising reliability, resiliency, ongoing operations, or occupant needs. The work reinforced a defining principle: evaluate the whole facility or campus as one interconnected energy system.
In 2021, the company became World Energy Innovations (WEI), reflecting its international reach and the growing scope of what customers asked it to solve. Today WEI serves healthcare, industrial, manufacturing, institutional, and utility organizations.
Its approach is technology-neutral and systems-based. Rather than starting from a chosen product, WEI weighs existing infrastructure, capital planning, energy use, resiliency, maintainability, sustainability goals, and long-term facility plans before owners commit capital to assets that may run for decades. From there it integrates energy efficiency, heat recovery, low-temperature hot water, electrification, decarbonization, controls, ventilation optimization, positive pressurization, distributed energy, advanced lighting, and continuous M&V into a single roadmap.
Recent work spans global manufacturing programs for Schneider Electric and Hero MotoCorp and a campus-wide Super Campus Steam-to-Hot-Water Conversion for Memorial Sloan Kettering Cancer Center, modernizing legacy infrastructure while improving energy performance and resiliency — and named the 2026 Association of Energy Engineers U.S. Energy Project of the Year.
Across these projects, WEI applies the same philosophy it was founded on.
Practical engineering. Disciplined implementation. Measurable results. Sustained performance.
Since 1979, WEI has grown from a regional engineering company into a nationally recognized energy and infrastructure provider serving organizations across the United States and internationally. The technologies have changed and customer priorities have expanded — from energy conservation to resiliency, modernization, electrification, decarbonization, and long-term campus planning.
What hasn’t changed is the approach: understand the whole system, choose the right solution, implement it well, measure the results, and remain accountable for sustained performance.
