Commercial buildings above 50,000 sq ft run centralized chilled water HVAC systems that account for the majority of electricity consumption. We improve that performance by 15–25% — with no infrastructure changes and no tenant disruption.
In commercial buildings, centralized chilled water HVAC plants run continuously to serve offices, common areas, and tenant spaces. The majority of that energy is lost to thermal inefficiency before it reaches the occupied space.
For commercial buildings, Chillers leads — because chilled water HVAC is the dominant load. FilterPro compounds the savings on all remaining electrical systems. Both deploy without infrastructure changes or tenant impact.
A 12,000 sq ft mixed-use, three-story commercial building cooled by two 60-ton air-cooled chillers operating 24/7 deployed Maxwell nanofluid across its chilled water system. The additive was introduced directly into the existing fluid loop — no hardware changes, no system shutdown, no disruption to occupants.
The result: 16.9% improvement in chiller energy efficiency and 15% overall system energy savings — achieved by improving heat transfer at the evaporator, allowing thermostats to reach setpoints more quickly and compressors to run at lower load. Payback was achieved in 2.2 years, with an annual ROI of 46% over a 10-year period.
The building operator subsequently evaluated Maxwell across the wider property portfolio. The technology has since been included in a major energy company's Proven Technology Database — one of the most rigorous third-party validation processes in the commercial real estate sector.
The commercial building case study led to a portfolio-wide evaluation. The numbers confirm that verified per-site results translate linearly across a multi-building estate.
