Rethinking HVAC Design with the Thermal Gradient Header (TGH)
How it works
Outdated HVAC design practices rely on gas for heating and electricity for cooling — an approach that, when applied to modern carbon reduction goals, often leads to excessive electrical consumption. The industry has largely overlooked the opportunity to create systems that capture and reuse the abundant thermal energy already present within large buildings.
Since energy cannot be created or destroyed, the Thermal Gradient Header (TGH) solution simply recirculates and reuses this energy, maximizing efficiency with minimal components. Our mission is to help building owners achieve more — with less.
Fewer Components, Lower Costs Fewer components mean lower capital costs — but how? By designing HVAC systems that perform both heating and cooling functions with the same equipment. In a TGH-enabled design, the chiller becomes the building’s primary heater. The same cooling coil also serves as the heating coil, and the exhaust heat reclaim coil doubles as the heat rejection coil.
Where a conventional design might require 500 GPM for cooling and 300 GPM for heating, a TGH system can achieve both with just 250 GPM. This reduction in flow translates to smaller piping, smaller pumps, and significantly lower first costs — all while improving overall system efficiency.
Adaptable to Climate Change and Future Loads Concerned about climate change and rising cooling demands? Worried you’ll need to invest in larger coils, pipes, and pumps to keep up?
With the TGH approach, that’s no longer necessary. The system repurposes your existing heating coils — which typically sit idle during summer — to function as precooling coils.
This intelligent reuse of infrastructure allows your existing coils, pumps, and piping to handle increased cooling loads without expensive equipment upgrades. The only addition required is a heat reclaim chiller. And because the exhaust coil now serves as your heat rejection coil, there’s no need for an additional cooling tower. A Smarter Path Forward
In essence, the Thermal Gradient Header transforms how buildings manage energy. By reusing thermal energy already available within the system, it reduces capital costs, simplifies design, and dramatically improves efficiency. The result is a smarter, more resilient HVAC strategy — one that aligns with both economic and environmental goals. TGH helps building owners do more with less — lower costs, lower carbon, and higher performance from the same infrastructure.
