The patent pending ITC Steam System regulates steam temperature from a boiler or third party utility by providing a well-defined sequence of instructions for the operation of a digital steam pressure controller system. The ITC invention makes mechanical systems even more efficient by further reducing the energy required to produce steam to heat the buildings. The result is that the ITC Steam System is capable of maintaining steam at as little as 160 degrees Fahrenheit, a 52 degree reduction from steam held at 212 degrees.

ITC works with Johnson Controls to install their mechanical systems to make buildings more efficient in their use of resources such as energy, electricity and water. ITC currently utilizes the Johnson Controls FX-16 series controller to power the steam temperature control algorithm; however the ITC Steam System is not limited to this model.

Steam heating systems are used in some types of commercial and multi-unit residential structures. A typical steam heating system includes a boiler from which steam is distributed to multiple steam radiators located throughout a building. Temperature controls for a conventional steam heating system may include only one type of sensor input, such as the temperature of the interior of the building. The ITC steam system includes multiple sensor inputs to facilitate enhanced temperature control of the steam heating system.

The ITC Steam Temperature Control System improves steam heating efficiency by up to fifty percent (50%) by using ITC's patent pending algorithm to reduce steam holding temperature from 212 degrees to as little as 160 degrees, while simultaneously using individually controlled steam risers and an internet-accessible building management system to implement control strategies like night-setback and trend data. ITC currently utilizes the Johnson Controls FX-20 series supervisory controller to provide internet accessibility.

Use of variable volume, variable temperature systems, such as the ITC Steam System, may contribute materially to the Leadership in Energy and Environmental Design® (“LEED®”) Green Building certification process. Accordingly, use of the ITC Steam System may provide measurable performance in one or more of the following LEED credit categories:
Energy & Atmosphere: EAc1 (1 to 10 Points)

Energy efficiency reduces the negative environmental consequences associated with the production and use of energy. As buildings are commonly powered by fossil fuels, energy savings are critical to green building. The EA credit category represents the primary area where the inherent efficiencies of the ITC Steam System can deliver significant positive impact. And as building HVAC systems traditionally use up to a third of a building’s total energy, reduction of steam production and system electrical usage by 25% - 30% can affect overall HVAC system performance by a factor of up to 10% (1-10 Points).
Indoor Environmental Quality: IEQc7.1 (1 Point)

Systems with proper zoning and enhanced control capabilities provide greater occupant comfort and reduce complaints of inadequate thermal comfort. Designing a mechanical system to meet occupant satisfaction through utilization of ASHRAE Standard 55 requirements meets the intent of this credit. The ITC Steam System will help contribute to overall controllability and occupant comfort.
Innovation in Design: IDc1 (1 Point)

Projects that achieve exceptional performance above the requirements set by the LEED Green Building Rating System and/or innovative performance in Green Building categories not specifically addressed by the LEED Green Building Rating System may earn points under Innovation in Design. As the ITC Steam System may be the first of its kind developed to deliberately regulate and actively monitor steam temperature below 212 degrees, following the strategy described in Path 1 of the Innovation in Design of ID credit 1, may meet the requirements of this credit.
