The Entech S2 is a commercial energy management system that helps large buildings cut energy use by up to 35%. Designed for retrofit applications, the S2 platform combines over 20 sensors, zone-level smart thermostats, and a central controller that uses real-time data and adaptive algorithms to optimize HVAC performance. Glassboard partnered with Entech from concept to launch—delivering industrial design, mechanical engineering, electronics development, and firmware integration across the entire platform.

Challenge
Entech set out to reimagine the commercial thermostat. Going beyond a standalone controller, Entech developed a distributed intelligence system that dramatically improves energy efficiency in legacy buildings. The challenge was to develop a robust, scalable hardware solution that could seamlessly interface with existing infrastructure, house advanced sensing and control electronics, and deliver a premium, consumer-like user experience in a rugged, commercial-grade package. All of this needed to be achieved to support pilot deployments and unlock broader market entry.
Solution
Glassboard collaborated closely with Entech to architect a modular hardware system consisting of a central control hub, wireless temperature sensors, and an array of wired sensors. Our team engineered the embedded systems to support BACnet integration, cloud-based control, and low-latency communication across devices. Mechanical and thermal designs were optimized for performance and reliability in high-density commercial environments, all while supporting scalable manufacturing and easy deployment.
Result
The Entech S2 launched as a best-in-class energy management system offering enterprise-grade capabilities with an intuitive, user-centered design. Buildings using S2 have reported energy savings up to 35%, and the system has been rolled out in schools, office buildings, and industrial facilities across the U.S. The successful launch has positioned Entech as a leader in the next generation of intelligent building solutions, with a hardware platform built for scale.
