Quadlogic Controls Corp

What Quadlogic Controls Corp does

Quadlogic Controls Corporation, founded in 1982 and headquartered in Long Island City, New York, designs and manufactures revenue-grade electrical submetering systems used by property owners, building operators, and local distribution companies to bill tenants and manage energy consumption. The product portfolio centers on the QBrick family (QBrick 1, QBrick 4, QBrick 6), the high-density miniQloset residential submeter, the legacy S-10T in-unit submeter, and the Qlic E-Meter 400 multi-channel non-revenue-grade monitor. Meters communicate via Modbus RTU over RS-485 (with optional QRadio wireless) and aggregate into the QTao G2 Data Hub, which reads up to 480 metering points and exposes data through the QView web portal. Devices support Modbus TCP and BACnet for integration with building automation systems and meet standards including NYPSC, Measurement Canada, California Division of Measurement Standards, Maryland PSC, ANSI C12.20-2010, and ASHRAE 90.1-2016.

The company operates a hardware-first go-to-market with a multi-tier distribution model: regional sales representatives cover discrete US/Canada territories, certified contractors handle installation and commissioning, and direct sales support enterprise customers. Pricing is quote-based with a 30-day payment term; revenue is generated primarily through one-time hardware sales supplemented by professional services (installation, commissioning, advance replacement, and warranty/RMA support). Notable customers include Tishman Speyer, the Empire State Building, General Growth Properties, Macklowe Properties, and international deployments in Ecuador, Canada, and Costa Rica.

Following its July 20, 2022 acquisition by Metergy Solutions Inc., Quadlogic operates as the hardware division of one of North America's largest submetering providers. In June 2026, Quadlogic's billing and field services were rebranded under Metergy Solutions, while hardware design, manufacturing, and sales continued under the Quadlogic name. The firm's revenue, headcount trend, and financial performance are not publicly disclosed.
