Building Automation Solutions

Bringing comfort, safety, and energy savings to people, buildings, and communities with solutions to connect, protect, and conserve.

By connecting HVAC, Building Security, Fire & Safety, and Lighting equipment via networks, buildings can be made more convenient, secure, and energy efficient. Renesas leverages advanced connectivity, sensing, user interface, and low-power technology to enable a new dimension in building automation.
In addition, it is now possible to introduce IDT products. We believe that advanced sensing technology can improve air quality and contribute to the realization of comfortable building spaces.
