Our web-based building automation systems control and maintain a building’s internal environment. Utilizing BACnet controllers, designed to monitor and control the mechanical systems in a building, OAESYS delivers an open protocol system that is user friendly.


OAESYS utilizes products powered by the Niagara Framework.  Through the use of fundamental Internet software standards and open industry standards, the Niagara Framework creates a common environment that connects and shares information among heterogeneous devices, legacy systems, open system protocols - such as BACnet®, LonWorks® and Modbus™ - the Internet and enterprise information systems.


OAESYS helps our customers implement control solutions to reduce Energy consumption and improve Operational efficiencies.  We help our customers develop project goals that are aligned with their business goals and are financially justified.
