Sirus is an Irish company that specializes in providing HVAC, BMS, and Energy Efficiency Solutions and Services for buildings. With its headquarters in Ireland, Sirus has been in operation since 1988. The company originated from the merger of two separate entities: an HVAC company called Temperature in Cork, and a BMS company called Compute Systems in Dublin.

The merger was driven by the growing demand for building management systems that control HVAC equipment and manage energy usage. Today, Sirus has grown significantly and employs over 120 staff members who specialize in delivering critical environments to sectors such as pharma, biotech, and data centers. In 2018, Sirus became a majority-owned subsidiary of SAUTER, a global leader in building automation technology.
