romstyring

Romstyring, ofte kalt romkontroll, refers to systems and practices for regulating environmental conditions and devices within a single room or defined zone as part of building automation. The aim is to maintain occupant comfort while optimizing energy use and operational efficiency. A romstyrings system typically combines sensors, actuators, controllers, and user interfaces to manage heating, cooling, ventilation, lighting, and shading at the room level.

Key components include temperature and humidity sensors, occupancy sensors, CO2 sensors, actuators for HVAC dampers or valves, light dimmers, shading controls, and a room controller or thermostat. Control strategies range from simple on/off to continuous PID control, with setpoints that may be fixed or adaptive. Occupancy-based or demand-controlled ventilation and lighting, as well as scheduling, allow operation to respond to actual use and occupancy patterns. Romstyring can be integrated with a central Building Management System (BMS) or operate as a standalone room solution, and may support standard communication protocols for interoperability.

Benefits of romstyring include improved occupant comfort, reduced energy consumption, and extended equipment life through more precise control. Challenges include ensuring interoperability between devices from different vendors, the initial installation cost, ongoing maintenance, and privacy concerns related to occupancy sensing and data collection.

Standards and protocols frequently used are KNX, BACnet, and LonWorks, particularly in professional or commercial settings, with wireless options such as Zigbee and Wi-Fi for consumer-focused solutions. Applications span offices, schools, hotels, and residential environments, where room-level control complements broader building automation and energy management strategies.
