KNX UK Member, Ryan Sheppard of KNX Ireland comments on the often-overlooked advantages of multi discipline presence sensors:
Control Lighting, HVAC, Security, Health, Shading and more from one sensor.
One of the most interesting device categories on the KNX market, is the Presence Detector. This seemingly simple device is commonly understood to be a lighting function controller and nothing more. However, this is where a KNX Presence Detector differs greatly.
A KNX Presence Detector is used to detect human presence in a specific area. This offers a vast and versatile range of functionality encompassing key building services to include Lighting, HVAC and Security among other features.
Functions and benefits of KNX Presence Detectors in building management include:
Energy conservation: Lighting can self-regulate via dimming or on/off, dependent on room occupancy levels and measured natural daylight. Similarly, the HVAC system can automatically move between comfort & economy mode upon presence detection. Both can help reduce energy consumption resulting in lower energy costs and aligning with BREEAM & LEED certifications.
Security: Room monitoring functions can be carried out by the KNX presence detector with updates sent to the site intruder alarm system thus detecting unauthorised entry to the building and helping to prevent theft or other security breaches. KNX Presence Sensors can also feature a heart-beat function which ensures the device cannot be unknowingly tampered with.
Improved building utilisation: Building managers can gain insights into how spaces are being used. This information can be used to optimise the use of space and improve building efficiency.
Enhanced comfort and convenience: Automating various functions of the building can improve the comfort and convenience of building occupants, while also reducing the workload of building maintenance staff.
