Buildings use about 40% of global energy. Xandar Kardian is leading the way in lighting & HVAC automation via real-time 99.99% presence/vacancy detection of occupants using radar technology.
Are buildings doing all that they can to reduce energy consumption? Unless you are in an elite class of smart buildings, likely not. Energy costs only represent 1% of the overall cost of doing business while staffing costs can be up to 85%.* The balancing act of ensuring occupant/customer comfort while reducing energy costs can be completely avoided. Xandar Kardian’s UWB radar sensors are the world’s most proven, commercially deployed presence/vacancy detection systems with 99.9% accuracy in real-time.
I have motion sensors in my building. Why should I care?
First, let’s talk numbers. 30-45% of a building’s energy use is devoted to heating & cooling. Anything that can optimize that can provide immediate ROI. PIR motion sensors are inexpensive ($30-$100 per sensor) and are easy to install. Good enough? It comes with a sacrifice.
Xandar Kardian Radar Sensor Difference.
PIR Motion Sensor: 15-45 minutes
PIR motion sensors may claim “99% presence detection” but will rarely say the same for vacancy detection. However, if you think about it, it’s really the vacancy detection that helps to fully automate various building controls. Elevators, lights, HVAC systems can all be automated properly, without causing any discomfort for occupants. Janitorial services and security patrols can also be optimized if occupancy information – including when, how many and how long someone was using a space (ie: toilet/co-working desk/meeting room) is available in real-time.
Xandar Kardian Sensor: 20-40 seconds
Xandar Kardian’s radars are designed to detect presence at 99.9% accuracy within 1-3 millisecond. More importantly however, it can sense and confirm vacancy within 20-40 seconds (delayed on purpose to compensate for occupant who many be going through sleep apnea whereby they are not breathing for 30 seconds).
Alternatively, PIR motion sensors just simply doesn’t know when a space is completely vacated. If someone exited the space, it will start the countdown – sometimes 5 minutes, 15 minutes or even 30 minutes to ensure that lights and HVAC systems stay on in case someone is still occupying the space.
Even in one office room scenario, it could mean the difference of 135 seconds of lights & HVAC being left on (with Xandar Kardian radar sensors) vs. 270 minutes, or 4.5 hours (PIR motion sensors based on 30 minute vacancy timer).
Presence and Vacancy Detection – Anywhere.
Designed to cover a large space (650 sq. ft.). Senses breathing patterns anonymously up to 10 meters with 130° FOV angle. Get real-time occupancy data including when (time stamp), frequency (how many times) and dwell time.
Designed for short distances (max 2M) with narrow 20° FOV angle. This sensor is ideal for sensing occupancy at a desk (installed under the desk or over the desk) and above a washroom stall. Get real-time occupancy data including when (time stamp), frequency (how many times) and dwell time.
You can’t hide your heartbeat.
Xandar Kardian radars are able to detect human presence and confirm vacancy in any type of environment or scenario. In fact, Xandar Kardian has deployed its presence detection sensors in international airports, banks, prisons and high-security office towers around the world since 2017.
