Introduction
Traditional presence detection methods can prove difficult in hospitality environments. Many organizations rely on key card presence to determine whether a room is occupied — but data shows that many guests leave their cards in the switch while away. What does this mean for energy costs? That’s what the operator set out to learn — and improve upon — in two Singapore properties with Xandar Kardian.
Trial Implementation
In April 2018, they installed Xandar Kardian CT500 ultra-wideband radar sensors in guest rooms in its Hotel and Serviced Residences in Singapore. Both properties previously automated HVAC and lighting levels based on key card presence data — which implied each room was vacant for an average of eight hours per day.
With the Xandar Kardian CT500 sensor, management was able to capture reliable, real-time occupancy data, and adjust HVAC and lighting more expediently. The more accurate radar-based sensing showed the actual vacancy rate was an average of 11 hours per day at the Hotel, and 14 hours per day at the Serviced Residences.
Powerful Savings
Based on the pilot data, the Hotel estimated potential savings of ~$60-120 USD per room, per month (~$90-180 SGD).1 These savings represent an ROI of as little to 13-14 months.
The Serviced Residences also saw positive results. After piloting the CT500 sensor in 98 rooms, they realized total savings of $30,608.82 (SGD) per month.2
“Energy usage is too important to leave up to key card data,” says Sam Yang, Co-founder, Xandar Kardian, Inc. “We have been honored to work with CapitaLand on these projects, helping them prioritize energy savings without impacting their guest experience.”
Meet the CT500
This sensor uses ultra-wideband radar to offer a precise, private way to detect presence in real time throughout your entire facility — helping you strike the perfect balance between comfort and efficiency.
