The challenge
High baseline use, and no way to see where it was going
As part of their ongoing commitment to sustainability and operational excellence, Sankara Hotel (Marriott Bonvoy) partnered with Best.Energy to deploy Eniscope for comprehensive energy monitoring via an award-winning IoT-based optimisation platform.
Before implementation, Sankara was facing high baseline energy use across key areas of the hotel, such as HVAC, laundry and kitchen ventilation. The hotel had limited real-time visibility and control over its energy usage, so it was unable to identify when and where efficiencies could be made.
The solution
Installed with minimal disruption to the hotel's day-to-day
Eniscope was implemented with minimal disruption to the hotel's activities, providing real-time energy monitoring on main incomers and critical zones, and enabling IoT-based duty cycling and temperature control in the laundry and kitchen.
The sequencing and control of Chiller 1 and Chiller 2 was optimised, with ongoing oversight from the Best.Energy Virtual Energy Management team.
What changed
Four interventions across the hotel
Laundry and kitchen control. IoT-based duty cycling and temperature control trimmed run-time in two of the hotel's most energy-hungry departments.
Chiller sequencing. Chiller 1 and Chiller 2 were sequenced and controlled together, balancing load across the hotel's high-use zones.
Virtual energy management. The Best.Energy Virtual Energy Management team kept watch on the data, flagging inefficiencies as they appeared.
Operational and behavioural change
Energy efficiency as a shared responsibility
Alongside the Eniscope energy management system and IoT Air sensors, Sankara Hotel adopted key principles from the Energy Conscious Organisation (EnCO) framework, including engagement, training and behaviour-driven interventions. Staff were made aware of energy-saving opportunities in their daily routines, and with the insights and data from Eniscope, operational schedules were refined to reduce waste.
These cultural shifts, combined with actionable insights from Eniscope, helped embed energy efficiency as a shared responsibility across departments. The result was a more informed and responsive approach to energy management, supporting long-term savings beyond the initial technical interventions.
The results
A fifth off the hotel's energy use
The hotel achieved a 20% site-wide energy reduction, tangible progress toward its environmental and cost-efficiency goals.
Load is now balanced more intelligently across the chillers and high-use zones, and the operations team has better control and earlier detection of inefficiencies than before.
“The Eniscope system has given us greater visibility into how energy is used across the hotel. With ongoing support, we've been able to identify areas for improvement and operate more efficiently.”
