Challenge

Marsham Court Hotel was operating with limited insight into the relationship between energy consumption and operational factors like occupancy levels, weather conditions, and time of day. The property needed to understand where energy was being used unnecessarily and how to address inefficiencies without disrupting guest services or requiring significant capital investment.

Solution

Fewton deployed whole-building electricity and gas meter analysis, uncovered significant efficiency opportunities, and is now installing sub-metering to support implementation of initial recommendations.

The approach includes:

• Analysis of half-hourly electricity and gas consumption data alongside occupancy and weather patterns, benchmarked against CIBSE values, to establish baseline inefficiencies.

• Installation of sub-meters on major energy-consuming equipment including heating systems, kitchen equipment, ventilation, and lighting circuits to enable detailed monitoring.

• Delivery of initial recommendations to the engineering team targeting heating controls, kitchen equipment scheduling, and ventilation optimization.

• Deployment of real-time alerts for anomalies including baseload breaches, unexpected peak loads, and portable heater usage patterns.

• Ongoing collaboration with the hotel's engineering team to implement recommendations and validate results through continuous monitoring.

Results

Up to 18% electricity savings and up to 27% gas savings identified, with Fewton actively managing implementation as an ongoing process.
