Case Study

The George & Dragon

Summary

The George and Dragon is an 18th-century hotel and restaurant where energy efficiency is particularly challenging. The building has no mains gas, relies on electric boilers, and features older construction elements such as wooden and single-glazed windows. These constraints make maintaining guest comfort while controlling energy usage difficult.

Challenges

Heat Wastage

Multiple electric boilers were running continuously, making it difficult to control energy usage while maintaining a comfortable temperature in each guest room.

Doors & Windows Left Open

Staff and guests frequently left doors and windows open, causing significant heat loss with no notification system in place to alert the team.

Inconsistent Setpoints

Temperature control relied on radiator valves and varied from room to room, resulting in guest comfort complaints and unnecessary overheating.

Solution

Mammoth installed hardware within the guest rooms to control the heating system while giving guests an easy and intuitive way to adjust temperatures.

Our software continuously monitors and optimises performance to ensure energy efficiency while keeping guest comfort at the forefront. Integration with the hotel's booking system enables automatic optimisation based on occupancy, reducing waste in empty rooms.
