St Michael's Resort, Falmouth: a 26.1% saving at a luxury spa hotel
An iconic Cornwall hotel renowned for its luxurious accommodation, food and spa facilities, with operators known for a forward-thinking approach to environmental sustainability and wellness.
The challenge
The hotel's annual spend on gas was around £70,000, a significant operational expense. The operators wanted to cut energy consumption without any compromise to the standards and luxury service their guests expect, in line with their sustainability and cost reduction targets.
What we did
After a short site visit, the system was installed with a guarantee of at least a 15% saving on heating and hot water costs. There was no downtime on the heating and hot water system, access was only required in the plant rooms, and hotel and spa operations ran without disruption.
The result
Measured per degree day per guest, and excluding the roughly 27,000 kWh of gas used for cooking each month, fuel use fell by 26.1% across the site: comparing December–August year on year, consumption dropped from 808,021 kWh to 662,075 kWh and the gas bill from £34,149.33 to £25,231.98. That is £8,917.35 saved in eight months, with the full-year saving estimated in excess of £20,000.
How this was measured: the client provides monthly energy usage data, adjusted for degree days and occupancy numbers. Each month is compared with the same month of the previous year to give a kWh per degree day per guest figure, so weather and guest numbers can never flatter the result.
The V1 system is the OH4 Energy Saving System, so client quotes and the full case-study documents refer to it as OH4.
