Daniel Thwaites

KBR Case Study

At Daniel Thwaites, sustainability isn’t just a goal—it’s becoming part of the operation. To push energy efficiency, a trial involving advanced energy-saving solutions was conducted at the Crown Inn and Toll House, two historic sites celebrated for their hospitality. From cellar management to fridge optimisation, every measure was carefully implemented, monitored, and refined to make a measurable difference in power consumption without compromising quality.

Cellar Manager Optimisation

With the installation of the Cellar Manager on the cooling systems, the average daily power usage was reduced from 54.15 kWh to just 33.80 kWh. This impressive 37.5% reduction demonstrates the effectiveness of the Cellar Manager in significantly easing energy consumption while maintaining ideal cellar conditions.
