Cutting energy costs in half: resounding success for a renowned global distiller

Glenmorangie, a renowned Scottish whisky distillery and part of the Louis Vuitton Moët Hennessy (LVMH) group, faced high energy costs and fluctuating temperatures at its bottling facility.

Despite having a Building Energy Management System (BEMS), Glenmorangie sought a more focused solution to improve energy efficiency and reduce costs. By working closely with the team at Zenergi, the strategic execution resulted in significant savings- a 59% reduction in electricity consumption and a 52% reduction in gas usage.

Challenge

Glenmorangie’s bottling facility in Alba, Livingston, was facing high energy costs and inconsistent temperature control across the site. While a Building Energy Management System (BEMS) was in place to centrally manage energy use, Glenmorangie sought a more focused solution to improve energy efficiency, reduce costs and create a more comfortable environment for staff and visitors.

Solution

Zenergi installed an Automatic Monitoring and Targeting (AM&T) submetering platform. The aim was to track temperatures and energy consumption and identify efficiencies.

Key findings

We quickly discovered that temperatures were regularly exceeding 25°C, largely due to the location of wireless temperature sensors across the site. By relocating these sensors, we achieved an immediate 6% reduction in gas consumption through better temperature control.

Next, we assessed the compressors, which included both large and small compressors which were manually switched depending on demand. We found that the large compressor was left on for a longer period than required. By adjusting the controls we reduced excess energy consumption from the compressors.

Additionally, during the site closure due to the COVID-19 pandemic, we worked closely with the site team to minimise energy consumption by ensuring the building, compressors and air handling units (AHUs) were reduced in line with occupancy.

Results

Through these targeted control optimisations, Glenmorangie benefitted from improved comfort for occupants within the facility and significant energy savings:

• 59% reduction in electricity consumption
• 52% reduction in gas consumption
