Swisslog

Client Overview

Swisslog is a global provider of automated logistics and warehouse solutions, supporting organisations with advanced robotics, software and automation technologies. With offices and operational facilities supporting its UK activities, Swisslog recognises the importance of managing energy consumption within its buildings and ensuring compliance with environmental regulations.

To support its sustainability objectives and regulatory obligations, Swisslog engaged Inteb to undertake an Energy Savings Opportunity Scheme (ESOS) Phase 3 audit and action plan submission. The project focused on analysing the site’s energy consumption, benchmarking its performance and identifying practical opportunities to reduce energy use and associated costs.

Client Objectives

Swisslog sought to improve visibility of its energy performance while ensuring compliance with regulatory reporting requirements. Key objectives included:

ESOS Phase 3 Compliance:

• Complete a comprehensive ESOS Phase 3 audit in line with regulatory requirements.
• Assess energy consumption across the site, focusing on electricity and natural gas use.

Energy Performance Assessment:

• Analyse energy consumption patterns to understand how efficiently building systems were operating.
• Conduct a degree day analysis to assess whether heating demand was appropriately managed relative to external weather conditions.

Energy Benchmarking:

• Compare site performance against recognised industry benchmarks to assess operational efficiency.
• Evaluate performance against the CIBSE TM46 benchmark for air-conditioned office buildings.

Identification of Energy Saving Opportunities:

• Identify and quantify practical energy efficiency measures across the site.
• Provide estimated annual cost savings, carbon reductions, energy savings (kWh), implementation costs and payback periods.

Our Approach and Results

Inteb worked closely with Swisslog to gain a clear understanding of how the site operates and how energy is consumed across its facilities.

1. On-Site Assessment and Operational Insight

To support the ESOS audit, our team conducted a site visit to observe the building and operational processes first-hand. During this visit, we:

• Identified and documented high energy using equipment and systems.
• Photographed key assets to support the audit and reporting process.
• Gained valuable insight into the way the site operates, enabling a more accurate assessment of energy use across the facility.

2. Energy Consumption Analysis and Benchmarking

We carried out a detailed analysis of Swisslog’s electricity and natural gas consumption, including a degree day analysis to assess whether heating demand aligned with weather patterns and building usage. The results demonstrated that the site performs significantly better than typical office benchmarks. When compared with the CIBSE TM46 benchmark for air-conditioned offices, the site’s energy use was substantially lower:

• Gas consumption was 149% lower than the benchmark
• Electricity consumption was 229% lower than the benchmark

This analysis confirmed that Swisslog’s building operations were already performing at a high level of efficiency compared to industry standards.

3. Identification of Energy Saving Opportunities

Despite the site’s strong energy performance, Inteb identified four energy saving opportunities to further improve efficiency. Each opportunity included detailed estimates of:

• Annual energy savings (kWh)
• Carbon reductions (tCO₂e)
• Cost savings (£)
• Implementation costs
• Payback period

One notable opportunity involved the installation of a rooftop solar PV system. A 43 kWp solar PV array installed across the South East and South West facing roofs could generate significant on-site renewable energy, delivering estimated annual savings of approximately:

• £9,000 in energy costs
• 26,800 kWh of electricity

Across all identified measures, the average payback period was approximately 4 years, demonstrating strong financial viability.

Conclusion

Through our collaboration with Swisslog, Inteb successfully delivered a comprehensive ESOS Phase 3 audit support, providing the organisation with valuable insights into its energy performance and opportunities for further improvement.

The project highlighted Swisslog’s strong operational efficiency compared with industry benchmarks while also identifying practical energy saving opportunities, including the potential for on-site renewable energy generation.

This case study demonstrates how detailed energy analysis, benchmarking and on-site assessments can help organisations maintain regulatory compliance while continuing to improve their energy performance.
