Energy Management

Management Approach

Although Belimo's production is not considered energy-intensive, managing energy use within its operations remains a key lever in reducing the Group's environmental footprint. Belimo is committed to improving the energy efficiency of its manufacturing operations, processes and buildings, thereby reducing its energy intensity per product sold.

Belimo relies on its building management system to monitor, display, and collect data from its Production and Logistics/Customization sites. This system ensures efficient facility management and provides transparency across energy sources. The collected data lays the basis for implementing customized, location-specific energy-saving measures.

Belimo continuously strives to optimize energy consumption in its production operations, guided by lean management principles. This includes ongoing analysis of energy usage across its production sites, as well as driving technical and behavioral energy-saving measures:

• Technical measures include upgrading or replacing HVAC systems with more energy-efficient solutions, transitioning to LED lights, and installing electricity meters to pinpoint areas with further savings potential.

• Behavioral measures include raising internal awareness through communication campaigns that highlight each employee’s contribution to reducing Belimo's overall energy consumption.

In addition to reducing energy consumption, especially from non-renewable sources, Belimo is increasing its share of renewable energy. This includes increasing the proportion of purchased renewable electricity and expanding in-house electricity production through photovoltaic installations.

Energy Consumption in Own Operations

Data externally assured (limited assurance)

In 2025, Belimo consumed 15 828 megawatt hours (MWh) of energy (2024: 13 800 MWh), reflecting an increase of 14.7% compared to the previous year. Primary energy conversion accounted for 17% of Belimo's total energy consumption, which included natural gas (14%) and diesel for Company-owned vehicles (3%). Electricity and district heating/cooling account for 67% and 15% of energy consumption respectively.

Natural gas consumption at our manufacturing site in Danbury, US, decreased slightly despite higher overall production volumes. Belimo continues to pursue its ambition to further reduce dependency on fossil fuels. This includes conducting detailed energy‑saving audits and implementing targeted measures aimed at lowering total energy use. Key actions focus on reducing natural gas consumption at sites in the US and Germany, as well as decreasing diesel usage in the US and India. Diesel is used for backup power generation during blackout situations as well as fuel for company vehicles.

The conversion factors used for reporting energy consumption (including the source) can be found in the Sustainability Notes.

Renewable Energy Share

Data externally assured (limited assurance)

In 2025, renewable energy consumption increased significantly, rising to 57% of Belimo's total energy use (2024: 41%). Focusing on electricity alone, Belimo achieved a share of 85% renewable electricity in 2025 (2024: 59%).

Photovoltaic installations (PV) at Belimo's Production and Logistics/Customization facilities contributed 9% or 1 432 MWh to total energy consumption (2024: 10% or 1 335 MWh).

Energy Intensity

In 2025, the energy intensity of Belimo's operations per CHF 1 000 Group net sales was 14.12 kWh (2024: 14.62 kWh), representing a decrease of 3.4% compared to the prior reporting period. The energy intensity of Belimo's operations per product sold was 1.42 kWh (2024: 1.39 kWh), an increase of 2.5% compared to the prior reporting period. This upward trend is primarily attributable to higher production capacity and net sales growing at a faster rate than the corresponding energy demand for manufacturing Belimo field devices.
