Operational Excellence
Energy Efficiency in Operations
Belimo stands for energy-efficient HVAC field devices, and so do its operations and buildings.
The stakeholders of Belimo expect the Company to run energy-efficient operations, whether it be in production processes or, even more importantly, in its buildings. With this in mind, Belimo focuses its efforts on reducing its environmental footprint in its very own buildings – where it considers itself most qualified and where it achieves the most significant impact.
Energy Consumption and In-House Production
Energy Consumption Overview
The trend toward renewable energy sources continued during the period under review. In 2022, renewable electricity accounted for as much as 55% of energy consumption, becoming the largest source of energy for the Group. This was mainly due to Belimo switching to 100% renewable electricity at its Hinwil (Switzerland) site earlier in the year.
The Danbury (CT, USA) and Hinwil sites combined account for approximately 85% of total energy consumption within Belimo (refer to the GRI Content Index for more details regarding energy source composition).
Meanwhile, in-house energy production in the form of photovoltaic installations was 828 megawatt hours (MWh), resulting in a contribution of 8.5% to total energy consumption (included in renewable electricity).

GHG Emissions from Scope 1 and 2
Belimo achieved its initial target of reducing greenhouse gas (GHG) emissions in Belimo-owned buildings (Hinwil and Danbury, in relation to the 2019 output) by 25% ahead of schedule during the year under review. The major contributions to these savings came from HVAC projects at our Hinwil and Danbury sites, where we upgraded or replaced the existing systems, and the switch to 100% renewable electricity in Hinwil. Another focus that helped us run our buildings more efficiently was the replacement of the existing lighting with modern LED lights and the employment of daylight-dependent controls. Currently, around 50% of the lighting in Hinwil has already been replaced.
This successful early achievement of our sustainability target has led us to adopt a new reduction target of achieving a 80% reduction in GHG emissions in Belimo-owned buildings by 2025 (Hinwil and Danbury, in relation to the 2019 output, see center graph).

Greenhouse gas intensity, measured in tCO2e per CHF 100 million of net sales, has meanwhile decreased once again in 2022 due to more renewable electricity sources and the double-digit sales growth.
Emissions from Scope 3: Business Travel
During the reporting period, 211.9 tCO2e of emissions per CHF 100 million of net sales resulted from air travel by Belimo employees. In comparison with pre-COVID-19, business travel activity continued to be slightly muted:

Extending Our ISO Certifications
Most Belimo sites are certified pursuant to the international environmental management standard ISO 14001 and quality management standard ISO 9001. During the reporting period, Belimo also introduced ISO 45001 – occupational health and safety management system standards – and added Shanghai as the first audited site. The other sites are to follow.

The Großröhrsdorf (Germany) and the Mumbai (India) sites will also be certified according to ISO 14001. In 2022, the Mumbai site was added to the building management system, which allows Belimo to display, supervise, and collect data from its premises (read the story here). In the future, Mumbai will also be certified according to ISO 9001.
All sites also undergo regular audits by the Swiss Association for Quality and Management Systems (SQS) and the China Quality Certification Center (CQC) in China.
Belimo relies on its building management system that allows the company to display, supervise, and collect data from all sites. This ensures its premises are managed in the best possible manner and achieves transparency as to where all the different forms of energy are being used, including energy demand, recycling, and waste. The collection of this data therefore paves the way for the introduction of tailor-made local energy-saving measures. Belimo also strives to continuously improve energy consumption and reduce waste in production, in accordance with lean management principles, by continually analyzing the energy used in production processes at its sites.
Belimo tracks the following key performance indicators to gauge the success of managing energy efficiency in operations:
- Number of ISO 14001, ISO 9001, and ISO 45001-certified Belimo sites.
- Passed audits by the Swiss Association for Quality and Management Systems (SQS) and the China Quality Certification Center (CQC) in China.
- Percentage of modern LED lighting in Belimo facilities.
- Energy sources (renewable/non-renewable).
- Total energy costs in CHF and energy costs in percent of net sales.
In-house energy production:
- Installed Megawatt Peak (MWP) of photo-voltaic installations and its share of total energy consumption in Megawatt hours (MWh).
tCO2e of emissions:
- Direct from owned or controlled sources – scope 1.
- Indirect from the generation of purchased energy – scope 2.
- Caused by air travel by employees – part of scope 3.
Energy and CO2 intensity:
- Total tCO2 emissions and tCO2 emissions per CHF 100 million of net sales.
- kWh and kgCO2e per CHF 1’000 of net sales, per employee, and per actuator sold.
Recycling and disposal:
- Metric tons for recycling, incineration, and hazardous waste (electronics and separated materials).
- Cubic meters of wastewater.
