Success you can measure
Embarcadero Center, San Francisco (USA)
How can you modernise a 40 year old high rise without a major capital investment?
Targeted HVAC retrofit reduces energy use by 28%.
At San Francisco’s iconic Four Embarcadero Center, an aging chilled water system with 2-way pressure-dependent globe valves and pneumatic actuators was struggling with low differential pressure (delta T), rising energy costs, and no visibility into hydronic performance.
Retrofitting the building with Belimo Energy Valves converted the legacy system to pressure‑independent control. The result: improved delta T, real‑time system visibility, and hidden faults brought to light. The upgrade reduced chiller plant energy use by 28%, delivering around $131,000 in annual energy cost savings.

Allseas (Netherlands)
82% energy savings on the high seas: Allseas optimises its fleet with the Belimo Energy Valve™
Allseas, a company with global leadership in the offshore energy sector, is setting new standards in HVAC efficiency. To ensure the sustainable operation of the fleet and the comfort of up to 500 employees per vessel, the heating and cooling systems of the Allseas ships are being gradually equipped with Belimo Energy Valves.
A special highlight of these modernisation measures is the retrofit of the "Pioneering Spirit", the world's largest construction vessel. The vessel, which can raise offshore platforms weighing up to 60,000 tons in a single lift, achieved impressive results by installing 175 Energy Valves: the pumps' current consumption was reduced from 600 kW to 120 kW — an energy saving of 82%.
Thanks to this targeted Belimo RetroFIT+ measure, Allseas is now saving approximately EUR 700,000 in energy costs each year. As a result of these significant savings, the project's payback period is just three years. This means that the company is making a significant contribution to economic efficiency and to the reduction of the ecological footprint of the offshore industry.

Paramount Group, New York (USA)
Belimo Energy Valve™ helps New York City Property Manager cut carbon emissions by 40%
In response to a regulatory mandate starting in 2024 in New York City that focused on improving energy efficiency and reducing CO2 emissions for large buildings, a leading property management company upgraded key buildings with the Belimo Energy Valve™, a pioneering, IoT-enabled device designed to optimise energy consumption in HVAC systems and reliably maintain delta T.
The upgrade dramatically cut energy consumption and costs – saving over USD 1 million on electricity costs in 2023 alone. In addition, Paramount received USD 2.1 million in financial incentives from utility companies for its efforts, aligned its buildings with CO2 reduction goals for 2030, and secured important sustainability certifications. This marks a significant stride towards the 2050 CO2 neutrality target, demonstrating a strong commitment to sustainability and efficiency.

Belimo Office, Großröhrsdorf (Germany)
Gas consumption halved: Belimo's energy savings through retrofitting at Großröhrsdorf site
Belimo is committed to increasing energy efficiency and reducing CO₂ emissions in buildings. An example of our initiative is the upgrade of the heating system at our Großröhrsdorf site in Germany, which covers an area of approximately 19,000m2.
Before our own RetroFIT+ specialists intervened, the site consumed 750,000 kWh of gas annually. Through a series of targeted adjustments and modernisation measures, we successfully halved this consumption, resulting in an annual saving of 75 tons of CO₂.
The payback period was approximately one year, and the annual savings amounted to EUR 38,000.
Watch our video to see the practical steps and technologies Belimo has employed to decrease energy use, lower costs, and contribute positively to the environment.

650 Townsend Building (USA)
Pump energy reduced by 48%
The 650 Townsend Building in San Francisco was built in 1990 as a shopping centre and converted into an office building in 2011. The HVAC system was controlled by a combination of pneumatics and several older DDC systems, resulting in frequent tenant comfort complaints, maintenance issues, simultaneous heating/cooling and high energy bills. After an initial upgrade of the energy management and control system, the building was subjected to a multi-year programme of operational and maintenance optimisations and energy-saving measures. By installing Belimo Energy Valves in 2017, 650 Townsend was able to reduce pump energy by around 48% and significantly improve cooling efficiency.

Casta Diva Group, Milan (Italy)
53% energy savings and higher comfort
Originally built in the 1950s, the Milan headquarters of Casta Diva Group has been converted into a modern office center. It features meeting rooms and audiovisual laboratories. In collaboration with Casta Diva Group’s ESG team, Belimo carried out a major RetroFIT+ project.
The air-conditioning system consists of two independent direct expansion units serving a duct loop system across two floors. A monitoring effort by Belimo revealed temperature imbalances resulting from an imbalance in the system. A VAV solution with Belimo ZoneEase™ actuators was implemented in each room for customized comfort regulation. This intervention led to significant temperature stabilization and improved energy efficiency, reducing energy consumption by 53%.

Citizens Plaza, Nashville (USA)
Savings of 23,000 USD per year
The 15-storey Citizens Plaza office building, which was built in Nashville in 1984, incurred high fee payments to the district heating supplier due to thermal inefficiency and overpumping. This changed when 15 Belimo Energy Valves™ were commissioned.
The retrofit project enabled Belimo Energy Valves to reduce the amount of cold water pumped by 49%. This corresponds to savings of around 23,000 USD per year.

Collège Laval (Canada)
Record air quality precisely in real time
Collège Laval, a private high school in the Canadian province of Québec, set out to improve energy efficiency, maintenance, thermal comfort and indoor air quality through a comprehensive HVAC modernisation and renovation project. For this purpose, 115 room sensors from Belimo were used.
With the help of the intelligent room sensors, the air quality in the school can now be precisely determined. Each sensor is easily readable, so data can be accessed via the Belimo Assistant App and smartphone in real time and without prior calibration. This allows settings, commissioning and troubleshooting to be carried out in a de-energised state.
