Success Stories List
Embarcadero Center, San Francisco (USA)
At San Francisco’s iconic Four Embarcadero Center, an aging chilled water system with two-way, pressure-dependent globe valves and pneumatic actuators was struggling with low 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)
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.Watch our video to learn how Allseas is using innovative Belimo valve technology to maximise energy efficiency at sea and significantly reduce operating costs.

Paramount Group, New York (USA)
In response to a regulatory mandate in New York City focused on improving energy efficiency and reducing carbon emissions for large buildings starting in 2024, a major property management company upgraded key buildings with the Belimo Energy Valve™, a pioneering, IoT-enabled device designed to optimize energy use and maintain Delta T in HVAC systems.
The upgrade dramatically cut energy use and costs – saving over $1 million in electricity in 2023 alone. The effort also earned Paramount $2.1 million in utility incentives, aligned the buildings with 2030 carbon reduction goals, and secured top sustainability certifications. This marks a significant stride towards the 2050 carbon neutrality target, demonstrating a strong commitment to sustainability and efficiency. Watch the video to find out more about the CO2 reductions and cost savings.

Belimo Office, Großröhrsdorf (Germany)
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 19,000 m2. Before our own RetroFIT+ specialists intervened, the site consumed 750,000 kWh of gas annually.
Through a series of targeted adjustments and modernization 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 amount 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.

Hotel Admiral Bergen (Norway)
Efficiency Made Easy: A Belimo Energy Valve™ Story
Retrofitting of the historic Hotel Admiral Bergen (Norway) was already in full swing when Geir Hovden of DNB Commercial Real Estate learned about the Belimo Energy Valve™ through a particular episode of the Practical PropTech podcast. That episode examined closely how cutting-edge technology, such as the Belimo Energy Valve™, is transforming the way we manage building operations and saves energy. Although already midway through the project, it was immediately decided to pivot and equip the hotel's hydronic system with Energy Valves. Their decision yielded impressive results, including enhanced operational efficiency, significant cost savings, and a substantial contribution to their sustainability goals.
Watch the video to discover how our innovation makes installations easier and provides valuable insights for better, smarter building management.

Citizens Plaza, Nashville (USA)
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.

Wastewater Treatment Plant, Pontives (Italy)
80% methane gas savings
Ideally, a wastewater treatment facility should be powered by the biogas generated from its own operations. Prior to the optimization of the HVAC system at the wastewater treatment plant in Pontives, this wasn't the case. The facility had to purchase approximately 125,000 NM3/year of methane gas from the external grid.
With the installation of the Belimo Energy Valve™ and upgrades to the facility, the annual purchase of methane gas has fallen to around 25,000 Nm3/year, resulting in savings of 80%.

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

Opella Healthcare, Origgio (Italy)
50% reduction in energy consumption
With the goal of expanding production capacity while minimizing environmental impact, pharmaceutical company Opella Healthcare embarked on a project to modernize its manufacturing facility and HVAC system.
The retrofit project involved 6 Air Handling Units (AHUs) and the installation of 28 Belimo Energy Valve. These valves converted circuits from constant to variable flow, which ensures optimal dynamic balancing according to the needs of the AHUs. As a result, the project achieved a 50% reduction in energy consumption.

What you should start with optimizing HVAC
Three steps, three paybacks; optimize first to unlock later savings
- Fast ROI, immediate impact, low downtime: Short, OPEX-sized scopes.
- Right-sizing dividend: lowerpeak load after optimization (~5-15%) lets you select smaller, cheaper plant later.
- Comfort preserved: sequencing and hydronic fixes reduce complaints, overrides, and noise.
- Decision clarity: Ranked measures with costs, savings ranges, and operational risk.

EPBD is tightening. Controls and data proof move from "nice to have" to required. Act now with low-disruption control upgrades and commissioning that stands up in filings.
01
Authorities are enforcing functional checks and smart control capability, and missing proof triggers remediation work.
02
Incentive funds deplete mid-cycle, and early claims improve payback and IRR.
03
Performance classes influence financing and asset value, and low classes depress exit outcomes.
04
Energy prices remain volatile, and every heating or cooling session without control burns cash. Energy prices remain volatile, and every heating or cooling session without control burns cash.
