Belimo’s lighthouse project
Belimo unveiled its new 3,800 square meter Indian headquarters, built as a showcase for state-of-the-art HVAC solutions and sustainable design. The Mumbai hub was originally conceptualized in 2016 as part of the company’s 2030 accelerated growth strategy. Belimo has long been a global leader in the HVAC technology sector and, given India’s recent carbon neutrality pledge, this was an exciting opportunity to design a structure from the ground up with the environment in mind. In addition to office and factory space, the building also houses the Belimo customer experience center, created to actively support the customer journey towards creating healthier indoor comfort with less energy. It is also a space where OEMs and academics can collaborate to design, build and test the next generation of Belimo products.

Strong focus on sustainable practices
The new HQ was designed in collaboration with Envision Design Studio to comply with the Indian Green Building Council’s (IGBC) Green Factory Buildings guidelines. Before a single brick was laid, the impact of construction on the local environment was a major factor, particularly the issue of soil erosion. Usha Narrasimham, Envision architect, explained: “Generally, excavation involves the removal and disposal of topsoil, which is rich in precious organic matter and plant nutrients. We prevented this by pumping the removed topsoil – suspended in water due to the high groundwater table – into a sedimentation chamber, where the water was drained, and the remaining soil used in landscaped areas located around the site.” The entire construction process continued to implement sustainable practices wherever possible. Eco-friendly building supplies – such as low VOC breeze blocks – and items containing recycled content were prioritized. As an example, the exterior tile cladding is made of an aluminium composite material with 80% recycled content. Additionally, all waste was either recycled or sold to recycling companies, ensuring nothing ended up in landfill.
Minimizing HVAC energy requirements
The external envelope of the building was given particular deliberation, with low U-value, reflective glazing installed to insulate the office from the Mumbai heat, which can reach up to 40 degrees Celsius. In fact, the exterior is clad with white tiles to reflect sunlight and keep down the internal temperature, minimizing HVAC energy requirements.
The interior also benefits from intelligent material choices, with pale office flooring scattering light from the large feature skylights, providing 90 % of the office’s illumination, and minimizing the artificial light required during working hours.
Precise linear motion with linear actuators
Precise monitoring and control
Due to high temperatures and humidity it was essential to incorporate pioneering ventilation and air conditioning solutions. To this end, a high-tech HVAC system was installed, and equipped with devices to allow for precise monitoring and control over the temperature, air flow, humidity and CO2 in each room – thus the name CESIM® House.
The louvers are controlled by linear actuators that are automatically operated based on lux levels and outside temperature measured by the rooftop weather station.
Belimo linear damper actuators are available with stroke lengths of 4, 8 or 12 inches and on/off, floating point or modulating control. The comprehensive range of 34 lbf [150 N force] to 101 lbf [450 N force] are ideal for a wide range of applications such as louvers, diffusers, greenhouse windows and anywhere linear motion is required.
Ketan Sheth, Product Manager at Belimo, said: “You can't control what you can't measure, and our network of embedded sensors, complete with intelligent control systems, allows for real-time monitoring and adjustment of the parameters needed to deliver consistent indoor air quality.” However, the advanced infrastructure does not end with the HVAC system, as actuated louvers are fitted over the exterior windows, and automatically adjust their angle to maximize shade at all times of the day. Additionally, adaptive illumination systems can sense when a room is unoccupied and automatically switch off the lights.
Belimo Energy Valve™ for energy-efficient operation and balancing
The Belimo Energy Valve™ provides pressure-independent flow control and transparent monitoring of the chilled water system. This ensures that it is not operated with too low a temperature spread (delta T). By measuring, calculating, and visualizing important system data and with the performance reports, energy-efficient system operation and balancing is guaranteed for the entire service life.
Sensors for reliable and accurate measurement and monitoring
The building has smart AHUs that are equipped with Belimo's complete range of sensors to measure temperature, humidity, CO2, pressure, and flow. Belimo's sensors provide a precision-controlled, comfortable room environment that is essential for the well-being and productivity of people.

Use of solar energy and rainwater
The Company’s eco-friendly ethos is not limited to construction methods, building materials and intelligent systems, and includes the continued use – and re-use wherever possible – of natural resources. For example, solar panels positioned on the roof harness the sun’s energy and deliver unused energy back to the grid, providing 20% of the office’s overall energy consumption.
