Customer Value

A Beacon of Sustainable Excellence

In 2022, Belimo unveiled its new 3’800 square meter Indian headquarters in Mumbai, built as a showcase for state-of-the-art HVAC solutions and sustainable design. Dubbed the CESIM® House, the building hosts logistics, customization, technical support, and an experience center, further strengthening the Company’s footprint on the subcontinent.

The Mumbai hub was originally conceptualized in 2016 as part of the Company’s 2030 accelerated growth strategy and represents a major commitment to the most rapidly expanding Indian market.

Belimo has long been a global leader in the heating, ventilation, and air-conditioning (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, warehouse, and customization space, the building also houses the Belimo customer experience center, created to actively support the customer journey toward creating healthier indoor comfort with less energy. The Mumbai hub is also a space where Original Equipment Manufacturers (OEMs) and academics can collaborate to design, build, and test the next generation of Belimo products.

Strong Focus on Sustainable Practices

The new headquarters was designed in collaboration with Envision Design Studio to exceed the Indian Green Building Council’s 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 was 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 aluminum 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. Moreover, the canteen features an open glass roof to save electricity from artificial light.

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 field devices to allow for precise monitoring and control of the temperature, air flow, humidity, and CO2 in each room – thus the name CESIM® House (acronym for Comfort, Energy Efficiency, Safety, Installation, and Maintenance, find out more on CESIM® here).

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” (for more information, read the story about the product launch of the room operating units). 

However, the advanced infrastructure does not end with the HVAC system, as louvers actuated by Belimo products 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.

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 30% of the office’s overall energy consumption.

Belimo has also been sure to take full advantage of Mumbai’s high levels of rainfall by installing downpipes on the roof, which collect and filter rainwater for use in toilets and watering landscaped areas. Flushed toilet water is also captured, filtered, and re-used, which, along with low-flow water fixtures fitted throughout, reduces demand on the municipal water supply.

Ready to Invite Our Customers

After completion, the state-of-the-art headquarters was successfully awarded platinum status, the Indian Green Building Council’s highest possible rating. As well as being environmentally friendly, CESIM® House was built with staff comfort and welfare in mind, featuring a spacious open-plan office, multiple breakout areas, a cafeteria, and a gym. It has also served as an excellent showcase of the advanced HVAC technologies of Belimo, sophisticated monitoring solutions, and automated control systems that together provide consistent indoor air quality without sacrificing energy efficiency.

When combined with intelligent, eco-friendly design and recycling of natural resources, the building has provided a glimpse into the future of environmentally conscious construction and the efficient use of workspaces. The innovative hub is on track to meet expectations, with initial measurements confirming the predicted 32% sitewide energy savings compared to a regular building1). Several energy meters precisely monitor the fluctuating energy demands across all four seasons and will hopefully confirm these results in 2023.

Gary Economides, Head of Asia Pacific at Belimo, commented: “We’re proud that this is one of the most eco-friendly and technologically advanced buildings in India. Being awarded the prestigious Indian Green Building Council’s platinum status – the goal laid out at the hub’s inception in 2016 – is a great achievement, and a testament to everyone involved.”

Not only will the new headquarters contribute to a reduction in our carbon footprint, but it will also enhance the comfort and wellbeing of our staff, which is of utmost importance. However, now the real work begins; we must educate our clients, contractors, and the general public on the benefits of the Company’s HVAC technologies and sustainable solutions that contribute toward a greener future.
