What is your area of expertise?

My own background is in marketing, strategy and business leadership, but the area I represent is vibro acoustics, specifically acoustics, vibration isolation and restraint systems for HVAC applications. What makes this field interesting is that these areas are all connected. We help reduce unwanted noise, control vibration and secure equipment so it remains safe and functional, even during extreme events. 

Why should customers care more about acoustics and vibration in buildings?

Because you usually only notice them when they are not handled well. If a room is too noisy, if air is blasting at you, or if vibration creates discomfort, it affects how people experience the building. Good acoustics support comfort, concentration, sleep quality and overall wellbeing. From an owner perspective, it also affects building quality and long-term value. 

What are the main customer benefits of addressing acoustics and vibration early in a project?

First, it is much more cost-effective to address acoustics and vibration during design than after installation. Retrofitting later can become extremely expensive. Second, early decisions can protect both comfort and safety. Third, it helps make sure the system performs as intended, without creating unnecessary energy penalties or operational problems. 

How does Swegon’s approach to acoustics and vibration compare to more typical HVAC solutions?

In North America, we are unique in being able to offer acoustics, vibration isolation and restraint systems together. Many others provide only one part of the picture. We can take a broader view and act as a single source of responsibility for all three. That matters because these issues are often linked in the real application. 

How does acoustics and vibration relate to sustainability and system efficiency?

Noise control is not only about attenuating sound. If you place a silencer or another acoustic measure in the wrong way, it can increase pressure drop and reduce system efficiency. Our role is to find solutions that manage noise with as little impact as possible on airflow and energy performance. That system perspective is a key part of our value. 

Why is it important to engage not only to consultants, but also to building owners?

Owners are often the ones who care most about long-term building value, occupant experience, resilience and sustainability. They may not buy the product directly, but they influence the priorities of the project. If they understand why these issues matter, it becomes easier to protect quality all the way through the process, rather than letting important considerations be value-engineered away. 

How do you see this area develop over the coming years?

I see strong potential in digitalisation, sensors and AI. Buildings could become better at detecting changes in noise, vibration or airflow before they become real problems. Over time, we may also see more adaptive acoustic solutions that respond to how a building is used, and more focus on materials and designs with lower embodied carbon. 

How does climate change affect the relevance of your work?

Unfortunately, more extreme weather events mean a greater need for restraint systems and resilient design. At the same time, the broader goal should be to reduce the environmental impact of buildings overall. So there is a balance: we need to help buildings become more robust, while also contributing to the transition towards more energy-efficient and sustainable building solutions. 

Any fun facts that capture who you are outside work?

I am a Lego nerd at heart. I use Lego in team energisers, I keep it both at home and in the office, and one of my favourite sets is the Avengers Tower. It is a fun way to bring creativity and energy into the team.
