ABOUT
Synergy is the HVAC systems and energy management company for superyachts. Headed up by Patrick Voorn, an HVAC consultant started in 1988 in the maritime and offshore industry. Our team boasts more than 25 years technical knowledge.
At Synergy, we support you in every stage of your project. We fully appreciate that an HVAC system does not operate in isolation, but as the largest space and energy consuming system on board it has critical influence over almost every other onboard discipline. From the yacht’s profile and sophisticated interior to the amount of technical space required and the environmental footprint, the overall design and integration of an HVAC system is intrinsic to the smooth operation of a yacht.
We are experts in data monitoring, energy savings, air quality, system improvements, equipment specifications, comfort solutions, onboard surveys, and more. We pride ourselves on being a flexible company on whom you can rely on when making tough decisions during your project.
Client Experiences
“Over the years, Synergy has become our trusted partner for HVAC consultancy.
Patrick Voorn and his team consistently deliver outstanding service, supporting us from the initial phases of our new build projects all the way through to the final yacht hand-over to the client. Their deep expertise makes them highly recommended HVAC specialists.”
“The team at Synergy are a highly valued and trusted member of our specialist consultant group. They bring an excellent combination of extensive HVAC knowledge, practical experience, and strategic thinking, particularly when working within the complex and demanding environment of large shipyards. Their ability to provide informed, practical solutions and effectively navigate project challenges has consistently added significant value to the many projects we have worked on.
It is always a pleasure to collaborate with Patrick and his team, and we would happily use Synergy’s services again. Their input and expertise play an integral role in improving the overall performance, efficiency, and quality of the vessel, while making the whole process a lot more enjoyable along the way.”
“Synergy have been a trusted partner of ours for several years. Their technical advice is detailed and their solutions practical. They keep everything organised and easy to follow, and their communication is honest and open throughout. They’re a pleasure to work with, and the results speak for themselves – efficient, reliable, and delivered as promised.
Having a team member with such depth of technical experience and insight is valuable, and is to the benefit of any project.”
“I have had the pleasure of working with Patrick Voorn for the last 22 months on a project in Germany. Patrick was the Owner’s Team HVAC consultant. During this time we regularly sought Patrick’s advice and he attended the shipyard for progress meetings.
I can highly recommend Patrick and Synergy for their HVAC knowledge, professionalism and attitude.”
“Synergy was contracted as HVAC consultants for both the pre-contract phase and the construction / commissioning phase of Project Onward, a fully custom 100m new build motor yacht.
Patricks contributions to the design and execution of the HVAC system, the heat recovery system and the engine room ventilation system was invaluable. Patrick also was part of the drawings and document review process, shipyard and sub-contractor visits, harbour acceptance tests, and sea trials. He excelled in all these tasks.
I would be more than happy to work with Patrick again, and would highly recommend the services of Synergy.
“Synergy has proven to be an exceptionally reliable and valued partner within our specialist consultant network. Their team brings a strong depth of HVAC expertise, combined with extensive practical experience and a clear understanding of the technical and commercial challenges associated with major shipyard projects.
What particularly distinguishes Synergy is their ability to combine technical knowledge with a practical, solutions-focused approach. They are able to quickly understand complex project requirements, identify potential challenges, and provide effective recommendations that are both realistic and achievable. Their involvement has consistently contributed to the successful progress and delivery of the projects on which we have worked together.
Patrick and his team are professional, approachable, and highly committed to achieving the best possible outcome. Their willingness to collaborate closely with all parties and their ability to work effectively in demanding project environments make them an excellent addition to any project team.
We greatly value our relationship with Synergy and would have every confidence in recommending their services for future projects. Their expertise and contribution have made a meaningful difference, as well as to the overall success of the projects.”
“Synergy, and in particular Patrick Voorn, and my Team worked together over a 4+ year period on a sizeable and complex project. Synergy and the Owners Team were able to work extremely closely together with respect to all aspects of the HVAC systems and other associated thermal fluid and heat transfer systems onboard, including processes new to the Shipbuilder.
The collective input was extremely valuable in challenging the Shipbuilder and their chosen subcontractor on many aspects of the design and build process.
I personally found Patrick to be extremely approachable, accessible and knowledgable and this no doubt contributed to the successful delivery. Patrick continued to be available post build, which is outside of the remit of the project but was really appreciated.”

“Whilst working on a large new build, I met Zeb Robin and Norman Janneck of Bond Technology Management,” comments Patrick Voorn. “I immediately noticed their high level of quality output, and that the team was so well organised that they had full control over their scope of the project. The methodologies and processes that Bond operate by are, in almost every stage, closely matched to the HVAC process. Will Faimatea gave me the opportunity to demonstrate my skills and organisation, and here we are, a proud partner of the Bond Support & Services Group. We can’t wait to be involved in more projects together.”
