Passive Dynamics has announced a series of senior leadership promotions as we enter our next phase of growth across Ireland and the UK.
John Treanor has been appointed Director, with David Devlin and Liam Guinan promoted to Associate Directors.
The appointments reflect our continued expansion within the construction sector and our focus on delivering measurable, performance-driven sustainability outcomes across the built environment.
Passive Dynamics was founded on both architectural and engineering expertise. We work with developers, investors and design teams to improve the energy and carbon performance of buildings.
Our services span the full building lifecycle, from sustainability strategy development at concept design stage, through regulatory compliance and green building certification, to the optimisation of in-use building performance across commercial, residential and logistics developments.
The strengthened leadership team supports the company’s continued growth while maintaining technical excellence, rigorous quality assurance and a clear focus on measurable, verifiable outcomes.
“These promotions mark an important milestone for the business.
They strengthen our leadership capacity while ensuring we continue to deliver high-quality, performance-focused outcomes for our clients as we grow.”
said co-founder Ciarán McCabe.
