Mosart has helped shape the industry from the ground up with over 30 years of expertise in sustainable design and consulting. We designed the first certified Passivhaus in the English-speaking world, and today we support projects of all scales through integrated architecture, technical consultancy and internationally recognised training.

Our consulting team includes six in-house Passivhaus certifiers, the largest in Ireland, and offers a comprehensive suite of services including thermal bridge modelling, energy analysis and feasibility studies. Using methodologies developed in-house, we’ve improved both the speed and accuracy of early-stage performance assessments, helping clients make informed design decisions from the outset.

As educators, we’ve trained over 2,500 professionals through our Certified Passivhaus Designer courses, building the practical knowledge and confidence needed to deliver truly high-performance buildings.

At Mosart, we don’t just teach Passivhaus. We live it. And we’re here to support the next generation of designers, consultants and decision-makers shaping a low-carbon future.
