About this episode
The episode features Tomas O'Leary discussing sustainable design and scaling solutions for a better future.
Today we are recording live from BE-ST Fest where we are focusing on ‘Scaling Solutions’. This means we’re exploring how we chart a viable path to a sustainable future. Over the past few years, we’ve seen inspiring projects that prove change is possible, from new materials, products, and systems, to radical rethinking around how we deliver the kind of better new and existing, housing and infrastructure we need. Now the question is: how do we take what works and scale it at pace, so it has a real, lasting positive impact on our places, our people, and our planet? In our first episode of the series, we welcome Tomas O'Leary , Managing Director of Mosart . With over 30 years’ experience, Tomas has been a pioneer in zero-carbon, energy-efficient design—blending Passivhaus expertise, innovation, and collaboration to create sustainable, high-comfort buildings that contribute to a better, more inclusive future.
