Damien Queally of Plan International on Empowering Youth for Sustainable Change
In this Youth Month special, Plan International’s Chief Programme Officer Damien Queally joins youth host Ciara O’Brien to unpack what truly locally led, gender-responsive programming looks like—especially where climate shocks meet the built environment. “If you’re not bringing young voices in, you’re making decisions with your eyes closed.” From safe, climate-resilient schools and health centres to inclusive streets, water systems, and shelters that protect girls, Damien makes the case for community-owned solutions that put young people—particularly girls—at the centre of how we design, govern, and maintain the places we live. Tune into Plan International Chief Programmes Officer, Damien Queally, and Plan International Global Young Influencer, Ciara O’Brien, as they discuss their work with Plan International, a global organisation focused on improving the lives of girls and women in the developing world in a sustainable and equitable way. Their conversation focuses around their approach to this work, youth leadership within the organisation, and current affairs.   Damien Queally Plan International “We shouldn’t be in a community for 30 or 40 years—our job is to help build self-reliance and shift ownership locally.” As Plan International focuses on International Day of the Girl 2025, we dive into the campaign in more detail. The launch of the 2025 State of the World Girls Report has caused a stir in the international community. Damien and Ciara explore the specifics of the research and the gl...

Ireland’s Retrofit Race — with Dr. Ciarán Byrne (SEAI)
How Ireland is making homes warmer, cheaper to run, and lower-carbon—at real scale—and what you should actually do first. Ireland’s Retrofit Race Ireland set out to decarbonise its housing by upgrading existing homes—insulation first, fossil heating out, heat pumps and other renewables in. Dr. Ciarán Byrne from the Sustainable Energy Authority of Ireland explains what “retrofit” really means, where the numbers stand, what’s working, and how to start your own upgrade without getting overwhelmed. Ireland’s Retrofit Race with Dr. Ciarán Byrne “Anything you do in this space is no-regrets work.” Dr. Ciarán Byrne C Dir Why listen to Ireland’s Retrofit Race Plain-English retrofit 101: What counts, what doesn’t, and why external wall insulation can make a whole street look brand new. Real progress, real targets: Thousands of upgrades each year, with a growing share of homes reaching a strong BER rating. Money + logistics, demystified: Grants that can be netted off your bill, low-cost green loans, and why using registered contractors matters. Old buildings, smart fixes: How “breathable” materials and traditional-home know-how avoid moisture traps in heritage fabric. Myths busted: You usually don’t need to move out for a deep retrofit; confusion often comes from bundling retrofits with kitchen or bathroom refits.

David Picton on Safety, Sustainability & the Rise of the Lone Worker
Safety isn’t a box-tick—it’s a living culture. David Picton shares hard-won lessons from military logistics to boardrooms and major infrastructure projects. We dig into why lone workers are growing fast, how extreme weather is reshaping site risks, and how connecting culture with smart tech turns “compliance” into prevention. You’ll hear real examples—from JLL to Costain—and a pragmatic playbook any firm can use. “Safety works when everyone has permission to call it out—from apprentices to execs.” David Picton What we cover with David Picton 1.  Lone workers: why they’re on the rise, the unique risks they face, and how to protect them. 2. Climate disruption on site: heat, storms, floods—and the simple factors (shade, hydration, acclimatisation, permission to speak up) that change outcomes. 3. Culture that speaks up: the “permission” moment that proves safety works when everyone can challenge—even a junior apprentice. 4. Data into decisions: how visibility lifts reporting and drives action. 5. SME playbook: low-cost, high-impact moves for smaller firms to handle extreme weather and continuity. Courtesy of Ecoonline “Technology plus culture is the shift—from basic compliance to predicting issues before they happen.” David Picton Practical takeaways for daily use Start with risk assessments on your highest-exposure tasks and locations. Keep them live as conditions change. Plan for weather: set clear comms trees, cross-training, and alternative task lists for

Good News: A New Way To Look At Sustainability & Pocket Forests & Retrofitting in Ireland
In this uplifting edition of the Constructive Voices Good News podcast in less than six minutes, we bring you a short, sharp burst of positive stories from the built environment — with a dash of conservation inspiration. A New Way To Look at Sustainability: Neurosustainability We open with a fascinating concept that’s as much about protecting our minds as it is about protecting the planet — neurosustainability. Host Jackie De Burca speaks with Mohamed Hesham Khalil, whose pioneering research at the University of Cambridge explores how the built environment affects our brain health, mental wellbeing, and cognitive performance. “That shift… from experiencing the built environment in a specific way and then going back was an alert to start seeing this relationship between the built environment and the human brain.” — Mohamed Hesham Khalil Discover how architecture, neuroscience, and nature intersect — and why this matters more than ever post-lockdown. Greening Ireland: Pocket Forests Next, volunteer reporter Sarah Austin speaks with Catherine Cleary, co-founder of Pocket Forests, about transforming small urban spaces into thriving native woodlands. With over 125 sites planted — from car-parking-space-sized micro-forests to half–tennis-court plots — these dense plantings are changing soil health, biodiversity, and community connections. “We’re planting much younger trees… much more closely together… the result is that they create this microclimate very quickly.” — Catherine Cleary For the full deep dive, check out our special episode Greening Ireland from Pocket Forests to Native Woodlands on our website.

The Energy Performance of Buildings Directive (EPBD): A Game-Changer for European Building Sustainability With Stephen Barrett of the IGBC
Is Europe on the cusp of a green building revolution? Find out in this podcast episode. In this episode of Constructive Voices, we’re joined by Stephen Barrett, the driving force behind Ireland’s transition to whole-life carbon assessment in construction. (Bookmark this page for the release date of 29th July) As Programme Manager at the Irish Green Building Council (IGBC), Stephen is at the heart of implementing the updated Energy Performance of Buildings Directive (EPBD)—a policy shift that’s set to transform how we design, construct, and assess buildings across Europe. Whether you’re a building designer, material supplier, or policy watcher, this is the insight you need to prepare for what’s coming. "Don’t worry about the result—just begin assessing. It’s the act of questioning your design that starts to change behaviour." — Stephen Barrett, IGBC Who Should Listen? Architects, engineers & building designers Construction managers & BIM specialists Sustainability officers & ESG consultants Policy makers & local authorities Students and educators in built environment studies Key Topics Covered What the updated EPBD really means—and why it’s a "starting gun" for industry change. Why lifecycle carbon is overtaking energy as the key metric in building performance. The vital role of BIM (Building Information Modelling) in meeting new EU carbon targets. Open source vs proprietary BIM platforms: How to start now, without breaking the bank. Lessons from the Nordics, and how Ireland’s ahead of the curve with its prototype methodology. What the construction industry must do before 2030 to stay compliant—and competitive. Why your old tools won’t cut it anymore—and how new platforms like One Click LCA are changing the game. Simple advice for professionals: Start assessing now—don’t fear the results. "If we design with carbon in mind from the beginning, we won’t just build better—we’ll change the entire supply chain behind construction." — Stephen Barrett, IGBC About Stephen Barrett Stephen joined the Irish Green Building Council (IGBC) in 2020 and is currently Programme Manager for Whole Life Carbon initiatives. He has contributed to several key European and national projects, including Level(s) – the EU framework for measuring the environmental performance of buildings – and the #BuildingLife campaign, aimed at aligning public policy and industry practices with Whole Life Carbon (WLC) goals.

Zurich A Living Lab for Sustainable Cities With Anna Haas
In this insightful episode of Constructive Voices, Jackie De Burca sits down with Anna Haas from Neustark to explore the city she calls home—Zurich. Known for its efficient public transport, green infrastructure, and direct democracy, Zurich has long been a sustainability frontrunner. But how is it maintaining its reputation amid global competition? Anna unpacks the urban planning, mobility strategies, carbon removal innovations, and deep-rooted community involvement that define Zurich’s approach to sustainable development.
