  • Embodied carbon assessment with Adrian Campbell
    Mar 10 2025

    In today’s podcast we take a deep dive into embodied carbon and try to get a better understanding of why infrastructure professionals need to make its assessment more than just a nice add on but a fundamental part of the design process.

    The construction and infrastructure sectors are undergoing a major transformation as the industry seeks to reduce its carbon footprint and meet global net-zero targets. While operational carbon—emissions from heating, cooling, and electricity use—has traditionally been the focus of sustainability efforts, embodied carbon - emissions that are locked in at the point of construction and cannot be reduced over time - is now taking centre stage.

    To discuss this issue, my guest today is Adrian Campbell, founder of the Change Building consultancy and someone that I like to describe as an industry sustainability guru and my go-to expert when it comes to reducing carbon across the infrastructure lifecycle.

    Full disclosure; I have known Adrian since we studied Civil Engineering together at the University of Southampton back in the 1980s. Well, he did the studying as I remember!

    Adrian has made a return to the University of Southampton as a tutor and lecturer and as Royal Academy of Engineering Visiting Professor in Sustainable Development and Climate Impact He has just produced a new guide to help students get to grips with assessing embodied carbon - a rapidly developing area of professional competence which should provide the skills and judgment to help improve designs and help move us towards the goal of net zero carbon.

    For students entering the fields of architecture, engineering, and construction, embracing embodied carbon assessment is no longer optional—it is a vital skill for shaping a sustainable built environment.

    As Adrian puts it, having an awareness of the reasons for its adoption (the ‘why’) and some experience of assessment (the ‘how’) is now expected as part of the role of the engineer.

    However, this presents challenges: data inconsistencies, limited industry knowledge, and balancing carbon reductions with performance and cost make it a complex area to navigate. So let’s find out why students should engage with embodied carbon thinking early in their careers.

  • Retrofitting: the future of housing with Anna Moore
    Mar 3 2025

    Today we head back to the vitally important issue of housing and attempt to understand the UK’s complex, and some might say, largely dysfunctional housing retrofit market.

    It is a market that is rapidly evolving, driven by ambitious government policies, rising energy costs, and increasing public demand for sustainable, lower cost living. But with a housing stock that is among the oldest in Europe, the UK faces significant headwinds to meet this challenge.

    But my guest today has embraced this challenge whole heartedly and two years ago quit a successful career with global consultancy McKinsey and Co to strike out on her own. Anna Moore formed Hestia, now rebranded as Domna, as a brand-new business to transform our approach to domestic retrofit and, at the same time, lever in large amounts of much needed private sector investment.

    It's a tough market. Because, as Anna knows I am sure, while the government’s commitment to building 1.5 million new homes continues to grab the headlines as the key to driving up living standards and revitalising communities, the need to retrofit our huge existing stock has been left something of an overlooked, Cinderella sector.

    Yes, recent initiatives, such as the Future Homes Standard and the Social Housing Decarbonisation Fund – now renamed the Warm Homes Grant, have boosted the focus on retrofitting to enhance energy efficiency, lower emissions, and reduce fuel poverty. And the market is seeing growing interest in innovations like heat pumps, solar panels, insulation upgrades, and smart energy systems.

    However, the sector faces hurdles, including supply chain constraints, skilled labour shortages, and the challenge of balancing affordability with high-quality retrofits.

    That said Anna has just secured a £70M cash injection into the business which she hopes will open up a £500bn opportunity that will help the business to play a critical role in creating healthier, more efficient homes for residents.

    So, let’s find out how.

  • The affordable housing crisis with Anette Simpson
    Feb 24 2025

    In today’s episode we dive into the UK’s deepening housing crisis– specifically looking at affordable housing where demand is still far outstripping supply.

    Despite ambitious government targets to deliver 1.5 million new homes over the next five years, the reality is that we are still only seeing 50,000 to 60,000 affordable homes being built each year - far short of the estimated 145,000 required.

    The shortfall leaves over 1.3 million households on waiting lists, while rising costs, planning delays, and economic uncertainty continue to challenge the sector.

    My guest today is Anette Simpson the director of development and partnerships at Legal & General Affordable Homes where she is responsible for overseeing the delivery of some 3,000 affordable homes annually.

    Legal & General Affordable Homes (LGAH) was founded in 2018 to bring institutional investment into affordable housing, leveraging private sector funding to help bridge the gap.

    The business has ambition and Anette’s target is to have more than 10,000 homes under management this year. It aims to prove that, alongside the tradition public sector social housing providers, for-profit providers can play a crucial role in tackling the crisis.

    As such their approach combines long-term investment with cutting-edge technology, ensuring both sustainability and high-quality service for residents.

    However, the sector still faces significant barriers. Planning inefficiencies, limited government funding, and the financial pressures on housing associations are slowing progress. Meanwhile, challenges such as building safety upgrades, decarbonisation targets, and interest rate hikes are forcing traditional providers to scale back development.

    And to attract further private investment, the industry needs greater stability, a more efficient planning system, and well-resourced local authority partners.

    So let’s hear more as we explore LGAH’s role in shaping the future of affordable housing in the UK.
