    Lazy thinking and unsustainable myths: how expensive is low-carbon construction? A conversation with the authors of 'Building for 2050: low cost, low carbon homes' Alison Crompton (AECOM) and Tom Dollard (Pollard Thomas Edwards)

    Lazy thinking and unsustainable myths: how expensive is low-carbon construction? A conversation with the authors of 'Building for 2050: low cost, low carbon homes' Alison Crompton (AECOM) and Tom Dollard (Pollard Thomas Edwards)

    Insidious misconceptions, false myths, and the lazy thinking pervades the green building sector, we're not happy about it, and nor are the authors of 'Building for 2050 Low cost, low carbon homes'.

    This is a recently published BEIS research paper 
about how low carbon construction is held back by a false understanding of what it costs, how hard it is, and what its users actually think about living with it.

    More bridges than the River Clyde: unpicking the quality of a retrofit and RIP Paul Doran

    More bridges than the River Clyde: unpicking the quality of a retrofit and RIP Paul Doran

    Today we saw a LinkedIn post today that Dan wanted Jeff to explain to him. At the centre of it was an image of a retrofit job that looked dubious. We also took a little time to acknowledge the tragic death of Paul Doran, one of the best and most forward-thinking builders Jeff has ever encountered.

    Hybrid heating: a place for fossil fuels alongside renewables? (Stephen Kelly, OYA Energy)

    Hybrid heating: a place for fossil fuels alongside renewables? (Stephen Kelly, OYA Energy)

    We had a contentious discussion last Friday about hybrid heating systems, a transition technology that could play a role in the decarbonisation of home heating.

    Stephen Kelly of OYA Energy joined us for a grilling from a very skeptical Jeff, to make his case for the use of heat pumps alongside legacy gas boilers. It's important to note that this is intended as a transition technology, not an ultimate end.

    'Incompetence still reigns supreme' in energy ratings: DPE certification, EPCs, BERs, and a little bit of ESG

    'Incompetence still reigns supreme' in energy ratings: DPE certification, EPCs, BERs, and a little bit of ESG

    It's all about how 'incompetence still reigns supreme' as we discuss DPE certification (the French EPC) and some appalling advice that was sourced by the French version of Which? magazine, Que Choisir, in an article about shopping around for your DPE. We also talked about EPCs, BERs, and a little bit about ESG (the post-punk band as well as the 'ethical' value metrics).

    New year, old us: looking back on 20 years in green building (Passive House Plus, Construct Ireland, and Everything is User Experience)

    We'd arranged to have a post-Christmas catch-up about a few things and Alex suggested people might be interested in hearing about the genesis of Passive House Plus and its progenitor, Construct Ireland magazine, and the changes we've seen throughout the green building industry across those 20 years.

    Talking turkey: the perils of life in a passive house, with Ross Cremin (Cremin Surveying)

    Talking turkey: the perils of life in a passive house, with Ross Cremin (Cremin Surveying)

    On the night before, the night before, Christmas, we spent the morning with Ross Cremin a QS with a lot of experience in passive house building [I know what I wrote – Dan].

    Broadly, we talked about what it's like to live in a Passivhaus building, eating seagulls in celebration of Christ, heating homes, and all the other usual things.
