📖 By far the best book I have read this year: “An immense World” by @edyong209. Such an eye opener on how other species perceive the world, and a call to humility.
The section on “sensory pollution” is a must read. 1/3

Energy transition critics often point to primary energy use to demonstrate that it's going to be impossible.
But 72% of the global energy input is currently lost after conversion.
The problem we're trying to solve here is a lot smaller than primary energy use might suggest.🧵

No heating on for 24h and a chunk of heat put into the hot 🚿 (our HW heat pump takes heat from inside) but the 🏠 is still nearly 20°C. Still surprises me after 10months in the house. #Passivhaus.
*electricians were in doing some snagging and I forgot to turn heating back on.

1/ Ugghhh. Here we go again. Bad journalism. Unless you live in a tiny & completely sealed container, house plants will not do what is purported in this article.

Good read about the groundbreaking green building in temple bar - 30 years old @IrishTimes @50Pa

Saw a critique of #Passivhaus recently that claimed MVHR generally only recovered a few degrees of heat. The reality, for quality units and installs, is much better than this. Today, typical winter weather, 12° difference between outdoor & supply temp.

Thoughts in @phplusmag edition 46 on the Govt. shared equity scheme- do your sums as it could end up being very expensive.. @50Pa

Wood, straw, hemp, clay, reused components and improved, repurposed existing buildings are to the #buildingtransition what wind, sun and efficiency are to the #energytransition. Do you agree?

This isn't an accident. This is why these very expensive interconnectors are built. They destroy high cost fossil power demand.

Ireland’s electricity CO2 emissions have fallen sharply this year. Our oil use is down 80%, coal down 50% and gas is down over 4%. Renewables are up 5%. It’s been said this is all down to imports, and even said that it is down to exporting emissions. its not that simple..🧵

“The default assumption that #climateaction is necessarily hard, expensive, and is going to make our lives worse, must be challenged. We need to get better at telling positive stories about climate action”. @50Pa ted.com/talks/jeff_colley_vi… @phplusmag

NEW RESEARCH: My new meta-review of 54 independent studies suggests no major role of hydrogen for heating.
Why?
✅ hydrogen is expensive
✅ hydrogen is inefficient
✅ there are better alternatives

1/ 🏴 Oh Scotland, we love you!
You've only gone and introduced #EmbodiedCarbon targets and reporting for new AND existing public buildings, PLUS an EUI target with mandatory annual reporting. Bravo 👏 tinyurl.com/3yr8r3fu

Was delighted to meet @50Pa and colleagues to discuss the findings of the @iiea’s paper on the benefits of energy efficiency in buildings.

New episode of Zero Ambitions Podcast is up: The benefits of energy efficient building are much more than energy efficiency, with Marion Jammet (Irish Green Building Council). Hope you enjoy share.transistor.fm/s/2fa871…

En route to Brussels for negotiations on the Green Buildings Law this Thursday. All going well, we'll deliver lower bills and less emissions. #EPBD
