I’ve been publishing a magazine on how to make buildings sustainable since 2003.

I’m terrible at social media - it doesn’t come naturally to me - but I have a few ideas that might help.

First, we need to clearly define what we do and don’t mean by sustainable. Confusion erodes confidence. 1)

Today I'm writing to my MP to support a ban on fossil fuel advertising which is being discussed in Parliament following a successful petition started by @chrisgpackham.bsky.social. This ban must include the sponsorship of educational materials and any #greenwashing in schools.

A starter pack for #InternationalWomensDay.

The construction industry has been disproportionately male, but that’s changing.

We’ve curated a starter pack of some of the amazing women leading the way on climate action in buildings.

Is a green home more than a house? What about outside? Ranking 13th, 36.6% of respondents to our #SMARTER4EU Green Homes Sentiments Survey said #biodiversity was essential. That seems low, given a manicured lawn is a desert for insects & animals. Have your say: www.surveymonkey.com/r/BYPQVJH

I’m not into football, but understand many are. So David has a great point here.
There are 3.5 billion football fans in the world. Famous footballers could be the trusted messengers we need to communicate important issues like human rights and climate. Too bad so many of them have been captured by monied interests using them for sportswashing.

I called this the most important article of the year (in 2021) It still is.
Mass timber has a place, and arguably it should only be for taller buildings, which are beyond the reach of regular timber frame, or particularly lean approaches like larsen truss or I-beams.

This article by Lenny Antonelli + @moreourselves.bsky.social explains why. 14)

Resolution for 2025: I will bug you harder about climate-ready low-tech deep renovations. Even if it hardly gets through because it seems most of you still believe new construction is possible in todays quantities.

MineCraft is very easy to get into for a very wide age range.
Unfortunately Mojang doesn't allow you to generate XP through providing the most low carbon dwelling possible 😔
I'm also not too sure what the carbon output is of an exploding Creeper. They're DEFINITELY not environmentally friendly.

Astonishing.

Gas Networks Ireland, the state-owned gas operator, takes out an ad that looks like a news article to advocate for building an LNG terminal.

‘A gas emergency would quickly turn into an electricity emergency. It is low-risk, but high-consequence’
With energy security a concern until Ireland has developed Indigenous renewables at scale, Bobby Gleeson, Gas Networks Ireland’s chief operations officer Ireland says that Ireland needs a gas storage ...

On the walk back from school today I was talking to my 11 year old son, Rex, about a #passivehouse version of the iconic poster for Ridley Scott’s Alien to promote the mag I publish, @phplus.bsky.social. Within an hour he emailed me this.

This thread 👇
really hope folks working in building science and public health start talking to each other a lot more because we're going to see massive issues with climate zone migration and wall assemblies designed for climate zones that no longer exist in that specific location.

If you want to known what climate leadership looks like, Paris and its region provide an excellent blueprint
“Grand Paris” is a staggeringly ambitious plan to knit together the city & its banlieus [suburbs] outside the ring road, a massive change.

Remember, 10 years ago...

We were told carrot not sticks, and to ensure the scale-up of economic alternatives to coal+gas power plants, petrol cars and home heating?

With all that ticked off, can we NOW talk about a global CO2 price?
