I really, really love Look Mum No Computer. I own quite a lot of his vinyl. I’m really disappointed he’s standing while the boycott is happening. www.bbc.co.uk/news/article...

So that was decent. Worth finding on catch up if you missed it. Props to Hannah from Progress in Practice for representing women working in retrofit - I promise despite the impression that might have been given, there are a few of us!

Watching "Guy Martin's House Without Bills" on #Channel4. Been looking forward to this!

While watching RTÉ's "Heat my Home", I was wishing that there was going to be a UK equivalent. Seems like Channel4 had read my mind. Not only with a great presenter like Guy Martin, but also @aecb.bsky.social Greater Manchester's local group ran by Progress in Practice Looking forward to watching.

I have both of Marion's "Residential Retrofit" books, so already knew this would be a good episode, even then it blew me away. Myth busting that low energy buildings require the occupant to "manage" their environment and the "rebound effect" is a non-issue. www.buzzsprout.com/2394957/epis...

imagine looking up at the vast and harrowing beauty of outer space and thinking not about how short and fleeting and precious our intertwined existence in this realm is but instead ‘wow this place needs some fuckin data centres’

I'm so excited for the Tour de France Femmes coming to Sheffield. I hope they close Snake Pass so we can cycle up there to watch them race. www.bbc.co.uk/news/article...

DIYers bringing #PassiveHouse to the masses? youtube.com/watch?v=v854... Absolutely loved this. So refreshing to hear people talk about this sorta stuff, in such depth, when they aren’t in the trade. Hopefully it might teach others to not to build crap leaky buildings with PIR. I can only hope.

@benadamsmith.bsky.social Catching up with HPH over Christmas; sad to hear The Hub is no more. I was just thinking about joining too, as after listening to so many eps, I recently figured self-build is for me in the future. My question is: could the resources& case studies be available as a one off?

It's been COLD. What flow temperatures are you folks using? (And for oil / gas / heat pump, or what? And to achieve what room temp?) Currently still working fine at 45C here in Belfast, gas combi, 19-20C target room temp.

people starting the new year with a shiny new substack when @ghost.org is literally right there smdh my head

I just posted some (a lot of?) pictures from my cycling trip through the length of Japan on my blog. sebastiandahl.com/blog/2025124... #japancyclingnavigator #bikepacking #cycletouring #japan

Got my work cut out for the weekend. Bedroom bay window is a stud wall filled with brick off cuts. To be insulated with 160mm of the finest German made woodfibre. New book for if I get bored too. More details in alt text. Current U-value is ~2.1W/(m²K), will be ~0.22W/(m²K) #retrofit #aecb

Good. George Clarke wants homeowners and businesses to shun ‘dishonest’ firms Arconic, Kingspan and Celotex www.theguardian.com/uk-news/2025...

There’s some very bad news hidden in the Ofgem price cap for January announced yesterday: the electricity to gas price ratio has jumped to 4.67, its highest level since before the energy crisis. This is a big barrier to households adopting heat pumps in Britain, and threatens our climate goals

Saw a video yesterday, someone talking about new Vaillant aroTHERM Plus #ashp : www.vaillant-group.com/news-stories... Distance req either side reduced: 100cm to 50cm Sound level (5kW): 51dB(A) to 44.3dB(A) Data: www.vaillant.de/heizung/prod... The video: www.youtube.com/watch?v=Czwk...

@archtesta.bsky.social Good to chat to you at the Homebuilding show! ubakus.de was the site I mentioned, and this was the data I got about phase shift: bsky.app/profile/snhd... PIR was even worse than my memory served at 6.5hr. Not a replacement for WUFI but feels useful for a layperson.

Wishing wood fibre insulation was as readily available in the UK as it was in France (this was at Brico Depot). This is something I should be able to buy from B&Q or Wickes not limited to specialist suppliers where postage is 3x the item price in some cases. #retrofit

Just starting your self build journey? I recommend listening to this podcast first. Andy Mitchell from 21 Degrees outlines the challenges of finding a healthy, comfortable and energy-efficient home. And he explains it all in simple language! www.houseplanninghelp.com/andymitchell #SelfBuild

A good day to re-read this post: charity.wtf/2019/05/01/f...

#passivehouse peeps, is the ~new "easyPH" compatible with #PHPP "Variants" worksheet? I see it's there but hidden, and I didn't see a mention in the manual. Alternatively, is modeling in easyPH then exporting into the full variants sheet an option. NB: not being used for certification just fiddling

PassiveHouse peeps, is the ~new "easyPH" comptatible with #PHPP "Variants" worksheet? I see it's there but hidden, and I didn't see a mention in the manual.

Spent an evening in Walkley at an SY Ecofit event. Chatting all things retrofit, insulation, moisture in buildings and also enjoyed this lovely curry. #sheffield #retrofit

She walked 6.5km for this photo but we forgot the biscuits.

Flat white, cheese toastie and the latest copy of Passive House Plus magazine. Solid bank holiday Monday activities.

Read this book at the weekend, would highly recommend to any homeowner, even if you aren’t planning a renovation. I especially liked this little illustration feat ASHP and solar panels. #retrofit #renovation #mvhr #ashp #passivehouse

If you're curious about comfortable and well performing housing, I can't recommend this episode enough! An incredibly accessible explanation for such a deep topic. Touches on: why housing is so poor; what the future could be and areas to focus on when improving your current home.

Idea: Feature Flags but so users can turn off all the nonsense they don’t care about in your app.

Looking for examples of people who've done an "AECB Step by Step Retrofit" but struggling to find anything. I know it's somewhat of a new standard and that's likely why. Ideally blog posts or forum posts from homeowners but curious to read anything. cc @aecb.bsky.social and #passivehouse

Why do engineers talk like they're a fighter pilot? All 'merge conflict' this and 'deploy' that. 'Oooh I need to bisect the rangediff'. What are you TAlKING about? Grow up

We are finally ready to announce that EMF 2026 will happen on July 16-19, 2026, at Eastnor Castle Deer Park, Herefordshire. Expect more updates soon as we start spinning up the organisation again.

This is some very expensive parcel tape…

@benadamsmith.bsky.social Hey, your website looks like it's having some issues at the minute

Curious how much air tightness in housing helps with this current hot weather? Its help is reasonably common knowledge for cold and blustery weather in winter. (Haven’t searched about it yet but the q just popped into my head, basically thinking out loud)

TIL my house has a built in summer storage heater. Bay window is tiled and filled with single skin of brick. 33c at 11pm at night! At the time of reading room temp was 26c and outside 21c.

This is the closest I've felt to being in one of those museum exhibits from the comfort of my own desk

@shed.gay I assume this is something you may have knowledge of. I think I want a portable heating/cooling/dehumidifying thing. I see that they exist but does a _good_ one exist?

Bristol has soooo many bikes! (I brought my own too)

We are gearing up for what could be the hottest June day ever in the UK. So how can external shading really help on a day like today? houseplanninghelp.com/paulmorris #Passivhaus #PassiveHouse #Overheating #ExternalShading

Yesterday I spent the day with @be-stbuild.bsky.social & @coaction.bsky.social putting Passive House theory into practice. In the morning sequencing insulation and membranes into a retrofit rig. So helpful even as a homeowner and not being in the trade.

PassivHaus Planning Training today!

@dataknotsdesks.bsky.social This was that site I had mentioned: www.ubakus.de/en/u-wert-re... And then with my plans: hachyderm.io/@seanhood/11...

It’s #O11yDayLondon time!

AWS costs for "Managed Prometheus" reads like that Dril candles budget meme

This is my favorite passive house and if (when?) I was to build a house I'd also likely chose the PH15 system.
