#RetroFit

2025-12-10

Omer a eu la gentillesse de me permettre de parler de #retrofit au musée dans la dernière édition de @muzeodrome :

"Penses-tu qu’il soit possible d’utiliser des appareils “retrofittés” comme dispositifs de médiation dans les musées ?

Oui ! Je pense que la matérialité de leurs interfaces s’y prêterait particulièrement. Le plaisir d’appuyer sur un gros bouton ou de tourner un potentiomètre est universel. Je pense surtout qu’ils y seraient plus à leur place que les bornes à écran tactile qui fleurissent partout. La promesse de l’écran tactile c’est l’interactivité, mais on sous-estime l’expertise et le budget nécessaires pour développer de bonnes interfaces numériques. Pire, alors que la scénographie des musées apporte une grande attention à l’éclairage, la luminosité d’un écran attire le regard, au lieu de le guider vers ce qui est exposé."

(avec aussi une chouette notule à propos des 3DS du Louvre)

I keep posting my #retrofit stuff to bsky as that seems to be where the other #passivehouse people are but ought to post them here also:

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)

From the thermal image, can see how bad the problem is. The detail is showing a horizontal midsection slice, it's also more complex as this is a curved wall. I hope to also insulate the part of the wall between the floor joists too.

#retrofit #aecb #woodfibre #ubauks

Pack of STEICOflex 036 wood fibre insulation batts, with a book called "What the Builder Won't Tell You" and behind some STEICOinternal rigid woodfibre insulation.Build up detail made using ubakus.de. The baywindow wall is basically a vertical roof so I'm going with a similar method of how you insulate a roof. All mebranes will be taped with pro clima tescon vana air tight tape

1. Tiles
2. Battens
3. pro clima Solitex Plus (vapour open membrane, allows the build up to "breath") this will actually be installed from the inside zig zagged around the studs.
4. STEICOflex 036 between studs
5. STEICOinternal rigid boards over the top
6. pro clima Intello Plus (air tight membrane, which varies it's vapor diffusion)
7. Plasterboard 

Total build up reaches a U-value of 0.22 and a phase shift of 11 hours.Thermal image of my bay window wall. Cavity wall to the side is considerably warmer. In the bay window the studs are visible being much warmer than the infill.

Cold point being 5.5c, mid wall 8.2c and curtains 12.4c. It’s ~6c outside.

SW #retrofit: a new 7-line font for the Alphasmart Neo, created using vintage software

reddit.com/r/writerDeck/commen

The LCD screen of an Alphasmart Neo. The text reads:
Hello there, this is a Courier New font, which I made through the Mac Font Editor Program. There is a function that allows you to import existing Mac fonts into the editor. Admittedly most are pretty bad. But this one seems pretty good, and has a full seven lines of text.

I'm surprised to learn that there are now air-to-air heat pumps, which you can install yourself and which are cheaper than (wall mounted) oil filled electric radiators to buy, and 4x cheaper to run e.g.:

The energy companies that have dominated #retrofit programmes and supply chains at arm’s length from government scrutiny for at least a decade are panicking because they’ve been called out for their incredibly poor work.

Yes, this retrofit and insulation work still desperately needs to be done, but #ECO has spectacularly failed to be the vehicle by which to do it.

It's a big day for us: we're moving into bigger premises! This will allow us to increase production and take on more staff.

Our Petflap #draughtproof pet door is hand built in the UK by a family firm and shipped worldwide. The Petflap is often fitted into #passivhaus, #retrofit and other low energy homes. We build bespoke models, can build in a microchip catflap, and also make The Midiflap for dogs and larger cats.

You can find us at thepetflap.com/

retrofitted - the future of vehicle building

#hydrogen #retrofit #fuelcell
You see a front perspective of the motor compartment of a pulley for airport ground handling operation modified for hydrogen fuel. Parts of the diesel engine construction were kept, like the cooler and even the lead battery - because good, here and usable.

It's good to see that GMCA has adopted a retrofit framework agreement that includes calculating embodied carbon.
As we showed in relation to GMCA's own Joint Development Plan, Places for Everyone, it's embodied carbon that's the big problem in building new homes etc. So at least try to make #retrofit and enetgy saving low carbon.

Even so, I saw first hand the potential for poor design, installation and regulatory compliance.

The industry is very fragmented and too much trust was put in consultants to have oversight of projects for #DESNZ. These consultants rarely had to go to site and had no trade/on the tools knowledge of #retrofit installation.

Subcontracting is another big issue. The accreditations might have been held by a ‘principal installer’ but that was meaningless in terms of who did the actual work.

Well yes…adaptation to buildings will be necessary in a country where temperatures are set to rise by at least 2C.

But article gives no ideas as to what adaptations or potential costs would be.

We’re past ringing the alarm bells…they’ve been rung for decades and no one is listening.

We need to be talking insulation, ventilation, shading and orientation of new builds.
