Pleasing. The MVHR unit doings its thing last night: external air temperature -3.5degC, incoming air warmed to 19degC by outgoing stale air. #EcoBungalow #passivhaus #passivehouse #enerphit #retrofit #mvhr #zehnder

Want lots of geeky detail about Air Source Heat Pump efficiency and space heating demand? You’ve come to the right place! #EcoBungalow #ASHP #PassivHaus #PassiveHouse #EnerPHit #Retrofit #PHPP

It used to be that if you were trying to reduce carbon emissions, you insulated and sealed, what's called "fabric first." Now that we have heat pumps, many are questioning whether fabric-first was the right approach. It's complicated... lloydalter.substack.com/p/what-the-h...

94% of UK Homeowners with heat pumps are satisfied with their heating. Yet social media is packed with claims that they don’t work in old houses, are expensive to run and are noisy. What’s the truth? New blogpost takes a look at the myths. #EcoBungalow #Passivhaus #EnerPHit #Retrofit #ASHP

So many houses in my street with windows open trying to cool down. But if it’s hotter outside than in this isn’t going to work! Dump heat morning and evening, and then keep everything shut for the rest of the day. Graph shows I wasn’t fast enough off the mark this morning! #EcoBungalow #Passivhaus

The MVHR either warms incoming air through the heat exchanger or brings it in at outside temp, bypassing the exchanger. Doing something clever today. Bypass is fully shut (so heat exchanger operating), incoming air ever so slightly cooler. Never seen this before. #EcoBungalow #PassivHaus #Retrofit

And the numbers are in! A full year’s energy use in the #EcoBungalow following its retrofit. New blogpost reports a spectacular reduction in kWh and a much, MUCH more comfortable home to live in. #passivhaus #passivehouse #retrofit #enerphit #ashp #mvhr #insulation www.ecobungalow.co/post/32-a-ye...

It’s not just about the building! Rewilding the garden is an integral part of the project. As a non-gardener, I’m amazed what I’ve achieved in a year. And surprised at the excitement of each new flower in the meadow! #EcoBungalow #Passivehouse #Rewilding #Retrofit www.ecobungalow.co/post/31-micr...

@flysas.com My mum died. I missed a flight. Insurance company wants you to confirm no refund has been issued to me. 3 phonecalls, 3 promises of an email. Nothing. At a loss as to what to do to get this simple statement from you. Please help.

Happy 97th birthday Tom Lehrer 🎂 Today, I'll be celebrating the birthday of the greatest musical satirist of the last hundred years. Born in Manhattan in 1928, Lehrer was a mathematician who wrote comedy and satirical songs, and became an international celebrity in the late 50s and early 60s. /1

For Americans who didn’t get the joy of living through the Truss/Kwarteng budget, this is the point where the government starts to call the stock market left-wing and/or woke.

Not enough snow on the Eagle Ski Club trip to Mar Lodge. But great walking and good company: interesting conversations with Penny and Martin, trustees of @thepebbletrust.bsky.social Recommend the trust’s excellent retrofit publication: www.thepebbletrust.org/sustainable-... #ecobungalow #passivhaus

Latest blog post. Energy use over the winter months: a dramatic decrease compared with pre-retrofit and a corresponding improvement in living comfort. #EcoBungalow #PassivHaus #Passivehouse #EnerPHit #Retrofit www.ecobungalow.co/post/30-ener...

I’m awaiting the first signs of Spring from my rewilded front garden. Will the new mixed native hedgerow burst into life? How’s the yellow rattle doing in the meadow? In the meantime this from #moderntoss made me laugh! #ecobungalow #passivehouse #passivhaus #retrofit #rewilding

Spectacularly terrible communication from Avanti about today’s strike. First an email to cancel the train. Then an automated email telling us that our journey is ‘all ready and sorted’. In what way?! Makes supporting sustainable travel much harder than it needs to be! #avanti #trainstrike

Good morning Paris! Ready for the least leg of the journey home: Eurostar to London and then onwards to Kendal (Avanti train strike permitting …) #sustainabletravel #gobytrain #skibytrain #skiing #skitouring #train #eurostar

Earning my turns! Superb week in the Tyrol with Alpine Guides. Now for the train journey home again. #Tyrol #Tirol #AlpineGuides #skitouring #skiing #sustainabletravel #gobytrain #train

On our way to Innsbruck by train for a week’s ski touring. Transfer from Gare du Nord to Gare de Lyon so much easier now with tickets on iPhone. Thanks @seatsixtyone.bsky.social for the top tip: game changer indeed! #sustainabletravel #gobytrain #RER #skitouring

What a relief to say goodbye rain, hello sunshine! Beautiful winter’s day walking in the #LakeDistrict. Now home for a hot shower: 21 degC inside, 0.3 degC outside. #ecobungalow #passivehouse #passivhaus #retrofit

Being green doesn’t necessarily mean sacrifice: @jeffcolley.bsky.social talks about the virtuous luxury of Passivehouse. #passivhaus #passivehouse #enerphit youtu.be/rktvTXnX2vE?...

It’s a condensation-on-the-outside-of-the-windows kinda morning. #EcoBungalow #tripleglazing #passivehouse #passivhaus #enerphit #retrofit #frostymorning

Made this reusable Christmas Tree out of driftwood a couple of years ago. Survived its time in storage during the building works. Lovely to get it out again ready for first Christmas in the #EcoBungalow #passivhaus #passivehouse #enerphit #retrofit #christmastree

Stunning winter’s day for a walk in the Lake District. Perfect reflection of the Langdale Pikes in Blea Tarn. Very chilly, so nice to get home to the steady 20.5 degC of the #EcoBungalow. #passivhaus #passivehouse #enerphit #retrofit #lakedistrict #langdale

Away from home for a few days. Keeping an eye on things with the Netatmo weather station. A frosty morning but still cosy inside. #EcoBungalow #passivhaus #passivehouse #retrofit #enerphit #netatmo

What a contrast! One year ago we’d achieved the airtight line at ceiling and floor levels. But the internal wall insulation hadn’t started and the windows were yet to go in. Today it’s a light and airy yet cosy home. #EcoBungalow #enerphit #passivhaus #passivehouse #retrofit #airtightness

Staying in a flat with a gas combo boiler. After six months with an ASHP with a max temp of 45degC, heating water so hot you have to dilute it with loads of cold to wash up seems an utterly bonkers way to use energy. #EcoBungalow #passivhaus #ashp #retrofit #passivehouse #energyuse

Pleasing. Outside air temperature -3degC, incoming air being warmed to 17degC by outgoing stale air. The wonders of Mechanical Ventilation with Heat Recovery. #MVHR #EcoBungalow #Passivhaus #Passivehouse #retrofit #enerphit #deepretrofit

So with all of the starter packs out there, it makes sense to have one for Passivhaus. I’m sure I’ve missed a lot of obvious accounts - partly through not knowing who has come across from Twitter and who hasn’t - so please flag up any you think of (especially if that’s you)! go.bsky.app/K4gWTBi
