The quiet rage I feel as a Passivhaus consultant living in a 5-year-old house that overheats horribly every heat wave, knowing how simply some minor design changes, shading and MVHR could have avoided it completely. Sitting here contemplating simplest way to retrofit MVHR and shading.

Keeping the sun out is a lot easier than trying to cool the house afterwards. Wish I could do upstairs too, and that UK standard house design was actually fit for purpose. 25 degrees inside and rising, but rising much more slowly than without the blankets.

Blankets hanging over the outside of patio doors and a window, to stop the sun getting in, at the back of a modern semi-detached house.

I just read a planning application to convert a historic storage building into a shop and flat, and now I'm angry. Not because they want to convert it, but because my 84 m2 two bed semi-detached house (which feels like a luxury to have to myself) would fit into their proposed 3 bed flat 5.7 times!

Writing some course material about sustainable building materials. Started writing that the standard LCA approach was detailed on environmental impact but ignored social sustainability. Thought: must check this is true. It is NOT! The framework standard very much includes social sustainability

I can feel the draught coming in around the outside of my window frames. This house is only five years old. To fix this properly I'd need to hack into the plaster all around each window and remove the cills. Such invasive work shouldn't be needed in new houses, but frequently is.

I’ve very much neglected this account. General life pondering and rubbish-talking now happen on my other account. Not sure how many of the Passivhaus/low-carbon/low-impact construction people are still active on here, but just in case: Hello! [waves].

It's national Get That Slightly Squeaky Fan Out of the Loft Day for those of use that don't live in a house where overheating risk was properly considered. It's already 24° in my office but the air movement from the fan helps it feel more comfortable, squeak not withstanding.

This episode is amazing. If you want to know what it’s actually like being autistic (as opposed to the stereotypes) it’s a must-listen. I’m autistic & this episode is just about the most validating thing I’ve listened too, ever. Also, effing funny. Also the best (wholly justified) righteous rants.

UK MPs: 1. The Supreme Court ruling is not "the law", nor has it changed existing legislation. 2. The EHRC's interim update is also not "the law". It isn't even "guidance". 3. The upcoming EHRC guidance, likewise, is not "the law". Again, the legislation hasn't changed. 1/

Good things: 1. Finally able to concentrate on work again enough to make progress through the first of several late reports 2. Coffee break in the sun outside my back door, staring at the sky 3. See my first swift of the year gliding about above 4. See a Kite (the bird variety) drifting about above

Watching a very depressing but incredibly useful smoke test video of a post retrofit house. Lots of leakage at floor to wall junction (suspect leakage through floor, and wall not properly sealed to floor), and a fair bit around windows (both through window seals, and join of window to building).
