Heatwave!

And you'll leave an impression, maybe not a lasting one but an impression and you'l get a post-humous WWF gold medal.
 
Ah no. Like the purple shroud I'd say......sure don't you know and we all know that you are unique....
 
Seriously hot this evening - still showing 28 degrees at 8.21pm in South Dublin. I presume that's just air temperature but the radiant heat from buildings, pavements, walls and other surfaces must be adding a lot to that, making it seem even hotter. Barely a breath of wind out too - no sleep 'till Saturday!

Awake since about 06:15, nice and dry and bright and coooool. Joy of joys and I also managed to fix a pesky water leak without needing a plumber. I am the man!
 
Needed a fresh spell to cool the houses down before next heatwave arrives in a week. And some rain for the grass, gardens and reservoirs.
 
The wonderful thing about Green-onomics is that exactly the same things can be both really good and really bad - for different reasons or even the same reasons. Perhaps my poorly insulated 1970s dormer bungalow isn't the worst after all.

"Experts" really are fantastic people. They're always right - and when they're wrong, they're right too.


Dr Sirr predicted that in heatwaves it will be “suffocating” to live in an A rated home.

“Part of the reason that people have problems in A rated homes and is that is that they don't fully know how to use them properly,” he said.

“A lot of the standards that we have, like particularly when you get a passive house - [which] means it's generating as much kind of energy as it's using, for example.

“You can still have a lot of issues with overheating; so, it's a tricky one to manage.”



And when the sun shines more and it's hotter it's bad for the planet and for people. But it's also good in that more solar energy is generated, meaning less emissions - which is good for the planet.


Charlie McGee, EirGrid's System Operational Manager, said that June was yet another record month for the amount of solar energy powering the electricity system in Ireland.

"While this might have been expected given the sunny weather that we saw during the month, it is also reflective of the progress that we have made in integrating large grid-scale solar farms onto the system," Mr McGee said.

Lorcan Sirr is a housing economist, not a HVAC engineer or architect. He's as qualified to talk about this as a phycologist is to talk about history or sociology. He might be correct but only because he's repeating information from another source about which he is lacks the expertise to verify.

Climate change may cause warmer summers here and catastrophic storms and flooding in the winter. Nicer summer days are good, though the probability is that we'll have more humid and wetter summers as the Gulf Streams warms, but more severe storms are bad.

Was watching the "Six One" during the last heatwave in June and George Lee kind of tipped into this as well, that Irish houses now are more designed to retain heat then loose it which was closely followed by some university environment lecturer predicating that in 10 years time we'll look back at now and consider these summer heatwaves as cool ones!!

I'm the same but a 1960s DB and apart from the DB windows and Velux's in the roof and the attic insulated it's as it was built
I've never found the house cold and very rarely find the house hot but if I do I just open windows and doors to manage it
I often wonder about my neighbours around me who have done renovations to the new standards why I never see any of their windows open??

If an A rated house has a Mechanical Ventilation with Heat Recovery (MVHR) system then it will have a Summer Bypass function which stops pre-heating the incoming air.
Shading large areas of glass (awnings, closing blinds or curtains) prevents Solar Glazing.
Then there's the option of opening the windows.

Insulation stops houses cooling down quickly and therefore, obviously, stop them from heating up quickly. Opening the windows will cause more heat loss than bad insulation.
The up side is that if it's cool at night it takes longer for the house to heat up in the morning sun.
 
remember the advice during Covid by Dr Houlihan to open all your windows
Yes, and the guitar-playing Professor urging us for Christmas dinner to - quote: "Open the window, stick grandpa by the window, and [have a] good breeze blowing through it!"


Happy days indeed. (Follow the science.)
