With a glass of Ardbeg, even 3 degrees more would be quite bearable indoors...

Yes. We are in the house building forum. ;-)

We are mostly in the "air-to-water heat pump consumption thread," which naturally focuses on existing installations ;-)
Or do the contributors just make up their (indoor) temperatures? I don't think so.

Edit: It’s 21.8 degrees.

In general, hardly anyone thinks about the topic of shading.

Despite having a controlled residential ventilation system, the humidity levels are really problematic. I had the dehumidifier running in the basement this morning and now on the ground floor.

You have to accept one problem or the other. Either irrigation costs and very low humidity because there’s no rain, or rain and high humidity. It hasn’t been this cold and wet during the first half of the year in the past three years.

This morning we had 100% humidity, so it wasn’t even possible to ventilate out the heat.

It's been quite heavy today, but yesterday evening we had a short burst of 35 liters in 1.5 hours (9.3 gallons). It was intense, including a power outage for a few minutes.

In our basement light well, water was pushed in. An initial assessment showed that strong wind and heavy rain forced water into the well, and it couldn’t drain away quickly enough. As a result, there is about 500ml (17 fl oz) of water around the window seal. I wiped it up with a cloth.

However, if this situation continues for several hours, the basement could be significantly flooded. I plan to build a light well cover for these cases and place it over the opening.

Otherwise, the humidity in the basement is high, around 68%. I am now running a dehumidifier. Washing and drying clothes also contribute to the moisture level...
