Put on a jumper. Or even, let your body adjust. There's plenty of evidence that keeping your body working to stay warm when you are healthy is very good forblood sugar control, which has additional benefits.
My house is extremely well insulated (BER A2), dunno if it qualifies as a passivhouse.
Also I'm exporting more than a megawatt per year back to grid for free, so you (as a society) may be happy.
So, I don't think I'm being unethical.
Do you take into account the energy needed to grow and transport the food you eat? To extract the material needed for objects you own? To build your car? To maintain the roads you use? I guess you obviously don't use fossil fuels at all and instead rely exclusively on the clean energy you produce?
Because if you don't, then you are still overall a consumer of energy.
But even if you were a net producer of clean energy, we as a society have a big problem of consuming too much overall. We will have to reduce that at some point (whether we want it or not). So it would be great if people started thinking about not eating meat for every meal, taking a plane every second week-end, and living in a sauna.
We as a society need to consume less energy (because we depend on fossil fuels that emit CO2), and anyway we will have less energy in the future (because... peak production of fossil fuels).
There is no price on that: we need to do less with less.
At this point I see zero reasons to conserve damn solar energy while half of the country still uses OFCH.
One way is to say "well I don't care, I won't do anything until I don't get a choice, and probably at that point it will hurt a lot".
Another is to face it, start doing things, and pushing your politicians to enforce very big plans. One problem I see is that everyone says "I would be ready to do a lot more if I knew everyone else did", but when it's time to vote, they don't.
Not being ready to go lower than 24.5 degrees (doesn't have to be 19 if that's not bearable for you) in winter does not sound like you are ready to do much, though.
As I said before, I'm living in a house insulated up to the highest standard, I have a heat pump and a solar PV, the largest PV array in the estate. I think this is something reasonable. I work remotely, I don't drive much and I drive with very good MPG, I've figured out that my car has the best MPG at 90 kmph so I drive about 90 kmph, I don't travel often, I'm carefully sorting my waste (most people throw everything into the black bin), I'm trying to buy things which last and I'm trying to repair and sell, I think if everyone does that it would make some reasonable impact.
Though I don't think that 19 or whatever degrees is something of your business.
> you are ready to do much
I'm not ready to do unreasonable (or idiotic) things. Why 24.5? Because I've figured out that it's the most optimal temperature for me.

Let's say that your case is extremely special and for you it does not make sense to not overheat, it does not make it unreasonable (or idiotic) to say that the vast majority of people should not overheat, does it?
