Heat

Rationally it makes sense to go for a run when the sun is setting because the heat from the sun is lower. In theory this means that the body is dealing with a cooler environment.

In practice, when I go for evening rides and runs my body remains warm for hours, and that heat, during a heat wave, in a minergie building makes it unbearable.

For a few days it was cooling, and I had stopped using fans. I questioned why. I suspect that it is because when the building is exposed to heat wave temperatures for several days the air heats, but eventually the buildings’ structure begins to radiate its own stored heat energy. This means that you’re dealing with hot air, which isn’t bad. It’s when the building becomes a radiator that it becomes unpleasant.

It’s worth noting that after my historical post was deleted from a group chat I aborted my run with that group. The reasons were rational, rather than emotional. Something else came up and by the time that something was over the run had started. I also expected it to rain very heavily and storm.

Yesterday the forecast was similar but I chose not to just sit at home and miss out. I could see that a storm was coming for 18:50 and again a few minutes later. I thought “If I wait too long it will be cancelled and I will have had a second day in a row without sports. That’s why I got dressed and cycled to the shop. I said “I expect the ride is cancelled”, and it was.

Yesterday morning I set two alarms for 0600 because I wanted to wake, have some free time, and then run at 07:50/08:00 but I don’t remember it waking me. I remember looking at the phone or watch and seeing 07:53. With the heat wave making sleep difficult, followed my a music festival making sleep difficult I reached such a point of exhaustion that the alarm failed to wake me. It even failed to register in my conscience that I turned off the alarms.

This morning it felt nice and cool so I spent as long as I could ventilating before the sun heated the Southern side of the building to a point where cooling was no longer effective. I went from 30°c down to 26°c very, very fast. The Outside Air Temperature (OAT) was 18-20°c so it’s a shame I didn’t capture more of that fresh air. The Long Tail of the heat wave comes as soon as you close the windows.

Minergie is a fantastic concept for a cold planet, and to keep cool in winter. It traps heat with ease during the morning and radiates it for the rest of the day into the night. It supplements to solar radiation heat with geothermal heat, which it gets from the heat pumps. That heat is then spread across the buidling with hot water pipes.

In winter this is fantastic because it saves on energy and provides a comfortable environment. In reality it’s not unusual for me to notice 25°c in winter, so in effect it might be too warm, for some.

Waking early is great, to run when it is cooler but it does have a serious drawback. That drawback is that whilst the run might be more pleasant, due to the fresher air, especially evening and morning rain but it has the drawback that if you live in a minergie apartment you never get an opportunity to flush out warm air and replace it with cool air.

Today, as one of my suntan lotion bottles is empty of suntan lotion I decided to clean it with dish soap and water, before adding water to use the suntan lotion bottle as a mister, and so far it has been a partial success.

Today I had the pleasure of going for a run early. I had planned to run at 07:30 to finish right as the shops were opening but I felt too lazy, so I was at the shops by 08:20 and running a few minutes later. I was thinking “Oh it’s still early, so I don’t need to run with water. That was a mistake. What wasn’t a mistake is choosing a course that passes by a number of fountains.

In the news they tell people over and over, “Don’t run in the heat” and don’t go out during the hottest part of the time" and yet they organise fan zones in Nyon, or other events in Asse and more. They tell us that we shouldn’t run, that we shouldn’t cycle but they don’t tell those that make sleeping even harder during a heat wave not to make noise.

Last night I went to sleep absurdly early by recent standards. I went to sleep before 2300, slept for about an hour and a half and then was woken, either by the dish washer that I programmed, or by geniuses (ironic) in cars beeping every few minutes after one of the football teams won the ugly game. Ugly because of the antisocial beeping of horns. Ugly because of the Royal Belge Football Club concerns about corruption within FIFA.

I see news reports and articles that say “Don’t do sports during a heatwave”, which, to me is bad advice. It’s not bad advice to tell people not to push and overheat at the hottest point of the day. It is bad advice not to say “Try to run in the morning” and “Be sure to have water nearby to help cool your body” or even “make sure to run by a river, in a forest, where evapotranspiration is possible.

In theory we will get a storm this afternoon and I am impatient for it. I am impatient for heavy rain to cool the roof and walls of this nightmare minergie building. As great as it is to have a cheap building to heat in winter, it is a deadly building in summer, especially when neighbours open their windows to aerate and let hot air in.

In normal buildings, if you open windows you get a draft, and that draft circulates air and it’s refreshing, and when you close windows that freshness lingers. In a minergie building, if you leave the window blinds open the sun heats every surface, and the air. The space heats up just like a car.
