Obituary - The Wrong Time[^]
I've been pretty busy yesterday, but better late than never!
Obituary is a legendary death metal band, and as such I've known their name for about twenty years, but never really listened to them.
Their new album got good reviews and one magazine even called it their best release in their nearly 40-year history, so I decided to give it a listen.
Since they're from Florida I expected it to be like Morbid Angel or Cannibal Corpse, but I was pleasantly surprised!
I certainly did not expect mid-tempo and groovy death metal.
The album's been on repeat ever since.
Sound of the week!

Nice one!
I think I listened to some of the singles before this was released, but never heard the full album.
Already listened to it three times this weekend

Nice one too, but I'm somehow more in a metal state of mind

good .. but, in my case, it seems that I am addicted to "more bpm"
and ... psssst ... I keep something related to it for next SOTW, really a lot of bpm ...

Yeah, I know the album and the song.
Good stuff, but not too often.

coldest day here in upstate New York in a long time.
My boiler at the house is working its butt off to keep us warm at 65 degrees F.
Fireplace in the game room is roaring.
Old house with base-board heating - ugh.
I just noticed that the brass front door hinges are frosted over completely white on the inside of the house. Some of the windows where the seal is not so tight is frosted over as well inside the house. One can only guess how much energy I am losing to these poor seals and cracks. You win some and you lose some - it could be a lot worse.

The wind chill here in Ottawa was -40 yesterday. That's the temperature at which C and F coincide.

yeah, I don't even want to think about temps in areas north of me. No thank you. You can have it.

In Montreal area, we currently have -30 (wind chill -41). But cheer up: in Resolute is "only" -34 so it cannot get much worse

In New Orleans, when it gets down to 42:F We all freeze to Death.

A long time ago, when I live in Los Angeles, CA, 45 was considered cold, too. Little did I know...

Same in Montréal, 3 days at around -25c
I wanted to go for a walk on the mountain, but I can't find my long johns; just too cold otherwise.
But from tomorrow, we'll have an above 0c weather for at least a week.

Where I grew up and went to school, we were kicked out of the buildings for 10 / 20 minutes between classes, to breathe fresh air and have some physical activity - but if temperature went below -20C, we were allowed to stay in the corridors. Lots of us went outdoors anyway; we didn't consider it to be 'real winter' at much less cold than that.
There is an important side to it: The winter time air was almost as dry as a desert. And 'wind' was some strange, unknown phenomenon that we could read about in the newspapers, something they had in places remote from ours 
Bottom line: The temperature alone doesn't tell very much. Humidity and wind are essential. That's why we refer to 'wind chill factor'. But it is relevant only to the human experience of the cold!
One thing that lots of people are not aware of: The 'wind chill' has to do with evaporation from your skin when you are outdoors. That cools the skin down, and may give you frost bites. But, your house doesn't sweat. It doesn't loose heat due to evaporation from its outer surfaces. So your heating requirements depends on the air temperature, but not on the wind chill factor!
If you have an extremely poorly insulated house, you might have a very slight effect of the wind: In absolute windstill, heat loss might heat the surrounding air to lay as a slightly warmed blanket around your house. But even the slightest puff of wind will blow it away; the effect is so small it isn't worth considering. If you insist that wind cools down your house: Yes, that may be true, if you have ventilation that will let more hot air out of the house when it is blowing. Or for that sake, any hot air leakage at all, even if is was never intended to be 'ventilation', where the wind can suck hot air out of the building.
For at least 40-50 years, Norwegian building standards have required walls to be absolutely air tight, inpenetrable by wind. For not quite as long, passive ventilation through vents in the walls have been banned: All air replacement should be centralized, so that the heat energy of any hot air leaving the building can be transferred to the fresh, cold air being sucked in. I'd think that such requirements sound crazy in Florida

Allow me a mini poll:
How are building regulations in your country with regard to minimum insulation?
Are you allowed to put up a new home from walls with no insulation whatsoever? Or are there minimum requirements to what is commonly called the 'U value' (earlier, it was called the 'k-value') of outer walls?
The U value, in its metric version, is given in Watt / SquareMeter*TemperatureDifference. If your living room has an outer wall of 2.5 * 6 meters, i.e. 15 sqm, your indoor temperature is 20C, the outdoor temperature is -20C, and the wall has a U-value of 0.1, then your heat loss is 0.1 * 15 sqm * 40 K = 60 W. To keep the temperature unchanged, you need a living room heater of 60 W under these conditions.
I believe that Norwegian requirements are rather extreme, with U=0.13 for the roof, 0.10 for floors, 0.18 for walls and 0.8 for windows. Is your country/state anywhere close to such requirements?
For U values in 'English' units, there will be a simple multiplication factor to metric. I don't know which units are used - probably square foot and temperature in delta F. I assume that those who can provide English U-values can tell about the units!

On the left side of the pond we use the R-value[^] which is 1/U (just to be different). In southern Quebec minimum values are R-41 for the roof space, R-24.5 for above-ground walls and R-17 for foundation walls. (see this)[^] That would make something like U=0.3 for roof, 0.4 for walls and 0.6 for foundation walls.
Edit: R values given are in imperial units. They have to be multiplied by 10 for metric units.

Thanx Mirea for the clarification and conversions.

If U = 1/R, you made 10x math errors.
1/41 = .024
1/24.5 = .041
1/17 = .058
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

No, I was accounting for imperial/metric units. The U values are given in [W/m2*K] while the R values are in [K*ft2/W]. When given in metric units, R values are usually called RSI (like R in SI).
Given that 1sq m ≈ 10sq ft, I multiplied the 1/R values by 10.
