 Now that we know it's impossible to stop heat, let's see if we can slow it down!

How to Stop Heat

 

Watch this video lesson to find out! 

Spoiler alert: it's impossible to stop heat! You can only slow it down. If you want to lose less heat from your house, then the first thing to think about may be the surface area.

What is Energy?

 The first lesson. If you want a low energy building, this is the first question you need to ask. 

What is energy? How do you measure it? I thought of a dozen different ways. This shows how confused our language is over the science. 

In politics, language is power, but when it comes to science, power has a different and much more precise meaning. Heat seems like it's hot, but often it's not. In the next video, after explaining that heat and temperature are not the same thing, I described a difference in temperature as a difference in heat. In this video I used the word "precise" when I meant "accurate". I did this while I was talking about the difference between precision and accuracy. Maybe it's not the language that's confused. Maybe it's just me!

Anyway, this has nothing to do with the content of this video. You can read more about the lesson here.

Welcome to the course

University classes are online this year, so I've started putting the low energy building course into video. Here is the first, introductory message. (Warning: contains equations!)
