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.
