Passivhaus

Part two of my lesson on standards was about Passivhaus.




I've written about Passivhaus before, and the video is based on this lesson: https://minuszeroeco.blogspot.com/2018/01/talking-about-passive-house-lesson-14.html

One advantage with teaching online has been more flexibility in time.

Classroom lessons are fixed at 90 minutes, which is great if you have one bit of content that takes 60 minutes to get through and another related bit that takes 30 minutes.

If you have two bits of 60-minute content, they aren't going to fit in one lesson in class.

They will fit online though. Sorry students! I'll make it up to you with some weeks with less content, and remember you can proceed at your own pace.

Setting standards

This is one of the most boring lessons in the course. Usually I would try to make it intactive by putting students into groups, telling them they are politicians, industry leaders, architects and building physicists tasked with making regulations to ensure low energy buildings are built.

Here is some information on video:
