Enlighting that the toilet can waste so much water. Since it is such a heavy user, more efficient fixtures should be a high priority.

The details of how a toilet operates is not something I've given a lot of thought to. The amount of water that can be saved through the use of a highly efficient toilet is amazing.

I like the courses taped from the Greenbuild conference in 2019. I felt like I was at the conference without going- saving energy and cost! However, a little more focus could be spent on the slides when compared to the video of the presenter- too much video of him walking around and the two participants at the front of the expo seating area not paying attention. Would have liked the course to include a section on commercial flush valves.
