In the summer of 2020 I took the online course MITx 4.464x: Sustainable Building Design through edX. My interest in the subject primarily comes from being exposed to some related concepts at my day job and a desire to learn more about the wider field. While I've completed one or two MOOCs before, this was the first time I paid for access to graded assignments and a certificate at the end. My hope was that investing the money (~$70) would make me more likely to follow through with the course, which seemed to work since I completed the full course.
I took the notes below while watching the lectures. They're in no means comprehensive but serve as a fairly good reminder to myself on the content covered in the course. They're likely of limited value to anyone else.
I've since written a slightly more presentable review of the course here.
