The assignment is due before July 14. The site indicates that each week is approximately 8-12 hours of content and work. There's a bunch of extra resources listed on EdX.
I've already watched these lectures videos but I guess I'll watch them again. Slides are here. Online energy converter here. Interesting US energy flow diagram here.
Conditioning loads are the energy used to control the environment in a space, constrast with internal loads which is the electricity used on lighting, appliances, etc.
In buildings we use kilowatt hour to measure energy (as opposed to a joule). For heating and cooling we use British Thermal Unit (BTU).
Sense is a potentially interesting product for measuring energy use. Here is an EPA power profiler that is also interesting.
Energy Use Intensity (EUI): Add up your energy use and divide by sqaure footage to get a number in kWh/m^2/yr or kBTU/ft^2/yr. This is common but has some problems. The good thing is that its so easy to get.
My utility company says I used 1,944.23 kWh of electricity in 2019, and the area of my apartment is 483 sq ft (44.87 m^2). This gives an EUI of 43.33 kWh/m^2 year (4.03 kWh/ft^2 year). Which seems pretty good. Looks at my budget app history I think this cost me $274.13. I think this is a pretty small footprint, that said it does look to be increasing this year.
I learned that there's no LEED bronze, which is kind of funny. LEED comes up a lot at work so its interesting to get a slightly more critical take on it.
The Energy Star Target Finder is a useful tool.
I found all three questions pretty straightforward.
The third question uses the LBNL Building Performance Database. And references this useful climate zone map.
Of interest, I think I am in climate zone 4, but its hard to find a map of climate zones for Canada.
