When we moved to Chevy Chase from CA the energy crisis was on and , while they shy had served the (rental ) house for years, they claimed we were a new customer and the had not responsibility too serve us. We had only a few hundred gallons of heating oil and Betty cranked the temperature way down because we thought we might not get any more. After a month or so the oil company relented but for a while we were running the house in the mid 50s!\
Is there some assumption that everyone has A/C? We use night-flush and passive measures (eaves, roof garden) for cooling (and can attest to the potential for humidity issues; now considering a heat pump).
because the study area is so warm, we are assuming everyone in the dataset has AC
Of course low income folks may not be able to afford the newest energy efficient Acs. May only be able to afford second hand inefficient old units.
Is that known to be true? People were living in Arizona long before the advent of A/C. (granted, now we have climate change on top of the usual factors)
Could older (more costly) housing require less active cooling, by design?
I’d think so — both energy efficiency of equipment and presence of passive features likely add to the equity gap.
Is it assumed that all populations are equally tolerant to heat? I wonder if there are different heat tolerance ranges per ethnicity group, and if this could make different temperatures achieve the same level of comfort for different groups...
What is the electricy price in AZ?
10.5 cents/kWh per the latest (2019) data released in November 2020
Very well done!
back to the AC question, most households in the dataset uses "Heat pump (same system heats and cools using electricity only", which is ideal for our analyses, because we only electricity usage data (and not gas), this way the curve we plot for each household captures their energy-dependent energy usage
When I visit family in TX (in August), I bring long sleeves to protect myself from the A/C run amok.
Perhaps those show-offs are also trying to show off their sweater collection…
My mom would always send me to the mall or the library during the summer for AC
and movie theatres...
Probably more malls open now than movie theatres.
Kids are not in school during the summer, in part because a lot of schools don’t have AC
Shoutout to ASHRAE 🙌🏽
Not sure about Arizona, but the school year in Texas begins the second week of August.
Another factor in temperature expectations in businesses and institutions is the dress code. Men in business suits presumably like things cool (and then women either need to wear sweaters or suits or other heavy clothing).
So allowing more casual dress might result in more seasonally-appropriate clothing.
Speaking of windows — were you able to correct for the presence of eaves?
phoenix doesn't really have trees (some palm)
there's some pines in phx
Thanks for sharing we will keep that in mind. lots to investigate here
Great talk Destenie!
Thanks — great job, Destenie!
Great work, Destenie!
