I'll chuck in another "yes please" anecdote: A house I was renting took about 50,000+ BTUs worth of two large AC units to maintain around 90F during the summer. Our electricity bill would get pretty close to $500/month if it was hot (and down to <$20 other months). It was a house with a large, north/south-facing roof, with black roofing tiles, zero roofing insulation, and poor airflow (but lots of leaks) so we couldn't just open windows/doors. It was utterly absurd construction at even a glance (outside of fashion), and our utility costs were far more than it would've cost to improve. But the property owner lived elsewhere and had no interest in improving anything, only basic repairs.
