Certainly the comfort band is the key to it. Everything else is rounding error under even the most pessimistic estimates.
On phase change energies: I don’t know enough to quantify things definitely there, but https://en.wikipedia.org/wiki/Latent_heat#Specific_latent_heat_for_condensation_of_water_in_clouds https://en.wikipedia.org/wiki/Latent_heat#Specific_latent_he... looks like the right thing, and suggests around 2.4kJ/g, which with water being as much as 5% of the air (100% humidity at 40°C) would be as much as cooling the air down by about another 0.12°C for removing all of it.
- mlyle 5y agoEach of the terms is a small single digit percentage, but they multiply together to become a small but noticeable effect on building efficiency.
- chrismorgan 5y agoEach of the terms are single digit percentages if you were completely replacing cool, implausibly bone-dry air with implausibly hot and saturated air. With more realistic ambient and goal saturation, temperature and leakage figures, I think you’re looking at more like single digit hundred thousandths or millionths for most of the terms.
- mlyle 5y agoI disagree, and you can take it up with the people codifying energy efficient building standards and working on compliance with them if you care. :P
