While student test scores may improve, the long term impacts of conditioning everyone to cooler temperatures could be maintaining the populations' devastating energy consumption.
It seems quite misleading to claim that the only benefit of energy consumption is improved test scores.
"each 1F increase in average temperature associated with 4.5% lower GDP per capita"
"Heat may indirectly impact learning... on agricultural income, nutrition, and the opportunity costs of schooling in developing economies and on economic activity, institutional norms and political stability."
"Heat may also impact learning directly by altering human physiology and cognition. Even moderately elevated
temperatures can impair decision-making "
Any impact of sitting (do you have cites/references to support your suggestion) does nothing to change this data, and I'm not a supporter of "we can only address one topic at a time" arguments. Being active or having A/C isn't an exclusive either/or.
Reducing energy consumption at a cost of poor learning, lower education, poor nutrition, lowered GNP, political instability, reduced cognition, and impacted physiology is a bit more impactful than low test scores.
