Help with pool temperature

This is not intended to be another rant thread on the topic. There are more than enough of those here already. Our pool director just jacked the pool temp up. He said he is responding to complaints from the aquarobic folks and because the local schools are bringing kids in for lessons. He said it was 82 today, but I don't believe it. It's usually between 80 - 82, and it was a whole bunch warmer today. We couldn't really work out at all, and ended up just going back and forth. I ditched my cap for the first time in maybe 6 months, but it didn't help. We all got overheated anyway. Can anyone point me to a study about the hazards of a bunch of fat old dudes (and, of course, our much svelter dudettes) trying to go too hard in tepid spa water? Or any study relating to the dangers of overheating while exercising? It occurs to me that a pool that is slightly too cold for comfort for some may be an annoyance, but a pool that is too hot may be a danger. Most of the stuff I found after a quick search relates to pregnancy. I'm not even a little pregnant. As far as I know.

    The indoor pool I swim in is too warm for working out. Even the Master's Coach/Head Swim Instructor agrees, along with most of the masters, triathletes and lap swimmers. Written and oral complaints, suggestions, and even compliments (on the one day they lowered it to 82 during maintenance) have gotten nowhere. I read the previous posts and I'm going to buy a thermometer and collect the data. An angle I want to present is this: "You know, if you lowered the pool temperature just X degrees, you would save an estimated Y dollars a year." How do I estimate this? I assume I need to know the indoor air temperature, the volume of the pool, the current water temperature, the target water temperature, and the cost of energy. To be exact, I assume I would also need to know the rate at which the pool loses heat. I don't know how to estimate that. Can a reasonable assumption be made there? Its an indoor in-ground pool. Aren't they usually insulated from the ground? External air and ground temperature would play a role in that, too, I assume. Does someone have an EXCEL spreadsheet I could plug these things into and produce a cost savings analysis? Surely there is an Masters swimmer with an engineering background out there that could pull this together and help us all. I don't know how the numbers will turn out, but this could be a very powerful argument to make to the management. Thanks !!
