...yeah, like the experience of hypo- and hyper-thermia.
I worked for one of the UK's largest software companies once, during which time they moved into a refurbished mill building. The ceiling was more than ten metres up, and corrugated steel. It was February, and there were lots of projects approaching deadlines. They bought us duvets, sleeping bags and fingerless mitts. You get into the sleeping bag, then sit on your chair - the wheels are complete bastards, when you're in a mummy-style sleeping bag - then throw the duvet on top and 'start clicking'. If you didn't drink your tea as soon as it came, it froze in the cup. They did eventually fit an insulated false ceiling. I think I bought a new car with my overtime payments. They tried heating the space, but they spent a small fortune on heaters and people got sick from having one side of their body toasted while the other side froze.
Now I live in a 3-bed house in Malaysia, only a stone's throw from the equator. The thermometer by my desk tells me it's 31C, but there are no clouds today, so the humidity is low enough that sweating works. It's not lunchtime yet, so the house is still comparatively cool. After lunch, I'll put the aircon on in the study (where me and my wife work) on. It's set for 27C, which with a slow ceiling fan is good enough. Any cooler, and we lose all enthusiasm for walking the kids to school, or doing household chores in the rest of the house (which isn't air-conditioned - aside from the bedrooms).
A few months ago I had a search engine running on several servers in the study, and we used about a GW hour per month. Since it was moved out, we use about 600 kW hours per month - mostly aircon, instant water heaters for showers (no hot water plumbing), and boiling water for drinking / cooking. We have one server that runs full-time. We bought the previous one new from "Lucky Fortune Computer Supplies" and it was noisy and hot, so I put it on a power meter and it used 200W. I took the power meter new server shopping and got something cheap from Dell that uses 50W - that's a 100kW hours per month better off. Electric supply is dirt cheap here, but less power is always cheaper.
