My weather station tells me it hit 100F at 3pm. It was a bit hot in the factory today, under that tin roof.

You're dealing with outrageously hot and here I am in Texas dealing with outrageously cold. It snowed tonight! :D

My weather station here in Wisconsin says to expect a high of 20 F (-7 C) with wind chills down around 5 F (-15). And it snowed -all day- yesterday.

Wanna share?

At this very moment (about 6:30am), it's -17C (1.4F) with a windchill of -28C(-18F).

Ooh, on Sunday we're supposed to get down to -30. Time to get out the scarf!

How humid does Dubbo get in the summer? If it stays fairly low, swamp coolers (evaporative air conditioning) are cheap to run for warehouses and factory shop areas. Drop that 100-F down to a tolerable 80 or 85 when you provide enough crossflow to get the heat up and out.

You just have to be careful about the humidity getting up to rusting levels around tools...

Los Angeles is in that nice median band - not too hot, not too cold. At least when the ground isn't moving, and the hills are not on fire or turning into mudslides the next rain after... (No place is perfekt.)

It's glacial here in Salt Lake. That's why I love driving to San Diego in the winter, it's like visiting the tropics. Going in February...

I didn't say 'trade', I said 'share'. I figure between the two of us we can come up with a much more reasonable summer and winter temperature. Just ten degrees F would drop your temperature to 90, and raise mine to 30. (I like snow, so raising it much more would be bad.)

You're about to get the storm that just finished here in Wisconsin. Have fun!

Phew that is hot. I'd offer to trade our 60F and Rain, except that I do better in this weather than what you've got. Oh and by Friday, we'll be back down in the low 30's with possibilities for Snow.

Time to check labor laws for possible negotiation points.

During a late summer design/build crunch a metal building we worked in had the shut down during part of the build. Interior temperatures well above where they could legally require us to work. The team negotiated no dress code and they brought beer at 4pm. Work got done although some sales idiot decided to run some suits through at 5pm one evening. No shirts, no shoes, sweaty towels draped about and beers propped up by imaginative contrivances at every drafting station. Folks had an odd look on their face and we had no time for them being busy cranking out new work. Tis a fond memory.

What, they don't let you stand under/in the truck wash when it's hot? :D
We just had 6.5 inches of snow here.
I went without the AC this summer because of cost and it sucked, so I empathize. A bit.

Mid-summer humidity here when thunderstorms aren't in the area, is 5 to 10% When a thunderstorm threatens the % jumps to 70%. Almost every house in town has evap a/c. We have a big on on a stand the guys can move around and point at wherever they are working. Plus, there are double doors at each end of the factory so we can get a breeze going.

It's just that when the outside temp tops 40C, you can only get hot still air, hot moving air, or hot moist blowing air. Water consumption goes through the roof and productivity stops.

Lawn Sprinklers on the roof can help. Keep the heat from radiating in.

Add lots of attic insulation to keep the heat from from radiating down. Most of our industrial buildings are poured concrete "Tilt-Ups" with wood framed flat roofs, and they use radiant foil insulation - but Spec-built buildings they add fiberglass batts too. (Costs more, not required by Code, but makes a HUGE difference in HVAC costs.)

For steel framed industrial sheds you need to use the spray isocyanurate foam insulation on the inside of the roof, and/or the spray foam roof coating to add a few inches of insulation on the outside. (And it keeps the roof from rusting.)

And lots of turbine ventilators to get the heat out of the rafters.

If you own the building instead of renting, approach The Legal Owner (Dad) or the /Real/ Owner (Mom) ;-) with firm figures on how long the payback period is. They might let you fix it.

I have a swamp cooler, so I'm okay. You need to get out here to soak up the heat. 8)
