To bangkok office workers, it's pretty natural to blast the AC all day and have the office still be above 28'C
Furthermore, unless you're in an area of the country that requires the use of a lot of AC--or you have electric baseboard heat--insulation doesn't even play that much into electricity usage.
On insulation, I'm assuming you mean in areas where AC isn't heavily used insulation doesn't help electricity bills if heat is provided by gas/oil?
Correct. Heavy use of electric heat is fairly uncommon as it's relatively expensive. (In the Northeast, it would be considered a serious negative if a house had only electric heat.) Of course, insulation helps with overall energy usage if there's either a lot of heating, a lot of cooling, or both--however it's provided. I'm also sure the US tends to have larger houses, more large electric appliances, and other home features that increase electricity use.
Two things: 1) I wonder how much energy could be "saved" with proper insulation. Per Country, per planet. 2) Insulation seems like a human sense, by that I mean, whenever I've lived in an old, stone wall house, I enjoyed the delay in temperature. It's still refreshing when the sun hits hard, and still mildly warm when cold settles.
More efficient lifestyle and better quality of life ? I'd sign.
Clearly, there is lot to win here,with existing insulation techniques. we could do a lot in a short-term with existing technologies, it's mostly policy and financing issue.
That may have changed in the recent years, but holds true for most residential properties built before 1980.
