Air conditioning is baking the world

The city would require a person to mow their roof and rid it of natural medicines(sorry, I mean weeds) on a regular basis. That could be a pain but would create a lot of good paying jobs.

I have noticed this many times.

These people are really contributing to global warming in a big way.

They burn gas to run thier motor in order to operate the a c unit. This moves the heat from inside the car to outside, and the sun continues to heat the car at the same time.

The car motor heats up and the radiator dispells this heat out from the car.

This heat can be felt by anyone who walks close in front of the vehicle.

Can you imagine if 100 cars in the same parking lot were all running at the same time ?

I realize the planet will adapt to any conditions but, the question is --

Will any of us be here after these adaptations or will we want to be ???

I think this guy is the one that started both trends:

Climate crusader Al Gore did his part to warm the planet last week, leaving his car idling for an hour as he gave a lecture on sustainable development in Sweden

I don't use air conditioning but use Fans. And the extra electricity is about 20 dollars a month. We all should be offgrid living in earth ship homes as it is.

I recommend everyone who can afford it buy a swamp cooler, they're better than air conditioner, and if you own your own home, try to replace your utilities with homemade solar panels and wind, starting with conventional things and then going exotic, free energy.

No AC in our house either, we use fans too.

Swamp coolers are big here in southern Colorado. I don't think they work too well in humid areas though.

Because it's so arid our night temps stay in the low 60's. By morning the house is really cool and it stays comfortable all day. Although we have 90/100 degree days the cool nights balance things out.

What I find odd is that people in the little town near me are complaining of hot nights while out in the country we're enjoying extreme nighttime coolness. Maybe it's because the houses are too close together and air can't circulate or maybe it's all the pavement ?? After reading this thread it could be because everyone in town is running their air conditioning. Idk just seems strange they aren't as cool as us.

This issue has very little to do with the HVAC community, which has made tremendous strides in energy efficiency in the past couple decade.

The problem, is we have not adapted buildings to the extent that we have adapted appliances.

We still use R-value (U for those us north of the border) as the primary deciding factor on a walls performance...when R-values only tell you 1/3 of a materials insulating capacity...specifically thermal mass.

Until radiance, air infiltration (just starting to become big) and thermal mass are all considered equally, we will not address the core problem.

That's true. Reflecting the suns rays is a more sensible way of doing it. Trees cool the environment also, start planting more in the yards and the house stays cooler.

Nail meet head! Star for you.

We are constantly being pushed to use light controlling coatings, which is great, but a double edged sword.

Rarely do people push natural solutions.

You can get far more efficiency from plain old double pane sealed units (clear glass on clear glass) with a strategically placed deciduous tree than any of the newest coatings can give you.

Another simple solution is appropriate soffit depth. I see so many buildings in my area with 24" soffits, doing squat for the building...when a 36" soffit would provide shade to standard location windows in the summer, and allow full sun coverage in the winter. Yet, building code still calls for a minimum 24", which is what all mass production homes are built too.

The systems used in the US are very inefficient. Many factors contribute to an 80% loss of efficiency on average. Small, leaky, uninsulated duct work is to blame for much of it. We really don't want to invest in efficiency, being a bit short sighted.
