Thanks for posting the video. We've been building houses for the past 60 years paying no attention to how much energy they use or what kind of environment they're in. I'm looking forward to the future when every person is more mindful of nature and the local environment they're living in.
This is an oversimplification. Sure, we haven't been making energy efficient homes. But consider that there was not really a reason to be energy efficient before now.
It's all about economics. The economics of the situation for the last 60 years have consistently called for cheap housing. That means bargain-basement quality, and bargain-basement materials.
I live in a CMU house. Until last fall, it had no central air and was on oil heat. We got tired of pouring $2k a year into that oil tank, so we spent $14k on new windows (the 1950 originals were still in there last year!) and putting in central air.
Considering that our electric bill is now 25-300% higher than before, depending on the weather, just those improvements are going to take about 15 years to pay for themselves. I'm looking at pressurized block-fill insulation companies now to see if I can get the electric bill lower, but with the added cost of that we're still looking at at least the same payoff time.
If the price of gas hadn't skyrocketed, we wouldn't have done ANY of this. Reason being, we're polishing a turd. Nobody is going to want to buy our house, except for developers, who will knock it down and put up a cheap, inefficient house which will sell overnight, considering our location.
If you really want to reverse this situation, then we really need to start pushing for zoning law change. There's a reason Manhattan looks the way it does... and there's a concurrent reason why the Adirondacks look the way they do. You could take 80% of America at this point and condense it into about 5% of the space it currently uses, just by revisiting zoning law.
Shopping centers are terrible. Shopping centers with 1,000 apartments on top of them are better. Shopping centers with 5,000 apartments on top and a subway station underneath are best. And when we get back to doing that, when the real estate is highly valued, then efficiency is going to be a concern.
Not before.
