Building Passive Houses

"The passive-building standard is only now getting off the ground in the United States—despite years of data suggesting that America’s drafty building methods are wasteful."

"To date, Passive House Institute-U.S. has educated about 160 builders, architects and engineers in the standard through a series of training programs and a final certification exam. By year-end, the number is expected to be 300, and Ms. Klingenberg said the institute was having difficulty meeting demand for its courses. But this sort of building comes at a premium, particularly in the United States, where the fledgling movement is trying to ramp up from scratch and has to rely on products supplied by a market that is geared toward less rigorous programs."

With a robust U.S. stock market and GDP and low unemployment figures, it’s easy to see why some think all is well. But looking at real U.S. wages, which have remained stagnant—and have, thus, in effect gone down given rising costs from inflation—a very different picture emerges. For the 1%, the economy is booming. For the rest of us, it’s hard to even know where we stand. A recent study by Porch (a home-improvement company) of blue-collar vs. white-collar workers shows how traditional categories are becoming less distinct—the study references "new-collar" workers, who require technical certifications but not college degrees. And a set of recent infographics from CreditLoan capturing the thoughts of America’s middle class as defined by the Pew Research Center shows how confused we are.
