Hi Ed;

That is nothing but a fantasy. There is no truth to it. Ground
temperatures at a depth of 10ft swing about 10°F between there
highs and lows. At 5ft down, they swing about 20°F. Stable
temperatures do not occur until about 30ft down.

Modern energy efficient above ground houses are also so tight
that they often require mechanical ventilation, in order to have
adequate fresh air. Back in the 1970s, when above ground
houses were virtually always under-insulated and leaky, an
underground house would have been a superior strategies
that would produce better results. However, with today’s
far higher standards for above ground houses (as well as
very efficient heating/cooling systems) building under-
-ground just adds expense, and drastically lowers
resale values, without improving energy efficiency.

There is no mention of where the house is located in Canada.
Something like 75% of Canadians live within 75 miles of the
US border, many in climates that are warmer and sunnier
than many US locations. For instance, where I live, in
Northern Michigan, for about three months of the year
South facing windows lose more heat than they gain, even
though they may gain a little more, on an annual basis.
The article sounds like the standard rhetoric of the 1970s.
It was generally valid then, but not today, now that
above ground construction houses are built so much better.
