International Comparisons
International comparisons of particular note include:
- The 1977 Danish BR77 standard (the first to set demanding energy efficiency requirements).
- The SBN-80 (Svensk Bygg Norm) 1980 Swedish Building Standards, which in 1983 was in advance of the UK 2002 standards.
- The voluntary Canadian R-2000 standard, to which around 14,000 houses had been built in the 10 years to 1992.
Since then many more have been built in Canada, in Japan, and in various other countries including a number in the UK. Currently energy savings of 30% to 40% are typically achieved in Canada.
- The voluntary German Passivhaus standard. Properties built to the standards use approximately 85% less energy and produce 95% less carbon dioxide compared to properties built to the UK's 2002 standards. Over 6,000 such houses have been built across several European countries.
- The voluntary Swiss Minergie standard which requires that general energy consumption must not to be higher than 75% of that of average buildings and that fossil-fuel consumption must not be higher than 50% of the consumption of such buildings, and the Minergie-P standard, requiring virtually zero energy consumption.

Famous quotes containing the word comparisons:
“I don’t like comparisons with football. Baseball is an entirely different game. You can watch a tight, well-played football game, but it isn’t exciting if half the stadium is empty. The violence on the field must bounce off a lot of people. But you can go to a ball park on a quiet Tuesday afternoon with only a few thousand people in the place and thoroughly enjoy a one-sided game. Baseball has an aesthetic, intellectual appeal found in no other team sport.”
—Bowie Kuhn (b. 1926)
