When we think of green buildings, we tend to think
of new ones–the kind of high-tech, solar-paneled masterpieces that make the
covers of architecture magazines. But the U.S. has more than 100 million
existing homes, and it would be {{U}} {{U}} 1 {{/U}}
{{/U}}wasteful to tear them all down and {{U}} {{U}} 2 {{/U}}
{{/U}}them with greener versions. An enormous amount of energy and resources went
into the construction of those houses. And it would take an average of 65 years
for the {{U}} {{U}} 3 {{/U}} {{/U}}carbon emissions from a new
energy-efficient home to make up for the resources lost by destroying an old
one. So in the broadest {{U}} {{U}} 4 {{/U}} {{/U}}, the
greenest home is the one that has already been built. But at the same time,
nearly half of U.S. carbon emissions come from heating, cooling and {{U}}
{{U}} 5 {{/U}} {{/U}}our homes, offices and other buildings. "You
can't deal with climate change without dealing with existing buildings," says
Richard Moe, the president of the National Trust. With some
{{U}} {{U}} 6 {{/U}} {{/U}}, the oldest homes tend to be the
least energy-efficient. Houses built before 1939 use about 50% more energy per
square foot than those built after 2000, mainly due to the tiny cracks and gaps
that {{U}} {{U}} 7 {{/U}} {{/U}}over time and let in more
outside air. Fortunately, there are a {{U}} {{U}}
8 {{/U}} {{/U}}number of relatively simple changes that can green older
homes, from {{U}} {{U}} 9 {{/U}} {{/U}}ones like Lincoln's
Cottage to your own postwar home. And efficiency upgrades (升级) can save more
than just the earth; they can help {{U}} {{U}} 10 {{/U}}
{{/U}}property owners from rising power costs.
