What is an energy-efficient home?

Any home can be more energy-efficient

Any home, no matter when it was built, can be energy-efficient. Modern construction standards demand greater energy efficiency in new homes, but older homes can be upgraded to improve their energy performance. And the people living in these homes can be energy-efficient in their habits, too.

An energy-efficient home is…

House with energy efficiency features.
