Wouldn’t it be nice to live in a home that uses less energy? Saving energy is not only good for the environment, it’s also nice to have lower heating and electric bills! There are numerous ways to save energy at home, but if you’re dreaming of a home that’s the ultimate in energy efficiency, take a look at the Passive House standard. This performance-based certification, which is already popular in Europe, is starting to catch on in the United States. It sets a maximum level of energy use per square foot of the house. Altogether, a Passive House will use an estimated 90 to 95 percent less energy for heating and cooling and 60 to 70 percent less overall energy than a typical code-built home. Builders are reaching this high level of energy efficiency by using high levels of insulation, high-performance windows and super-efficient ventilation systems.
