Homebuyers have their quibbles and distinct needs, but everyone on the market can agree that using less energy means saving more money each month.
If you're on the market for a new home, consider finding one that's been Energy Star certified. There are strict requirements in meeting this voluntary federal program, and builders who do so are checked by third-party auditors such as the Center for Ecological Technology, a Bay State company that has certified 1,000 homes since 2003.
Take a look at what to expect in Energy Star homes, but be mindful that some of these efficient features may cost more than you're willing to spend.
