Villanova officially has the highest number of homes for sale with energy-saving or “green” features, according to a survey by online brokerage firm Redfin, writes Sandy Smith for Philadelphia Magazine.

The survey found that environmentally friendly features were included on 57 percent of home listings, placing Villanova at the top of “The Top 10 Neighborhoods for Green Homes” ranking.

Redfin searched for terms such as LEED, Energy Star, solar, and energy-efficient in home descriptions when compiling the list. Additionally, the Seattle firm found that these features can significantly increase a house’s value.

The survey also noted that the majority of homes on the Main Line are greener. According to Tom Lewis, Redfin’s Philadelphia market manager, this is due to how they are built.

“It seems that on the Main Line especially, there are a lot of older homes that are conducive to retrofitting with today’s green technology,” he said. “You see a lot of brick and stone homes that have great bones to work with, and you can make these more energy-efficient.”
