Going green is a trend that's swept across the nation over recent years.
As that push continues, we seen "green" techniques popping up everywhere, including homes.
Channel 6 took a tour of an energy efficient home Saturday as part of a the 2013 Green Home Tour across the area.
Ken Mayer and his wife spent the day giving tours of their home.
Visitors like Peter and Pam Parker weren't just checking out the home decor, or the landscaping. They were also looking for new ways to be energy smart.
"We're familiar with it, but it just gets newer and newer, so if you don't do this every year, you miss it," said Peter Parker.
Mayer and his wife have spent the last five years renovating their house.
"We started doing improvements and remodeling, but we did that with an eye towards saving money on our energy costs," he said.
The Mayers started by replacing all of the windows with energy efficient ones.
Then, with the help of an energy auditor, plugged all air leaks with calk or foam, and added insulated siding to the house.
They got a furnace with 95% efficiency. "It is more thoroughly using any fuel that's put into it," Mayer said.
The Mayers also bought something called an energy recovery ventilator. It cleans the air, and helps keep the home's temperature. "It's giving the heat that's pulled out of those bathrooms in that air, and it's putting it into that air that's coming in from outside," said Mayer.
In addition, they purchased a high efficiency heat pump that heats and cools the house.
The Parkers, along with others taking the tour, realized the benefits of being energy smart.
It's not just better for the environment, but it'll end up helping with someone's pocketbook.
"It's all about saving money. It's about retiring eventually and being able to know you're not going to have wasteful payments if you're on a fixed income," said Peter Parker.
Six other energy smart homes across the area were part of the tour.
A Smart Energy Expo was held at Millard Lumber.
