WEST LAFAYETTE, Ind. (WLFI) — Purdue graduate students live in a 90-year-old ReNEWW home to conduct environmental research.

This is due to a partnership with the Whirlpool Corporation

So the house they live in is going as green as they can.

It was retrofitted back in 2014.

ReNEWW stands for retrofitted net-zero energy, water and waste.

The basement holds a laboratory while the main floor has all the green gadgets.

It includes an induction oven, triple pane windows and a Biowall where plants help clean the air.

The house produces net-zero energy and water now, but the students are working on the waste part this year.

The students compost and recycle.

But sometimes it's hard work.

"It's really I think once I leave the home I will carry this on, said grad student Jessica Buschman. "I will try composting more, recycling more, using less energy."

Throughout the day, the graduate students were giving tours on how to live with more sustainability.
