"Only when your own problems are solved can any green measures become really effective.

"Today, with the country's households earning more, they're concerned with the quality of their life," says Wu.

Green, healthy and smart living spaces are where society is heading now. And energy-conservation is one requirement you can't overlook," he says.

Around 80 households in Beijing went through such facelifts by the end of 2015. Shanghai has recently started its own program.

During the 2015 Climate Change Conference in Paris, FoN showcased what the low-carbon household project had achieved in the past few years in China.

Wang, the project manager who shared the cases in Paris, says: "Similar things can be done in households around the world.

"We are all chipping in to see what everyone can do to shape our living space a little better."

Kong Xia, another Beijing resident who renovated her apartment the low carbon way last year says the energy-saving tips are the most popular posts on her WeChat account right now.

"From a DIY your own air-cleaner to fermenting your own enzymes, these are things that people really want to read about," Luo says.

"We are only ordinary people, there is nothing avant-garde about what we've done," she adds.

"But just these simple things can bring about a palpable difference."
