Green building is getting smarter. As prices for expensive technology drop, builders are going to start implementing innovations that will drastically increase the energy-efficiency of tomorrow's homes.

Greener Ideal's list provides a look at where the green building industry is headed. Smarter insulation, energy efficient appliances, and better use of energy will all play into the next generations of green homes.

Builders are already showing off some of these technologies, and making really cool houses.

While these advances will certainly reduce our carbon footprints—look for them to benefit residents in other ways, like financially and physically. Residents of energy-efficient homes are generally healthier and less likely to default on their mortgages.
