Energy efficiency isn’t just for buildings anymore. Now, even your furniture can help lower your electric bills.

The ZeroEnergyFurniture Climatic Table sucks up heat from its surroundings, which cools the room around it. When the temperature decreases, it releases the heat. 

Created by designers Raphaël Ménard and Jean-Sébastien Lagrange, the table features phase-changing material inside a corrugated aluminum sheet under the tabletop. Like a wax, the phase-changing material softens once the temperature gets above 71 degrees Fahrenheit, soaking up excess heat from the room. When the temperature drops below 71 degrees, the wax hardens, releasing the stored heat back into the air. Thus, it acts as a kind of air conditioner that you can also eat your lunch on.

The design duo estimates that the Climatic Table can save offices up to 60 percent in heating costs and 30 percent in cooling costs. They plan to start selling it later this year. Previously, Ménard and Lagrange had released an eco-friendly charging station that powers your gadgets via solar panels.
