0 ENERGY

0 energy

0 energy refers to buildings with an annual zero net energy consumption. This means that 0 energy buildings in principle can be used autonomously from the energy grid supply, as energy can be harvested on site for example by wind turbines or photovoltaics (solar cells).

A 0 energy house is the logic development from passiv houses towards energy neutral buildings. Right now a passivhouse is the most economical compromise between construction costs and operating costs.
