Energy positive ‘powerhouse’

Many companies around the world are engaged in research and development in order to popularize “ZEB,” which is one of the measures to reduce greenhouse gas emissions to zero. ZEB is a general term for net zero energy buildings, which are buildings that aim to reduce the energy consumption of buildings while realizing a comfortable indoor environment. But simply, the electricity consumption for people to work in a building cannot be completely reduced to zero. In order to achieve this, it is necessary to reduce the amount of electricity used in the building and to generate the electricity used in the building itself. The result is virtually zero electricity usage in the building.
