Energy Zero Housing EZ House

Houses that reduce energy use by minimizing overall energy production and annual losses

  •  The energy can be produced by the solar panel, and it can produce up to 60% of the electricity used by 121 households including 3 apartment buildings, tenement houses and single-family houses.
  • There is an electric blind outside the terrace. In winter, people raise the blinds to raise the temperature of the room by the sun, and in the summer, people keep the temperature by blocking the sun with the blinds.
  •  condensation is likely to occur between the cold concrete outer wall and the inner insulation in the winter, which inevitably lowers the thermal effect. It is the technology of energy-zero housing that minimizes using energy while producing energy in an environmentally friendly manner.
