The Verification and Implementation of Practical Renovation for net-ZEB Office
In Japan, energy-saving renovation of existing buildings has become an urgent issue. In the Japanese stock office buildings, the offices that less than 10,000m2 accounts for 98%. On March, 2016 Authors designed and completed the renovation for net-ZEB office in the local city Chiba near Tokyo. We introduced various technologies and reduced the energy consumption by approximately 70%. And we created renewable energy to exceed the remaining energy consumption, and it is expected to achieve a plus energy building. The concept of this renovation project are (1) variety of comfort, (2) super energy saving, (3) work smart, (4) disaster resistance. Without the use of fossil fuels as much as possible, we adopted radiation air conditioning and desiccant air conditioning using geothermal heat and solar heat. And it is characterized by the combination of maximum daylighting and natural ventilation. We were carried out wellness air conditioning control based on the metabolic rate and comfort declaration of workers. We report the effect of the energy reduction by re-design to change work-mode and use of various spaces, and the effect of the energy reduction by fa(c)ade renovation. This office has achieved a plus energy up to now, and we report the verification result of one year. At last, we consider about the essence of the ZEB renovation from LCCs point of view.
