Shioashiya - the city has zero energy consumption

Launched in 2012, Shioashiya, the first smart city in Hyogo Prefecture, Japan, covers an area of ​​over 120,000 square meters, accommodating about 9,000 people.

Here, every house and public utility, as well as the master plan, is designed to minimize energy consumption and optimize the opportunity to use renewable energy.

Every house in Shioashiya is equipped with roof solar panels, storage batteries, and an intelligent management system - programmed to allow homes to use renewable energy when given the opportunity, and have can share with neighboring houses; Household appliances also automatically turn off when not in use.

Besides, the architecture of isolated houses also aims to reduce energy consumption, thanks to Puretech special insulation technology and Eco-Navi ventilation system , making the house cooler in the season. summer and warmer in winter, but without electricity.

PanaHome also turns Shioashiya's inner apartment complex into a zero-energy net by installing rooftop solar power generation systems and fuel cells inside each apartment. Each fuel cell is a source, generating electricity from the chemical reaction between hydrogen and oxygen - this type of energy is very welcome because it is clean, compared to traditional fossil fuels.

Thanks to the innovative infrastructure, including many generations of clean, renewable energy, Shioashiya's complex apartment can generate about 199 Mwh of electricity a year - exceeding the demand for all real estate. In the city, and the surplus of electricity can be sold to other places, generating an annual income of about $ 11,700 for the management association, PanaHome said.

Besides the residential area, the Solar-Shima Terrace community center is also equipped with solar power, battery storage, and the city master plan itself has also greatly reduced energy consumption activities. quantity. This is due to the fact that PanaHome used a special architectural technique - a passive design, to make the most of wind and sunlight. Due to its location between the sea and the mountains, the wind source around Shioashiya is extremely rich - helping to cool, ventilate and illuminate buildings in the city.

'PanaHome's solutions such as energy-free homes, smart energy management systems and new types of energy have the potential to help Japan achieve its goal of reducing energy consumption and emissions. , while bringing to the population a community that is worth living, sustainable, lively and comprehensive ' - according to Kazuhiko Tanaka, executive director of Asia-Pacific PanaHome.

'Shioashiya-equipped technologies are also ideal for scaling up across Japan, and for other Asian countries are also pursuing energy efficiency in their cities and buildings. ' Tanaka added.
