A new Smart House construction project of a multi-dwelling complex took place in a housing complex area in Yokohama City.
Optimization and stable supply of energy are ensured with the proactive use of natural energy and renewable energy while the energy consumption is measured and visualized. As a part of Yokohama Smart City Project (YSCP), this demonstration project aims to achieve a next-generation energy and social system.
< Passive elements >
1) The building layout that takes account of the ventilation and wind exposure from the prevailing wind direction as well as the solar radiation exposure in the winter.
2) Installation of ventilation windows that allow breeze to enter, beams that serve as heat accumulators, and a flat ceiling without hanging partition walls.
3) The restoration of satoyama (woodlands in the vicinity) by the re-introduction of native species and the creation of an intermediate zone that links the interior and exterior through the establishment of public, private, and rooftop gardens.
< Active elements >
1) 4 households share the hot water generated by 2 Ene-Farms.
2) Introduction of a solar power generation system and a gas-fired hot water system utilizing solar heat (SOLAMO).
3) Energy visualization with HEMS.
This Smart House combines the passive elements that work in conjunction with the natural environment and active elements that improve energy efficiency.
