Yoyogi Sangubashi Terrace is a rental apartment planned in central Tokyo. From the building's façade to the courtyard, the design is full of plants, taking into consideration the biodiversity of the surrounding area. By bringing daylight, breeze, and greenery into the residential units through the courtyard, we realized more comfortable living space and improve the quality of life. Plus, by adopting a high-efficiency MEP system and setting extremely high envelopment performance, we have made it a super-low energy building which reduce 76% primary energy comsumption comparing to baseline.
