The meaning of BIM for Sekisui House

The History of Sekisui House CAD System evolution
has been like BIM Approach
BIM at Sekisui House is ・・・
By building a common platform for house assembly data
and residence data, BIM‐like
BIM like thinking is used to recreate
the optimal work process of the whole company

Optimizing and Re-creating Company Workflow

that are common and shared by design, costestimation, and ordering

Using standard assemblies fromstandard assembly DB and checking
design details to reduce design
mistakes.

SIDECS and SEPIAS using thecommon assembly DB, the house
data becomes unified andcontinuous

Ordinaryy smart house or smart
town provides solar energy
generation or fuel cell to powerhome appliances and electriccars as a means of eco smart

In 2010, Ministry of Internal Affairs andCommunications commissioned Sekisui
House to build the experimental house,“Kankan Kyo”, in Yokohama to implement
various environmental technology initiative.
Not only a smart house, but a new smart

Harmony between People and Their Home Through BIM
PeopleHouse is an “object” that has no intelligence. When
this house “object” has the highest performance, it canprovide the most comfort to its dwellers. Currently, smart
house represent the best type of house to deliver
performance, and is slowly becoming the standard.
However, as the dweller lifestyle changes or when thehouse changes hand, house as an “object” cannot adjust
accordingly.

Home

Theme: Harmony between People andTh
Their HHome
As time goes by, people change their thoughts andactivities as affected by the surrounding environment. A
home may begin with a couple. Before you know it, thehouse will be filled with children’schildren s laughter.
When the family grows, the lifestyle changes. The
home that has been spacious and comfortable may longer
be the case.
