Sustainable Architecture

The use of the word, "sustainable architecture" became common in society in the 1990s, and various attempts to improve the environment were implemented. Yet, completed architecture has not necessarily been used as intended by designers in many cases. There is a discrepancy between the wishes of producers and users. This means that merely fitting buildings with environmental infrastructure is insufficient for creating sustainable buildings.

Individual buildings can only reduce a small amount of CO₂ emissions, but the accumulation will amount to large reductions.
The important thing is to build a consensus between users and produces on how environmentally-friendly efforts are to be incorporated into buildings, and how the buildings are to be used. This is the true key to sustainable architecture, and building consensus is one of the missions assigned to designers.

Nature is not a property inherited from ancestors, but rather one borrowed from our descendants.
We believe that environmentally-friendly architecture reflecting the wishes of users and producers is truly sustainable architecture.
