We have to be concerned about reducing environmental impact in every stage, from product development, component production, processing and residential use, to renovation and dismantling, especially in the area of residential use, which often increases impact.

(Procurement) When procuring materials for building houses, delivery trucks create CO2, which affects global warming. It is also important to procure materials with less environmental impact.

(Production) Procured materials are processed into housing components at a factory. These processes consume energy, emit CO2, produce waste, and use chemical substances. Therefore, we need to control and reduce the levels of these emissions.

At building sites, vast amounts of byproducts are generated. Housing manufacturers face a huge task to reduce and recycle these byproducts, as well as to try to reuse them.

Energy consumption in a residence accounts for 70% of all lifecycle energy, and greatly affects global warming. Also, a home should be a healthy, safe, and comfortable place for residents, as well as for the environment.

A residence can be made livable for a long period by renovating it and enhancing its value. Also, it is necessary to design goods and develop processes to keep down waste generation when renovating and dismantling houses.
