Earthquake Resistant

In extremely rare cases of earthquakes, for planning facility improvements for continuous utilization, and for the decrease of damage, the following steps are required.

1.Earthquake resistance Level 2 Checklist: Wall quantity for performance,
 Wall Arrangement, Floor Magnification, Connecting Joints,
 Horizontal Member, Foundation.
2.The Ratio for Safety Limit Deformation of each floor of a structure during
 a major earthquake is less than 1/4(check inter-layer deformation angle)
3.to assume as base isolated building.

Energy Saving

Energy- saving heat insulation. It should meet energy conservation provisions prescribing energy conservation standards.

Counter- measures for Saving Energy Level 4
a)Performance Code (amount of Q, preventation of dew)
b)Specifications(amount of U)

Easy Maintenance

Necessary measures should be taken for easy maintenance of shorter life spanned interior and  the equipments (cleaning, check-up, repair, renewal)

Necessary measures should be taken for maintaining the plumbing without influencing the structural body of the building during construction.

Deterioration Prevention

Utility of the structural body for the coming generation.

In addition to preventing deterioration, it’s important to secure inspection holes under the floor and attic space with 330 mm. or more of effective height.

Dwelling Unit
