2. Striped plan configuration

Zones for various activities performed in the house are arranged in a stripped plan.

3. Piled up sectional configuration

Openings for natural lighting and entrances and exits for people and air currents are piled up vertically to fill the house with natural light and fresh air.

4. Modes

Building modes appropriate to the season and lifestyle are actualized by opening and closing the layers of various performances.

5. Use of natural energies

The open facade toward the south and the ventilation towers on the northern side let in light and fresh air.

6. Thermal environment and space configuration appropriate for each activity

Rooms in the house are arranged so that the conditions are appropriate for the activities performed in the room.

1. Simulation of thermal conditions

Thermal conditions are reproduced by using 1)air-conditioning and heating loads, 2)temperature changes, and 3) differences in temperature between rooms as evaluation items to estimate the heat insulation and other performances of the openings and the building.

2. Simulation of air flows

The size of openings and the shape of the roof are determined by investigating the distributions of airflow velocity for different positions of openings and different shapes of the roof by mainly using the dominant wind direction in spring, autumn and summer and conducting CFD (computational fluid dynamics) analysis.

3. Simulation of lighting

Both natural and artificial lightings are reproduced, and the positions of windows and lighting fixtures are investigated so as to prevent glare in the southern rooms and determine efficient arrangements of highly efficient lighting fixtures (LED).

4. Investigation of initial CO₂ emissions

Construction materials and methods are investigated to reduce the (initial) CO₂ emissions accompanying the construction.
