- It can be rotated in any speed and direction.
- It saves the energy by controlling directions of the room; you can obtain/avoid the sunlight.
- You can fully enjoy the nature, 360 degree panoramic view, wind, and the smell of the air.
- -The purpose is to examine the effect of reduction for air-conditioner energy which is achieved by one floor's rotating.
- -The effect of reduction for air-conditioner energy should be examined by the comparision with the case of the floor's fixed due south(not to get direct rays, it should rotate once par a day).

- -floor rotates to avoid direct rays to the windows of living room and bed room.
- -The floor is supposed to rotate once in a day and other conditons are the same as the case of due south fixed.
- -Cooling load was used with SMASH* Ver2.1.3 in each case.
- -Air-condition in air conditioner area is supposed to use as normal air-conditioner in the room and the result was showed with electricity consumption.(COP of room air-conditioning was set to "3".)
- -The electricity consumption of the rotating motor is approximately 1.8kWh for turns around and the result is multiplied by the numbers of days which cooling load occured.
- *SMASH：Heat load calculation program for house
- -By Dio-ARC (rotating the floor), the electricity consumption of air conditioner is reduced 1,451kWh par year and the effect is approximately 34% reduction.
- -The electricity consumption for Dio-ARC (rotating the floor) became approximately 603kWh par year.
- -Yearly estimation of the electricity consumption which is needed for air-conditioner and Dio-ARC (floor rotation) became approximately 4.3MWh for due south and 3.5MWh for rotating.
- -Therefore, by Dio-ARC (rotating the floor), the consumption of air conditioner which is fixed due south got the effect of approximately 34% reduction.
