来自事务所的描述：天与地之间的住宅—设日晷的被动式房屋

这座在日本的住宅是设日晷的被动式房屋。通过被动系统的运作在内部空间营造出一个舒适的冬暖夏凉的生活环境。这种生态技术有助于被动系统对太阳和风的利用，从而进行有效的空气调节。有了这个内置的日晷，时间可以通过顶光投影出的线条来显示。此外，日晷对这座住宅内部空间的作用，也提醒着我们天父的存在。

From the architect. Home between Earth and Sky- Passive house with Sundial.
This home in Japan is passive house in where a sundial is set. By adapting the passive system the internal spaces support a comfortable environment where in summer it is naturally cool and in the winter it is warm. This ecological technology aids this passive system using the sun and the wind for an effective air conditioner. With this built-in sundial, the time can be told through the line drawn by top light. Furthermore the sundial enables internal space of this house to remind us existence of Father Sky.

这一特色项目的建造过程经历了三个阶段：

1. 设日晷的被动式房屋的原型设计

首先，我们必须将被动式房屋作为一种直接获取系统。窗户被设置在建筑南立面，因为这面的屋檐夏天的时候能遮挡强烈的阳光，而在冬天的时候能接受阳光照射。同时在墙壁上也安装了隔热层。为了安装日晷，屋顶被设计成34.60°倾斜。屋顶之下的半圆柱体也做了相同角度的倾斜，在圆柱中心的上方设置了天窗，通过光线的位置可以知道时间。

The process of constructing this feature went through three steps:
1. Designing the prototype of the passive house with sundial
At first we must plan the passive house as direct gain system. The window is based on the south side where the eaves shut off the intense sunlight in summer while receives it in winter. Meanwhile insulation has been installed in the walls. For setting the sundial, the roof is inclined at the latitude of the site [34.60°]. Under the roof we put the half cylinder inclined at the same angle and above the center of the cylinder, the top light is set where the time can be told through the position of the line.

2. 适应场地环境

该建筑所在的地块是一个不规则的形状，日晷建筑朝南设置，也能获得不同方向的欣赏花园的视野。场地从西到东有一个较缓的坡度，厨房、办公和起居室的一半空间都位于距地面1米以下。建筑主入口在东侧，朝向该地区的池塘、丘陵和历史悠久的风景。

2. Adapting to the site environment
The site has an irregular shape, and as a result of putting the sundial facing south, there are a diverse number of views to the gardens. The site has a gentle slope from west to east, and the floor level of kitchen, atelier, half area of living room is at -1000mm from ground level. The main opening has been oriented to the east where it faces onto the ponds, hills and historic scenery in the area.

3. 朝向规划

设日晷的被动式房屋被分为两个区域。较明亮区域包含了起居室和厨房。同时，面向北侧的另一区域设置成工作室，而在两者之间的一些小空间，如浴室和厕所则按东、西轴线布置。

3. Planning by orientation
The plan of passive house with sundial is divided into two areas. The brighter of the two contains the living and kitchen. Meanwhile, the other is north facing area in where the atelier is and between the two, small spaces such as the bath and toilet are set along the east and west axis.

日晷不仅能告诉我们时间还提醒我们宇宙的存在。对场地的适应也提醒着我们大地的温柔。我们生活在地球母亲的怀抱中。我们生活在天父的庇佑下。我们生活在宇宙之中。在这个家里，我们可以感受到我们生活在宇宙中。这就是为什么我们要以“天与地之间的住宅”来命名这座房子。

The sundial tells us not only time but also existence of cosmos. Adaptation to the site reminds us the gentle of earth. We live on the Mother Earth. We live under the Father Sky. We live in the Universe. In this home we can feel that we live in the Universe. That is reason why we name this house“Home between Earth and Sky.”
