天地之间的家–带日晷的被动房。
这个位于日本的住宅是被动式住宅，其中设置了一个日晷。通过调整被动式系统，内部空间支持了一个舒适的环境，在夏天是自然凉爽的，在冬天是温暖的。这种生态技术帮助这种被动式系统利用太阳和风作为有效的空气调节器。有了这个内置的日晷，就可以通过顶部的光线来判断时间。此外，日晷使这个房子的内部空间提醒我们天父的存在。
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.
建造这个功能的过程经历了三个步骤：
1. 设计带日晷的被动房的原型
首先，我们必须将被动房规划为直接增益系统。窗户设在南侧，屋檐在夏天关闭强烈的阳光，而在冬天接受阳光。同时，在墙壁上安装了隔热材料。为了设置日晷，屋顶按照场地的纬度[34.60°]进行了倾斜。在屋顶下，我们把半圆柱体倾斜成相同的角度，在圆柱体的中心上方，设置了顶灯，通过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
场地有一个不规则的形状，由于把日晷朝向南方，有多种多样的花园景观。场地自西向东有一个缓坡，厨房、工作室、客厅的一半区域的地面离地面有-1000mm。主要的开口朝向东部，面向该地区的池塘、山丘和历史风景。
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. 按方向规划
带日晷的被动房的平面图被分为两个区域。两个区域中较亮的区域包含客厅和厨房。同时，另一个朝北的区域是工作室所在的地方，在这两个区域之间，沿东西轴线设置了一些小空间，如浴室和厕所。
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.
日晷不仅告诉我们时间，也告诉我们宇宙的存在。对场地的适应提醒我们地球的温柔。我们生活在地球母亲上。我们生活在父亲的天空下。我们生活在宇宙中。在这个家里，我们可以感觉到我们生活在宇宙中。这就是为什么我们把这个房子命名为 “天与地之间的家 “的原因。
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.’
