Text description provided by the architects. House of Maple Leaves

这是一座别墅，距离东京大约一个小时的火车路程，地点是日本的一个山村。它基本上是一个木制的结构，周围的阳台都是钢的。这一设计是根据京都著名的Katsura帝国别墅采用的被动能源原理设计的。

This is a villa situated about an hour’s rapid train ride from Tokyo in a mountain resort of Karuizawa, Japan. It is basically a wooden structure with the peripheral balconies in steel. The design is adapted from passive energy principles applied in the world-famous Katsura Imperial Villa in Kyoto.

唯一人工操作的系统是地板内的辐射热水加热，运行整个长度的周边开窗与热泵空调机组作为补充，以防万一。法律和有约束力的设计准则，在该地区要求屋顶斜率1：5最小，屋檐长度最小5OO毫米，和有限的选择外部着色。

The only artificially operated system is the radiant hot-water heating embedded in the floor, running the entire length of the peripheral fenestration with heat pump air conditioning units as supplements just in case. Legal and binding design guidelines in the area required a roof slope of 1:5 minimum, eave length of 5oo mm minimum, and a limited selection of exterior coloring.

14)高绝缘天然日本灰泥(嵌入枫叶)

14) Highly insulating natural Japanese stucco (with embedded maple leaves)

(15)地板、家具、橱柜、门和壁橱用叠层竹子代替木材，因为竹子生长很快(因此比木材更生态)，在日本也非常丰富。

15) Use of laminated bamboo instead of wood for floors, built-in furniture, cabinets, doors, and closets, as bamboo is very fast-growing (and hence more ecological than wood) and profusely abundant in Japan)

16)荧光灯和LED灯的使用

16) Use of fluorescent and LED lights

17)波纹金属外饰面，便于维护和可持续性。
