Text description provided by the architects. House of Maple Leaves

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.

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.

8) Allowing low winter sun penetration and blocking high summer sun

9) Use of deciduous trees in the south similarly allowing low winter sun penetration and blocking high summer sun

10) Extended eaves to provide shade

11) Double floor living space to act as passive solar collector

12) Fireplace in the living space to burn trash

13) Ceiling fans to circulate warm air

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

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) Use of fluorescent and LED lights

17) Corrugated metal exterior finish for easy maintenance and sustainability

18) Reflective silver roofing for insulation and temperature control
