The sustainable design starts from the coexistence with the
nature. Besides the direct and specific sustainable design such
as energy saving, low carbon emission and resources recycling,
energy- efficient design becomes on demand in terms of design
process, construction, and maintenance. As far as the
sustainable design is concerned, appreciation on the
characteristics of the land and the climatic environment should
come first. Especially, in South Korea with distinctive four
seasons and large temperature differences in the summer and
winter, it is critical to utilize the passive design in spring
and autumn to minimize energy consumption. To that end, the
targeted amount should be set first, and then, the passive
design be applied to minimize the excess load to create the
pleasant indoor environment as much as possible. This, in turn,
leads to the utilization of the active design and renewable
energy. Green Tomorrow has implemented the environment-friendly
approaches by the passive design in its initial schem
