Green Architecture


Read this overview of green architecture.

During the last decade, a strong interest in developing "green" architecture has emerged – designs that incorporate ecologically and environmentally sustainable practices in site preparation, materials, energy use, and waste systems. Some are simple: buildings oriented to the south or west help with passive solar heating. Others are more complex: Solar voltaic cells on the roof generate power for the building. Green roofs are made of sod and other organic materials and act as a cooling agent and recycle rainwater. In addition, technological innovations in lighting, heating, and cooling systems have made them more efficient.

A branch of the Seattle Public Library uses green design. A glass curtain wall on the north side makes use of natural lighting. The overhanging wooden roof beams shade harsh light. The whole structure is nestled under a green roof of sod and over 18,000 low-water use plants. Seven skylights on the roof provide more natural lighting.

The Jean Marie Tjibaou Cultural Center on the island of New Caledonia in the South Pacific captures the prevailing winds in sail-like structures that disperse it to the building's interior as passive ventilation. Architect Renzo Piano's design is influenced by the indigenous tribal culture of the island.
