Sustainable Architecture Museum is actually a reference standard of sustainability itself. Almost all of its structures were made of natural and durable but mostly cheap materials.
Gabions filled with white rocks are its cornerstones, and gilded metal net is corrosion-proof and makes the facility look very elegant.
Lots of glass (and even the ceiling is made of glass) helps to save lighting and offers great views of the sky, stars, and the surrounding grounds.
Part of the building is located below the ground level, which saves energy in terms of heating and cooling.
