energy use and without detrimental environmental
pollution during its lifespan.

NET ZERO REDUCT - a structure which follows a

energy use and without detrimental environmental
pollution during its lifespan.
CRADLE TO CRADLE- a material or assembly which
can be easily returned to earth or recycled into the
same material for use at the end of its life-cycle.
Organic = biodegradable (carbon based)
Inorganic = non-living, not carbon based (i.e. mineral)
NATURAL(ly) NET ZERO
• all natural
• local and low cost materials
• easy to construct
• zero emissions in material
manufacture and transportation
• biodegradable or recyclable
• fire pit and lamp aside – net zero
